Hi Cristian,
well you can do / try that, but it is not supported in a SAP environment.
SQL Apply means Logical Standby database and this is explicitly not supported in a SAP environment - for more details please check SAPnote #105047 (sub point 14 - Oracle Data Guard).
However from a technical point of view it is possible as none of these restrictions usually apply a SAP environment ( Data Type and DDL Support on a Logical Standby Database ).
Regards
Stefan
