Unexpected server error

One or more of the following validation rules failed:

• Invalid Coupa PO number
• Invalid UOM
• Invalid PO line number
• Missing cXML tags (e.g., IF creditMemo the original invoice #)
• If it's a Services PO then use Services tags
• Extra cXML tags that don't belong in an element or if the supplier is passing the "creditMemo" type, which is not supported in Coupa

How do I fix it?

Ensure that the following are valid:

• Coupa PO number (or Contract #)+UOM+PO line number
• IF "creditMemo" then original_invoice must be provided
