• What is the cause and solution for SAP error message RU190 - Individual cap. &/& is already manually confirmed ?

  The SAP error message RU190, which states "Individual capacity &/& is already manually confirmed," typically occurs in the context of capacity planning and scheduling in SAP, particularly when dealing with production orders or capacity requirements.
  Cause:
  This error arises when you attempt to confirm a capacity that has already been manually confirmed. In SAP, individual capacities (like work centers or production resources) can only be confirmed once for a specific time period. If a confirmation is attempted again for the same capacity within that time frame, the system will generate this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Confirmations: 
  
  Use transaction codes like CO11N (for confirming production orders) or COHV (for mass processing of confirmations) to check if the capacity has already been confirmed.
  Review the confirmation history for the specific work center or resource to see if there are overlapping confirmations.
  
  
  
  Adjust Confirmations:
  
  If you find that the capacity has been confirmed, you may need to adjust or delete the existing confirmation if it is incorrect or no longer needed.
  Use transaction CO13 to reverse a confirmation if necessary.
  
  
  
  Review Scheduling:
  
  Ensure that the scheduling of production orders or operations does not overlap in a way that would cause multiple confirmations for the same capacity.
  Adjust the scheduling parameters or the production order to avoid conflicts.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to capacity planning and confirmations for additional insights and best practices.
