Inserting code in Infoset query

[Former Member]

Hi Experts,

I have a infoset ZFI_REV_VAT and a infoset query created for it ZAQ_FIREV_VAT.

I need to insert logic to check for security authorization.

i know the ABAP code which need to be written but don't know where to write the code.

I can not modify the code through SE38 as the query program is Standard one.

Can you please suggest where and how do i insert the code.

Thanks

I got the hint that i can insert code in Code section of info set through tcode SQ02.

Please confirm

I want to add the code on event "At SELECTIOn-SCREEN" but this event seems to be disabled means when coding section

"At selection screen" it goes back to "DATA" section.

Can you please tell me how can i enable "At selection screen event" and write the code.

Thanks
