hi aditya,

this problem ocuurs when we dnt keep a track of the PAI and PBO. do 1 thing declare a variable that keeps a track of the PBO and PAi.

declare that initially 0 and den everytime when the PAI or PBO of that particular screen is called...change the value to 1.

when the fields get disabled..check the properties of that particular firld in the screen layout..

hope this helps

with best regards

Try making LINES parameter of your tablecontrol as zero '0' in PBO.

Hi Aditya Shrivastava,

If you want to add new records into the table, and on the screen you have a table control which is not enabled (i.e., empty line are greying out).

I suppose in this case its better to have a button for edit mode, which enables the table control for accepting new entries (initially your table control is in output mode only).

Now, place a button 'EDIT' using a pf-status, and then use this code to enable your table control.

And a button 'SAVE' for saving the entries into the database.

Use this code:-

At screen flow logic.

************************************************************************************************************************

PROCESS BEFORE OUTPUT.

MODULE STATUS_8001. "For PF-Status

LOOP WITH CONTROL MOVIE.

MODULE PASS_DATA. "Selects the records and passes to the table control

MODULE MODIFY_SCREEN_8001. "Enables table control for accepting new entries

ENDLOOP.

PROCESS AFTER INPUT.

LOOP WITH CONTROL MOVIE.

MODULE DISPLAY_DATA. "Displays data in the table control

MODULE SAVE_DATA. "Save the modified entries or new entries.

ENDLOOP.

************************************************************************************************************************

Code for the module.

************************************************************************************************************************

MODULE MODIFY_SCREEN_8001 OUTPUT.

OK_CODE = SY-UCOMM.

CASE OK_CODE.

WHEN 'EDIT'.

LOOP AT SCREEN.

IF ( SCREEN-GROUP1 = 'XYZ' ).

SCREEN-ACTIVE = 1.

SCREEN-INPUT = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDCASE.

ENDMODULE. " MODIFY_SCREEN_8001 OUTPUT

************************************************************************************************************************

MODULE SAVE_DATA INPUT.

OK_CODE = SY-UCOMM.

CASE OK_CODE.

WHEN 'SAVE'.

MODIFY <internal_table> INDEX <table_control_name>-CURRENT_LINE.

UPDATE <database_table> FROM TABLE <internal_table>.

LOOP AT SCREEN.

IF ( SCREEN-GROUP1 = 'XYZ' ).

SCREEN-ACTIVE = 0.

SCREEN-INPUT = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDCASE.

ENDMODULE. " SAVE_DATA INPUT

************************************************************************************************************************

Now when you click EDIT button, your table control will be enabled to accept new entries.

When you click SAVE button, it will again disable the table control (output mode only) and the database will be modified.

Hope this solves your problem.
