• What is the cause and solution for SAP error message CMS_REL004 - Reversible relationships are not supported in the system ?

  The SAP error message CMS_REL004 indicates that reversible relationships are not supported in the system. This error typically arises in the context of the SAP Customer Management System (CMS) when attempting to create or manage relationships between business partners (BPs) or other entities that are defined as reversible.
  Cause:
  The error is caused by the attempt to create a relationship that is defined as reversible, which the system does not support. In SAP, relationships can be defined as either one-way or reversible. A reversible relationship implies that if A is related to B, then B is automatically related to A. However, certain configurations or system settings may not allow for this type of relationship.
  Solution:
  To resolve the CMS_REL004 error, consider the following steps:
  
  
  Check Relationship Type: Review the type of relationship you are trying to create. Ensure that it is defined as a one-way relationship if the system does not support reversible relationships.
  
  
  Modify Relationship Settings: If you need a reversible relationship, check the configuration settings in the system. You may need to adjust the relationship type in the customizing settings (transaction code SPRO) under the relevant area for business partner relationships.
  
  
  Consult Documentation: Refer to the SAP documentation or help files related to business partner relationships to understand the limitations and configurations available for your version of SAP.
  
  
  System Configuration: If you have access to system configuration, ensure that the necessary settings for relationships are correctly configured. This may involve working with your SAP Basis or technical team.
  
  
  SAP Notes and Support: Check for any relevant SAP Notes that may address this issue. Sometimes, specific patches or updates may resolve known issues related to relationship management.
