• What is the cause and solution for SAP error message WRF_APC228 - No reference store found. Scheduling not possible ?

  The SAP error message:
  WRF_APC228 No reference store found. Scheduling not possible
  typically occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Production Planning and Detailed Scheduling (PP/DS) or Supply Network Planning (SNP) modules.
  
  Cause
  This error indicates that the system cannot find a reference storage location (reference store) for the product or location combination during the scheduling or planning run. The reference store is essential because it defines the stock location from which the system should consider available inventory or where the product is stored for planning purposes.
  Common causes include:
  
  The product master data is incomplete or missing the assignment of a reference storage location.
  The location master data does not have a valid reference store defined.
  The integration between SAP ERP and APO is missing or incorrect for the relevant product/location.
  The planning area or product/location master data in APO is not maintained properly.
  The system is trying to schedule a product/location combination for which no reference store is defined in the planning model.
  
  
  Solution
  To resolve the error, follow these steps:
  
  
  Check Product Master Data:
  
  Verify that the product has a valid reference storage location assigned in the ERP system.
  In transaction MM02 (Change Material), check the Plant and Storage Location data.
  
  
  
  Check Location Master Data:
  
  Ensure that the location in APO has a reference store defined.
  In APO, use transaction /SAPAPO/LOC3 or the relevant location master data maintenance to verify the reference store.
  
  
  
  Check Integration and CIF Settings:
  
  Confirm that the product and location master data are correctly replicated from ERP to APO via CIF (Core Interface).
  Use transaction /SAPAPO/CIF_MON to monitor CIF queues and check for errors.
  Re-initialize or re-transfer master data if necessary.
  
  
  
  Maintain Reference Store in APO:
  
  In APO, assign the reference store to the product/location combination.
  This can be done in the product master data or location master data depending on the system setup.
  
  
  
  Check Planning Area and Heuristics:
  
  Verify that the planning area includes the relevant product/location combinations.
  Check if any heuristics or planning sequences require a reference store and adjust accordingly.
  
  
  
  Run Planning/Scheduling Again:
  
  After correcting the master data, rerun the scheduling or planning run.
