Inside you loop on the control items, use the command:

FIELD <fieldname> MODULE <field module>.

Hi Shivaa,

IN PAI;

LOOP AT control items.

CHAIN.

FIELD vbap-netpr

MODULE validate ON REQUEST.

MODULE modify_tbl ON CHAIN-REQUEST.

ENDCHAIN.

ENDLOOP.

And then double click on module validate write below code:

MODULE validate INPUT.

if vbap-netpr lt zcom.

message w013(xxx) with 'Error'.

endif..

ENDMODULE.

And then double click on module modify write below code:

MODULE modify_tbl INPUT.

MODIFY it_control from vbap index items-current_line.

ENDMODULE.

Hope it may help you.

Regards,

Supriya.
