Important function modules

Hi,
Can you tell me list of important Function modules used in ABAP or send me a doc please?
My email id: [email protected]
Thanks in advance.

Nuren,
Its all depends on what you need, you can get the list from se37 itself. Whenever you need to search, you can first use of searching with descrition by giving download .....
Similarly you can search in the same way for function groups and then the list of FM's under this FG.

GTS tables relations and important function modules

Hi Friends,
I am totally new for the developments in GTS. Wanted some help on the tables for master data, transactional data in GTS.
Also what are the important function modules used in GTS.
Anybody can give me some inputs on the above..?
regards
Nalin

Well, passing a table thru the interface with no type is easy, just don't assign a structure when defining the interface. It will then take its structure by what is being passed to it.
So if you would pass an internal table to it with the structure like so.
Data: begin of itab occurs 0,
      line(1000) type c,
      end of itab.
Then that is the structure inside the function module.
Did this answer your question?   Please explain further if not.

Rich Heilman

Function module used for formatting alv

hi gurus,
which function module is uesd to format alv?

Hi
see the following
ABAP List Viewer
The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).
This helps us to implement all the features mentioned very effectively.
Using ALV, We can have three types of reports:
1. Simple Report
2. Block Report
3. Hierarchical Sequential Report
There are some function modules which will enable to produce the above reports without much effort.
All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
1. SIMPLE REPORT.
The important function modules are
a. Reuse_alv_list_display
b. Reuse_alv_fieldcatalog_merge
c. Reuse_alv_events_get
d. Reuse_alv_commentary_write
e. Reuse_alv_grid_display
A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
The important parameters are :
I. Export :
i. I_callback_program : report id
ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status
iii. I_callback_user_command : routine where the function codes are handled
iv. I_structure name : name of the dictionary table
v. Is_layout : structure to set the layout of the report
vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE
vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
II. Tables :
i. t_outtab : internal table with the data to be output
B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table
iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events
for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action
Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.
2. BLOCK REPORT

Note : Fieldcatalog can be filled manually also by filling up all the required details into the internal table
The important parameters are:
 1. Export:
 a. I_program_name : report id
 b. I_internal_tabname : the internal output table
 c. I_inclname : include or the report name where all
 the dynamic forms are handled.

B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table
iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is
declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events
for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action
Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.

some theory regarding alv:
This table tells ALV which events are processed by the caller by CALLBACK.
The table of possible events per list type can be initialized using the module REUSE_ALV_EVENTS_GET.
You can display the names of the constants in the type pools SLIS which represent the individual events using the individual test function in the function module
REUSE_ALV_EVENT_NAMES_GET. Only events with a form routine name are processed.
The table structure contains the fields:
IT_EVENTS-NAME
Name of the Callback event.
Possible Callback events:
Action
USER_COMMAND USING R_UCOMM LIKE SY-UCOMM RS_SELFIELD TYPE SLIS_SELFIELD
Process actions on the list
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
PF_STATUS_SET USING RT_EXTAB TYPE SLIS_T_EXTAB
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.
ITEM_DATA_EXPAND USING RS_SELFIELD TYPE SLIS_SELFIELD RFLG_ALL TYPE C
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 which was expanded interactively by the user.
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 which 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.
CALLER_EXIT USING RS_DATA Is called at the beginning of the function module to make special settings. It is not usually used.
List processing events
IMPORTANT: The application Callback routine must not manipulate the internal output table and/or its header record. This restriction applies to all Callbacks which are called in the list output and run under the 'List processing events'.
TOP_OF_LIST no USING parameter. Information output at the start of the list
END_OF_LIST no USING parameter. Information output at the end of the list
TOP_OF_PAGE no USING parameter
Equivalent to the list processing TOP-OF-PAGE event
END_OF_PAGE no USING parameter. Not available for hierarchical-sequential lists.
Information output at the end of a page. This is only called for printing.
TOP_OF_COVERPAGE no USING parameter
The selection information and list status are output together (if they exist) on a separate page by default. See also the documentation of the parameters:
IS_PRINT-NO_COVERPAGE
IS_PRINT-NO_PRINT_SELINFOS
IS_PRINT-NO_PRINT_LISTINFOS
IS_LAYOUT-GET_SELINFOS
The user can format the header area of the 'cover page' himself or herself by specifying a Callback routine for this event.
END_OF_COVERPAGE no USING parameter
Analogously to TOP_OF_COVERPAGE the user can add other information to the information output by ALV (selection information, list status) at this event.
FOREIGN_TOP_OF_PAGE no USING parameter
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.
FOREIGN_END_OF_PAGE no USING parameter
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.
BEFORE_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information before each output line. Should only be used in justified cases because it costs a lot of performance.
AFTER_LINE_OUTPUT USING RS_LINEINFO TYPE SLIS_LINEINFO
Output information after each output line. Should only be used in justified cases because it costs a lot of performance.
Internal use only
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
IT_EVENTS-FORM
Name of the form routine which should be called in the calling program at the event.
Field_catalog:
Field catalog with field descriptions
2.7.1. Description
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.
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
See also the documentation of the function module REUSE_ALV_FIELDCATALOG_MERGE.
The minimal field catalog is documented under 'default'. The caller can use the other optional parameters to assign output attributes to a field which differ from the default.
A field catalog need not be built-up and passed explicitly only under the following conditions:
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.
all fields in this structure are to be output
the structure name is passed to ALV in the parameter I_STRUCTURE_NAME.
See also the documentation of the IMPORTING paramter I_STRUCTURE_NAME.
Positioning
row_pos (row position)
value set: 0, 1 - 3
Only relevant if the list output is to be multi-line (two or three lines) by default.
A multi-line list can also be defined by the user interactively if the default list is one-line.
The parameter specifies the relative output line of the column in a multi-line list.
col_pos (column position)
value set: 0, 1 - 60
only relevant when the default relative column positions differ from the field catalog field sequence. 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 field catalog field sequence.
Identification
fieldname (field name)
value set: internal output table field name (required parameter)
Name of the internal output table field which is described by this field catalog entry
tabname (internal output table)
value set: SPACE, internal output table name
This parameter is used in 'manual' field catalog build-up only for hierarchical-sequential lists.
Name of the internal output table which contains the field FIELDCAT-FIELDNAME.
Data Dictionary reference
ref_fieldname (reference field name)
value set: SPACE, Data Dictionary 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.
ref_tabname (reference table/structure field name)
value set: SPACE, name of a Data Dictionary structure or table
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).
Reference to fields with currency/measurement unit
Each internal output table sum or quantity field whose decimal places are to be formatted appropriately for the unit in the list must follow the convention:
the field is of data type QUAN or CURR (internal type P) (the field must really have this physical data type. Overwriting the physical data type with the parameter FIELDCAT-DATATYPE has no effect)
There is a field in the internal output table which contains the associated unit.
There is also an entry in the field catalog for the unit field.
(If the unit is not to appear as a column in the list, and cannot be interactively displayed as a column, e.g. because it is always unambiguous and is therefore explicitly output by the caller in the list header, the field catalog units field entry can take the parameter FIELDCAT-TECH = 'X'.
The association of a value field to a unit affects the output as follows:
appropriate decimal places display for the unit
an initialized field with a link to a non-initial unit is output as '0' for the unit (if FIELDCAT-NO_ZERO is initial). When this field is summed, this unit affects whether the units are homogeneous.
an initialized field with a link to an initial unit is output as SPACE. When this field is summed, the unit SPACE does not affect the homogeneity of the units.
When non-initial fields with an initial unit are summed, the unit SPACE is considered to be a unit.
Link to currency unit
cfieldname (currency unit field name)
value set: SPACE, output table field name
Only relevant for amount columns with associated unit.
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.
ctabname (internal currency unit field output table)
value set: SPACE, output table field name
only relevant for hierarchical-sequential lists
Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
Link to measurement unit
qfieldname (measurement unit field name)
value set: SPACE, output table 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.
qtabname (internal measurement unit field output table)
value set: SPACE, output table field name
only relevant for hierarchical-sequential lists
Name of the internal output table containing the FIELDCAT-QFIELDNAME field.
Column output options
outputlen (column width)
value set: 0 (initial), n
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
key (key column)
value set: SPACE, 'X' 'X' = kex field (key field output in color)
Key fields can not be interactively hidden. Parameter FIELDCAT-NO_OUT must be left initial.
For exceptions see the documentation of the FIELDCAT-KEY_SEL parameter.
key_sel (hideable key column)
value set: SPACE, 'X'
only relevant when FIELDCAT-KEY = 'X'
Key field which 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.
no_out (field in field list)
value set: SPACE, 'X' 'X' = field is not displayed in the current list.
The user can interactively choose the field for output from the field list.
The user can display the contents of these fields at line level using the 'Detail' function.
See also the 'Detail screen' documentation of the parameter IS_LAYOUT.
tech (technical field)
value set: SPACE, 'X' 'X' = technical field
Field cannot be output in the list and cannot be displayed interactively.
Field can only be used in the field catalog (not in IT_SORT, ...).
emphasize (highlight columns in color)
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)
value set: SPACE, 'X'
'X' = column cells are output as hotspots
fix_column (fix column)
value set: SPACE, 'X'
Not relevant for block lists (output of several lists consecutively)
'X' = column fixed (does not scroll horizontally)
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. See also the documentation of the Layout parameter
IS_LAYOUT-NO_KEYFIX of the IMPORTING paramter IS_LAYOUT.
do_sum (sum over column)
value set: SPACE, 'X' 'X' = a sum is to be calculated over this internal output table field.
This function can also be called by the user interactively.
no_sum (sums forbidden)
value set: SPACE, 'X' 'X' = no sum can be calculated over this field, although the data type of the field would allow summing.
input (column ready for input)
Function not available
Format column contents
icon
value set: SPACE, 'X' 'X' = column contents to be output as an icon.
The caller must consider the printability of icons.
symbol
value set: SPACE, 'X' 'X' = column contents are to be output as a symbol.
The internal output table column must be a valid symbol character.
The caller must consider the printability of symbols.
Symbols can usually be printed, but may not always be output correctly, depending on the printer configuration.
just (justification)
value set: SPACE, 'R', 'L', 'C'
Only relevant for fields of data type CHAR or NUMC
' ' = default justification for this data type
'R' = right-justified output
'L' = left-justified output
'C' = centered output
The justification of the column header always follows the justification of the columns. Independent justification of the column neader is not possible.
lzero (leading zeros)
value set: SPACE, 'X'
Only relevant for fields of data type NUMC
ALV outputs NUMC fields right-justified without leading zeros by default.
'X' = output with leading zeros
Note: If a NUMC field is output left-justified or centered by FIELDCAT-JUST, leading zeros are output. If the output of leading zeros is suppressed by a Data Dictionary reference ALPHA conversion exit, the output is always left-justified.
no_sign (no +/- sign) Only relevant for 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)
value set: SPACE, template
template = see documentation of WRITE formatting option USING EDIT MASK template
The output conversion conv can be made by template = '== conv'.
Texts
The following text parameters should be specified for program fields without a Data Dictionary reference. 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. popups.
seltext_l (long field label)
seltext_m (medium field label)
seltext_s (short field label)
reptext_ddic (header)
analogous to the Data element maintenance 'Header'
The specified text is not necessarily output in the list, an optimum among all texts is sought.
ddictxt (specify text)
value set: SPACE, 'L', 'M', 'S'
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.
Parameters for program fields without Data Dictionary reference
see also 'Text' parameters
datatype (data type)
value set: SPACE, Data Dictionary data type (CHAR, NUMC,...)
Only relevant for fields without Data Dictionary reference
Program field data type
ddic_outputlen (external output length)
value set: 0 (initial), n
Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
Prerequisites:
FIELDCAT-EDIT_MASK = '==conv'
see also the documentation of the parameter FIELDCAT-EDIT_MASK
FIELDCAT-INTLEN = n
see also the documentation of the parameter FIELDCAT-INTLEN
n = external format field output length
The column width FIELDCAT-OUTPUTLEN need not be the same as the external format output length (FIELDCAT-DDIC_OUTPUTLEN).
intlen (internal output length)
value set: 0 (initial), n
Only relevant for fields without Data Dictionary reference whose output is nevertheless to be modified by a conversion exit.
Prerequisites:
FIELDCAT-EDIT_MASK = '==conv'
see also the documentation of the parameter FIELDCAT-EDIT_MASK
FIELDCAT-DDIC_OUTPUTLEN = n
see also the documentation of the parameter FIELDCAT-DDIC_OUTPUTLEN
n = internal format field output length
rollname (data element)
value set: SPACE, Data Dictionary data element name
F1 help can be provided for a program field without a Data Dictionary reference, or F1 help which differs from the Data Dictionary help can be provided for a field with a Data Dictionary reference, using this parameter.
When F1 help is called for this field, the documentation of the specified data element is displayed.
If the FIELDCAT-ROLLNAME is initial for fields with a Data Dictionary reference, the documentation of the data element of the referred Data Dictionary field is output.
Others
sp_group (field group key)
value set: SPACE, CHAR(1)
Field group key.
Keys are assigned to group names in the IT_SPECIAL_GROUPS parameter (see also the documentation of the parameter IT_SPECIAL_GROUPS).
When such an assignment is made in the field catalog and in IT_SPECIAL_GROUPS, the fields are grouped correspondingly in the display variant popup.
reprep (Report/Report interface selection criterion)
value set: SPACE, 'X'
Prerequisites:
The system contains the Report/Report interface (function group RSTI, table TRSTI)
Parameter LAYOUT-REPREP = 'X'
(see also the documentation of the parameter LAYOUT-REPREP of the IMPORTING parameter IS_LAYOUT )
'X' = When the Report/Report interface is called, the value of this field is passed in the selected interface start record as a selection criterion.
2.7.2. Default
The following entries are usually sufficient for internal table fields with a reference to a field defined in the Data Dictionary :
fieldname
ref_tabname
Notes:
ALV gets the remaining information from the Data Dictionary.
If no relative column position (COL_POS) is specified, the fields are output in the list in the order in which they were added to the field catalog.
REF_FIELDNAME need only be specifid when the name of the internal table field differs from the name of the referred Data Dictionary field.
Information which is explicitly entered in the field catalog is not overwritten by information from the Data Dictionary.
Priority rule:
Entries in the field catalog have priority over differing entries in the Data Dictionary.
The following entries are usually sufficient for internal table fields without a reference to the Data Dictionary (program fields):
fieldname
outputlen
datatype
seltext_s
seltext_m
seltext_l
Notes:
F1 help can be provided for program fields by assigning a data element to the parameter ROLLNAME.
If the parameters SELTEXT_S, SELTEXT_M, SELTEXT_L, and REPTEXT_DDIC contain appropriate field labels, the program field column headers are also adjusted appropriately when the column width changes

Error while creating import parameters in RFC function module

Hi,
I am trying to create import parameter in RFC enabled function module and getting the following error "Reference parameters are not allowed with RFC". Am I doing something wrong.
Your earlier response is much appreciated
Regards
Kasi

There is a "Pass by Value" checkbox, just check that and you wont get the error. The basic reason behind is since an RFC is called by a different system the parameters have to be sent as values than as references.

Get Import Parameters of a Function Module

Hi,
Is there a way to find the import parameters and their Data Type of a Function Module in any Table??
For example, i know i can find the name and the include of the Funtion Module in TFDIR. Is there anywhere i can find the list of Import Parameters and their Data Types??
Thanks and Regards,
Kaeyur

you can use
Data: lv_type type c.
clear:lv_type.
DESCRIBE FIELD p_bukrs TYPE lv_type.
It will return C as its type C and p_bukrs is selection screen parameter.
hope this helps.

Doubt in export, import and table para when creating Function Module

Dear fellow ABAPers,
I have a doubt in defining export, import and table parameter while creating a function module.
I am calling a function module inside a user exit. Now in the user exit the SAP fills an internal table called i_lfa1 with all the data user has eneterd.
Now I want to pass this whole internal table to function module and the perform some checks on the values of internal table.
After that function module fills an error structure with values depending on some check.
1)
How do I pass this internal table to function module ?
When I am creating function module in se37 where do I define this iternal table type ? Is it in Import or Table parameter during function module creation?
2)
Where do I define error structure type (which is returned by function module to main program)? Is it in Export or table parameter during function module creation?
Please clear my doubt..
Relevant points will be awarded.
Regards,
Tushar.

Hi Tushar,
1. How do I pass this internal table to function module ?
   I assume u are creating your own Y/Z FM.
   Pass it thru TABLES parameter.
2. When I am creating function module in se37 where do I define this iternal table type
   Define this in TABLES interface.
   What Type ?
   THE SAME TYPE WHICH HAS BEEN DEFINED
    WHILE PASSING IN THE USER-EXIT FUNCTION MODULE.
   IF U SEE THE FM OF THE USER-EXIT,
   U WILL COME TO KNOW.
3.
Where do I define error structure type (which is returned by function module to main program)? Is it in Export or table parameter during function module creation?
Define it in TABLES interace. (not in export, import)
(Since what u are going to return is an internal table)
U can take for eg. BDCMSGCOLL.
OR u can create your own Y/Z structure
for the same purpose.
(or u can use the structure type T100)
I hope it helps.
Regards,
Amit M.

Short text         Select Options Field PO number
Compenent Compent type
SIGN       BAPISIGN      Inclusion/exclusion criterion SIGN for range tables
OPTION       BAPIOPTION      Selection operator OPTION for range tables
LOW       EBELN                      Purchasing Document Number
HIGH       EBELN                      Purchasing Document Number
In the function module import
give as
I_PO_NUM     TYPE     Z_TT_PONUM     opt pass value Select options PO Number
Hope this is exactly what you want to know.
So you create a structure simliar to mine but the low an high whould be your component
then a table type and then include that in the BAPI.
Then pass your select-option value to this BAPI when you call this BAPI in the program

How to import a range in Function module?

I am using a Function module in which material is getting imported.
In the import tab we have
Parameter Name Typing Associated Type optional pass value
IM_MATERIAL TYPE MATNR <checked> <checked>
So when the Function module is execute we can enter only one value into the IM_MATERIAL.
But now it has to be enhanced for entering multiple values. How to import the material as a range?
Please throw light.
Thanks.

Hi
If you are using a select-options you can use this approach.
TABLES: MARA.
DATA: RANGE TYPE WRF_MATNR_RANG_TTY.
SELECT-OPTIONS: SO_MATNR FOR MARA-MATNR.
START-OF-SELECTION.
RANGE[] = SO_MATNR[].
CALL FUNCTION 'ZTEST'
EXPORTING
 I_RANGE = RANGE.
Where I_RANGE is defined using this table type WRF_MATNR_RANG_TTY
Parameter Name Typing Associated Type optional pass value
I_RANGE TYPE WRF_MATNR_RANG_TTY <checked> <checked>

RFC function module with call transaction and Import memory ID

Hi,
I am calling RFC function module from R/3 which exists in BW.
In BW stand alone function module works fine.
When I am Calling from R/3 it is not working,
Can you tell me is it because of the below code, And suggest if any corrections required.
I am calling the call transaction and using EXPORT memory iD inside the program
and IMPORT in after that.
And populating RFC table's table " p_i_tcode_user" finally.
set parameter id 'TCD' field p_tcode.
call transaction 'Z_BW_RSUSR002' AND SKIP FIRST SCREEN.
ENDIF.
get the final user data from submitted program
import gt_users_complete from memory id tcode_userid.
LOOP AT gt_users_complete.
      lwa_tcode_user-tcode = p_tcode.
      lwa_tcode_user-uname = gt_users_complete-Bname.
      APPEND lwa_tcode_user TO p_i_tcode_user.
ENDLOOP.
Thanks,
Veerendra.

HI,
   Can you just exaplin it clearly plz..
Thanks

Any example to import and export itab to function module

hi all,
as the table parameter in function module is obsolete, please advise an example on how to pass in an internal table
and return back the result in an internal table as well.
for example, i have itab1 and itab2. By using table parameters i got the following code. Please advise alternative way by using import and export.
""Local Interface:
*" TABLES
*"      itab1 STRUCTURE Zitab1
*"      itab2 STRUCTURE Zitab2
loop at itab1 into wa_itab.
**do some logic here to assign value to itab2 and return.
wa_itab2-a = xxx .
wa_itab2-b = xxx.
append wa_itab2 to itab2.
endloop.
thank you.

hi,
suppose you have two structure name struc1 and struc2.
create table type zitab1 & 2 for both.
please do the following:
""Local Interface:
*" IMPORTING
*"     VALUE(itab1) TYPE Zitab1
*" EXPORTING
*"     VALUE(itab2) TYPE Zitab2
you can avoid to use the obsolete table parameters as well as LIKE in function module creation.
cheers

Function module import parameter

I had used a bapi in the program and i got a dump.
then i recetified the dump. But kindly tell me the
reason .
My program is like this..
Report xyz.
DATA wa_bapireturn TYPE bapireturn.
DATA it_bapireturn LIKE TABLE OF wa_bapireturn.
DATA wa_bapisdstat TYPE bapisdstat.
DATA it_bapisdstat LIKE TABLE OF wa_bapisdstat.
PARAMETERS p_vbeln LIKE vbap-vbeln.
START-OF-SELECTION.
CALL FUNCTION 'BAPI_SALESORDER_GETSTATUS'
    EXPORTING
      salesdocument = so_vbeln
    IMPORTING
      return        = it_bapireturn
    TABLES
      statusinfo    = it_bapisdstat.
now i got the dump because i have used
it_bapireturn for importing.
then i modified the program like..
CALL FUNCTION 'BAPI_SALESORDER_GETSTATUS'
    EXPORTING
      salesdocument = so_vbeln
    IMPORTING
      return        = wa_bapireturn
    TABLES
      statusinfo    = it_bapisdstat.
Now the program working fine because i passed
wa_bapireturn. please tell me why it happened like
this. How to know when to pass internal table and when to
pass just a structure.
And also tell me the difference bet type and type ref to.

As per the interface definition of the BAPI, it expects one workarea in the RETURN parameter.
but it_bapireturn was an internal table so was the dump
but wa_bapireturn is a work area so it worked.
You can check the interface of the Function Module to know what to be used. Usually work areas are passed in IMPORT AND EXPORT parameters and internal tables in TABLES parameters.
by using TYPE , we create a variable of a pre difined TYPE.
by using TYPE REF we create object of a particual class
