• What is the cause and solution for SAP error message /SAPAPO/OPT020 - Priorities must be entered in ascending order ?

  The SAP error message /SAPAPO/OPT020 indicates that there is an issue with the priority settings in the Advanced Planning and Optimization (APO) module of SAP. Specifically, this error occurs when the priorities assigned to the planning objects (like production orders, purchase orders, etc.) are not in ascending order. In other words, the system expects the priorities to be listed from the lowest number (highest priority) to the highest number (lowest priority).
  Cause:
  
  Incorrect Priority Assignment: The priorities assigned to the planning objects are not in the expected ascending order. For example, if you have priorities 1, 3, and 2, the system will throw this error because 2 is not in the correct order.
  Data Entry Error: During data entry or configuration, priorities may have been assigned incorrectly.
  Configuration Issues: There may be issues in the configuration of the planning area or the way priorities are defined in the system.
  
  Solution:
  
  Check Priority Assignment: Review the priorities assigned to the planning objects. Ensure that they are in ascending order. For example, if you have priorities 1, 2, and 3, they are correctly ordered.
  Reassign Priorities: If you find any priorities that are out of order, reassign them to ensure they follow the ascending order requirement.
  Data Validation: Implement data validation checks to prevent incorrect priority assignments in the future.
  Consult Documentation: Refer to the SAP documentation or help files for guidance on how to properly assign priorities in your specific APO configuration.
  Testing: After making changes, test the planning run again to ensure that the error is resolved.
