• What is the cause and solution for SAP error message MA370 - Upper limit of lot size interval smaller than lower limit ?

  The SAP error message MA370, which states "Upper limit of lot size interval smaller than lower limit," typically occurs in the context of material management and production planning. This error indicates that there is a configuration issue with the lot size intervals defined for a material in the system.
  Cause:
  The error arises when the upper limit of a lot size interval is set to a value that is less than the lower limit. This creates a logical inconsistency because the upper limit should always be greater than or equal to the lower limit for the lot size intervals to function correctly.
  Solution:
  To resolve this error, you need to check and correct the lot size interval settings for the affected material. Here are the steps to do this:
  
  
  Access Material Master Data:
  
  Go to transaction code MM02 (Change Material) or MM03 (Display Material).
  Enter the material number and select the appropriate views (usually the "MRP" or "Purchasing" views).
  
  
  
  Check Lot Size Settings:
  
  Navigate to the "Lot Size" section within the MRP or Purchasing view.
  Review the defined lot size intervals. Look for any intervals where the upper limit is less than the lower limit.
  
  
  
  Adjust Lot Size Intervals:
  
  If you find any inconsistencies, adjust the values so that the upper limit is greater than or equal to the lower limit.
  For example, if you have an interval defined as 100 (lower limit) to 50 (upper limit), change the upper limit to a value greater than or equal to 100.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the changes to the material master data.
  
  
  
  Test the Changes:
