I have enhanced the user exits EXIT_SAPLMEQUERY_001 & EXIT_SAPLMEQUERY_001 to display the purchase requisitions based on sales orders and WBS Elements (Work Break down structure).
For this I have created a new user group, Infoset and query with the new fields (Created a similiar one like the standard ABAP query MEBANF ).
And everything is working fine in ME21N , except I could not drag the document displayed and drop it into the next subscreen so that the PO can adopt the Purchase requistion. But when I use the Adopt button it is working fine.
Could somebody tell me where I was wrong?
Many thanks in advance.
