• What is the cause and solution for SAP error message UJA_EXCEPTION120 - Model ID &1 already exists ?

  The SAP error message UJA_EXCEPTION120 indicates that there is an attempt to create or import a model with an ID that already exists in the system. This typically occurs in the context of SAP Business Planning and Consolidation (BPC) or SAP BW (Business Warehouse) when dealing with planning models or data models.
  Cause:
  
  Duplicate Model ID: The most common cause is that the model ID you are trying to create or import is already present in the system. This can happen if:
  
  You are trying to create a new model with an ID that has already been used.
  There was a previous import or creation process that did not complete successfully, leaving the model ID in the system.
  You are working in a development environment where the same model ID is being used across different transports.
  
  
  
  Solution:
  
  
  Check Existing Models: 
  
  Go to the relevant transaction or application where models are managed (e.g., BPC, BW).
  Look for the model ID in question to confirm that it already exists.
  
  
  
  Use a Different Model ID: 
  
  If the model ID is indeed taken, consider using a different, unique model ID for your new model.
  
  
  
  Delete or Modify Existing Model: 
  
  If the existing model is no longer needed, you can delete it. Ensure that you have the necessary authorizations and that deleting the model will not affect other processes.
  If the existing model needs to be modified, you can update it instead of creating a new one.
  
  
  
  Check for Incomplete Processes: 
  
  If you suspect that a previous process left the model in an incomplete state, check for any ongoing processes or transactions that might be locking the model.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to model management in your specific version of SAP to ensure you are following best practices.
  
  
  
  Contact SAP Support: 
  
  If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is impacting production environments.
