Patch 16872531:R12.AP.B Causes Object OE_HEADER_PAYMENT_UTIL to Become Invalid

Hi,
We applied the patch 16872531:R12.AP.B and the OE_HEADER_PAYMENT_UTIL becomes invalid. The compilation error is:
SQL> alter package OE_HEADER_PAYMENT_UTIL compile body;
Warning: Package Body altered with compilation errors.
SQL> show errors;
Errors for PACKAGE BODY OE_HEADER_PAYMENT_UTIL:
LINE/COL ERROR
-------- -----------------------------------------------------------------
3494/13  PL/SQL: Statement ignored
3494/73  PLS-00302: component 'PAYMENT_PERCENTAGE' must be declared
