• What is the cause and solution for SAP error message /SAPAPO/CTM1379 - Maximum lot size for source of supply &1 is lower than standard value ?

  The SAP error message /SAPAPO/CTM1379 indicates that the maximum lot size defined for a source of supply is lower than the standard value that is being used in the planning process. This typically occurs in the context of Advanced Planning and Optimization (APO) when using the Capable-to-Match (CTM) planning method.
  Cause:
  
  Configuration Issue: The maximum lot size for the source of supply (e.g., a vendor or production location) is set lower than the standard lot size required for the production or procurement process.
  Master Data Settings: The settings in the material master or the source of supply master data may not align with the requirements of the planning run.
  Planning Parameters: The planning parameters defined in the APO system may not be consistent with the operational constraints of the supply chain.
  
  Solution:
  
  
  Review Maximum Lot Size: Check the maximum lot size defined for the source of supply in the material master or the source of supply master data. Ensure that it is set appropriately to meet the planning requirements.
  
  Navigate to the material master data in SAP and check the relevant views (e.g., MRP view).
  Adjust the maximum lot size if necessary.
  
  
  
  Adjust Standard Lot Size: If the maximum lot size is correct and should remain lower, consider adjusting the standard lot size in the planning parameters to align with the maximum lot size.
  
  This can be done in the APO system under the relevant planning settings.
  
  
  
  Check Planning Strategy: Review the planning strategy being used for the material. Ensure that it is appropriate for the supply chain and that it aligns with the lot size settings.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring lot sizes and planning parameters.
  
  
  Testing: After making adjustments, run a test planning run to ensure that the error does not reoccur and that the planning results are as expected.
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional insights into lot size configurations.
