• What is the cause and solution for SAP error message /SAPAPO/CTM1268 - In-house production source of supply &1 has been selected already ?

  The SAP error message /SAPAPO/CTM1268 indicates that an in-house production source of supply has already been selected for a particular planning situation. This typically occurs in the context of Advanced Planning and Optimization (APO) when using the Capable-to-Match (CTM) functionality.
  Cause:
  The error is triggered when the system attempts to assign a production source to a demand that has already been assigned to another production source. This can happen due to:
  
  Duplicate Planning: The same demand is being planned multiple times, leading to conflicts in source assignment.
  Configuration Issues: The settings in the planning area or the production resources may not be configured correctly, leading to overlapping assignments.
  Resource Constraints: The production resource may have constraints that prevent it from being assigned to multiple demands simultaneously.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Demand Assignment: Review the demand that is causing the error and check if it has already been assigned to a production source. You can do this by analyzing the planning results in the CTM or by checking the relevant planning books.
  
  
  Adjust Planning Parameters: If the demand is indeed assigned, you may need to adjust the planning parameters or the production schedule to allow for the correct assignment of sources.
  
  
  Review Resource Availability: Ensure that the production resources are available and not over-allocated. You may need to adjust the production schedule or resource allocation to resolve conflicts.
  
  
  Use Alternative Sources: If the in-house production source is already selected, consider using alternative sources of supply if available. This may involve changing the planning strategy or modifying the source selection criteria.
  
  
  Check Configuration: Review the configuration settings in the APO system related to the planning area, production resources, and source selection. Ensure that they are set up correctly to avoid conflicts.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the CTM functionality for any specific guidelines or updates that may address this issue.
