• What is the cause and solution for SAP error message FDT_CP_MSG184 - Unsupported type used in structure &1 component &2 ?

  The SAP error message FDT_CP_MSG184 indicates that there is an unsupported data type being used in a structure component within the context of the Field Data Tool (FDT). This error typically arises when the data type defined in the structure is not compatible with the expected types in the FDT framework.
  Cause:
  
  Unsupported Data Type: The structure component is defined with a data type that is not recognized or supported by the FDT. This can happen if the data type is custom or if it is a type that the FDT does not handle.
  Incorrect Mapping: There may be an issue with how the data types are mapped in the FDT configuration, leading to the use of an unsupported type.
  Version Compatibility: The version of the FDT or the underlying SAP system may not support certain data types, especially if there have been recent updates or changes.
  
  Solution:
  
  Check Data Types: Review the data types used in the structure component. Ensure that they are standard types supported by the FDT. Common supported types include CHAR, NUMC, DATS, TIMS, etc.
  Modify Structure: If you find that an unsupported type is being used, consider modifying the structure to use a supported data type. This may involve changing the data type in the ABAP Dictionary (SE11).
  Update FDT Configuration: If the mapping in the FDT is incorrect, update the configuration to ensure that the correct data types are being used.
  Consult Documentation: Refer to the SAP documentation for the FDT to understand the supported data types and any limitations that may apply.
  Check for Updates: Ensure that your SAP system and FDT are up to date. Sometimes, newer versions may support additional data types.
