• What is the cause and solution for SAP error message /SAPAPO/SPPDRPSB050 - No Source of Supply Was Assigned ?

  The SAP error message /SAPAPO/SPPDRPSB050 No Source of Supply Was Assigned typically occurs in the context of Advanced Planning and Optimization (APO) when the system is unable to find a valid source of supply for a specific demand. This can happen in various scenarios, such as during the planning run, when trying to create a production order, or when executing a heuristic.
  Causes:
  
  Missing Master Data: The most common cause is that the master data for the source of supply (like vendors, production resources, or transportation lanes) is not properly maintained or is missing.
  Incorrect Planning Parameters: The planning parameters for the product or location may not be set correctly, leading to the system not being able to identify a valid source of supply.
  Stock Availability: There may be no stock available in the system for the product in question, or the stock may not be allocated to the relevant location.
  Planning Version Issues: The planning version being used may not have the necessary data or settings to identify a source of supply.
  Product Allocation: If product allocation is in place, it may restrict the availability of the product to certain sources of supply.
  Supply Chain Constraints: Constraints in the supply chain, such as capacity issues or transportation restrictions, may prevent the assignment of a source of supply.
  
  Solutions:
  
  Check Master Data: Ensure that all relevant master data (materials, vendors, production resources, etc.) is correctly maintained and active in the system.
  Review Planning Parameters: Verify the planning parameters for the product and location to ensure they are set correctly. This includes checking the sourcing strategy and any relevant settings in the product master.
  Stock Check: Check the stock levels for the product in question to ensure that there is sufficient stock available for allocation.
  Planning Version: Make sure you are using the correct planning version that contains the necessary data for the source of supply.
  Product Allocation Review: If product allocation is being used, review the allocation settings to ensure they are not overly restrictive.
  Run Heuristics or Planning Runs: After making the necessary adjustments, run the planning heuristics or planning runs again to see if the issue is resolved.
  Consult Logs and Messages: Check the logs and messages in the APO system for any additional information that may help diagnose the issue.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/SDP94 (for planning board) or /SAPAPO/MC90 (for checking master data) to investigate further.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  Documentation: Refer to SAP documentation for Advanced Planning and Optimization for more detailed information on master data setup and planning processes.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP APO for further assistance.
