• What is the cause and solution for SAP error message FDT_CORE812 - No check for variable &1 possible; data-dependent conversion into text ?

  The SAP error message FDT_CORE812 indicates that there is an issue with the conversion of a variable into text format within the context of the Flexible Data Import (FDI) framework. This error typically arises when the system is unable to perform a check on the variable due to its data-dependent nature, which means that the conversion process cannot be completed as expected.
  Cause:
  
  Data Type Mismatch: The variable in question may have a data type that is not compatible with the expected text format. For example, if the variable is a complex data type or a structure that cannot be directly converted to a string.
  Missing Conversion Logic: There may be no defined conversion logic for the specific data type of the variable, leading to the inability to convert it into a text representation.
  Dynamic Data: The variable may contain dynamic or runtime data that cannot be evaluated at the time of conversion, causing the system to fail in performing the necessary checks.
  
  Solution:
  
  Check Data Types: Review the data types of the variables being used in the FDI process. Ensure that they are compatible with the expected text format. If necessary, modify the data type or the way the data is being handled.
  Define Conversion Logic: If the variable is of a custom or complex type, consider implementing a custom conversion logic that explicitly defines how to convert that variable into text.
  Debugging: Use debugging tools to trace the execution of the FDI process and identify where the conversion is failing. This can provide insights into the specific variable causing the issue.
  Review FDI Configuration: Check the configuration settings of the FDI framework to ensure that all necessary mappings and conversions are correctly defined.
  Consult Documentation: Refer to SAP documentation or community forums for any known issues or additional guidance related to the FDI framework and the specific error message.
