• What is the cause and solution for SAP error message RSUOM129 - Check consistency of base unit of measure between &1 and &2 ?

  The SAP error message RSUOM129 indicates a consistency issue between the base unit of measure (UoM) of two different objects, typically between a material and its corresponding unit of measure in the system. This error often arises during operations such as material master data maintenance, inventory management, or when performing transactions that involve unit conversions.
  Cause:
  The error occurs when there is a mismatch in the base unit of measure between two related entities. For example:
  
  The base unit of measure defined in the material master does not match the base unit of measure defined in the related document (like a purchase order, sales order, or production order).
  There may be inconsistencies in the configuration of units of measure in the system, such as incorrect settings in the material master or in the unit of measure conversion tables.
  
  Solution:
  To resolve the RSUOM129 error, follow these steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the base unit of measure defined for the material.
  Ensure that the base unit of measure is correctly set and matches the expected value.
  
  
  
  Review Related Documents:
  
  Check any related documents (like purchase orders, sales orders, etc.) to see if they reference the correct base unit of measure.
  If there are discrepancies, you may need to adjust the documents or the material master accordingly.
  
  
  
  Unit of Measure Configuration:
  
  Verify the configuration of units of measure in the system. This can be done through transaction code OMT3E (for maintaining units of measure).
  Ensure that the conversion factors and relationships between different units of measure are correctly defined.
  
  
  
  Consistency Check:
  
  Use transaction code MM02 to make necessary changes to the material master if needed.
  After making changes, perform a consistency check to ensure that the base unit of measure is consistent across all relevant documents and master data.
  
  
  
  Reprocess Transactions:
  
  If the error occurred during a specific transaction, try to reprocess the transaction after making the necessary corrections.
