06621 - Details

• The SAP error message "06621 Unit of measure & cannot be used for simulation purposes" typically occurs when you are trying to use a unit of measure (UoM) in a context where it is not allowed for simulation purposes. This can happen in various transactions or processes, such as when performing simulations in production planning, material requirements planning, or other related modules.
  
  Cause:
  
  Incompatible Unit of Measure: The unit of measure you are trying to use is not defined for simulation purposes in the system. This could be due to configuration settings or the specific nature of the UoM.
  Master Data Issues: The material master data may not have the appropriate UoM settings for the simulation process you are attempting.
  Configuration Settings: The system configuration may restrict certain units of measure from being used in simulations.
  
  
  Solution:
  
  
  Check UoM Configuration:
  
  Go to the configuration settings in SAP (Transaction code: SPRO).
