When using primary contract in field mapping, creating or updating accounts do not work.
Workaround is available by switching to complex mapping.
The following message can be seen from the entitlement screen:
"Could not execute the mapping for field Department for person . Ambiguous match found."
Mapping preview says:
"Error: Ambiguous match found."
