Hi, we are using Dynamics connector for AX/CRM integration. It’s a bi-directional process, so we have two mapping one for CRM to AX and AX to CRM. CRM to AX : record is creating in CRM and flowing to AX though CRM to AX Map in connector. In Map , we mapped Integration key(CRM) with DAX Integration ID(AX) as Concatenate(“{“, Feature Request, “}”) AX to CRM :In Ax, updating the created record from CRM through AX to CRM Map and in Map we mapped DAX Integeration ID ,but in CRM its creating new record instead of updating the existing record in CRM with different Integration Key. Any help would be appreciated…!! Thanks, Sathish ---

Have you checked the log? Maybe something is being truncated or there’s no match for some reason. ---
