Dear Sonia,
The PR release date can be taken from table CDPOS.
use SE16N and take CDPOS table. Enter CDPOS-OBJECTID= EBAN-BANFN
But make sure the length of PR number should be 10. If PR number is having length 9 then put one Zero (0) ahead.
Now, Put CDPOS-OBJECTCLAS= BANF AND CDPOS-FNAME= FRGZU
NOW GET CDPOS-CHANGENR AND PASS THIS NUMBER INTO CDHDR-CHANGENR TABLE
FETCH HERE CDHDR-UDATE (LATEST).
Please appreciate if it works
Thanks & Regards,
Rakesh
