Hi,

I have redone the scenario and follow the steps it will work....

STEP 1: Create an internal table with field for selection in table.

STEP 2: Assign the selection field in the table control for the line selection.

STEP 3: Now whenever the line is selected, the selection field will have a field 'X'. 

STEP 4: In PAI Modify the table fields those are selected with 'X'. 

STEP 5: Set a flag in PAI, flag = 'X'.

STEP 6: In PBO set a condition .         " We set a flag so that we fetch the data only once.
If flag NE 'X'.
Fetch data.
endif.


 Data:
      begin of ztable,
         ID type char4,
         Name type char30,
         Sel type c,
      end of ztable.

PROCESS BEFORE OUTPUT.
  MODULE STATUS_0100.
  LOOP AT ITAB INTO FS WITH CONTROL EMP CURSOR W_I.
    MODULE UPDATE.
  ENDLOOP.

*
PROCESS AFTER INPUT.
  LOOP AT ITAB.
  MODULE APPEND.
  ENDLOOP.
  MODULE USER_COMMAND_0100.

INCLUDE YMODTOP                                 .    " global Data

*&---------------------------------------------------------------------*
*&      Module  UPDATE  OUTPUT
*&---------------------------------------------------------------------*

  IF FL_FLAG <> 1.
    SELECT * FROM ZTABLE INTO CORRESPONDING FIELDS OF TABLE ITAB.
  ENDIF.
ENDMODULE.                 " STATUS_0100  OUTPUT

*&---------------------------------------------------------------------*
*&      Module  append  INPUT

not the data issue.

thanks

hi,

The selection is not updated because the table is not getting updated when ever you are trying to display them back as the PBO will get triggered and the select statement in the PBO module gets executed

without the updated data...

your selection button is getting cleared every time you trigger an event so for that you need to declare another field with character 1 and update it with 'X'.

So your selection will remain even when you trigger an event check the code i gave in the previous post for that,

your problem will be solved.

Thanks&Regards
