• What is the cause and solution for SAP error message FDT_CHANGE_INFO790 - Input parameters were changed ?

  The SAP error message "FDT_CHANGE_INFO790 Input parameters were changed" typically occurs in the context of SAP's Form Data Management (FDT) framework, which is used for managing forms and their associated data. This error indicates that the input parameters for a function or process have been modified in a way that is not expected or allowed.
  Cause:
  
  
  Parameter Modification: The error usually arises when the input parameters for a function module or method are altered after they have been defined. This can happen due to:
  
  Changes in the data structure or format of the input parameters.
  Incorrect mapping of input parameters in the form or data processing logic.
  Changes in the underlying data model that affect how parameters are passed.
  
  
  
  Version Mismatch: If there are multiple versions of a form or function module, and the version being called does not match the expected input parameters, this error can occur.
  
  
  Custom Code Issues: If there is custom code that manipulates input parameters before they are passed to a function, it may inadvertently change them in a way that leads to this error.
  
  
  Solution:
  
  
  Review Input Parameters: Check the definition of the input parameters in the relevant function module or method. Ensure that they match the expected structure and data types.
  
  
  Debugging: Use the SAP debugger to trace the execution of the program or function where the error occurs. This can help identify where the parameters are being changed.
  
  
  Check for Custom Code: If there is custom code involved, review it to ensure that it is not inadvertently modifying the input parameters. Look for any assignments or transformations that could lead to changes.
  
  
  Form Configuration: If the error is related to a specific form, review the configuration of that form in the FDT. Ensure that all mappings and data bindings are correctly set up.
  
  
  Version Control: If there are multiple versions of the form or function, ensure that the correct version is being used and that all dependencies are aligned.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific function or form you are working with. There may be known issues or updates that address this error.
