I assume you mean Datasource. TIBOQuery doesn't have a Mastersource property.

A few things:

1. Make sure the SP actually is a selectable procedure. If it
doesn't return its output via a SUSPEND statement, it's not a
selectable procedure.

2. What's the actual fieldname of the linking key? Is it ItemRef or
"ItemRef"? They're not the same.

3. Is ItemRef in the master a unique key? The M/D linkage will be
garbled if it's not.

4. And I suppose this should be the first check: have you actually
tested the SP independently, with parameters, to see whether it
returns the output you expect?
