• What is the cause and solution for SAP error message /SAPAPO/CTM1397 - Location product &1/&2 is also main receipt of source of supply &3 ?

  The SAP error message /SAPAPO/CTM1397 indicates that there is a conflict in the configuration of a location product in the Advanced Planning and Optimization (APO) module, specifically in the context of the Capable-to-Match (CTM) planning process. The error message states that the location product (identified by &1 and &2) is also the main receipt of a source of supply (identified by &3). This typically occurs when the system is trying to plan or allocate resources, but the configuration does not allow for the specified setup.
  Cause:
  
  Main Receipt Conflict: The location product is set as a main receipt for a source of supply, which means it is expected to receive products from that source. However, the same location product is also being treated as a source of supply for another product, leading to a conflict in the planning logic.
  Incorrect Master Data Configuration: The master data for the location product or the source of supply may not be set up correctly, leading to this conflict.
  Planning Parameters: The planning parameters or settings in the CTM configuration may not be aligned with the intended supply chain design.
  
  Solution:
  
  Review Master Data: Check the master data for the location product and the source of supply. Ensure that the location product is not incorrectly set as both a source of supply and a main receipt for the same source.
  Adjust Planning Parameters: Review the CTM planning parameters and settings. Make sure that the configuration allows for the intended flow of goods and does not create circular dependencies.
  Change Receipt Assignment: If necessary, change the assignment of the main receipt for the source of supply to another location product that does not conflict with the current setup.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on configuring location products and sources of supply in CTM.
  Testing: After making changes, run a test planning run to ensure that the error does not reoccur and that the planning logic works as intended.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on configuration.

  Training and Documentation: Consider training sessions or documentation on SAP APO and CTM to better understand the planning processes and how to manage master data effectively.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP APO expert or reach out to SAP support for further assistance.
