• What is the cause and solution for SAP error message /MOC/INTEGRATION034 - Objects of object type &1 are not allowed as the main reference object ?

  The SAP error message /MOC/INTEGRATION034 indicates that the system has encountered an issue where the specified object type (denoted by &1) is not permitted to be used as the main reference object in a particular context. This error typically arises in the context of SAP Master Data Governance (MDG) or similar integration scenarios where specific object types have defined roles and relationships.
  Cause:
  
  Invalid Object Type: The object type you are trying to use as the main reference object is not configured to be used in that capacity. This could be due to business rules or system configurations that restrict certain object types from being main reference objects.

  Data Model Restrictions: The data model in use may have specific restrictions on object types based on the business process or integration scenario.

  Use Alternative Object Types: If the object type cannot be changed or configured to be valid, consider using an alternative object type that is permitted as a main reference object in the context you are working with.
