Hi,

What code have you written in the PAI ? As you click on the scroll bar, your PAI is called everytime. Now depending on the code that you have written that is being triggered, Please check the code in debugging mode, see where your control is going whenever you press the scroll up or down.

Hi,

It is because while scrolling Table Control PAI will trigger and execute the code as usual.So if the OK code is set for delete or something it will perform that.So check your code wheter u written any code for deleting entry and that getting triggered while scrolling

Hi,

All you need to do is to modify the internal table whenever you perform some user action.

it_zekpo is my internal table w/o header line,

wa_zekpo is work area.

Name of input/output fields on screen are:-

wa_zekpo-field1,

wa_zekpo-field2, and so on...

Use code:-

At screen logic:-

PROCESS BEFORE OUTPUT.
*  MODULE status_8003.
 
  LOOP WITH CONTROL po_tab. "po_tab is table control on screen 8003
    MODULE read_data.
  ENDLOOP.
 
PROCESS AFTER INPUT.
*  MODULE user_command_8003.
 
  LOOP WITH CONTROL po_tab.
    MODULE modify_data. "<----you need this code
  ENDLOOP.

In PBO:-

*&---------------------------------------------------------------------*
*&      Module  READ_DATA  OUTPUT
*&---------------------------------------------------------------------*
MODULE read_data OUTPUT.

  "read entries from internal table to table control
  READ TABLE it_zekpo INTO wa_zekpo INDEX po_tab-current_line. "<-po_tab is table control name

  DATA line_count TYPE i.
 
  DESCRIBE it_zekpo
  LINES line_count.
 
  po_tab-lines = line_count + 10. "<-to increase the number of lines in table control dynamically
 
ENDMODULE.                 " READ_DATA  OUTPUT

In PAI:-

*&---------------------------------------------------------------------*
*&      Module  MODIFY_DATA  INPUT
*&---------------------------------------------------------------------*
MODULE MODIFY_DATA INPUT.

  "this will modify the contents of existing line from table control to internal table
  MODIFY IT_ZEKPO FROM WA_ZEKPO INDEX po_tab-currentline.

ENDMODULE.                 " MODIFY_DATA  INPUT

Hope this helps you.

Hello,

This usually happens in table control.Just take care of few things.

1. When ever you will scroll PAI will be triggered.So you have to develop a logic in such a way thatinternal table data does not get deleted.

2. Whenever you want to scroll just do /H and debug it.You will able to anaylse your code more effectively.

3. Do everything in PAI related to scrolling.

Hi,

Every time you scroll down or up the table control, the PAI is triggered. There is no exclusive sy-ucomm value for the scrolling action.

What you could possibly do is, restrict the portions of code that you have written with its respective sy-ucomm values.

if sy-ucomm is 'F_DELETE'.  "This way, your code gets triggered only for the events that you want.
   "Your operation
endif.
