• What is the cause and solution for SAP error message FDT_CORE055 - Invalid method call, no structured input supplied ?

  The SAP error message FDT_CORE055: Invalid method call, no structured input supplied typically occurs in the context of SAP's Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework. This error indicates that a method was called without the necessary structured input data, which is required for the method to execute properly.
  Cause:
  
  Missing Input Data: The most common cause of this error is that the method being called expects a structured input (like a table or a specific data format), but none was provided.
  Incorrect Configuration: The configuration of the FDT or the data transfer process may be incorrect, leading to the absence of required input data.
  Data Mapping Issues: If the data mapping between the source and target structures is not set up correctly, it may result in the absence of expected input data.
  Programmatic Errors: If the method is being called programmatically (e.g., through ABAP code), there may be a logic error that prevents the structured input from being passed correctly.
  
  Solution:
  
  Check Input Data: Ensure that the method being called has the necessary structured input data. Review the data being passed to the method and confirm that it meets the expected format.
  Review Configuration: Go through the configuration settings of the FDT or FDI process to ensure that all required fields and structures are correctly defined.
  Validate Data Mapping: Check the data mapping settings to ensure that all necessary fields are mapped correctly from the source to the target.
  Debugging: If the error occurs in a custom program, use debugging tools to trace the execution and identify where the structured input is missing.
  Consult Documentation: Refer to SAP documentation or help resources for the specific method being called to understand its requirements and expected input structure.
  Error Handling: Implement error handling in your code to manage cases where structured input might be missing, providing fallback mechanisms or user notifications.
