Smart SAP Assistant

• What is the cause and solution for SAP error message /SAPAPO/ATP_BOP321 - Minimum bundle size is not smaller than the maximum bundle size ?

  The SAP error message /SAPAPO/ATP_BOP321 indicates that there is an issue with the bundle size configuration in the Advanced Planning and Optimization (APO) module, specifically in the Available-to-Promise (ATP) check. This error occurs when the minimum bundle size is set to a value that is not smaller than the maximum bundle size, which is logically incorrect.
  Cause:
  
  Configuration Error: The minimum bundle size and maximum bundle size are defined in the system settings. If the minimum bundle size is equal to or greater than the maximum bundle size, the system cannot process the request correctly.
  Data Entry Mistake: During the configuration of the product or during the creation of the planning object, incorrect values may have been entered for the bundle sizes.
  
  Solution:
  To resolve this error, you need to adjust the configuration settings for the bundle sizes. Here are the steps to do so:
  
  
  Access the Configuration:
  
  Go to the SAP Easy Access screen.
  Navigate to the relevant configuration area for the product or planning object where the error occurred.
  
  
  
  Check Bundle Size Settings:
  
  Look for the settings related to bundle sizes, which may be found under the product master data or in the configuration for the specific planning area.
  Verify the values for minimum and maximum bundle sizes.
  
  
  
  Adjust Values:
  
  Ensure that the minimum bundle size is set to a value that is strictly less than the maximum bundle size. For example, if the maximum bundle size is set to 100, the minimum bundle size should be set to a value less than 100 (e.g., 1 to 99).
  Save the changes.
  
  
  
  Test the Configuration:
  
  After making the adjustments, re-run the ATP check or the process that triggered the error to ensure that the issue has been resolved.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP documentation for detailed information on configuring bundle sizes in APO.
  Transaction Codes: You may need to use transaction codes like /SAPAPO/MAT1 (Product Master) or /SAPAPO/MC62 (Planning Book) to access and modify the relevant settings.
  Support: If the issue persists after making the necessary adjustments, consider reaching out to SAP support or consulting with a functional consultant who specializes in APO.
  
  By ensuring that the minimum bundle size is always less than the maximum bundle size, you can prevent this error from occurring in the future.
