Hi KPN,
Sorry for the delay in reply.
the table what u've written is right but it no way help me in this Form routine exit.
I want to update the value to Profit center field for  Price difference GL Account which will be derived only at the time of posting MIRO.
FYI: Pls go thru the std report,I've copied it into Z report and assigned a Form routine and inside to that I've to declare my coding part.
Report : RGGBS000.
Regards
Sankar.
