• What is the cause and solution for SAP error message FDT_CORE100 - Data object conversion not possible (&1 &2 to &3 &4 / general mismatch) ?

  The SAP error message FDT_CORE100 indicates that there is a problem with data object conversion, specifically a mismatch between the expected data types or formats. This error typically arises in the context of SAP's Flexible Data Types (FDT) framework, which is used for handling various data formats and structures.
  Cause:
  The error message FDT_CORE100 can occur due to several reasons, including:
  
  Data Type Mismatch: The source and target data types are incompatible. For example, trying to convert a string to a numeric type without proper formatting.
  Incompatible Structures: The structure of the data being processed does not match the expected structure. This can happen if the data is coming from different sources or if there are changes in the data model.
  Null or Empty Values: Attempting to convert null or empty values can lead to this error if the target data type does not allow such values.
  Incorrect Mapping: If there is a mapping defined between source and target fields, and the mapping is incorrect or incomplete, this error can occur.
  
  Solution:
  To resolve the FDT_CORE100 error, you can take the following steps:
  
  Check Data Types: Verify that the data types of the source and target fields are compatible. Ensure that any necessary conversions are handled correctly.
  Review Data Structures: Ensure that the data structures being used match the expected formats. If there have been changes to the data model, update the mappings accordingly.
  Handle Null Values: Implement checks to handle null or empty values before attempting conversions. You may need to provide default values or handle exceptions.
  Validate Mappings: Review the mappings between source and target fields to ensure they are correct. Make sure that all required fields are mapped appropriately.
  Debugging: Use debugging tools to trace the data flow and identify where the conversion is failing. This can help pinpoint the exact cause of the mismatch.
