• What is the cause and solution for SAP error message FDT_EXPRESSIONS524 - Function &1 has more than one exporting parameter ?

  The SAP error message FDT_EXPRESSIONS524 indicates that a function module or method you are trying to use has more than one exporting parameter, which is not allowed in certain contexts, particularly when using expressions in the context of the SAP Fiori or SAP UI5 applications.
  Cause:
  The error occurs because:
  
  The function or method you are trying to call is defined with multiple exporting parameters.
  The context in which you are trying to use this function does not support multiple exporting parameters, such as when using expressions in a data binding scenario.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Modify the Function Module/Method:
  
  If you have control over the function module or method, consider modifying it to return a single exporting parameter or to use a structure or table to encapsulate multiple values.
  
  
  
  Use a Wrapper Function:
  
  Create a new function module or method that calls the original function and consolidates the multiple exporting parameters into a single structure or table. This wrapper can then be called in the context that requires a single exporting parameter.
  
  
  
  Check the Context:
  
  Ensure that you are using the function in a context that supports multiple exporting parameters. If you are using it in a UI5 application, check the data binding and ensure it is compatible.
  
  
  
  Review Documentation:
  
  Check the SAP documentation for the specific function module or method to understand its parameters and usage. This can provide insights into how to properly call it.
  
  
  
  Debugging:
  
  If you are unsure where the error is originating, use debugging tools in SAP to trace the execution and identify the exact point of failure.
  
  
  
  Related Information:
