  Check Load Building Requirements: Ensure that there are items available for load building. If there are no items to load, the process will not be required.
  Review Configuration: Verify the configuration settings for load building in the system. Ensure that the range of coverage algorithm is correctly set up and activated.
  Data Validation: Check the data being used for load building. Ensure that all necessary information (quantities, item details, storage locations) is complete and accurate.
  Test with Different Scenarios: If possible, test the load building process with different sets of data to see if the issue persists. This can help identify if the problem is data-specific.
  Consult Documentation: Review SAP documentation or notes related to load building and the specific algorithm being used to ensure that all prerequisites are met.
