Forum Post: CRM to NAV map using Entry No. as Primary Key with Connector

In regards to the CRM Connector for Dynamics NAV:

On a CRM to NAV map it seems that the primary key on the NAV table cannot be an Entry No. (integer).  I get the following error:

[Contact to NAV CRM Contact] has encountered an error while processing key [[Nate Boyd, 1335117f-d58c-e211-9301-00155d015a02]]. You cannot change the value of an AutoIncrement field. Field: Entry No. Table: CRM Contacts Identification fields and values: Entry No.='139659'

I have tried with the Entry No. property AutoIncrement = true and I tried with code on the OnInsert trigger that assigns the Entry No.  Get the same error.

The error message indicates that it is inserting the record and then trying to insert it again.  Has anyone been able to get a similar map successfully working?
