• What is the cause and solution for SAP error message REEXST212 - Set &1 contains itself as subobject (recursion) ?

  The SAP error message REEXST212 indicates that there is a recursion issue in the context of a set definition. Specifically, it means that a set (or a subset) is defined in such a way that it includes itself as a subobject, which is not allowed. This can happen in various contexts, such as when defining sets for reporting, selection criteria, or other data structures.
  Cause:
  The error occurs when:
  
  A set is defined to include itself directly or indirectly.
  There is a circular reference in the set definitions, where a set references another set that eventually leads back to the original set.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Set Definitions: Check the definition of the set that is causing the error. Look for any references that might lead back to the set itself.
  
  
  Modify Set Structure: If you find that the set includes itself, you will need to modify the structure of the set. Ensure that the set only includes valid subobjects that do not reference the set itself.
  
  
  Check for Indirect References: Sometimes, the recursion might not be direct. Check if there are other sets that reference the problematic set, creating an indirect loop.
  
  
  Test Changes: After making the necessary adjustments, test the set to ensure that the error no longer occurs.
  
  
  Documentation and Comments: If you are working in a team or if the sets are complex, document your changes and add comments to the set definitions to clarify the structure and avoid future issues.
