• What is the cause and solution for SAP error message COM_IL013 - Relationship type & does not allow an object to be assigned to itself ?

  The SAP error message COM_IL013 indicates that there is an attempt to assign an object to itself in a relationship type that does not allow such an assignment. This typically occurs in the context of SAP's Classification and Object Management, particularly when dealing with object relationships in the SAP system.
  Cause:
  The error arises when you try to create or modify a relationship where the source and target objects are the same. For example, if you are trying to establish a relationship between a material and itself, the system will reject this action because the relationship type defined does not permit self-referencing.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Relationship Type: Review the configuration of the relationship type you are trying to use. Ensure that it is not set to disallow self-referencing. You can do this by navigating to the relevant customizing settings in the SAP system.
  
  
  Verify Object Assignment: Ensure that you are not mistakenly trying to assign the same object to itself. Double-check the object IDs or keys you are using in the assignment.
  
  
  Use Different Objects: If the relationship you are trying to create is valid, ensure that you are using different objects for the source and target in the relationship.
  
  
  Consult Documentation: If you are unsure about the relationship types and their configurations, refer to the SAP documentation or help resources for guidance on how to set up relationships correctly.
