  The SAP error message MD601 ("Only total requirements with manual cost collectors are permitted") typically occurs in the context of Material Requirements Planning (MRP) when there is an attempt to process a requirement that does not meet the criteria for using manual cost collectors. This error is often related to the configuration of the MRP settings or the way the requirements are defined in the system.

  Manual Cost Collectors: The error indicates that the system is expecting a total requirement that is associated with a manual cost collector. If the requirement is not set up correctly or if it is not a total requirement, this error will occur.

  Requirement Type: The requirement type being used may not be compatible with manual cost collectors, leading to this error.
  
  Solution:
  
  Check Requirement Type: Ensure that the requirement type being used is compatible with manual cost collectors. You may need to adjust the requirement type settings in the configuration.
  Review Cost Collector Settings: Verify that the cost collectors are set up correctly in the system. This includes checking the configuration for manual cost collectors and ensuring that they are properly linked to the relevant requirements.
  Use Total Requirements: If you are trying to process a requirement that is not a total requirement, consider changing it to a total requirement if that aligns with your business processes.
  Consult Documentation: Review SAP documentation or help resources related to MRP and cost collectors to ensure that you are following the correct procedures.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on resolving it.

  Testing: After making changes, conduct tests to ensure that the error is resolved and that the MRP process functions as expected.
