Hi Marc,
Thank you for reaching out to Microsoft community.
Please verify if the entity might have any disabled fields. During DMF exports, fields that are disabled due to a configuration key end up blocking export unless the export goes through staging. In this scenario the workaround is to edit the project field mappings to exclude the disabled config keys. A design improvement is scheduled for PU38 release.
Therefore, please remove the disabled fields from mapping and:
[1] Use staging table for exports to get past these kind of issues.
[2] If Skip staging = Yes, remove RevRecSalesDeliverNow and any other disabled fields from the mapping.
Please let me know if this helps or if you need any other information, and we will be more than glad to assist further. Also, kindly mark as verified if the answer is helpful.
If there is no helpful information, then please open a Support Ticket with Microsoft to get this investigated further.
With kind thoughts,
Laura
