• What is the cause and solution for SAP error message CKMLWIP904 - The material ledger period status does not allow WIP determination ?

  The SAP error message CKMLWIP904 indicates that the material ledger period status does not allow for Work in Progress (WIP) determination. This typically occurs when the period for which you are trying to perform WIP calculations is either closed or not open for posting in the Material Ledger.
  Cause:
  
  Closed Period: The period you are trying to process is closed for postings in the Material Ledger.
  Period Status: The status of the material ledger period is set to "not open" for WIP determination.
  Configuration Issues: There may be configuration settings in the Material Ledger that restrict WIP calculations for certain periods.
  
  Solution:
  
  
  Check Period Status:
  
  Go to the transaction code MMPV (Close Periods) or MMPI (Open Periods) to check the status of the material ledger period.
  Ensure that the period you are trying to process is open for WIP determination.
  
  
  
  Open the Period:
  
  If the period is closed, you may need to open it. This can be done in the same transaction (MMPV or MMPI) by changing the status of the period to allow postings.
  
  
  
  Review Configuration:
  
  Check the configuration settings in the Material Ledger (transaction code OMX1 or OMX2) to ensure that the settings allow for WIP determination in the relevant periods.
  
  
  
  Consult with Finance Team:
  
  If you are unsure about opening a closed period, consult with your finance or controlling team to understand the implications of doing so.
  
  
  
  Run WIP Calculation:
  
  After ensuring the period is open, you can run the WIP calculation again using transaction code CKMLCP (WIP Calculation).
