Preview unadded documents in Crystal

The Generic SAP system layouts appear to work when previewing unadded documents. Mine work for drafts, but not unadded documents.

The system ones use a stored procedure, so I have updated my reports and inserted the same stored procedure in my layouts and created the same joins and record selections, but when I try to preview any documents using these layouts I am asked for @dockey@ and @objectid@, being the parameters introduced from the stored proc edure.

What am I missing ?

Thanks
