Unable to create Purchasing document (BPA) for Negotiation processed through REQ

Content

We have created Requisition with Item Lines and processed it into Negotiation with BPA as outcome. After completing the award and trying to create purchasing document we keep on getting some error message and Negotiation goes into Purchasing Document creation Failed status.

Please advise the reasons why it is failing to create purchasing documents and how we can check the actually reason of issue , any where we can get those details which would be helpful to address it.

Thanks,

Rajesh M
