• What is the cause and solution for SAP error message CM_EHFND_FW_CALC_ENG134 - Usage of "&1" more than once in an aggregation function is not permitted ?

  The SAP error message CM_EHFND_FW_CALC_ENG134 indicates that there is an issue with the usage of an aggregation function in your calculation logic. Specifically, it states that the variable or field represented by "&1" is being used more than once within the same aggregation function, which is not allowed.
  Cause:
  This error typically occurs in scenarios where:
  
  You are trying to aggregate data (e.g., using SUM, AVG, COUNT) and have included the same field or variable multiple times in the aggregation function.
  The aggregation function is designed to operate on unique instances of data, and using the same field multiple times can lead to ambiguity in the calculation.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Calculation Logic: Check the calculation or aggregation logic where the error is occurring. Look for instances where the same field or variable is being used more than once in the same aggregation function.
  
  
  Modify the Aggregation: If you find that the same field is being used multiple times, you will need to modify your aggregation logic. This could involve:
  
  Removing the duplicate usage of the field.
  Changing the aggregation function to ensure that each field is only used once.
  If necessary, consider using different aggregation functions or restructuring your calculation to avoid the duplication.
  
  
  
  Test the Changes: After making the necessary adjustments, test the calculation to ensure that it now executes without errors and produces the expected results.
  
  
  Related Information:
  
  Aggregation Functions: Familiarize yourself with the specific aggregation functions you are using and their requirements. Common aggregation functions include SUM, AVG, MIN, MAX, and COUNT.
  SAP Documentation: Refer to SAP's official documentation or help resources for more detailed information on aggregation functions and best practices.
  Debugging Tools: Utilize SAP's debugging tools to trace the execution of your calculations and identify where the error is occurring.
  
  If you continue to experience issues after following these steps, consider reaching out to your SAP support team or consulting with a colleague who has experience with SAP calculations and aggregation functions.
