Table control values not getting modified and values are getting vanished

[Former Member]

In the Screen, i have put a Table control and fields are from workarea wa_item

PBO

-

---

LOOP AT it_item INTO wa_item WITH CONTROL tc CURSOR tc-current_line.

ENDLOOP.

PAI

-

---

LOOP at it_item.

module modify_it.

ENDLOOP.

MODULE it_modify INPUT.

MODIFY it_item FROM wa_item INDEX tc-current_line.

The above modify statement is failing with a sy-subrc of 4.

wa_item holds the value what we have entered in the table control first line and tc-current_line value is 1.

But it is not modifying the internal table and thus value is not getting displayed in the sceen(Table control) after pai & Pbo.

Pls Help.....

Hi Shaik,

Use this code, its working:-

At screen logic

PROCESS BEFORE OUTPUT.
*  MODULE status_8002.

  LOOP WITH CONTROL po_tab. "table control name
    MODULE pass_data.
  ENDLOOP.

PROCESS AFTER INPUT.
*  MODULE user_command_8002.

  LOOP WITH CONTROL po_tab. "table control name
    MODULE modify_data.
  ENDLOOP.

In PBO

MODULE pass_data OUTPUT.
  READ TABLE it_item into wa_item INDEX po_tab-current_line.
ENDMODULE.                 " PASS_DATA  OUTPUT

In PAI

MODULE modify_data INPUT.
  MODIFY it_item INDEX po_tab-current_line FROM wa_item.
ENDMODULE.                 " MODIFY_DATA  INPUT

Hope this solves your problem.

Thanks & Regards,

Hi,

Are you using any SELECT query or filling data into internal table it_itembefore LOOP..ENDLOOP in PBO.

If yes, then the modifications done on internal table it_item in PAI are overwritten in PBO and TC comes blank.

PBO

-

---

LOOP AT it_item INTO wa_item WITH CONTROL tc CURSOR tc-current_line.

ENDLOOP.

Otherwise ur code seems to be all right.
