  The SAP error message /SAPAPO/OO_TR066 indicates that there is a configuration issue with the lot size settings for a product in the Advanced Planning and Optimization (APO) module. Specifically, it states that the minimum lot size is greater than the maximum lot size for the specified product. This inconsistency can lead to planning issues, as it is not logically possible to have a minimum requirement that exceeds the maximum allowable quantity.
  Cause:
  
  Configuration Error: The most common cause is an incorrect configuration in the product master data, specifically in the lot size settings.
  Data Entry Mistake: During the setup of the product, the values for minimum and maximum lot sizes may have been entered incorrectly.

  Review the values for "Minimum Lot Size" and "Maximum Lot Size".
  
  
  
  Correct the Values:
  
  Ensure that the minimum lot size is less than or equal to the maximum lot size. Adjust the values accordingly.
  For example, if the minimum lot size is set to 100 and the maximum lot size is set to 50, change the minimum lot size to a value that is less than or equal to 50.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the changes to the product master data.
