• What is the cause and solution for SAP error message MB106 - Key figure & already in info set ?

  The SAP error message MB106 ("Key figure & already in info set") typically occurs in the context of SAP's Material Management (MM) or Logistics Information System (LIS) when there is an attempt to create or modify an info structure (info set) that already contains a key figure with the same name. This can happen during the configuration of info structures for reporting purposes.
  Cause:
  
  Duplicate Key Figure: The error indicates that the key figure you are trying to add or modify already exists in the info structure. Each key figure in an info structure must have a unique name.
  Configuration Error: There may be a misconfiguration in the info structure setup, leading to attempts to add a key figure that is already defined.
  
  Solution:
  
  
  Check Existing Key Figures: 
  
  Go to the transaction code MC22 (Change Info Structure) or MC23 (Display Info Structure).
  Look for the info structure you are working with and check the list of key figures to see if the key figure you are trying to add already exists.
  
  
  
  Modify or Remove Duplicate:
  
  If the key figure already exists and you need to change it, consider modifying the existing key figure instead of adding a new one.
  If the key figure is not needed, you can remove it from the info structure.
  
  
  
  Use Unique Names: 
  
  If you need to create a new key figure, ensure that it has a unique name that does not conflict with existing key figures in the info structure.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help resources for guidelines on configuring info structures and key figures to avoid such conflicts.
