Balu483 — Mon, 11 Jan 2016 11:04:13 GMT

in table control i want to modify table control internal table after user PRESS ENTER .

but internal table is not getting modified it is giving sy-subrc = 4.

please help me how to modify internal table and display the data in table control in module pool program

my logic:

FLOW LOGIC:

PROCESS BEFORE OUTPUT.

MODULE status_0483."""for pf status

LOOP AT gt_fdint INTO gs_fdint WITH CONTROL tab_con CURSOR

tab_con-current_line.

ENDLOOP.

PROCESS AFTER INPUT.

LOOP AT gt_fdint .

CHAIN.

FIELD gs_fdint-zselno.

FIELD gs_fdint-zcustm.

FIELD gs_fdint-zfddes.

FIELD gs_fdint-zstart.

FIELD gs_fdint-zenddt.

FIELD gs_fdint-zaccrl.

FIELD gs_fdint-zintrs.

FIELD gs_fdint-zintdes.

FIELD gs_fdint-zpstdt.

FIELD gs_fdint-channel.

MODULE tc_acunt_modify ON CHAIN-REQUEST.

ENDCHAIN.

ENDLOOP.

MODULE user_command_0483."""USER COMMAND SUBROUTINE

MODULE exit_command_483."""EXIT COMMAND SUBROUTINE

MODULE tc_acunt_modify INPUT.

MODIFY gt_fdint

FROM gs_fdint

INDEX tab_con-current_line.

ENDMODULE.

hear internal table is initially contains no record, if i give sone input in table control and press enter then

MODULE tc_acunt_modify ON CHAIN-REQUEST. is triggering and but it is not modifying the internal table

after MODIFY statement it is giving SY-SUBRC = 4.

Hi,

first insert a initial line in the internal table and then modify the same as below.

PROCESS AFTER INPUT.

LOOP AT gt_fdint .

CHAIN.

FIELD gs_fdint-zselno.

FIELD gs_fdint-zcustm.

FIELD gs_fdint-zfddes.

FIELD gs_fdint-zstart.

FIELD gs_fdint-zenddt.

FIELD gs_fdint-zaccrl.

FIELD gs_fdint-zintrs.

FIELD gs_fdint-zintdes.

FIELD gs_fdint-zpstdt.

FIELD gs_fdint-channel.

Module tc_insert_line ON CHAIN-REQUEST.

MODULE tc_acunt_modify ON CHAIN-REQUEST.

ENDCHAIN.

ENDLOOP.

MODULE user_command_0483."""USER COMMAND SUBROUTINE

MODULE exit_command_483."""EXIT COMMAND SUBROUTINE

MODULE tc_insert_line INPUT.

READ TABLE gt_fdint INDEX tab_con-current_line TRANSPORTING NO FIELDS.

IF sy-subrc <> 0.

INSERT INITIAL LINE INTO gt_fdint INDEX tab_con-current_line.

ENDIF.

ENDMODULE. " tc_insert_line INPUT

MODULE tc_acunt_modify INPUT.

MODIFY gt_fdint

FROM gs_fdint

INDEX tab_con-current_line.

ENDMODULE.

Hope this helps.

Hi Chandu,

Modify statement never insert a new record in internal table.

MODIFY gt_fdint

FROM gs_fdint

INDEX tab_con-current_line.

IF sy-subrc <> 0.

INSERT gs_fdint INTO gt_fdint INDEX tab_con-current_line.

ENDIF.

Hope it helpful,

Regards,

Venkat.

Create your table control using the table control wizard rather than doing it be hand.
