• What is the cause and solution for SAP error message MB084 - Key figure & exists already ?

  The SAP error message MB084 ("Key figure & exists already") typically occurs in the context of inventory management or material management when there is an attempt to create or update a key figure that already exists in the system. This can happen in various scenarios, such as during the posting of goods movements, inventory adjustments, or when working with material master data.
  Cause:
  
  Duplicate Key Figure: The error indicates that the key figure you are trying to create or modify already exists in the database. This could be due to a previous transaction that created the key figure or an attempt to re-enter data that has already been processed.

  Data Validation: Implement data validation checks in your processes to prevent duplicate entries. This can include checks in user exits or BAdIs (Business Add-Ins) to ensure that the key figure does not already exist before attempting to create it.
  Consult Documentation: Review SAP documentation or help resources for specific guidance related to the transaction or process you are working with. This can provide insights into how to handle key figures correctly.
