Issue: When exporting multiple Flat File transactions simultaneously in Transaction Manager, the following error is received:

'Unable to export transaction. Error: 'WriteXmlRow(): Token StartElement in state Epilog would result in an invalid XML document.''

Reason: The Flat File export is configured to use Single File mode, which attempts to combine multiple transactions into one file. When exporting multiple transactions at the same time, this causes an invalid XML structure — the system attempts to write additional records after the XML document has already been closed, resulting in this error.

Update the Flat File Options setting for the affected document type from Single File to Distinct Files within the Trading Partner's Transaction Setup.

Navigate: Transaction Manager → Trading Partners → (Select Trading Partner) → Transaction Setup

Select: The Export File Names tab

Locate: The affected document type under the Flat File Options column

Set: Change Single File → Distinct Files

Retry: Re-export your transactions

Alternatively, the Flat File Options setting can be updated at the Business System level under the Export File Type Names section.

Navigate: Transaction Manager → Business System → (Select Business System)

Locate: The Export File Type Names section

Find: The affected document type under the Flat File Options column

Set: Change Single File → Distinct Files

Retry: Re-export your transactions
