Hello Vivek,
the usage of ABAP Data Types (like data elements, structured, table types) is not possible in HANA native artifacts like stored procedures or structured types. In that artifacts primitive types and structured types can be used like described in the documentation (e.g. CREATE TYPE - SAP HANA SQL and System Views Reference - SAP Library or CDS Structured Type Definition - SAP HANA Developer Guide for SAP HANA Studio - SAP Library).
In relation to stored procedures you can use ABAP types in the interface definition of ABAP Managed Database procedures. This is possible because these objects are ABAP managed. When the stored procedures are created on the HANA database (when executed the first time) the ABAP types are converted to the according HANA types.
Best Regards,
Florian
