C5864 - Details

• The SAP error message C5864 indicates that there is a problem with the uniqueness of a Process Instruction (PI) characteristic in the system. This error typically arises in the context of process orders or production orders when the system expects a unique combination of characteristics but finds duplicates.
  
  Cause:
  
  Duplicate Characteristics: The error usually occurs when there are multiple entries for the same PI characteristic in the system. This can happen if the same characteristic is assigned to multiple process instructions or if there are inconsistencies in the data.
  
  Configuration Issues: Incorrect configuration in the master data or process instruction setup can lead to this error.
  Data Migration Issues: If data has been migrated from another system or if there have been recent changes to the master data, it may result in duplicates.
  
  
  Solution:
  
  
  Check for Duplicates: 
  
  Go to the relevant transaction (e.g., CO02 for process orders) and check the characteristics assigned to the process instruction.
