Executing - "EGO_EXT_FWK_PUB"."Execution_Function" "ORA-06502: PL/SQL: numeric or value error"

Hi,

I've created a context sensitive DFF in Requisition Headers to be used in iProcurement.  To achieve this, I used the create item functionality in page personalization.  However, I am receiving this error - Executing - "EGO_EXT_FWK_PUB"."Execution_Function" "ORA-06502: PL/SQL: numeric or value error", when I save my work at the checkout summary page.

Your inputs are greatly appreciated.

Thanks,

Jack
