• What is the cause and solution for SAP error message 61023 - A calculation of the number of partial lots is not possible ?

  The SAP error message 61023, which states "A calculation of the number of partial lots is not possible," typically occurs in the context of inventory management or production planning when the system is unable to determine how many partial lots can be created based on the available data. This can happen for various reasons, including issues with lot sizes, material availability, or configuration settings.
  Causes:
  
  
  Lot Size Configuration: The lot size settings for the material may not be configured correctly. If the system cannot determine how to split the total quantity into partial lots based on the defined lot sizes, this error can occur.
  
  
  Material Master Data: Incomplete or incorrect material master data can lead to this error. This includes missing information about the lot size, unit of measure, or other relevant fields.
  
  
  Production Order Issues: If you are working with production orders, there may be inconsistencies in the order quantities or the way the order is set up.
  
  
  Availability Check: The system may not be able to perform an availability check for the materials involved, leading to an inability to calculate partial lots.
  
  
  Batch Management: If batch management is enabled, issues with batch determination or batch characteristics can also lead to this error.
  
  
  Solutions:
  
  
  Check Lot Size Settings: Review the lot size settings in the material master (MM02) and ensure they are correctly defined. Make sure that the lot size is appropriate for the quantities you are working with.
  
  
  Review Material Master Data: Ensure that all relevant fields in the material master are filled out correctly, including the unit of measure, base unit of measure, and any other necessary data.
  
  
  Examine Production Orders: If applicable, check the production orders for any discrepancies in quantities or settings that might prevent the calculation of partial lots.
  
  
  Run Availability Check: Perform an availability check for the materials involved to ensure that there are no issues with stock levels or availability.
  
  
  Batch Management Settings: If batch management is in use, verify that the batch determination process is set up correctly and that there are no issues with batch characteristics.
