• What is the cause and solution for SAP error message WRF_APC084 - Unit of measure &1 does not exist ?

  The SAP error message:
  WRF_APC084 Unit of measure &1 does not exist
  Cause:
  This error occurs when the system cannot find the specified unit of measure (UoM) in the SAP system during a process related to Advanced Planning and Optimization (APO) or related modules. The placeholder &1 is replaced by the actual unit of measure code that the system is trying to validate.
  Common scenarios causing this error include:
  
  The unit of measure used in a master data record (e.g., product, BOM, or production order) is not defined in the system.
  The unit of measure is missing in the relevant customizing or master data.
  Data inconsistencies between SAP ERP and SAP APO systems, especially if CIF (Core Interface) is used for data transfer.
  Incorrect or incomplete data upload or migration.
  
  Solution:
  
  
  Check the Unit of Measure in SAP ERP:
  
  Go to transaction CUNI (Units of Measure) and verify if the unit of measure exists.
  If it does not exist, create the unit of measure with the correct details.
  
  
  
  Check Master Data:
  
  Verify the unit of measure assigned to the material master (MM03) or other relevant master data.
  Ensure that the unit of measure is consistent and valid.
  
  
  
  Check CIF Integration (if applicable):
  
  If the error occurs during CIF data transfer between SAP ERP and APO, check the CIF logs (transaction CIFMON or /SAPAPO/CIFMON).
  Ensure that the unit of measure is correctly mapped and exists in both systems.
  Re-transfer the master data if necessary.
  
  
  
  Customizing and Configuration:
  
  Check if the unit of measure is maintained in the relevant customizing paths, especially if the process involves special units or conversions.
  For APO, check unit of measure settings in transaction /SAPAPO/UMC.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks for master data and units of measure.
  Correct any discrepancies found.
  
  
  
  Transport and System Landscape:
  
  If the unit of measure was recently created or changed, ensure that the changes are transported properly across the system landscape.
