Function strings are added to the Replication Server default rs_hanadb_function_class.
The function string class replaces several default
Replication Server function strings with custom function strings designed to communicate
with a HANA DB data server and access replication-related tables and procedures.
Warning! ExpressConnect for HANA DB
supports the replication of LOB columns that use default Replication Server function
strings for text and image processing. ExpressConnect for HANA DB does not support
custom function strings for text and image processing. If you override the default
Replication Server LOB processing with custom function strings for
rs_writetext, rs_textptr_init, or other
LOB-related function strings, text and image processing will fail.
