1 Fieldname 2 Outputlen
3 Datatype 4 seltext_s
5 seltext_m 6 seltext_l
•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.
Defaults :
The following entries are usually sufficient for internal table fields with a reference to a field defined in the Data Dictionary :

•
FORM set_pf_status USING rt_extab TYPE slis_t_extab
•The table RT_EXTAB contains those function codes that are hidden on the standard interface.
The structure RS_SELFIELD contains information:
· tabname : internal output table name

•
IT_FILTER
• Filter criteria for first list output
• Filter criteria which result, e.g. from explicitly loading an initial display variant, can be passed to list output in this parameter. This table should never be built-up 'manually'.
I_DEFAULT
• Initial variant logic active/inactive.
• Prerequisite: The parameter IS_VARIANT has the appropriate value
Value Range
SPACE = no initial variant can be defined 'X' = initial variant can be defined
Default SPACE
I_SAVE - variants can be saved
• Value Range
– ' ' = display variants cannot be saved
– 'X' = standard save
– 'U' = only user-specific saving
– 'A' = standard and user-specific saving
IS_VARIANT
• This structure is only relevant if display variants are to be saved and/or read
• The access path must be specified in the fields
– REPORT (required field),
– HANDLE (optional) unique user-assigned CHAR(4) field
– LOG_GROUP (optional)
I_INTERFACE_CHECK
•To avoid overloading list output with interface consistency checks, they are only made in an extra call mode.
•If this parameter is 'X', the consistency of the interface is checked when the function module is called, and an error log is output.
•This parameter should only be set for development test purposes (e.g. in debugging).
•The interface check can also be made on the results list by entering the function code &SOS.
IS_PRINT
• Print information
• Print control parameter
– PRINT
– NO_PRINT_SELINFOS
– NO_COVERPAGE
– NO_NEW_PAGE
– RESERVE_LINES

• Delete list in CALLBACK_USER_COMMAND
– Parameter which states whether the caller left the list (SELFIELD-EXIT = 'X') in CALLBACK USER_COMMAND
ES_EXIT_CAUSED_BY_USER
• How the user left the list
– If one of the ALV standard function codes for 'Back', 'Cancel' or 'Exit' occurs, the current list is discarded and the ALV function module ends. In this case the exporting structure ES_EXIT_CAUSED_BY_USER contains one of the following flags:
ES_EXIT_CAUSED_BY_USER-BACK = 'X‘
'Back' occurred
ES_EXIT_CAUSED_BY_USER-CANCEL = 'X'
'Cancel' occurred
ES_EXIT_CAUSED_BY_USER-EXIT = 'X'
'Exit' occurred
– The function which occured determines the further navigation in the application.
T_OUTTAB
• Table with data to be displayed
– This table can contain more fields than are relevant for the list output (display fields and field list). Only the fields named in field catalog and the layout structure are used for the list output. Other internal table fields are ignored.

SPACE = no initial variant can be defined 'X' = initial variant can be defined
Default SPACE
I_SAVE - variants can be saved
• Value Range
– ' ' = display variants cannot be saved
– 'X' = standard save
– 'U' = only user-specific saving
– 'A' = standard and user-specific saving
IS_VARIANT
• This structure is only relevant if display variants are to be saved and/or read
• The access path must be specified in the fields
– REPORT (required field),
– HANDLE (optional) unique user-assigned CHAR(4) field
– LOG_GROUP (optional)
I_INTERFACE_CHECK
•To avoid overloading list output with interface consistency checks, they are only made in an extra call mode.
•If this parameter is 'X', the consistency of the interface is checked when the function module is called, and an error log is output.
•This parameter should only be set for development test purposes (e.g. in debugging).
•The interface check can also be made on the results list by entering the function code &SOS.
IS_PRINT
• Print information
• Print control parameter
– NO_PRINT_SELINFOS
– NO_COVERPAGE
– NO_NEW_PAGE
– RESERVE_LINES
– END_OF_PAGE
– NO_PRINT_LISTINFOS
– NO_CHANGE_PRINT_PARAMS
SCREEN_SETTINGS
• Coordinates for list in dialog box
– Only to be used if the list is output in a popup.
– IT_SCREEN_START_COLUMN
• x coordinate of the top left-hand corner of the popup.
– IT_SCREEN_END_COLUMN
• x coordinate of the bottom right-hand corner of the popup.
• Coordinates for list in dialog box
– Only used if the list is output in a popup.
– IT_SCREEN_START_LINE
• y coordinate of the top left-hand corner of the popup.
– IT_SCREEN_END_LINE
• y coordinate of the bottom right-hand corner of the popup.
E_EXIT_CAUSED_BY_CALLER
• Delete list in CALLBACK_USER_COMMAND
– Parameter which states whether the caller left the list (SELFIELD-EXIT = 'X') in CALLBACK USER_COMMAND
ES_EXIT_CAUSED_BY_USER
• How the user left the list
– If one of the ALV standard function codes for 'Back', 'Cancel' or 'Exit' occurs, the current list is discarded and the ALV function module ends. In this case the exporting structure ES_EXIT_CAUSED_BY_USER contains one of the following flags:
ES_EXIT_CAUSED_BY_USER-BACK = 'X‘
'Back' occurred
ES_EXIT_CAUSED_BY_USER-CANCEL = 'X'
'Cancel' occurred
ES_EXIT_CAUSED_BY_USER-EXIT = 'X'
'Exit' occurred
– The function which occured determines the further navigation in the application.
T_OUTTAB
• Table with data to be displayed
– This table can contain more fields than are relevant for the list output (display fields and field list). Only the fields named in field catalog and the layout structure are used for the list output. Other internal table fields are ignored.
– If the internal table is defined in the calling program without a header, no F1 help is possible in the list.
“REUSE_ALV_LIST_DISPLAY” EXCEPTIONS
• Program errors
– Exception type
• If the exception is not handled by the calling program, the following applies:(X) an error message is sent.( ) a termination message is sent.( ) a runtime error occurs.

Sap Script Version Management
Problem :can we roll back to an older version in sap scripts ?suppose i have made some changes in the existing code for the Script ,so i end up getting a revised version. but later i'm being told to get back to the older version . is it possible to activate the older version for SAP Scripts .?
Solution: Follow the steps..1. In production, execute the program RSTXSCRP,in sel.scrren - Object Name : give ur script namemode : EXPORTdataset name : blank now execute,2. It will ask for a filename, save the file as .TXT
3. In Devlopment, execute the same program RSTXSCRP,in sel.scrren - Object Name : give ur script namemode : IMPORTdataset name : blank now execute,4. It will ask for a filename, give the same file which u have transfered from PROD and execute.....
As a result of above solution , we can copy the live sapscript working in production to our developed sapscript in development and vice cersa , this will make sure that we have both the versions same . this is my answers to sap not providing version management for sapscripts
