• What is the cause and solution for SAP error message FDT_HANA106 - &1: HANA database type &2 cannot not be mapped to an ABAP type ?

  The SAP error message FDT_HANA106 indicates that there is a mismatch between the HANA database type and the ABAP data type. This typically occurs when you are trying to map a HANA data type to an ABAP type that is not compatible or does not exist in the ABAP type system.
  Cause:
  
  Incompatible Data Types: The HANA database may have a data type that does not have a corresponding ABAP type. For example, certain HANA types like STRING, BLOB, or CLOB may not have direct equivalents in ABAP.
  Custom Data Types: If you are using custom data types in HANA that are not recognized by ABAP, this can lead to mapping issues.
  Data Type Changes: If there have been changes in the HANA database schema (like changing a column type) that are not reflected in the ABAP Dictionary, this can cause mapping errors.
  
  Solution:
  
  Check Data Type Compatibility: Review the HANA data types being used and ensure that they have corresponding ABAP types. You may need to adjust the HANA data types or create a compatible ABAP type.
  Modify the ABAP Dictionary: If you are using a CDS view or a table that is causing the issue, you may need to adjust the ABAP Dictionary definitions to ensure that the types match.
  Use Compatible Types: If you are using types like STRING, consider using CHAR or VARCHAR in HANA, which have direct mappings in ABAP.
  Update Data Model: If the HANA model has changed, ensure that the ABAP program or data model is updated accordingly to reflect these changes.
  Consult Documentation: Refer to SAP documentation for the specific versions of HANA and ABAP you are using to understand the supported data types and their mappings.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on data type mappings.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  HANA Studio: Use HANA Studio or SAP HANA Database Explorer to inspect the data types in your HANA database and ensure they are correctly defined.
  ABAP Development Tools: Utilize ABAP Development Tools (ADT) in Eclipse to analyze and modify your ABAP code and data definitions.
  
  By addressing the data type compatibility and ensuring that both HANA and ABAP are aligned in terms of data types, you should be able to resolve the FDT_HANA106 error.
