• What is the cause and solution for SAP error message /SAPAPO/PE237 - Two selection parameter (&1 and &2) cannot use the same data element &3 ?

  The SAP error message /SAPAPO/PE237 indicates that there is a conflict in the selection parameters used in a particular transaction or report within the SAP Advanced Planning and Optimization (APO) module. Specifically, the error states that two selection parameters (identified as &1 and &2) cannot use the same data element (identified as &3). This typically occurs when the same data element is being referenced for multiple selection criteria, which is not allowed in the context of the operation being performed.
  Cause:
  
  Duplicate Selection Parameters: The error is often caused by having two selection fields that are trying to use the same data element. For example, if you have two filters for the same characteristic (like a material number) in a report or selection screen, it can lead to this error.
  Configuration Issues: There may be a misconfiguration in the selection screen of the report or transaction that is causing the same data element to be referenced multiple times.
  Custom Development: If there are custom reports or enhancements, the issue might stem from the way the selection parameters were coded.
  
  Solution:
  
  Review Selection Parameters: Check the selection screen of the transaction or report where the error occurs. Ensure that you are not using the same data element for multiple selection parameters. If you find duplicates, modify the selection criteria to use different data elements.
  Modify Custom Code: If the error arises from custom development, review the code to ensure that the selection parameters are defined correctly and do not reference the same data element.
  Consult Documentation: Refer to the SAP documentation for the specific transaction or report to understand the expected configuration of selection parameters.
  SAP Notes: Check for any relevant SAP Notes that might address this issue. Sometimes, SAP releases notes that provide fixes or workarounds for known issues.
