• What is the cause and solution for SAP error message WPM_MSG_OFR_PRM_INTG121 - Missing transaction requirement quantity unit of measure ?

  The SAP error message:
  WPM_MSG_OFR_PRM_INTG121: Missing transaction requirement quantity unit of measure
  
  Cause:
  This error occurs when a transaction or process in SAP (often related to production planning, work process management, or order processing) requires a quantity unit of measure (UoM) for the transaction requirement, but this information is missing or not maintained.
  In other words, the system expects a unit of measure for the quantity involved in a transaction requirement (such as a production order component, process step, or work package), but it is not provided or not correctly determined.
  
  When does it typically occur?
  
  During creation or processing of production orders, process orders, or work packages.
  When integrating with Work Process Management (WPM) or related modules.
  When the system tries to calculate or validate quantities but cannot find the UoM.
  Possibly during confirmation, goods movement, or capacity planning steps.
  
  
  Solution:
  
  
  Check the Master Data:
  
  Verify that the material master record has a base unit of measure maintained.
  Check the Bill of Materials (BOM) and routing or process instructions to ensure that all components and operations have the correct quantity and unit of measure assigned.
  
  
  
  Maintain Unit of Measure in Transaction Requirement:
  
  Ensure that the transaction requirement or the relevant work package has a quantity unit of measure assigned.
  This might involve checking the configuration or customizing settings related to transaction requirements or work process management.
  
  
  
  Review Customizing Settings:
  
  In SPRO, check the settings for Work Process Management or Production Planning to ensure that the unit of measure determination is correctly set up.
  Verify if any user-exits or BAdIs are influencing the determination of UoM and correct them if necessary.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks on orders or work packages to identify missing or inconsistent data.
  Correct any missing UoM entries.
  
  
  
  Debugging / Logs:
  
  If the issue persists, use debugging or check application logs to identify where the UoM is expected but missing.
  This can help pinpoint whether the problem is in master data, configuration, or a custom enhancement.

  The error WPM_MSG_OFR_PRM_INTG121 indicates that the system cannot find the required unit of measure for a transaction requirement quantity. To resolve it, ensure that all relevant master data and configuration have the correct unit of measure maintained and that the transaction or process correctly references this data.
