"Cannot create property;entity for association does not exist"


SAP Cloud for Customer

Reproducing the Issue

  1. Go to Administrator work center
  2. Select the OData Service Explorer view
  3. Select the service C4CODataapi service
  4. Select the custom field from the list of entity types




BO attributes from 0..n associations(in this case COMMON node) cannot be merged to existing entity types.

Only new entity types can be created in such cases.

Also, a new entity type creation is not possible for standard associations via PDI.

However, attributes from 0..1 associations can be merged.


Use CurrentCommon association. Attributes from 0..1 associations (in this case CurrentCommon) can be merged.

You have to extend the 0..n associations node, but same attribute will also be available via  0..1 association as well.
