W0022 - Details

• SAP Error Message:
  W0022 - A reference plant already exists for stores
  
  
  Cause:
  This warning message occurs when you try to assign or create a reference plant for a storage location, but the system detects that a reference plant has already been assigned to that storage location. In SAP, a storage location can only have one reference plant assigned to it. The reference plant is used in inventory management and procurement processes to link the storage location to a specific plant for valuation and stock management purposes.
  
  Explanation:
  
  Reference Plant: A plant that is linked to a storage location for valuation and stock management.
  Storage Location: A subdivision of a plant where inventory is physically stored.
  When you try to assign a reference plant to a storage location that already has one, SAP raises this warning to prevent duplicate or conflicting assignments.
