• What is the cause and solution for SAP error message WG303 - Selected plant must be a distribution center ?

  SAP Error Message:
  
  WG303 - Selected plant must be a distribution center
  
  Cause:
  This error occurs when you select a plant in a process or transaction that requires the plant to be defined as a Distribution Center (DC), but the selected plant is not set up as a distribution center in the system.
  In SAP, a Distribution Center is a special type of plant used in Warehouse Management (WM) and Logistics Execution (LE) processes. Certain transactions, especially those related to warehouse management, stock transfers, or delivery processing, require the plant to be flagged as a distribution center.
  
  Explanation:
  
  The system checks the plant master data to verify if the plant is configured as a distribution center.
  If the plant is not marked as a distribution center, the system throws the WG303 error.
  This is common in processes like creating warehouse tasks, transfer orders, or delivery documents where the plant must be linked to a warehouse.
  
  
  How to Check if a Plant is a Distribution Center:
  
  Go to transaction SPRO ? Logistics Execution ? Warehouse Management ? Master Data ? Define Distribution Centers.
  Or directly check the plant master data in transaction OX10 (Define Plants).
  Check if the plant is assigned to a warehouse number in Warehouse Management.
  Alternatively, check the table T001W (Plants/Branches) and see if the plant has a warehouse number assigned.
  
  
  Solution:
  
  
  Assign the Plant as a Distribution Center:
  
  Assign the plant to a warehouse number in Warehouse Management.
  Use transaction SPRO ? Logistics Execution ? Warehouse Management ? Master Data ? Assign Warehouse Number to Plant.
  Or use transaction OX09 to assign warehouse number to plant.
  
  
  
  Use a Correct Plant:
  
  If the process requires a distribution center, select a plant that is already configured as a distribution center.
  
  
  
  Check Warehouse Number Assignment:
  
  Ensure that the plant has a warehouse number assigned in the system.
  Without a warehouse number, the plant cannot act as a distribution center.
  
  
  
  If Warehouse Management is not used:
  
  If your business process does not use WM, check if the transaction or process is appropriate for the plant selected.
  
  
  
  
  Related Information:

  Summary:

  To fix, assign the plant to a warehouse number or select a plant that is already a distribution center.
  This is essential for warehouse-related processes in SAP Logistics Execution.
