Replicating table from SQL server to NON-sql subscriber is failing

Hi All,

I am replicating a table from SQL server publisher to NON-sql Server Subscriber(Oracle) and it failing with below error

ORA-12899: value too large for column "APPDBA"."MPI_GENEALOGY"."SERIALNO" (actual: 42, maximum: 40) (Source: MSSQL_REPL_ORACLE, Error number: 12899)

I checked the source i.e SQL server and the datatype of SERIALNO is NVARCHAR(40) and in the destination its NVARCHAR2(40).

Please help me out so that i can replicate all the data successfully.
