Hi Karthi
Thank you so much for the reply.
I have already checked this BADI however there is an issue here.
We have actually developed a custom report with some selection screen and running this report( we are developing an interface here... ) in which , depending on the selection screen values we retrieve the data from LIKP,LIPS tables and also some of the fields from CRM Sales order( this is where we have the current issue..) and send it to ( via proxy structure ) SAP PI which in turn creates a file with huge data.
So in this case we can't use BADI.
Hope it is clear now. If you need further details on the same,please let me know.
Thank you.
Regards
Anil
