create table in oracle from SAP, using the equivalent data types

i'm having my doubt about this......

i'm doing a copy of a table of a ABAP(MARA) on to a external ORACLE database, but this ABAP table has some data type that i don't know what's the equivalent on Oracle.

i haven't fine anything thats says about this 3 data type (QUANTITY, UNIT and NUMC) of ABAP and his equivalent ORACLE data type.

what i thing is that this are the ones...............

ABAP -

Quantity -

> Float

Unit -

> Char(3)

Numc -

> Char(255)

......... but don't want to wait to find out until a make the tests, does anybody knows about this?

thanks in advance.
