SAP provides a set of user defined datatypes and datatype classes. You can use them to change the datatype of column values when you replicate between:
SAP data servers
SAP data servers and non-SAP data servers
Homogeneous non-SAP data servers
Heterogeneous non-SAP data servers
A datatype definition describes a non-SAP datatype in terms of a base SAP Replication Server native datatype. The base datatype determines the maximum and minimum length associated with the datatype definition and provides defaults for other datatype attributes. The base datatype also defines the delimiters associated with the datatype definition.
SAP ASE – rs_sqlserver_dt_class
SAP SQL Anywhere – rs_asa_dt_class
DB2 – rs_db2_dt_class
Microsoft SQL Server – rs_msss_dt_class
Oracle – rs_oracle_dt_class
SAP HANA database – rs_hanadb_dt_class
For a list and description of supported datatype definitions for each datatype class, see the Heterogeneous Replication Guide.
