  Error Message
  VO212: UoM required to calculate the UoM load category
  
  Cause
  This error occurs when SAP tries to determine the load category based on the Unit of Measure (UoM) during production order processing or capacity planning, but the system does not have the necessary UoM information available.
  Specifically, the system needs a valid UoM to calculate the load category for capacity planning or scheduling purposes. If the UoM is missing or not maintained correctly in the relevant master data or transaction, SAP cannot perform the calculation and throws this error.
  Common scenarios causing this error:
  
  The Work Center or Routing does not have a valid UoM assigned for load calculation.
  The Activity Type or Operation in the routing lacks a UoM.
  The Material Master or production order item is missing the UoM required for load calculation.
