Replication with CREMAS idoc extension

Hi experts,

We're implementing a MDG-S hub and one of our project requirements is to replicate some custom fields of the Supplier, so we implemented a custom entity on MDG BP model and a CREMAS05 idoc extension, say ZCREMAS.

Now we need to replicate the suppplier custom data using the ZCREMAS idoc but we don't know if we're following the correct approach on MDG IMG.

Should we create a copy of CL_MDG_BS_VEND_ALE_DRF class and assign it into the customizing node MasterData Governance -> Data Replication -> Enhance Default Settings for Outbound Implementations?

And should we create a copy of  MASTERIDOC_CREATE_CREMAS function module to fill the custom data and call it on SEND_CREMAS_IDOC method of the copied class?

Thanks in advance.

Best regards,

Jordi
