• What is the cause and solution for SAP error message CF185 - Production resource/tool in use - Base unit of measure cannot be changed. ?

  The SAP error message CF185, "Production resource/tool in use - Base unit of measure cannot be changed," typically occurs when you attempt to change the base unit of measure for a production resource/tool (PRT) that is currently in use in a production order or another related process. This restriction is in place to maintain data integrity and ensure that ongoing processes are not disrupted by changes to fundamental attributes of the resources being used.
  Cause:
  
  Active Usage: The PRT is currently assigned to an active production order or is being used in a process.
  Data Integrity: Changing the base unit of measure while the PRT is in use could lead to inconsistencies in production data, inventory management, and reporting.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Usage: Verify if the PRT is currently assigned to any active production orders or processes. You can do this by checking the production orders or the relevant transactions where the PRT is utilized.
  
  
  Release or Complete Orders: If the PRT is in use, you may need to either:
  
  Wait until the production orders using the PRT are completed or released.
  If possible, remove the PRT from the active orders (this may require administrative permissions and should be done with caution).
  
  
  
  Change Base Unit of Measure: Once the PRT is no longer in use, you can proceed to change the base unit of measure. This can typically be done in the PRT master data (transaction code CR02 for changing the PRT).
  
  
  Reassign PRT: After changing the base unit of measure, you may need to reassign the PRT to any production orders or processes as necessary.
