Add button is not displaying values correctly in table control. ABAP

[Former Member]

Only material number and the quantity is being displayed when i press the add button. Also, when i try to add more records into the table, it just replaces the first line and the first entry i entered is not shown. Screen shot of the output is attached.

The table control was created using the wizard. I cannot find the problem. Please Help

Here is my code:

 *INCLUDE
DATA: BEGIN OF BOM_STRUC,

    MANDT(3) TYPE c,

    MNUM TYPE Z032_ITEM_DATATYPE,

    INAME TYPE Z032_INAM_DATATYPE,

    BQUA TYPE INT4,

    PRUNIT(4) TYPE c,

    END OF BOM_STRUC.

    data: it_BOM like sorted TABLE OF BOM_STRUC with unique key MNUM,

          wa_BOM like BOM_STRUC.

*MAIN PROGRAM
MODULE USER_COMMAND_3031 INPUT.
CASE OK_CODE.

WHEN 'ADD'.

            BOM_STRUC-MNUM = MAT_NUM.

            BOM_STRUC-INAME = MAT_NAME.

            BOM_STRUC-BQUA = BQUA.

            BOM_STRUC-PRUNIT = PRUNIT.

            APPEND BOM_STRUC TO IT_BOM.
ENDCASE.

ENDMODULE.

The "CASE OK_CODE" block should be in the module BOM_TBL_USER_COMMAND or USER_COMMAND_3031.

Sorry, I just forgot to add that part of the code here. i just updated it. The "CASE OK_CODE" block is in the module USER_COMMAND_3031

You need to pass number of records to table line field

DESCRIBE TABLE IT_BOM LINES TABLE_CONTROL_NAME-LINES

Hi Josh Dang-Il,

Try to declare structure BOM_STRUC, Internal table(IT_BOM), and Workarea(WA_BOM) in the main program of this screen, Then value of internal table and workarea will available in whole program.

Dont declare in any include programs, Declaration you can do in Main Program.

Try this it may help you.

Thanks,

Sivaraj Sadasivam.
