Internal table not getting modified from Table Control

[former_member434229]

Hi Guys,

I am developing a <b>Module Pool </b>Program where I am inserting data directly in table control of the main screen.

In the flow logic of the Table control I have written :

PROCESS BEFORE OUTPUT.

LOOP AT itab WITH CONTROL tc1 CURSOR tc1-current_line.

MODULE read_data.

ENDLOOP.

MODULE status_0100.

PROCESS AFTER INPUT.

LOOP AT itab.

MODULE mod_data.

ENDLOOP.

MODULE user_command_0100.

Module mod_data input.

MODIFY itab INDEX tc1-current_line.

Endmodule.

At modify, when I am debugging it's showing sy-subrc = 4 (Entry not appending in Int Table though it is there in the header line). But, if I use append itab, it's working (Problem is that while inserting 2nd record a copy of first record is also appending which I don't want).

Please let me know what's wrong in Modify statement or what is solution for inserting records of tablecontrol in internal table.

TIA,

Nitin

Try using the read statement as below:

Module mod_data input.

READ TABLE itab INDEX tc1-current_line.

if sy-subrc = 0.

MODIFY itab INDEX sy-tabix..

endif.

Endmodule.

Try to use work area

MODIFY G_TC2_ITAB

FROM G_TC2_WA

INDEX TC2-CURRENT_LINE.

Hi Nitin,

Try the following code for Module.

MODULE MOD_DATA INPUT.

READ TABLE ITAB INDEX TC1-CURRENT_LINE.

IF SY-SUBRC = 0.

MODIFY itab INDEX tc1-current_line.

ELSE.

APPEND ITAB.

ENDIF.

Endmodule.
