• What is the cause and solution for SAP error message FPAPICHK035 - Already Sorted must be selected when using pass by reference ?

  The SAP error message FPAPICHK035 indicates that when using the "pass by reference" option in your ABAP program, the data being processed must be sorted. This error typically arises in the context of using certain function modules or methods that require sorted input data when they are called with reference parameters.
  Cause:
  The error occurs because the function module or method you are trying to call expects the input data to be sorted in a specific order. When you pass data by reference, the system checks if the data is already sorted. If it is not, the error message is triggered.
  Solution:
  To resolve this error, you need to ensure that the data you are passing to the function module or method is sorted before the call. Here are the steps you can take:
  
  
  Sort the Data: Use the SORT statement in your ABAP code to sort the internal table that you are passing by reference. For example:
  SORT it_table BY field1 field2.
  
  
  Check the Sorting Requirements: Review the documentation for the function module or method you are calling to understand the specific sorting requirements. Ensure that the fields you are sorting by match the expected order.
  
  
  Use the Correct Pass Method: If sorting is not feasible or if you do not want to sort the data, consider using "pass by value" instead of "pass by reference" if the function module or method allows it. This way, the data is copied rather than referenced, and the sorting requirement may not apply.
  
  
  Related Information:
  
  ABAP Documentation: Check the SAP documentation for the specific function module or method you are using to understand its parameters and requirements.
  Debugging: Use the ABAP debugger to inspect the internal table before the function call to ensure it is sorted as expected.
  Performance Considerations: Sorting large internal tables can have performance implications. If sorting is a frequent requirement, consider optimizing your data handling or reviewing your data structure.
  
  By following these steps, you should be able to resolve the FPAPICHK035 error and successfully pass your data to the function module or method.
