Regardig Field Length in ALV
I am trying to set the field length in ALV
so i wrote
<fs_fcat>-outputlen = 15.
and in layout...
wa_layout-colwidth_optimize = space . tried by commenting this statment also
But it doesnt show any effect
" in fact field length is depend on field lable and on its content..."
so plz help me some buddy.....

Hello,
Try updating the description fields of the Fieldcat records prior to defining the outputlen field. Depending on the way you are implementing your ALV, try updating the following fields:
scrtext_l
scrtext_m
scrtext_s
or
seltext_l
seltext_m
seltext_s
Best regards,

Field Length in Alv Grid out put
hi,
How to increase the length of the filed in the output of alv grid,
Actually i am getting one blank field in the alv grid out put, my requirement is to increase the length through out the column how to do that
can anyone guide me plz
SIRIin your fieldcat of the field
wfieldcat-fieldname = '<your fieldname in caps>'
wfieldcat-outputlen = 10 (or the length you want for the field)
<you can define any other property also for that field>
append wfieldcat to ifieldcat.
now pass it in fm.

Reduce out put field length of alv output in back ground
Hi all,
Is there a way to reduce the output length of the field in back groundfor ALV out put
Its back ground
I have thsi things in my field catalog
wa_fieldcat-outputlen = 10.
wa_fieldcat-ddic_outputlen = 10.
If the field has value of length 10 characters its ok
but when the field has lenth of more than 10 characters
(say 20 char). in fore ground it displays 10 characters and then we can move the column to see full thing , but in back ground it displays 20 char.
In fact that is what i have to see because in background you cannot drag the column to see entire thing , but i want to cut short to 12 char even if i don't see the remaining thing its ok
ThanksHi Vasu,
WHAT EXACTLY SY-BATCH DOES .
I tried reducing wa_fieldcat-outputlen = 10. and then i tried
wa_fieldcat-outputlen = 5., but it doesnot really changed anything in back ground but it did in fore ground . I haven't used any called sy-batch
Let me know
This is how my field catalog looks for mATNR
clear wa_fieldcat.
wa_fieldcat-fieldname = 'MATNR'.
wa_fieldcat-seltext_l = ' Material #'.
wa_fieldcat-seltext_m = 'Material #'.
wa_fieldcat-seltext_s = ' Material #'.
wa_fieldcat-reptext_ddic = 'Material #'.
wa_fieldcat-ddictxt = 'L'.
wa_fieldcat-col_pos = 4.
wa_fieldcat-outputlen = 18.
wa_fieldcat-intlen = 18.
wa_fieldcat-ddic_outputlen = 18.
wa_fieldcat-tabname = '1'.
append wa_fieldcat to fieldcat.
NEXT TIME I COMMENTED THIS AND HAD
wa_fieldcat-fieldname = 'MATNR'.
wa_fieldcat-seltext_l = ' Material #'.
wa_fieldcat-seltext_m = 'Material #'.
wa_fieldcat-seltext_s = ' Material #'.
wa_fieldcat-reptext_ddic = 'Material #'.
wa_fieldcat-ddictxt = 'L'.
wa_fieldcat-col_pos = 4.
wa_fieldcat-outputlen = 10.
wa_fieldcat-intlen = 10.
wa_fieldcat-ddic_outputlen = 10.
wa_fieldcat-tabname = '1'.
append wa_fieldcat to fieldcat.
BUT I DID SEE DIFFERENCE IN FOREBROUND BUT NOT IN BACK GROUND
Let me know
Thanks -
hi experts,
i have a small doubt in alv.
In fieldcat i have one field called amount and am defining its length 19.
but actual its length in database is 14.when i tried to display the this amount field using reuse_alv_list_display the data in amount field is showing only 14 digits,but i need to display its total length(even if it is greater than database length).........
correct answers rewarded with maximum points????????????Hi
Check while preparing Fieldcatalog you are giving length 19 to this amount fields .
For this u have a option of output length in fieldcatalog .
Try this .
Hope this helps .

hi,
if we increase the length of field using <b>outputlen</b> with fieldcatalog.
if i do it that length is applicable for data as well as for text.......
example:
balance(17).
but with this balance field i want to display amount more than 17 characters....
is it possible with ouputlen option of fieldcatalog........move that field to some bigger variable. and display that bigger variable.
Say,
data: amt(32) type p decimals 2.
than
itab-amt = itab-balance.
modify Itab
Dispaly itab-AMT instead of the itab-BALANCE.

To display text field with more than 1000 length in ALV
Hi Friends,
I need to display material long text field which is more than 1000 length in ALV or Object oriented ALV.
Please help me to resolve the issue.
Regards,
Jaya.Hi,
U mean to say in a single cell of ALV ??
It is not possible in ALV .. As per OSS note 857823
Below is the reason for same.. I think you should to split in number of columns.
Summary
Symptom
Entries in cells of the type CHAR or string are truncated after 128 characters in the SAP GUI.
Other terms
ALV Grid Control (cl_gui_alv_grid), function module (Full-screen)
Grid (Reuse_alv_grid_display, SAPLSLVC_FULLSCREEN), SAPGUI, back end, front end
Reason and Prerequisites
The data table that is sent to the front end only allows character values with the length 128.
Solution
This is the standard system behavior and cannot be changed. -
ALV (Factory class) field length problem
Hi experts!
I build an ALV report using the Factory method. But I can't set the field length.
When I set the field length in a column attributes it doesn't change nothing
What is the problem?
My column attributes are like that:
TRY.
lr_column ?= lr_columns->get_column( 'NAME1' ).
lv_text_s = text-103.
lv_text_m = text-103.
lv_text_l = text-103.
lr_column->set_long_text( text-103 ).
lr_column->set_short_text( lv_text_s ).
lr_column->set_medium_text( lv_text_m ).
<b> lr_column->set_output_length( 30 ) .</b>
lr_column->set_active_for_rep_interface( gc_default ).
CATCH cx_salv_not_found.
ENDTRY.

How to display a field that has more than 136 char length in ALV GRID
Hi Experts,
I have an issue and need to solve ASAP.
I want to display a text of length 400 character in a particular column in ALV GRID DISPLAY. After executing the report it is displaying only 136 length char in the output and when I download the report to an excel it is showing only 255 characters, but my field length is almost 400 char and want to display in the report output.
I checked in SDN and didnt get any answers which will solve this.
Please help me to complete this issue.
Thanks
RetheeshCurrently I'm in a same problem with you.
And this is what I found
Size of data fields: While the list-based ALVList can display only tables of up to 90 columns, the control-based *ALVGrid and ALVFullscreen have a limitation of 128 characters per data cell.*
So it means that maximum for alv grid is only 128.
Please refer to this documentation
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/4544e790-0201-0010-c29c-e46c389f5a96]
you can find the statement above in page 5.
Please let me know if you have another solution, because I would like to see it too.

Hi Friends,
Please help me out, I am new to ABAP.
Please anybody explain me the functionality of Field catalogs in ALVs?
How many methods are there to pass data to ALVs, i.e., in how many ways?
Hope u will help me.hi,
this will be very helpful for ALV REPORTING.....
Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain upto 90 columns in the display with the wide array of display options.
The commonly used ALV functions used for this purpose are;
1. REUSE_ALV_VARIANT_DEFAULT_GET
2. REUSE_ALV_VARIANT_F4
3. REUSE_ALV_VARIANT_EXISTENCE
4. REUSE_ALV_EVENTS_GET
5. REUSE_ALV_COMMENTARY_WRITE
6. REUSE_ALV_FIELDCATALOG_MERGE
7. REUSE_ALV_LIST_DISPLAY
8. REUSE_ALV_GRID_DISPLAY
9. REUSE_ALV_POPUP_TO_SELECT
The different steps used for getting the above function modules into use are:
Step 1
DATA DECLARATION
Sap standard type pools: SLIS , KKBLO .
Sap standard tables types taken from the type pools are: SLIS_LAYOUT_ALV ,
SLIS_T_FIELDCAT_ALV,
SLIS_T_LISTHEADER,
SLIS_T_EVENT,
SLIS_SELFIELD.
Internal tables to used in the program declared based on the above table types
DATA: I_LAYOUT TYPE SLIS_LAYOUT_ALV,
I_FIELDTAB TYPE SLIS_T_FIELDCAT_ALV,
I_HEADING TYPE SLIS_T_LISTHEADER,
I_EVENTS TYPE SLIS_T_EVENT.
TYPES: KKBLO_SELFIELD TYPE SLIS_SELFIELD.
Step 2 (Optional)
SELECTING THE VARIANTS FOR INITIAL LIST DISPLAY (DEFAULT VARIANT)
The variants in the list display can be both user-specific and general. The user can programmatically set the initial (default) variant for list display.
The default variant can be found using the function module 'REUSE_ALV_VARIANT_DEFAULT_GET'.
Sample code:
CALL FUNCTION 'REUSE_ALV_VARIANT_DEFAULT_GET'
EXPORTING
i_save = variant save condition ( A=all, U = user-specific )
CHANGING
cs_variant = internal table containing the program name (and the default variant---optional )
EXCEPTIONS
not_found = 2.
The user can also choose from the list of existing variants using the function module REUSE_ALV_VARIANT_F4.
Step 3
DEFININING OUTPUT CHARACTERISTICS: PREPARING DISPLAY FIELDS CATALOG
A field catalog is prepared using the internal table (I_FIELDCAT) of type SLIS_T_FIELDCAT_ALV. Field catalog containing descriptions of the list output fields (usually a subset of the internal output table fields).
A field catalog is required for every ALV list output to add desired functionality (i.e. Key, Hotspot, Specific headings, Justify, Col. position etc) to certain fields of the output. If not mentioned specifically, then the defaults are taken. The possible values and defaults are listed below.
The field catalog for the output table is built-up in the caller's coding. The build-up can be completely or partially automated by calling the REUSE_ALV_FIELDCATALOG_MERGE module.
The minimal field catalog is documented below. This can be done in a routine using a local variable. The user can use the other optional parameters to assign output attributes to different fields in the output, which differ from the default.
A field catalog need not be built-up and passed explicitly only under the following conditions:
1. The internal table to be output has the same structure as a Data Dictionary structure which is referred to in the internal table declaration using LIKE or INCLUDE STRUCTURE. In this case the attributes of the different fields is taken directly from the table and the attributes (key fields, length, texts etc) need to state explicitly.
2. all fields in this structure are to be output
3. The structure name is passed to ALV in the parameter I_STRUCTURE_NAME of the function module REUSE_ALV_LIST_DISPLAY.
All the values entered in the catalog is specific to the particular field whose name is entered in the fieldname FIELDNAME of the fieldcat structure. The name of the table is also entered in the corr. Fieldname TABNAME of the structure.
The different possible attributes are:
Row_pos (row position): Only relevant if the list output is to be multi-line (two or three lines) by default. So, this attribute can be used maintain certain level of alignment in the output.
Value set: 0, 1 3
Col_pos (column position): This parameter is relevant when the fields in the output are to be different from the sequence of the fields in the internal table used for display. The parameter specifies the relative column position of the field in the list output. The column order can be changed interactively by the user. If this parameter is initial for all field catalog entries, columns appear in the internal table field sequence.
Value set: 0, 1 60
Fieldname (field name): This is the name of the internal table field for which the parameters are passed in the catalog.
Value set: internal output table field name (required parameter)
Tabname (internal output table): Name of the internal output table that contains the field FIELDCAT-FIELDNAME above.
Value set: SPACE, internal output table name.
Ref_fieldname (reference field name): Name of the Data Dictionary field referred to. This parameter is only used when the internal output table field described by the current field catalog entry has a reference to the Data Dictionary (not a program field), and the field name in the internal output table is different from the name of the field in the Data Dictionary. If the field names are identical, naming the Data Dictionary structure or table in the FIELDCAT-REF_TABNAME parameter is sufficient.
Value set: SPACE, Data Dictionary field name.
Ref_tabname (reference table/structure field name): Structure or table name of the referred Data Dictionary field. This parameter is only used when the internal output table field described by the current field catalog entry has a Data Dictionary reference (not a program field).
Value set: SPACE, name of a Data Dictionary structure or table
Link to currency unit
Cfieldname (currency unit field name): This is used for currency fields that have a reference to any unit field. This is only relevant for amount columns with associated unit. This parameter contains the Name of the internal output table field containing the currency unit associated with the amount field FIELDCAT-FIELDNAME. The field in FIELDCAT-CFIELDNAME must have its own field catalog entry.
Value set: SPACE, output table field name
Ctabname (internal currency unit field output table): Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
Value set: SPACE, output table field name.
Link to measurement unit
Qfieldname (measurement unit field name): Only relevant for quantity columns with unit link. Name of the internal output table field containing the measurement unit associated with the quantity field FIELDCAT-FIELDNAME. The field in FIELDCAT-QFIELDNAME must have its own field catalog entry.
Value set: SPACE, output table field name.
Qtabname (internal measurement unit field output table): Name of the internal output table containing the FIELDCAT-QFIELDNAME field.
Value set: SPACE, output table field name.
Outputlen (column width): This parameter is used if the desired output length for a field is desired to be different from the internal output table field. For fields with a Data Dictionary link this parameter can be left initial. For fields without a Data Dictionary link (program field) the parameter must be given the value of the desired field list output length (column width).
Initial = column width is the output length of the referred Data Dictionary field (domain).
N = column width is n characters.
Value set: 0 (initial), n.
Key (key column): By default, the system makes some fields in the output as key fields, provided the fields are key fields in their referencing table. Using this parameter, fields other than key fields of the referencing table can be made key field. This parameter is most important if the output needs to contain some field which are not scrollable or cannot be hidden.
If the internal output table contains fields that are key fields from different tables, then all those fields in the report output becomes unscrollable and cannot be hidden. So, the fields in the output internal table should not be referenced from tables in which they are key fields. Instead, they should be referenced to the tables in which they are not key fields, incase they are not desired as key field in the output.
'X' = key field (key field output in color) and Key fields can not be interactively hidden. Parameter FIELDCAT-NO_OUT must be left initial.
Value set: SPACE, 'X'.
Key_sel (hideable key column): This parameter is only relevant for the fields which are made key fields using FIELDCAT-KEY = 'X'. Using this parameter the Key field can be hidden interactively.
The key column sequence cannot be changed interactively by the user. The output is controlled by the FIELDCAT-NO_OUT parameter analogously to non-key fields.
Value set: SPACE, 'X'.
No_out (field in field list): This parameter is used to remove certain fields from the output during initial display. The user can however interactively choose the field for output from the field list in the display variant.
'X' = field is not displayed in the current list.
Value set: SPACE, 'X'.
Tech (technical field): This parameter is used to make certain field display only in the field catalog. The fields with this parameter set cannot be output in the list nor can they be displayed interactively from the catalog.
'X' = technical field.
Value set: SPACE, 'X'.
Emphasize (highlight columns in color): As name suggests, this field parameter is used to highlight certain field with chosen colors.
Value set: SPACE, 'X' or 'Cxyz' (x:'1'-'9'; y,z: '0'=off ,'1'=on).
'X' = column is colored with the default column highlight color.
'Cxyz' = column is colored with a coded color:
- C: Color (coding must begin with C)
- X: color number
- Y: bold
- Z: inverse
Hotspot (column as hotspot): This parameter is used to make certain field appear as hotspot i.e. a hand is displayed if the cursor is positioned on the field value. Single click on such fields cause the PICK OR F2 events to happen.
Value set: SPACE, 'X'.
'X' = column cells are output as hotspots.
Fix_column (fix column): This parameter is used to fix certain columns in the output. All columns to be fixed must have this flag, starting from the left. If a column without this flag is output, only the columns to the left of this column are fixed. The user can change the column fixing interactively.
Value set: SPACE, 'X'.
'X' = column fixed (does not scroll horizontally).
Do_sum (sum over column): the user can also call this function interactively.
Value set: SPACE, 'X'.
'X' = a sum is calculated over this internal output table field.
No_sum (sums forbidden): No sum can be calculated over this field, although the data type of the field would allow summing.
Value set: SPACE, 'X'.
Icon: The parameter displays certain column contents as icons. The internal output table column contents must be valid icon strings.
Value set: SPACE, 'X'.
'X' = column contents to be output as an icon.
Symbol: The internal output table column must be a valid symbol character.
Value set: SPACE, 'X'
'X' = column contents are to be output as a symbol.
Just (justification): This parameter is used for alignment of the contents of the output table. This is only relevant for CHAR or NUMC fields in the output internal table. The justification of the column header always follows the justification of the columns. Independent justification of the column header is not possible.
Value set: SPACE, 'R', 'L', and C.
' ' = Default justification for this data type
'R' = right-justified output
'L' = left-justified output
'C' = centered output.
Lzero (leading zeros): By default ALV outputs NUMC fields right-justified without leading zeros. Using this parameter only the NUMC fields can be displayed with leading zeroes.
Value set: SPACE, 'X'.
'X' = output with leading zeros.
No_sign (no +/- sign): This parameter is used to suppress the signs of the output fields. It is only relevant for the value fields.
Value set: SPACE, 'X'.
'X' = value output without +/ sign.
No_zero (suppress zeros): Only relevant for value fields.
Value set: SPACE, 'X'.
'X' = suppress zeros.
Edit_mask (field formatting): To apply the report output formatting options same as in the WRITE statement in report writing.
Value set: SPACE, template.
The following parameters are used for customizing the texts in the heading of the output of the columns. The texts are taken from the Data Dictionary for fields with a Data Dictionary reference. If this is not desired, the text parameters can also be specified. The Data Dictionary texts are then ignored.
If the user changes the column width interactively, the column header text with the appropriate length is always used.
The interactive function 'Optimize column width' takes account of both the field contents and the column headers: if all field contents are shorter than the shortest column header, the column width depends on the column header.
The 'long field label' is also used in display variant definition,
Sort, etc. Popup.
seltext_l (long field label)
seltext_m (medium field label)
seltext_s (short field label)
reptext_ddic(header) Analogous to the Data element main header
Ddictxt (specify text) : You can specify with values 'L', 'M', and 'S', the keyword that should always be used as column header. If the column width changes, no attempt is made in this case to find an appropriate header for the new output width.
Value set: SPACE, 'L', 'M', and S.
Sample code:
Suppose I_PO_DETAILS is an internal table containing two fields EBELN (PO number) and EBELP (PO item no).
DATA: L_FIELDCAT TYPE SLIS_FIELDCAT_ALV. Local variable to hold the parameters
for a particular field of the field catalog
CLEAR L_FIELDCAT.
L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
L_FIELDCAT-FIELDNAME = 'EBELN'.
L_FIELDCAT-KEY = 'X'. The PO no is made the key field,
Colored and non scrollable
L_FIELDCAT-HOTSPOT = 'X'. The po no becomes a hotspot
L_FIELDCAT-SELTEXT_S = P.O No.
L_FIELDCAT-SELTEXT_M = 'P order No'.
L_FIELDCAT-SELTEXT_L = 'Purchase order No'.
APPEND L_FIELDCAT TO I_FIELDTAB.
CLEAR L_FIELDCAT
L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
L_FIELDCAT-FIELDNAME = 'EBELN'.
L_FIELDCAT-KEY = 'X'. The po item no is made the key field,
Colored and non scrollable
L_FIELDCAT-SELTEXT_S = 'Item No'.
L_FIELDCAT-SELTEXT_M = 'Item No`.
L_FIELDCAT-SELTEXT_L = 'PO Item No'.
APPEND L_FIELDCAT TO I_FIELDTAB.
CLEAR L_FIELDCAT
Thus the catalog for the report output is prepared.
Step 4
The next step is to build an event table, which are used for firing both user commands and the system dependent events i.e. top of page, end of page etc.
A list of possible events is populated into an event table (I_EVENTS) when this table is passed to the function module REUSE_ALV_EVENT_NAMES_GET. The return table from this function module contains all the possible events.
The function module contains following import and export parameters.
IMPORTING PARAMETERS: I_LIST_TYPE
This parameter has possible values from 0-4.
The parameter I_LIST_TYPE is of TYPE SLIS_LIST_TYPE and is DEFAULT 0 .
EXPORTING PARAMETERS: I_EVENTS table.
This table is of TYPE SLIS_T_EVENT and returns to the program the name of all the possible events.
The table structure contains the fields:
I_EVENTS-NAME: Name of the Callback event.
I_EVENTS-FORM: Name of the form routine that should be called in the calling program at the event.
Only events with a form routine name are processed.
The I_EVENTS table returns with the following possible constants:
1. Slis_ev_item_data_expand TYPE slis_formname VALUE 'ITEM_DATA_EXPAND'.
Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT. Exit for passing item entries (ITEM table) for a header record that was expanded interactively by the user.
2. Slis_ev_reprep_sel_modify TYPE slis_formname VALUE 'REPREP_SEL_MODIFY'.
RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header that is to be expanded.
RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that entries are not repeated in the item table.
RS_SELFIELD is initial in this case.
3. Slis_ev_caller_exit_at_start TYPE slis_formname VALUE 'CALLER_EXIT'.
Is called at the beginning of the function module to make special settings. It is not usually used.
4. Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface by passing the user command in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
5. Slis_ev_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'.
Equivalent to the list processing TOP-OF-PAGE event.
6. Slis_ev_top_of_coverpage TYPE slis_formname VALUE 'TOP_OF_COVERPAGE'.
The selection information and list status are output together (if they exist) on a separate page by default
7. Slis_ev_end_of_coverpage TYPE slis_formname VALUE 'END_OF_COVERPAGE'.
Analogously to TOP_OF_COVERPAGE the user can add other information
to the information output by ALV (selection information, list status) at this event.
8. Slis_ev_foreign_top_of_page TYPE slis_formname VALUE FOREIGN_TOP_OF_PAGE'.
The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
9. Slis_ev_foreign_end_of_page TYPE slis_formname VALUE 'FOREIGN_END_OF_PAGE'.
The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
10. Slis_ev_pf_status_set TYPE slis_formname VALUE 'PF_STATUS_SET'.
If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
The STANDARD status of the function group SALV should be used as a template for a user-specific status. As this is a frequently used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
11. Slis_ev_list_modify TYPE slis_formname VALUE 'LIST_MODIFY'.
LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
R_INDEX LIKE SY-TABIX
R_INDEX_ITEM LIKE SY-TABIX
R_INDEX_SUM LIKE SY-TABIX.
12. Slis_ev_top_of_list TYPE slis_formname VALUE 'TOP_OF_LIST'.
Information output at the start of the list
13. Slis_ev_end_of_page TYPE slis_formname VALUE 'END_OF_PAGE'.
Information output at the end of a page. This is only called for printing.
14. Slis_ev_end_of_list TYPE slis_formname VALUE 'END_OF_LIST'.
Information output at the end of the list
15. Slis_ev_after_line_output TYPE slis_formname VALUE 'AFTER_LINE_OUTPUT'.
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
16. Slis_ev_before_line_output TYPE slis_formname VALUE 'BEFORE_LINE_OUTPUT'.
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
17. Slis_ev_subtotal_text TYPE slis_formname VALUE 'SUBTOTAL_TEXT'.
This event table (I_EVENTS) is now checked with the desired constants. If the desired constant is found, then the corresponding field for the FORM NAME is populated with the name of the routine containing the corresponding event.
Sample code :
FORMNAME_TOP_OF_PAGE TYPE SLIS_FORMNAME VALUE 'TOP_OF_PAGE',
FORMNAME_END_OF_PAGE TYPE SLIS_FORMNAME VALUE 'END_OF_PAGE', FORMNAME_USER_COMMAND TYPE SLIS_FORMNAME VALUE 'USER_COMMAND'.
DATA: L_I_EVENT TYPE SLIS_ALV_EVENT.
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
EXPORTING
I_LIST_TYPE = 0
IMPORTING
ET_EVENTS = I_EVENTS.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_TOP_OF_PAGE
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_TOP_OF_PAGE TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_END_OF_PAGE
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_END_OF_PAGE TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
CLEAR L_I_EVENT.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_USER_COMMAND
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_USER_COMMAND TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
This will prepare the events table for the report.
The report will contain three forms for the above events:
1. FORM TOP_OF_PAGE : This form will contain the top of page event for the report i.e header etc
Using the function module REUSE_ALV_COMMENTARY_WRITE, the internal table containing the headings for top of page event can be passed to the list output. Also, any logo specific to the report can be passed to the function module.
2. FORM END_OF_PAGE : This form will contain the end of page event for the report i.e footer etc
3. FORM USER_COMMAND : This form will contain the desired user command i.e pick/line selection
Step 5
A layout is build for the report output list description USING the internal table declared above (I_LAYOUT).
Output list description structure.
The parameters are described under the following heads:
Display options
Exceptions
Totals
Interaction
Detail screen
Display variants (only for hierarchical-sequential lists)
Color
Other
The layout table is of type slis_layout_alv_spec and has the following fields:
Display options
1. Colwidth_optimize (1) TYPE c: This parameter optimizes the length of the different columns in the output. The width of the different col. now depends on the max. Length of the data in the column.

Value set: SPACE, CHAR (20)
' ' = The header table field pushbutton text is 'Header' by default.
CHAR (20) = header table field pushbutton text.
43.item_text(20) TYPE c : Text for item button. Only relevant for hierarchical-sequential lists. You can toggle the view between the display fields and the field list via pushbuttons in the display variant definition popup for hierarchical-sequential lists.

Value set: SPACE, internal output table field name
The internal output table field must be of type CHAR(3).
The code must have the following syntax: 'Cxy':
C = color (all codes must start with 'C')
X = color number ('1'-'9')
Y = bold ('0' = off, '1' = on)
46. Coltab_fieldname TYPE slis_fieldname: Cells can be colored individually using a color code which is contained in a column of the internal output table for the record containing the cell. Assign the name of the field to this parameter.
Others
47. List_append(1) TYPE c : no call screen. It is only useful to output block-lists without specifying the above modules if the number of list blocks exceeds, or may exceed, the maximum number specified in the block module documentation. These operations are not possible for user-defined block lists.
Example code :
I_LAYOUT-f2code = ws_fcode.
I_LAYOUT-zebra = 'X'.
I_LAYOUT-colwidth_optimize = 'X'.
I_LAYOUT-no_keyfix = 'X'.
I_LAYOUT-get_selinfos = 'X'.
I_LAYOUT-no_hotspot = 'X'.
I_LAYOUT-no_input = 'X'.
I_LAYOUT-hotspot_fieldname = FIELDNAME.
I_LAYOUT-no_input = X.
I_LAYOUT-no_vline = `X.
I_LAYOUT-no_colhead = .
I_LAYOUT-lights_condense = ` `.
I_LAYOUT-totals_text = ` `.
I_LAYOUT-subtotals_text = ` `.
I_LAYOUT-totals_only = ` `.
I_LAYOUT-key_hotspot = X.
I_LAYOUT-detail_popup = X.
I_LAYOUT-group_change_edit = X.
I_LAYOUT-GROUP_BUTTONS = X.
Step 6
This step is required to get the selection screen information in the report output.
The prerequisite for this is to set the parameter LAYOUT-GET_SELINFOS of the IMPORTING structure.
The parameters to be passed in the IS_SEL_HIDE table are:
o mode: 'R' = only the entries passed in the internal table IS_SEL_HIDE-T_ENTRIES
Are output in the pop up. Selection info, which the list tool read in the selection screen (when called by a report with a selection screen), is replaced by the values passed.
'S' = the selection info which the list tool read in the selection screen of the calling report are modified by the entries in the table IS_SEL_HIDE-T_ENTRIES.
o t_entries: Selection info table
o t_entries-mode: 'A' = output the selection info for the current table record in the info popup.
'D' = do not output select option or SELNAME parameter selection info in the popup.
o t_entries-selname: (only used in t_entries-mode = 'D') : Name of the select option or parameter.
The following table fields are only used in t_entries-mode = 'A'. They contain the selection information to be added.
t_entries-field: DDIC field name of the field for which selection information is to be output.
t_entries-table: DDIC table names of t_entries-field.
t_entries-stext: Field name in info popup.
If t_entries-field and t_entries-table have been entered, this text is taken from DDIC.
t_entries-valuf: Selection condition 'from' value (external format)
t_entries-valut: Selection condition 'to' value (external format)
t_entries-sign0: (I)nclusive (E)xclusive
t_entries-option: All values of the select options Option field allowed.
Step 6
The Table IT_SORT is populated with the sort criteria for the different fields.
The caller specifies the sorting and/or subtotaling of the basic list in the internal table IT_SORT.
This internal table has the following fields:
o spos : Sort sequence
o fieldname : Internal output table field name
o tabname : Only relevant for hierarchical-sequential lists. Name of the internal output table.
o up : 'X' = sort in ascending order
o down : 'X' = sort in descending order
o subtot : 'X' = subtotal at group value change
o group : '* ' = new page at group value change ,'UL' = underline at group value change
Step 7
The final step in the output of the report is the use of two ALV functions modules.
1. REUSE_ALV_FIELDCATALOG_MERGE
2. REUSE_ALV_LIST_DISPLAY
The first function module is used to pass the field catalog to the report output and merge it with the internal output table.
FUNCTION reuse_alv_fieldcatalog_merge.

AT SELECTION-SCREEN-ON FIELD event IN ALV
Hai all,
Is there any event in ALV similar to AT SELECTION-SCREEN-ON FIELD .
if so how can this be achieved ,pls give me an example .
Regards,
DevSap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain upto 90 columns in the display with the wide array of display options.
The commonly used ALV functions used for this purpose are;
1. REUSE_ALV_VARIANT_DEFAULT_GET
2. REUSE_ALV_VARIANT_F4
3. REUSE_ALV_VARIANT_EXISTENCE
4. REUSE_ALV_EVENTS_GET
5. REUSE_ALV_COMMENTARY_WRITE
6. REUSE_ALV_FIELDCATALOG_MERGE
7. REUSE_ALV_LIST_DISPLAY
8. REUSE_ALV_GRID_DISPLAY
9. REUSE_ALV_POPUP_TO_SELECT
The different steps used for getting the above function modules into use are:
Step 1
DATA DECLARATION
Sap standard type pools: SLIS , KKBLO .
Sap standard tables types taken from the type pools are: SLIS_LAYOUT_ALV ,
SLIS_T_FIELDCAT_ALV,
SLIS_T_LISTHEADER,
SLIS_T_EVENT,
SLIS_SELFIELD.
Internal tables to used in the program declared based on the above table types
DATA: I_LAYOUT TYPE SLIS_LAYOUT_ALV,
I_FIELDTAB TYPE SLIS_T_FIELDCAT_ALV,
I_HEADING TYPE SLIS_T_LISTHEADER,
I_EVENTS TYPE SLIS_T_EVENT.
TYPES: KKBLO_SELFIELD TYPE SLIS_SELFIELD.
Step 2 (Optional)
SELECTING THE VARIANTS FOR INITIAL LIST DISPLAY (DEFAULT VARIANT)
The variants in the list display can be both user-specific and general. The user can programmatically set the initial (default) variant for list display.
The default variant can be found using the function module 'REUSE_ALV_VARIANT_DEFAULT_GET'.
Sample code:
CALL FUNCTION 'REUSE_ALV_VARIANT_DEFAULT_GET'
EXPORTING
i_save = variant save condition ( A=all, U = user-specific )
CHANGING
cs_variant = internal table containing the program name (and the default variant---optional )
EXCEPTIONS
not_found = 2.
The user can also choose from the list of existing variants using the function module REUSE_ALV_VARIANT_F4.
Step 3
DEFININING OUTPUT CHARACTERISTICS: PREPARING DISPLAY FIELDS CATALOG
A field catalog is prepared using the internal table (I_FIELDCAT) of type SLIS_T_FIELDCAT_ALV. Field catalog containing descriptions of the list output fields (usually a subset of the internal output table fields).
A field catalog is required for every ALV list output to add desired functionality (i.e. Key, Hotspot, Specific headings, Justify, Col. position etc) to certain fields of the output. If not mentioned specifically, then the defaults are taken. The possible values and defaults are listed below.
The field catalog for the output table is built-up in the caller's coding. The build-up can be completely or partially automated by calling the REUSE_ALV_FIELDCATALOG_MERGE module.
The minimal field catalog is documented below. This can be done in a routine using a local variable. The user can use the other optional parameters to assign output attributes to different fields in the output, which differ from the default.
A field catalog need not be built-up and passed explicitly only under the following conditions:
1. The internal table to be output has the same structure as a Data Dictionary structure which is referred to in the internal table declaration using LIKE or INCLUDE STRUCTURE. In this case the attributes of the different fields is taken directly from the table and the attributes (key fields, length, texts etc) need to state explicitly.
2. all fields in this structure are to be output
3. The structure name is passed to ALV in the parameter I_STRUCTURE_NAME of the function module REUSE_ALV_LIST_DISPLAY.
All the values entered in the catalog is specific to the particular field whose name is entered in the fieldname FIELDNAME of the fieldcat structure. The name of the table is also entered in the corr. Fieldname TABNAME of the structure.
The different possible attributes are:
Row_pos (row position): Only relevant if the list output is to be multi-line (two or three lines) by default. So, this attribute can be used maintain certain level of alignment in the output.
Value set: 0, 1 3
Col_pos (column position): This parameter is relevant when the fields in the output are to be different from the sequence of the fields in the internal table used for display. The parameter specifies the relative column position of the field in the list output. The column order can be changed interactively by the user. If this parameter is initial for all field catalog entries, columns appear in the internal table field sequence.
Value set: 0, 1 60
Fieldname (field name): This is the name of the internal table field for which the parameters are passed in the catalog.
Value set: internal output table field name (required parameter)
Tabname (internal output table): Name of the internal output table that contains the field FIELDCAT-FIELDNAME above.
Value set: SPACE, internal output table name.
Ref_fieldname (reference field name): Name of the Data Dictionary field referred to. This parameter is only used when the internal output table field described by the current field catalog entry has a reference to the Data Dictionary (not a program field), and the field name in the internal output table is different from the name of the field in the Data Dictionary. If the field names are identical, naming the Data Dictionary structure or table in the FIELDCAT-REF_TABNAME parameter is sufficient.
Value set: SPACE, Data Dictionary field name.
Ref_tabname (reference table/structure field name): Structure or table name of the referred Data Dictionary field. This parameter is only used when the internal output table field described by the current field catalog entry has a Data Dictionary reference (not a program field).
Value set: SPACE, name of a Data Dictionary structure or table
Link to currency unit
Cfieldname (currency unit field name): This is used for currency fields that have a reference to any unit field. This is only relevant for amount columns with associated unit. This parameter contains the Name of the internal output table field containing the currency unit associated with the amount field FIELDCAT-FIELDNAME. The field in FIELDCAT-CFIELDNAME must have its own field catalog entry.
Value set: SPACE, output table field name
Ctabname (internal currency unit field output table): Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
Value set: SPACE, output table field name.
Link to measurement unit
Qfieldname (measurement unit field name): Only relevant for quantity columns with unit link. Name of the internal output table field containing the measurement unit associated with the quantity field FIELDCAT-FIELDNAME. The field in FIELDCAT-QFIELDNAME must have its own field catalog entry.
Value set: SPACE, output table field name.
Qtabname (internal measurement unit field output table): Name of the internal output table containing the FIELDCAT-QFIELDNAME field.
Value set: SPACE, output table field name.
Outputlen (column width): This parameter is used if the desired output length for a field is desired to be different from the internal output table field. For fields with a Data Dictionary link this parameter can be left initial. For fields without a Data Dictionary link (program field) the parameter must be given the value of the desired field list output length (column width).
Initial = column width is the output length of the referred Data Dictionary field (domain).
N = column width is n characters.
Value set: 0 (initial), n.
Key (key column): By default, the system makes some fields in the output as key fields, provided the fields are key fields in their referencing table. Using this parameter, fields other than key fields of the referencing table can be made key field. This parameter is most important if the output needs to contain some field which are not scrollable or cannot be hidden.
If the internal output table contains fields that are key fields from different tables, then all those fields in the report output becomes unscrollable and cannot be hidden. So, the fields in the output internal table should not be referenced from tables in which they are key fields. Instead, they should be referenced to the tables in which they are not key fields, incase they are not desired as key field in the output.
'X' = key field (key field output in color) and Key fields can not be interactively hidden. Parameter FIELDCAT-NO_OUT must be left initial.
Value set: SPACE, 'X'.
Key_sel (hideable key column): This parameter is only relevant for the fields which are made key fields using FIELDCAT-KEY = 'X'. Using this parameter the Key field can be hidden interactively.
The key column sequence cannot be changed interactively by the user. The output is controlled by the FIELDCAT-NO_OUT parameter analogously to non-key fields.
Value set: SPACE, 'X'.
No_out (field in field list): This parameter is used to remove certain fields from the output during initial display. The user can however interactively choose the field for output from the field list in the display variant.
'X' = field is not displayed in the current list.
Value set: SPACE, 'X'.
Tech (technical field): This parameter is used to make certain field display only in the field catalog. The fields with this parameter set cannot be output in the list nor can they be displayed interactively from the catalog.
'X' = technical field.
Value set: SPACE, 'X'.
Emphasize (highlight columns in color): As name suggests, this field parameter is used to highlight certain field with chosen colors.
Value set: SPACE, 'X' or 'Cxyz' (x:'1'-'9'; y,z: '0'=off ,'1'=on).
'X' = column is colored with the default column highlight color.
'Cxyz' = column is colored with a coded color:
- C: Color (coding must begin with C)
- X: color number
- Y: bold
- Z: inverse
Hotspot (column as hotspot): This parameter is used to make certain field appear as hotspot i.e. a hand is displayed if the cursor is positioned on the field value. Single click on such fields cause the PICK OR F2 events to happen.
Value set: SPACE, 'X'.
'X' = column cells are output as hotspots.
Fix_column (fix column): This parameter is used to fix certain columns in the output. All columns to be fixed must have this flag, starting from the left. If a column without this flag is output, only the columns to the left of this column are fixed. The user can change the column fixing interactively.
Value set: SPACE, 'X'.
'X' = column fixed (does not scroll horizontally).
Do_sum (sum over column): the user can also call this function interactively.
Value set: SPACE, 'X'.
'X' = a sum is calculated over this internal output table field.
No_sum (sums forbidden): No sum can be calculated over this field, although the data type of the field would allow summing.
Value set: SPACE, 'X'.
Icon: The parameter displays certain column contents as icons. The internal output table column contents must be valid icon strings.
Value set: SPACE, 'X'.
'X' = column contents to be output as an icon.
Symbol: The internal output table column must be a valid symbol character.
Value set: SPACE, 'X'
'X' = column contents are to be output as a symbol.
Just (justification): This parameter is used for alignment of the contents of the output table. This is only relevant for CHAR or NUMC fields in the output internal table. The justification of the column header always follows the justification of the columns. Independent justification of the column header is not possible.
Value set: SPACE, 'R', 'L', and C.
' ' = Default justification for this data type
'R' = right-justified output
'L' = left-justified output
'C' = centered output.
Lzero (leading zeros): By default ALV outputs NUMC fields right-justified without leading zeros. Using this parameter only the NUMC fields can be displayed with leading zeroes.
Value set: SPACE, 'X'.
'X' = output with leading zeros.
No_sign (no +/- sign): This parameter is used to suppress the signs of the output fields. It is only relevant for the value fields.
Value set: SPACE, 'X'.
'X' = value output without +/ sign.
No_zero (suppress zeros): Only relevant for value fields.
Value set: SPACE, 'X'.
'X' = suppress zeros.
Edit_mask (field formatting): To apply the report output formatting options same as in the WRITE statement in report writing.
Value set: SPACE, template.
The following parameters are used for customizing the texts in the heading of the output of the columns. The texts are taken from the Data Dictionary for fields with a Data Dictionary reference. If this is not desired, the text parameters can also be specified. The Data Dictionary texts are then ignored.
If the user changes the column width interactively, the column header text with the appropriate length is always used.
The interactive function 'Optimize column width' takes account of both the field contents and the column headers: if all field contents are shorter than the shortest column header, the column width depends on the column header.
The 'long field label' is also used in display variant definition,
Sort, etc. Popup.
seltext_l (long field label)
seltext_m (medium field label)
seltext_s (short field label)
reptext_ddic(header) Analogous to the Data element main header
Ddictxt (specify text) : You can specify with values 'L', 'M', and 'S', the keyword that should always be used as column header. If the column width changes, no attempt is made in this case to find an appropriate header for the new output width.
Value set: SPACE, 'L', 'M', and S.
Sample code:
Suppose I_PO_DETAILS is an internal table containing two fields EBELN (PO number) and EBELP (PO item no).
DATA: L_FIELDCAT TYPE SLIS_FIELDCAT_ALV. Local variable to hold the parameters
for a particular field of the field catalog
CLEAR L_FIELDCAT.
L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
L_FIELDCAT-FIELDNAME = 'EBELN'.
L_FIELDCAT-KEY = 'X'. The PO no is made the key field,
Colored and non scrollable
L_FIELDCAT-HOTSPOT = 'X'. The po no becomes a hotspot
L_FIELDCAT-SELTEXT_S = P.O No.
L_FIELDCAT-SELTEXT_M = 'P order No'.
L_FIELDCAT-SELTEXT_L = 'Purchase order No'.
APPEND L_FIELDCAT TO I_FIELDTAB.
CLEAR L_FIELDCAT
L_FIELDCAT-TABNAME = 'I_PO_DETAILS'.
L_FIELDCAT-FIELDNAME = 'EBELN'.
L_FIELDCAT-KEY = 'X'. The po item no is made the key field,
Colored and non scrollable
L_FIELDCAT-SELTEXT_S = 'Item No'.
L_FIELDCAT-SELTEXT_M = 'Item No`.
L_FIELDCAT-SELTEXT_L = 'PO Item No'.
APPEND L_FIELDCAT TO I_FIELDTAB.
CLEAR L_FIELDCAT
Thus the catalog for the report output is prepared.
Step 4
The next step is to build an event table, which are used for firing both user commands and the system dependent events i.e. top of page, end of page etc.
A list of possible events is populated into an event table (I_EVENTS) when this table is passed to the function module REUSE_ALV_EVENT_NAMES_GET. The return table from this function module contains all the possible events.
The function module contains following import and export parameters.
IMPORTING PARAMETERS: I_LIST_TYPE
This parameter has possible values from 0-4.
The parameter I_LIST_TYPE is of TYPE SLIS_LIST_TYPE and is DEFAULT 0 .
EXPORTING PARAMETERS: I_EVENTS table.
This table is of TYPE SLIS_T_EVENT and returns to the program the name of all the possible events.
The table structure contains the fields:
I_EVENTS-NAME: Name of the Callback event.
I_EVENTS-FORM: Name of the form routine that should be called in the calling program at the event.
Only events with a form routine name are processed.
The I_EVENTS table returns with the following possible constants:
1. Slis_ev_item_data_expand TYPE slis_formname VALUE 'ITEM_DATA_EXPAND'.
Only relevant for hierarchical-sequential lists using the layout parameter IS_LAYOUT-EXPAND_FIELDNAME of the structure IS_LAYOUT. Exit for passing item entries (ITEM table) for a header record that was expanded interactively by the user.
2. Slis_ev_reprep_sel_modify TYPE slis_formname VALUE 'REPREP_SEL_MODIFY'.
RS_SELFIELD-TABINDEX contains the header table index for which the item entries are to be put in the global item output table (T_OUTTAB_SLAVE). The Callback is only called if ALV has no items for a header that is to be expanded.
RFLG_ALL is passed with 'X' if the user shows all items. The application must ensure that entries are not repeated in the item table.
RS_SELFIELD is initial in this case.
3. Slis_ev_caller_exit_at_start TYPE slis_formname VALUE 'CALLER_EXIT'.
Is called at the beginning of the function module to make special settings. It is not usually used.
4. Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface by passing the user command in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
5. Slis_ev_top_of_page TYPE slis_formname VALUE 'TOP_OF_PAGE'.
Equivalent to the list processing TOP-OF-PAGE event.
6. Slis_ev_top_of_coverpage TYPE slis_formname VALUE 'TOP_OF_COVERPAGE'.
The selection information and list status are output together (if they exist) on a separate page by default
7. Slis_ev_end_of_coverpage TYPE slis_formname VALUE 'END_OF_COVERPAGE'.
Analogously to TOP_OF_COVERPAGE the user can add other information
to the information output by ALV (selection information, list status) at this event.
8. Slis_ev_foreign_top_of_page TYPE slis_formname VALUE FOREIGN_TOP_OF_PAGE'.
The Top-of-page event is always processed in ALV and is only passed to the caller via the Callback mechanism. This is still the case if the caller, e.g. by a user action, processes a branch list which was not formatted by ALV (e.g. a popup with additional information about the list record selected and displayed by ALV).
In this case, top-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event top-of-page still occurs in ALV. When ALV notices a top-of-page which was not caused by an ALV output, the form routine in FOREIGN_TOP_OF_PAGE is called.
9. Slis_ev_foreign_end_of_page TYPE slis_formname VALUE 'FOREIGN_END_OF_PAGE'.
The event end-of-page is always processed in ALV and only passed to the caller via callback. This is still the case, e.g. when the caller processes a details list which was not formatted by ALV (e.g. a popup with further information about selected list records which were displayed by ALV).
In this case, end-of-page cannot be formatted by ALV analogously to the basic list, it must be handled completely by the caller. The event end-of-page still occurs in ALV. When ALV notices an end-of-page that was not caused by an ALV output, the form routine in FOREIGN_END_OF_PAGE is called.
10. Slis_ev_pf_status_set TYPE slis_formname VALUE 'PF_STATUS_SET'.
If a user list status is to be set, it must be done in the form routine assigned to this event. The ALV function codes, which must not be active, are in the Parameter RT_EXTAB. This table must be passed with the SET PF-STATUS command (with inactive user function codes as well, if necessary).
The STANDARD status of the function group SALV should be used as a template for a user-specific status. As this is a frequently used Callback event, its form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_PF_STATUS_SET.
11. Slis_ev_list_modify TYPE slis_formname VALUE 'LIST_MODIFY'.
LIST_MODIFY USING R_TABNAME TYPE SLIS_TABNAME
R_INDEX LIKE SY-TABIX
R_INDEX_ITEM LIKE SY-TABIX
R_INDEX_SUM LIKE SY-TABIX.
12. Slis_ev_top_of_list TYPE slis_formname VALUE 'TOP_OF_LIST'.
Information output at the start of the list
13. Slis_ev_end_of_page TYPE slis_formname VALUE 'END_OF_PAGE'.
Information output at the end of a page. This is only called for printing.
14. Slis_ev_end_of_list TYPE slis_formname VALUE 'END_OF_LIST'.
Information output at the end of the list
15. Slis_ev_after_line_output TYPE slis_formname VALUE 'AFTER_LINE_OUTPUT'.
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
16. Slis_ev_before_line_output TYPE slis_formname VALUE 'BEFORE_LINE_OUTPUT'.
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
17. Slis_ev_subtotal_text TYPE slis_formname VALUE 'SUBTOTAL_TEXT'.
This event table (I_EVENTS) is now checked with the desired constants. If the desired constant is found, then the corresponding field for the FORM NAME is populated with the name of the routine containing the corresponding event.
Sample code :
FORMNAME_TOP_OF_PAGE TYPE SLIS_FORMNAME VALUE 'TOP_OF_PAGE',
FORMNAME_END_OF_PAGE TYPE SLIS_FORMNAME VALUE 'END_OF_PAGE', FORMNAME_USER_COMMAND TYPE SLIS_FORMNAME VALUE 'USER_COMMAND'.
DATA: L_I_EVENT TYPE SLIS_ALV_EVENT.
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
EXPORTING
I_LIST_TYPE = 0
IMPORTING
ET_EVENTS = I_EVENTS.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_TOP_OF_PAGE
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_TOP_OF_PAGE TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_END_OF_PAGE
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_END_OF_PAGE TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
CLEAR L_I_EVENT.
READ TABLE I_EVENTS WITH KEY NAME = SLIS_EV_USER_COMMAND
INTO L_I_EVENT.
IF SY-SUBRC = 0.
MOVE FORMNAME_USER_COMMAND TO L_I_EVENT-FORM.
APPEND L_I_EVENT TO I_EVENTS.
ENDIF.
This will prepare the events table for the report.
The report will contain three forms for the above events:
1. FORM TOP_OF_PAGE : This form will contain the top of page event for the report i.e header etc
Using the function module REUSE_ALV_COMMENTARY_WRITE, the internal table containing the headings for top of page event can be passed to the list output. Also, any logo specific to the report can be passed to the function module.
2. FORM END_OF_PAGE : This form will contain the end of page event for the report i.e footer etc
3. FORM USER_COMMAND : This form will contain the desired user command i.e pick/line selection
Step 5
A layout is build for the report output list description USING the internal table declared above (I_LAYOUT).
Output list description structure.
The parameters are described under the following heads:
Display options
Exceptions
Totals

39. No_scrolling(1) TYPE c : Does not allow scrolling of the list to the right.
Value set: SPACE, 'X'.
40. Expand_all(1) TYPE c : Expand all positions
Detailed screen
40. Detail_popup(1) TYPE c : show detail in popup.
Value set: SPACE, 'X'
' ' = List record detail display in full-screen mode, with top-of-page.
'X' = list record detail display in popup (without top-of-page).
41. Detail_initial_lines(1) TYPE c : show also initial lines
Value set: SPACE, 'X'
' ' = Only fields whose contents are not initial are output in the detail view.
'X' = initial field contents are also output in detail.
41. detail_titlebar(30) type c : Titlebar for detail screen
Value set: SPACE, string (max.30)
` ' = ' Detail: Display' is output as the title of the detail window.
'String = the string passed is output as the title of the detail window.
Display variants
42. Header_text (20) TYPE c: Text for header button. Only relevant for hierarchical-sequential lists. You can toggle between display field and field list views via pushbuttons in the display variant definition popup for hierarchical-sequential lists. The views refer to the hierarchy level of the fields. This is technically a toggle between the header table and item table fields.
Value set: SPACE, CHAR (20)
' ' = The header table field pushbutton text is 'Header' by default.
CHAR (20) = header table field pushbutton text.
43.item_text(20) TYPE c : Text for item button. Only relevant for hierarchical-sequential lists. You can toggle the view between the display fields and the field list via pushbuttons in the display variant definition popup for hierarchical-sequential lists. The views refer to the hierarchy level of the fields. This is technically a toggle between the header table and item table fields.
Value set: SPACE, CHAR (20)
' ' = The pushbutton text for the item table fields is 'Item' by default.
CHAR (20) = item table field pushbutton text.
44.default_ item(1) TYPE c : Items as default. Only relevant for hierarchical-sequential lists.
Value set: SPACE, 'X'
' ' = The header table fields are displayed by default in the display variant definition popup. The user can switch to the item table fields interactively.
'X' = the item table fields are displayed by default in the display variant Definition Popup. The user can switch to the header table fields interactively.
Colour
45. Info_fieldname TYPE slis_fieldname: infofield for listoutput. A whole list record can be colored individually using a color code in a column of the internal output table for the record. Assign the name of the field containing the color code to this parameter.
Value set: SPACE, internal output table field name
The internal output table field must be of type CHAR(3).
The code must have the following syntax: 'Cxy':
C = color (all codes must start with 'C')
X = color number ('1'-'9')
Y = bold ('0' = off, '1' = on)
46. Coltab_fieldname TYPE slis_fieldname: Cells can be colored individually using a color code which is contained in a column of the internal output table for the record containing the cell. Assign the name of the field to this parameter.
Others
47. List_append(1) TYPE c : no call screen. It is only useful to output block-lists without specifying the above modules if the number of list blocks exceeds, or may exceed, the maximum number specified in the block module documentation. These operations are not possible for user-defined block lists.
Example code :
I_LAYOUT-f2code = ws_fcode.
I_LAYOUT-zebra = 'X'.
I_LAYOUT-colwidth_optimize = 'X'.
I_LAYOUT-no_keyfix = 'X'.
I_LAYOUT-get_selinfos = 'X'.
I_LAYOUT-no_hotspot = 'X'.
I_LAYOUT-no_input = 'X'.
I_LAYOUT-hotspot_fieldname = FIELDNAME.
I_LAYOUT-no_input = X.
I_LAYOUT-no_vline = `X.
I_LAYOUT-no_colhead = .
I_LAYOUT-lights_condense = ` `.
I_LAYOUT-totals_text = ` `.
I_LAYOUT-subtotals_text = ` `.
I_LAYOUT-totals_only = ` `.
I_LAYOUT-key_hotspot = X.
I_LAYOUT-detail_popup = X.
I_LAYOUT-group_change_edit = X.
I_LAYOUT-GROUP_BUTTONS = X.
Step 6
This step is required to get the selection screen information in the report output.
The prerequisite for this is to set the parameter LAYOUT-GET_SELINFOS of the IMPORTING structure.
The parameters to be passed in the IS_SEL_HIDE table are:
o mode: 'R' = only the entries passed in the internal table IS_SEL_HIDE-T_ENTRIES
Are output in the pop up. Selection info, which the list tool read in the selection screen (when called by a report with a selection screen), is replaced by the values passed.
'S' = the selection info which the list tool read in the selection screen of the calling report are modified by the entries in the table IS_SEL_HIDE-T_ENTRIES.
o t_entries: Selection info table
o t_entries-mode: 'A' = output the selection info for the current table record in the info popup.
'D' = do not output select option or SELNAME parameter selection info in the popup.
o t_entries-selname: (only used in t_entries-mode = 'D') : Name of the select option or parameter.
The following table fields are only used in t_entries-mode = 'A'. They contain the selection information to be added.
t_entries-field: DDIC field name of the field for which selection information is to be output.
t_entries-table: DDIC table names of t_entries-field.
t_entries-stext: Field name in info popup.
If t_entries-field and t_entries-table have been entered, this text is taken from DDIC.
t_entries-valuf: Selection condition 'from' value (external format)
t_entries-valut: Selection condition 'to' value (external format)
t_entries-sign0: (I)nclusive (E)xclusive
t_entries-option: All values of the select options Option field allowed.
Step 6
The Table IT_SORT is populated with the sort criteria for the different fields.
The caller specifies the sorting and/or subtotaling of the basic list in the internal table IT_SORT.
This internal table has the following fields:
o spos : Sort sequence
o fieldname : Internal output table field name
o tabname : Only relevant for hierarchical-sequential lists. Name of the internal output table.
o up : 'X' = sort in ascending order
o down : 'X' = sort in descending order
o subtot : 'X' = subtotal at group value change
o group : '* ' = new page at group value change ,'UL' = underline at group value change
Step 7
The final step in the output of the report is the use of two ALV functions modules.
1. REUSE_ALV_FIELDCATALOG_MERGE
2. REUSE_ALV_LIST_DISPLAY
The first function module is used to pass the field catalog to the report output and merge it with the internal output table.
FUNCTION reuse_alv_fieldcatalog_merge.

Increase edit length in ALV GRID
Hi All,
I am using wa_fieldcat-edit for editing the ALV outreport.
But here by editing i am able to enter only 10 characters in that filed.
How can i increase this length upto 40 characters.
Please help me in this.
Regard,
Kalyan VarmaHi Kalyan.
You can make any field of your alv editable by passing "X'in the edit parameter of the field catalog.Once you have made the field editable you can change its value.By deafult the width of that field with be equal to the size of the field of the internal table through which you are displaying the data in alv.If u want to increase or decrease the width by using the outputlen parameter of the field catalog as i have mentioned in my earlier post.
I tried it on my code.Initially the matnr was of length 18 but i increased it length to 40.The code is as follows:
DATA : OUT_LEN LIKE dd03p-outputlen VALUE '40'.
DATA : I_FCAT TYPE SLIS_T_FIELDCAT_ALV,
wa_fcat TYPE SLIS_FIELDCAT_ALV.
DATA : C_CHECK TYPE C VALUE 'X'.
LOOP AT I_FCAT INTO WA_FCAT.
if ( wa_fcat-fieldname = 'MATNR' ).
WA_FCAT-HOTSPOT = C_CHECK.
WA_FCAT-EDIT = C_CHECK.
WA_FCAT-outputlen = OUT_LEN.
ENDIF.
MODIFY i_fcat FROM wa_fcat TRANSPORTING edit OUTPUTLEN.
ENDLOOP.
In the end you have to pass the i_fact(field catalog) to the IT_FIELDCAT parameter of REUSE_ALV_GRID_DISPLAY like this.
IT_FIELDCAT = i_fcat
I think you would be able to solve it now.
Thanks!! -
Need to display Long Text as field Name in ALV
Hi,
I am using an ALV Grid Display. Even though i have kept the output field length to be 30 char, the Column header that is being selected is the short name. I would like the Column header to display the long name.
For example: Field "MAKTX"
l_seltext_l = "Description"
L_seltext_s = "Descr"
I want to display "Description" as the field name but it is displaying the short length even though the field is 30 characters wide.
Please help.
Thanks,
UrmilaHi,
along with <b>fieldcat-SELTEXT_L = 'long text'.</b>
try to pass this also..
<b>fieldcat-DDICTXT = 'L'.</b>
so this will allow only long text.
Regards

Hi,
I have pulled up the required e-mail field from table ADR6 , but the problem is the ADR6-SMTP_ADDR field length is 241 char which is taking too much space in the ALV output may i know how to reduce the actual legnth of field to the required pls..
Thxs,
Vin.Hi,
if you are using 'REUSE_ALV_FIELDCATALOG_MERGE' to build the field catelog, then change the field length with below code :
loop at it_fieldcat into x_fieldcat.
if x_fieldcat-fieldname = 'SMTP_ADDR'.
x_fieldcat-OUTPUTLEN = 20.
modify it_fieldcat from x_fieldcat index sy-tabix.
endif.
endloop.
if you are building the fieldcatelog in your own way then use below code to change the field length.
it_fieldcat-FIELDNAME = 'SMTP_ADDR'.
it_fieldcat-KEY = 'X'.
it_fieldcat-OUTPUTLEN = '20'.
it_fieldcat-SELTEXT_L = 'E-Mail'.
APPEND it_fieldcat .
CLEAR it_fieldcat .
