• What is the cause and solution for SAP error message FDT_CORE134 - Type of value for &1 may not be a structure ?

  The SAP error message FDT_CORE134 indicates that there is an issue with the data type being used in a certain context, specifically that the type of value for a given field (denoted as &1) is not a structure. This error typically arises in the context of Field Data Tool (FDT) or when working with data structures in SAP.
  Cause:
  
  Incorrect Data Type: The error usually occurs when a field is expected to be a structure (a composite data type that can contain multiple fields) but is instead being treated as a simple data type (like a string, integer, etc.).
  Configuration Issues: There may be a misconfiguration in the data model or mapping where a field is incorrectly defined.
  Data Mapping Errors: If you are mapping data from one structure to another, the source or target field may not match the expected structure type.
  
  Solution:
  
  Check Field Definitions: Review the field definitions in the data model or mapping configuration. Ensure that the field in question is defined as a structure if it is supposed to be one.
  Adjust Data Types: If the field is incorrectly defined as a simple type, change it to a structure type in the configuration.
  Review Mappings: If you are working with data mappings, ensure that the source and target fields are compatible. Adjust the mappings to ensure that structures are being used where required.
  Debugging: If you have access to debugging tools, you can trace the execution to see where the type mismatch occurs and correct it accordingly.
