• What is the cause and solution for SAP error message CRM_BSP_PROD158 - Relationship type & does not allow an object to be assigned to itself ?

  The SAP error message "CRM_BSP_PROD158: Relationship type & does not allow an object to be assigned to itself" typically occurs in the context of SAP Customer Relationship Management (CRM) when you are trying to create or modify a relationship between objects (such as business partners, products, or other entities) and the system detects that you are attempting to assign an object to itself.
  Cause:
  The error is caused by the following reasons:
  
  Self-Assignment: You are trying to create a relationship where the source and target objects are the same. For example, if you are trying to assign a business partner to itself, the system will not allow this because it violates the relationship rules defined in the system.
  Relationship Type Restrictions: The specific relationship type you are using has been configured to disallow self-assignments. This is a common restriction in many relationship types to maintain data integrity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  Check Object IDs: Ensure that you are not mistakenly using the same object ID for both the source and target in the relationship. Verify that you are using different objects.
  Review Relationship Type Configuration: If you have access to the configuration settings, check the relationship type settings in the SAP CRM customizing (transaction code SPRO). Look for the specific relationship type and see if it has been configured to allow self-assignments. If necessary, you may need to adjust the configuration, but this should be done with caution and ideally by someone with appropriate authorization and understanding of the implications.
  Use Different Objects: If you need to create a relationship, ensure that you are using different objects that are valid for the relationship type you are working with.
  Consult Documentation: Review the SAP documentation or help resources related to the specific relationship type you are working with to understand its constraints and requirements.
  
  Related Information:
  
  Transaction Codes: You may find it useful to use transaction codes like BP (Business Partner) or CRMD_ORDER (for CRM orders) to navigate and check the relationships.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  User Authorization: Ensure that you have the necessary authorizations to create or modify relationships in the system, as restrictions may also be related to user permissions.
  
  If the issue persists after following these steps, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
