• What is the cause and solution for SAP error message FDT_EXPRESSIONS661 - Context DO &1 of function &2 in step &3 won't be filled by mapped value ?

  The SAP error message FDT_EXPRESSIONS661 typically occurs in the context of SAP's Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework. This error indicates that a specific context (in this case, "DO &1") of a function (denoted as "&2") in a particular step (denoted as "&3") is not being populated with the expected mapped value.
  Cause:
  
  
  Mapping Issues: The most common cause of this error is that the mapping between the source data and the target context is not correctly defined. This could be due to:
  
  Missing or incorrect mapping definitions.
  The source field does not contain a value that can be mapped to the target context.
  Data type mismatches between the source and target fields.
  
  
  
  Data Quality Issues: The source data may not contain valid or expected values, leading to the failure in populating the target context.
  
  
  Configuration Errors: There may be issues in the configuration of the FDT or FDI process, such as incorrect function module settings or missing parameters.
  
  
  Execution Context: The context in which the function is being executed may not be set up correctly, leading to the inability to fill the context with the mapped value.
  
  
  Solution:
  
  
  Check Mapping Definitions: Review the mapping definitions in the FDT/FDI configuration. Ensure that all necessary mappings are correctly defined and that the source fields are correctly linked to the target contexts.
  
  
  Validate Source Data: Inspect the source data to ensure that it contains valid values that can be mapped to the target context. Look for any null or unexpected values that may cause the mapping to fail.
  
  
  Review Configuration: Go through the configuration settings of the FDT/FDI process. Ensure that all required parameters and settings are correctly configured.
  
  
  Debugging: If the issue persists, consider using debugging tools to trace the execution of the function and identify where the mapping is failing. This can provide insights into the specific conditions leading to the error.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to FDT/FDI for any known issues or additional troubleshooting steps.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who has experience with FDT/FDI processes.
