Posted on by Sina Khodaparast 25

I have Entity "A" and Entity "B" with a 1:N relationship from A to B and on both Entities I have a Customer Lookup Field. (The new type at CRM 2016)

I create a new field Mapping between these fields without any problem.But when I want to Add a new record of Entity B from Entity A the mapping is not working and it gives me "Invalid Argument" Error with the following details:

    Hi Tom,

    Yes,That is my case. I think that's a bug,too.

    I am trying to map the customer field from Entity A to customer field on Entity B.

    Hi Sina, sorry I misunderstood.

    This may be a bug, as I have come across this before. I cannot map fields that are part of a "customer" type field. For instance if I have an account field on an opportunity, I cannot create mappings for that account field, because account is used in parentaccountid as part of the OOB customer field.

    I would guess same is happening here for you. Are you trying to adjust Mapping on the 1:N between A and B, or on the customer field on each?

    Hi Sina,

     honestly, if it's version-specific then, unless somebody here ran into it on exactly the same version.. it might be a good reason to contact MS support. But yes, it did work for me in the online trial environment.

    Dear Alex

    I have the problem at Microsoft Dynamics CRM 2016 Service Pack 1 (on-premises). It would be a good news if this error had been solved in the newer versions.

    And this error can happen for any entity that has been customized by adding the Customer field.

    Hi Tom

    Thanks for the reply. I have a customer field on entity A, which in fact is two lookup fields to Account and Contact Entities. And I have the same customer field on Entity B. You can read more about the customer field which is a new Capability added since CRM 2016 update 1 at the following post:

    https://community.dynamics.com/crm/b/crmandunifiedservicedesk/archive/2016/06/13/crm-2016-update-1-customer-field

    so here, there is no need to the third entity.

    My problem is at mapping customer field from customer of Entity A to customer of Entity B.

    This seems to be working just fine in the online trial (which is 8.2).

    That error, though, can probably happen for various reasons.. I'm wondering if, in your example, it's happening for any two entities if you map customer fields between them, or if it's only happening for those particular entities A and B.

    Hi Sina, thanks for reaching out.

    I could be wrong but the Customer type field requires three entities, what is the third entity? The purpose is that entity C has a 1:N to both A and B, which are interchangeable, but always one or the other, and now with customer field type you can have only one field represent the two entities. Otherwise it is just a lookup from B to A which creates the 1:N relationship on A and allows you to add Entity B to Entity A.  

    The system is trying to populate entity C but that is missing (null). Let me know how to help.
