I was trying to create a link b/w custom entity(PK) and "service entity", so i was trying to create a field (Foreign Key of custom entity) in service entity.
I am not able to create a field in service entity as it is not allowing me to customize.
I Wanted to know weather i can create a custom field in service entity ? Is there a way to create a custom field ?
I am using Microsoft dynamics CRM online instance.
Thanks in Advance.
No, it is not possible to create custom fields in the service entity.
From EntityMetadata.xlsx in the SDK you can see the following values:
This confirms your observation and shows that it is only possible to create 1:N-relationships from the service entity (not N:1-relationships, N:N-relationships or fields).
