Not able to add requistion line to a draft RFQ if template is applied

Hello,

In eBS 12.2.6, i get the following error if i try to use the document builder to add a requisition line to a draft RFQ on which i applied a template :

oracle.apps.fnd.framework.OAException: java.sql.SQLException: ORA-01086: savepoint 'CREATE_NEGOTIATION_BULK_SP' never established in this session or is invalid
ORA-06512: at "APPS.PO_NEGOTIATIONS_SV1", line 167
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at line 1

I followed note 1439630.1, but that doesn't solve the issue and found nothing in My Oracle Support.

Replication steps :

1 ) create a RFQ template
2 ) Create New RFQ , apply the template and save draft negotiation
