• What is the cause and solution for SAP error message WRF_DISPRO055 - Material &1, plant &2 were not calculated; entry contained in worklist ?

  SAP Error Message:
  
  WRF_DISPRO055 Material &1, plant &2 were not calculated; entry contained in worklist
  
  Meaning / Cause
  This message occurs during the availability check or requirements planning process in SAP (typically in PP or SD modules). It indicates that the material (Material &1) in the specified plant (&2) was not calculated because the system found an entry for this material and plant combination in the worklist.
  The worklist is a list of materials/plants that are scheduled for processing (e.g., planning run, availability check). If a material is already in the worklist, the system avoids recalculating it immediately to prevent redundant or conflicting calculations.
  In other words:
  
  The system detected that the material/plant is already queued for processing, so it skips recalculating it at this moment.
  
  When does this happen?
  
  During MRP runs or availability checks.
  When multiple transactions or processes try to calculate the same material/plant simultaneously.
  When a material is locked or scheduled for planning, and a new request tries to calculate it again.
  
  
  Solution / How to resolve
  
  
  Wait for the current planning run to complete:
  
  Since the material is already in the worklist, the system will process it shortly. No immediate action is needed unless the message persists.
  
  
  Check for stuck or long-running planning runs:  
  
  Use transaction MD04 or MD05 to check the status of the material's planning.
  Check if there are any background jobs (MRP runs) that are stuck or running too long.
  Use transaction SM37 to monitor background jobs related to MRP or availability check.
  
  
  
  Clear or reset the worklist if necessary:  
  
  Sometimes, the worklist entries may get stuck due to system errors or interruptions.
  You can use transaction MDVM (Worklist for MRP) to view and manage the worklist.
  If entries are stuck, you may need to delete or reset them carefully (consult your SAP Basis or PP consultant before doing this).
  
  
  
  Avoid simultaneous planning runs for the same material/plant:  
  
  Coordinate planning runs to prevent overlapping calculations.
  Use proper scheduling and locking mechanisms.
  
  
  
  Check for OSS Notes:  
  
  Sometimes SAP releases notes for specific issues related to worklist processing.
  Search SAP Support Portal for notes related to WRF_DISPRO055 or worklist processing issues.
  
  
  
  
  Related Information
  
  
  Worklist in MRP:
  
  The worklist is a queue that holds materials/plants to be processed during MRP runs. It helps optimize planning by grouping materials and avoiding duplicate calculations.
  
  
  Transactions to check worklist and planning:  
  
  MDVM - Display and manage MRP worklist  
  MD04 - Stock/Requirements List  
  MD05 - MRP List  
  SM37 - Job Monitoring
  
  
  
  Locking and buffering:
  
  The system uses locks and buffers to prevent simultaneous conflicting calculations. This message is part of that mechanism.
  
  
  
  Summary
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Material/plant is already in the MRP worklist, so system skips recalculation to avoid duplication.
  
  
  Effect
  Material & plant not calculated immediately; calculation deferred.
  
  
  Solution
  Wait for current processing to finish; check for stuck jobs; manage worklist via MDVM; avoid simultaneous runs.
