NUMC or DATS gets converted to Varchar in Oracle

Hello All,

We are replicating data from SAP to Oracle. 

For any field of SAP type NUMC or DATS, once it gets replicated to Oracle, those fields are defined as Varchar in Oracle.

I did try to define settings in table IUUC_REPL_TYPMAP, but it makes no difference.  I have the impression that this table is only useful for replications to Hana, not to an Oracle DB.

Has anyone witnessed a similar beheviour?

Thanks,

Pawel Mierski
