• What is the cause and solution for SAP error message /SAPAPO/RBA119 - Base units of measure of the products are NOT the same ?

  The SAP error message /SAPAPO/RBA119 indicates that there is a mismatch in the base units of measure for the products involved in a particular operation, such as a planning run or a transaction in SAP Advanced Planning and Optimization (APO). This error typically arises when you are trying to perform operations that require products to have the same base unit of measure, such as during the creation of a planning order or when aggregating data.
  Cause:
  
  Different Base Units of Measure: The products being processed have different base units of measure defined in their material master records. For example, one product might be measured in kilograms while another is measured in grams.
  Configuration Issues: There may be configuration issues in the system that lead to incorrect unit of measure settings.
  Data Entry Errors: Incorrect data entry during the creation or maintenance of material master records can lead to discrepancies in units of measure.
  
  Solution:
  
  
  Check Material Master Records:
  
  Go to the material master records for the products involved and verify their base units of measure.
  Ensure that the base units of measure are consistent for the products you are trying to process together.
  
  
  
  Adjust Base Units of Measure:
  
  If the base units of measure are different and they need to be the same for the operation, you may need to change the base unit of measure for one of the products. This can be done in the material master (transaction code MM02).
  Be cautious when changing the base unit of measure, as it may affect existing stock and transactions.
  
  
  
  Review Configuration:
  
  Check the configuration settings in the system to ensure that the units of measure are set up correctly. This may involve reviewing the settings in the SAP IMG (Implementation Guide).
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed guidance on handling units of measure in APO.
  
  
  
  Testing:
