PUSH BUTTON IN FIELD CATALOG - NEED HELP

Hi all,
I have a requirement wherein i need to have a push button in the first column of ALV GRID DISPLAY output to be able to select multiple rows. Now am using SELKZ field in field catalog, though it creats a first column, the push button is not available. Is there any field in FIELD CATALOG other than this field which will satisfy my requirement or any other possible way to achieve this functionality.
PERFORM alv_fieldcat USING :
      't_output' 'SELKZ' ' ' ' ',
In form, i've written the following piece of code.
l_fieldcat-tabname      = tabname.
l_fieldcat-fieldname    = fieldname.
l_fieldcat-reptext_ddic = coltext.
l_fieldcat-hotspot      = hotspot.
Any input in this regard will be valuable to me and highly appreciated.
Thanks in advance,
Vaishnavi Varadarajan

PMW CTX format record 6 field 7 - need help mapping it

We went live in 2007 on ERP6.0 and used the Payment Medium Workbench for our ACH payments. The person who did the original config has left and I now need assistance to fix an issue. We were told at go live that our field FPAYH/BKREF should be mapped to our NACHA record 6 field 7 (the Identification Number field). Recently we discovered that the field has been blank since our go live. As I look at the ACH US Domestic payment transactions USA config. I can see the 00, 05, 20, 30, and 40 Events activated. It appears the Event 30 - Order/transaction record may control the mapping I am needing to correct.
How do I go about correcting the field (without modifying the SAP code directly?). We can see in the ABAP code that the field 7 just has a SPACE in it instead of the FPAYH/BKREF field. Could someone provide the step by step of what I need to do? Do I need to create a new event 31, make changes there and if so how do I activate the new event?? Or is there a place in config that I should be seeing that I can just change the SPACE to the appropriate field??
Please advise!!

Hi Cindy,
check the user exits in program RFFOEXIT. A technical guy should be able to help you out on this. Exit 100 - 120 is for USA.
Hope this helps.

This is most often due to screen resolution settings. Make sure you are set to at least 1024x768

Linking flash buttons? not working need help:)

Hey guys,
Got a site here - www.fatalwisdom.com - as you can see i want
the top swf file - with the links in there to work like eg. audio
button when clicked going to; audio.htm.
The file won't seem to work though - here is the file :
www.mastacraft.com/fatalwisdom/top1.fla .
Thanks to anyone who can help.
Regards, Patrick

to use a button you need to use:
on (release) {
getURL(www.mastacraft.com/fatalwisdom/audio.htm);
so the getURL ws good but for a button you need to use the on
(release) {
}

Play button AS2 not working need help please!

Hi,
I have an AS2 project with two scenes, Scene 1 is has a pre-loader and Scene 2 has an embedded .flv animation from after effects with some other basic tweened shape layers and masks. I've used the Components UI and dragged a "Replay" button to the last keyframe with a seperate actions layer with the following code:
stop();
Replay.addEventListener(MouseEvent.CLICK, replayMovie);
function replayMovie(evt)
gotoAndPlay("Scene 2",1);
I'm a beginner in Flash and have been following instructions off the net but I can't get it to Replay the movie when the button is clicked, it does nothing
any help will be appreciated.

Hi,
I would not reply on the scene naming thingy if I were you. IN the pat I have had the very same problem and found that using
_root.gotoAndPlay(frameNumberHere); works a lot better.
ALSO
if your scene 1 has 10 frames in it and your want to gotoAndPLat the 1st frame of your second scene then use:
var number_of_Frames_in_1st_scene = 10
var frame_I_want_to_go_to_and_play_in_my_second_scene_is = 1
var frameNumber = number_of_Frames_in_1st_scene + frame_I_want_to_go_to_and_play_in_my_second_scene_is;
_root.gotoAndPlay(frameNumber);
dont forget the _root.

LR2 Experienced System Crash & Corrupted Catalog - Need Help!!!

We are using: Mac OS X Version 10.5.8
Background on Lightroom Use:
The size of the catalog in question is 296 MB.
Pictures on an 8GB smart card were being uploaded into lightroom and simultaneously moved into a folder on an external hard drive at the time of the crash. (During this download, the imac screen gave us a very scary...."Death Veil" that started at the top and slowly covered in a downward motion the entire screen, freezing up the computer completely.)
The error message said we needed to restart the computer using the restart option or shut the computer down using the on/off switch.
Since the computer was "frozen" we were unable to access the restart option so we hit the off switch, holding it down until the imac shut itself down.
After waiting for approximately a minute, we restarted the imac.
The imac started as it usually does, however, when we opened Lightroom2, the following message appeared:
After Selecting the "Repair Catalog" Option the following message appeared:
Other catalogs are operating properly in LIghtroom.
We have no available backup and are looking for someone who can assist with
perhaps fixing the corrupted catalog. (Literally, thousands of hours)

If you ever ran "Save" on a lot of images, you'll have all your edits and metadata for those images, and if you ran save recently on the whole catalog of images, you'll be pretty well off. In such a case, I'd start a brand new catalog, and Import in place all the images.
However, assuming the worst, that the above avenue won't yield much, one particular Adobe employee, Dan Tull, is a whiz at repairing catalogs, and you may get it done by sending the catalog to him. From a post long ago: Dan Tull can be contacted at dtull-at-adobe.com .. .. note that @ has been substitued with -at- in above email address .. I haven't seen Dan in this forum for a while, so it's not a for sure thing.

The above code is not working. Any idea?
Please help me out!

Read the application server logs. My cents on an IllegalStateException.
To solve this, properly separate the business and controller logic from the presentation logic. Use a Servlet. Right now you're doing some business and controller logic while the presentation logic already has been run. This is asking for problems.
Not related to the problem, but you should also separate the data logic as well.

Field Catalogs in ALV

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'.

    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).

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.

The variant based on a program-internal table should only be used for rapid prototyping since the following restrictions apply:
1.   Performance is affected since the code of the table definition must always be read and interpreted at runtime.
2.   Dictionary reference are only considered if the keywords LIKE or INCLUDE STRUCTURE (not TYPE) are used.

What is Field catalog pls urgent

Right now I am working on ALV, in that I am using REUSE_ALV_GRID_DISPLAY FM, but the parameters for this FM are an internal table name and a field catalog so i am confused that what field catalog is? Please help me out its very urgent. Thanks in advance.

Hi,
<b>Field catalog</b>
The field catalog describes the internal data table fields. It is itself an internal table containing an entry for each column in the data table. The field catalog entry determines column output options.
<b>Creating the field catalog</b>
The field catalog can be constructed in various ways:
<b>Manual</b>
Each field catalog entry is explicitly coded into the field catalog by the ALV caller.
Fields with DDIC link must have at least the following field catalog entries:
FIELDCAT-FIELDNAME          " Internal output table field name
FIELDCAT-REF_TABNAME          " DDIC reference structure name
Fields with no DDIC link must have at least the following field catalog entries:
FIELDCAT-FIELDNAME          " Internal output table field name
FIELDCAT-DATATYPE          " Internal output table field data type
FIELDCAT-OUTPUTLEN          " Column width
and at least one of the four text fields FIELDCAT-SELTEXT_L, FIELDCAT-SELTEXT_M, FIELDCAT-SELTEXT_S, REPTEXT_DDIC.
The field FIELDCAT-TABNAME in the field catalog of hierarchical-sequential lists must also contain the name of the internal output table, to assign columns uniquely to the header or item table. This field must not be filled manually in simple lists.
<b>Automatic</b>
A field catalog need not be passed to ALV under the following condition:
the structure of the internal output table is identical to a DDIC structure or table.
The name of the structure or table is passed to ALV instead of the field catalog.
All columns in the structure are displayed.
<b>Semi-automatic</b>
This mode is a combination of automatic and manual:
the automatically created field catalog can be modified by a manually created field catalog.
If a structure name for an automatic field catalog and a field catalog are both passed, the system determines the field catalog information from them both:
     If the manually created and passed field catalog contains entries for fields which are not described by the DDIC structure, they are added to the field catalog created by the System.
     If the manually created and passed field catalog contains entries for fields which are also described by the DDIC structure, they overwrite the DDIC information.
The system creates field catalogs automatically and semi-automatically from the DDIC reference structure passed to ALV. ALV calls the function module REUSE_ALV_FIELDCATALOG_MERGE which creates the field catalog and adjusts it with an explicit field catalog (semi-automatic mode). This function module can also be called directly by the application (before ALV). This makes the creation of the field catalog by the application flexible.
Hope u understood.
Kindly reward points if u find it useful.
Thanks&Regards,

and then after selecting different month from the list_item the values that ive retrieve will be filter according to the value in the list_item
it looks something like this:
stud_id = 1001
time_in
01-JAN-10
02-JAN-10
03-JAN-10
01-FEB-10
02-FEB-10
03-FEB-10
