Update Likp table from HUPAST

Question

I've a scenerio where i've to updated LIKP table, when user save the HUPAST. I've created the BDC program which update the likp table using VL02N transacton. but when i'm calling the BDC from a BADI its giving a error, as i'm trying to update the same delivery number. (Delivery already updated by user).
I'm now trying using events, i've traced an event CHANGED in object type LIKP , which is fired when HUPAST is saved.
How do i update the event changed ??? and call the bdc program from the event.
pls share .

hi,
You can do it PAI under module USER_COMMAND. and you can use standard UPDATE/MODIFY/DELETE statements to update ur database table and make sure u use a commit work after the use of ablove mentioned statements.
kindly check this.
PROCESS BEFORE OUTPUT.
MODULE status_9010.
LOOP WITH CONTROL tab_control.
MODULE move_data_to_table.
ENDLOOP.
PROCESS AFTER INPUT.
LOOP WITH CONTROL tab_control.
MODULE move_data_from_table.
ENDLOOP.
*& Module move_data_to_table OUTPUT
This is to move the data from the internal table to the table control
MODULE move_data_to_table OUTPUT.
This is to move the data from the internal table to the table control
zmpets_mode-modecode,zmpets_range-rangeid,zmpets_servfacto-factor are column name of table control
READ TABLE int_factor INDEX tab_control-current_line.
IF sy-subrc = 0.
zmpets_mode-modecode = int_factor-modecode.
zmpets_range-rangeid = int_factor-rangeid.
zmpets_servfacto-factor = int_factor-factor.
ENDIF.
ENDMODULE. " move_data_to_table OUTPUT
*& Module move_data_from_table INPUT
Date is moved from the table control to the Internal Table
MODULE move_data_from_table INPUT.
To move the data from the table control to internal table 'INT_FACTOR'.
int_factor-modecode = zmpets_mode-modecode.
int_factor-rangeid = zmpets_range-rangeid.
int_factor-factor = zmpets_servfacto-factor.
*here if the data is there, it will modify
MODIFY int_factor INDEX tab_control-current_line.
IF sy-subrc NE 0. "data not exixting in table control . ie new data, then append it
APPEND int_factor.
CLEAR int_factor.
ENDIF.
ENDMODULE. " move_data_from_table INPUT
