• What is the cause and solution for SAP error message FDT_HANA105 - HANA database type &1 cannot not be mapped to an ABAP type ?

  The SAP error message FDT_HANA105 indicates that there is an issue with mapping a HANA database type to an ABAP type. This typically occurs when there is a mismatch between the data types defined in the HANA database and the corresponding types that ABAP can recognize and handle.
  Cause:
  
  Data Type Mismatch: The HANA database type being used is not compatible with any of the ABAP data types. This can happen if the HANA type is a custom type or a type that does not have a direct equivalent in ABAP.
  Unsupported Data Types: Certain HANA data types, such as complex types (e.g., JSON, XML) or specific numeric types, may not have a corresponding ABAP type.
  Changes in Database Schema: If the database schema has been modified (e.g., new columns added with unsupported types), it can lead to this error when trying to access or manipulate the data in ABAP.
  
  Solution:
  
  Check Data Types: Review the HANA database schema to identify the data type of the column that is causing the issue. Compare it with the available ABAP data types to find a suitable mapping.
  Modify Data Types: If possible, change the data type in the HANA database to one that can be mapped to an ABAP type. For example, if a column is defined as a complex type, consider changing it to a simpler type like VARCHAR or INTEGER.
  Use Views: Create a HANA view that transforms the complex or unsupported types into simpler types that can be easily mapped to ABAP.
  Update ABAP Code: If the ABAP code is expecting a certain type, ensure that it is updated to handle the correct type as per the HANA database schema.
  Consult Documentation: Refer to SAP documentation for the specific version you are using to understand the supported data types and their mappings.
