Ambigously Defined Sql

I am running the General Ledger -> Review Financial Information -> Ledger Inquiry in F92.  The auto constructed sql fails on an ambiguous definition of the dept for row security.

918 - ORA-00918: column ambiguously defined   is the trace message.

FROM PS_LEDGER A ,

  PS_SEC_DEPT_USER SCF1

.

.

.

.

OR DEPTID     IN

  (SELECT A1.DEPTID FROM PS_DEPTSEC02_VW A1 WHERE A1.OPRID='xxxxxx'

  ))

AND A.DEPTID       = SCF1.DEPTID

no qualifier is attached to the DEPTID.  Has anyone else seen this ?

thanks.
