• What is the cause and solution for SAP error message AJ471 - 'Last value' cannot be combined with proration or calculation of average ?

  The SAP error message AJ471, which states that "'Last value' cannot be combined with proration or calculation of average," typically occurs in the context of SAP's Controlling (CO) module, particularly when dealing with cost allocations or assessments.
  Cause:
  This error arises when you attempt to use the "Last value" method in conjunction with proration or average calculations in a cost allocation or assessment cycle. The "Last value" method is designed to take the last recorded value for a cost element, while proration and average calculations require a distribution of values over a period or a set of values, which is incompatible with the "Last value" approach.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Change the Allocation Method:
  
  If you are using the "Last value" method, consider switching to a different allocation method that is compatible with proration or average calculations. For example, you might use "Equal distribution" or "Summation" methods instead.
  
  
  
  Review the Configuration:
  
  Check the configuration settings in the allocation cycle. Ensure that the methods you are trying to use together are compatible. You may need to adjust the settings in the allocation cycle to avoid this conflict.
  
  
  
  Adjust the Cycle Settings:
  
  If you are using a cycle that includes both "Last value" and proration or average calculations, you may need to create separate cycles for different methods or adjust the existing cycle to ensure that only compatible methods are used together.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidance on allocation methods and their compatibility. This can provide insights into best practices and alternative approaches.
  
  
  
  Testing:
  
  After making changes, test the allocation cycle to ensure that the error no longer occurs and that the results are as expected.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context or fixes.
  Transaction Codes: Familiarize yourself with transaction codes related to cost allocation (e.g., KSU5 for assessment cycles, KSV5 for distribution cycles) to navigate and adjust settings effectively.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, providing insights or solutions from other users' experiences.
  
  By following these steps, you should be able to resolve the AJ471 error and successfully configure your cost allocation or assessment cycles in SAP.
