• What is the cause and solution for SAP error message /SAPAPO/SRC004 - No source of supply for in-house production ?

  The SAP error message /SAPAPO/SRC004 No source of supply for in-house production 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 product that is planned for in-house production. This can happen for various reasons, and understanding the cause is crucial for resolving the issue.
  Causes:
  
  
  Missing or Incorrect Master Data:
  
  The material master data may not be set up correctly. This includes missing production resources, incorrect planning strategies, or incorrect production versions.
  The production version may not be assigned to the material.
  
  
  
  No Valid Production Orders:
  
  There may be no active production orders for the material in question, or the existing orders may not be valid for the planning period.
  
  
  
  Capacity Constraints:
  
  The production resources may be fully booked or have capacity constraints that prevent the creation of new production orders.
  
  
  
  Planning Parameters:
  
  The planning parameters for the material may not be set correctly, such as lead times, lot sizes, or safety stock levels.
  
  
  
  Location Issues:
  
  The location (plant) where the production is supposed to occur may not be set up correctly in the system, or it may not have the necessary resources.
  
  
  
  Solutions:
  
  
  Check Master Data:
  
  Verify that the material master data is complete and accurate. Ensure that the production version is assigned and that the necessary production resources are available.
  
  
  
  Review Production Orders:
  
  Check if there are any active production orders for the material. If not, create a new production order if needed.
  
  
  
  Analyze Capacity:
  
  Review the capacity of the production resources. If they are fully booked, consider rescheduling or adjusting the production plan.
  
  
  
  Adjust Planning Parameters:
  
  Review and adjust the planning parameters for the material, including lead times, lot sizes, and safety stock levels.
  
  
  
  Check Location Settings:
  
  Ensure that the plant and location settings are correct and that the necessary resources are available at the specified location.
  
  
  
  Run the Heuristic or Optimization:
  
  If applicable, run the relevant heuristic or optimization process in APO to generate a new production plan that considers the available sources of supply.
  
  
  
  Related Information:
