ERS PO cannot be detected in WFR

Hi All,

In WFR INI file is updated with the below configuration in PON section for ERS POs but still the PO which are self billed/ERS cannot be detected at WFR.

#ERS PO

PON_OP_StopERSPO=YES

PON_OP_StopERSPOInVerifier=YES

I trued to incorporate a code which will connect to the EBS DB to fetch the results for PO which are ERS and display the Error in WFR but getting the below script error:

Document processing interrupted due to script error.

Module 'Invoices', Event 'ValidateFieldInt', Field 'PONumber', Line 1418,Offset 0: (3265) Item cannot be found in the collection corresponding to the requested name or ordinal.
