Patch 18724731:R12.PO.B: invalidates PO_CHG_REQUEST_PVT

The patch has been applied but it invalidated one of the PO package bodies: PO_CHG_REQUEST_PVT.

When the DBA tried to compile the PO_CHG_REQUEST_PVT package body, the error we are getting is:

SQL> alter package po_chg_request_pvt compile body;

Warning: Package Body altered with compilation errors.

SQL> show errors
Errors for PACKAGE BODY PO_CHG_REQUEST_PVT:

LINE/COL ERROR
-------- -----------------------------------------------------------------
1017/5 PL/SQL: Statement ignored
1017/5 PLS-00313: 'IS_ASN_EXIST' not declared in this scope
SQL>

Please helps

Thanks
