• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED122 - EDM name '&1' already in use by property ?

  The SAP error message /IWBEP/CM_V4_MED122 indicates that there is a conflict with the EDM (Entity Data Model) name in your OData service. Specifically, it means that the EDM name you are trying to use (represented by &1) is already in use by another property in your OData model. This can happen when you have multiple properties or entities that are trying to use the same name, which is not allowed in the context of OData services.
  Cause:
  
  Duplicate Names: The most common cause is that you have defined two or more properties or entities with the same name in your OData model.
  Model Conflicts: If you are importing or merging multiple models, there may be conflicts in naming.
  Changes in the Model: If you have recently modified the model (e.g., added or renamed properties), it may lead to conflicts if the changes are not properly reflected.
  
  Solution:
  
  Check for Duplicates: Review your OData model definition to identify any duplicate property names. Ensure that each property and entity has a unique name.
  Rename Properties: If you find duplicates, rename the conflicting properties or entities to ensure uniqueness.
  Regenerate the Model: After making changes, regenerate the OData service to ensure that the changes are reflected in the service definition.
  Clear Cache: Sometimes, cached versions of the model can cause issues. Clear any relevant caches in your SAP system.
  Check Annotations: If you are using annotations, ensure that they do not conflict with the property names in your model.
  
  Related Information:
  
  OData Service Definition: Familiarize yourself with the OData service definition and how properties and entities are structured.
  SAP Gateway: If you are using SAP Gateway, check the transaction /IWFND/MAINT_SERVICE to manage your OData services.
  Debugging: Use debugging tools in SAP to trace where the conflict is occurring if the error message does not provide enough context.
  Documentation: Refer to SAP documentation on OData services and the Entity Data Model for best practices in naming conventions and model design.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
