How can a customer create a Z version of an SAP DataSource

Hi,

I have a new DataSource created with RSA2 that will be delivered via SupportPackage to the customer. The corresponding new extractor function module and extract structure is already delivered via SAP note.

How can a customer who does not want to wait for the SupportPackage create the DataSource in the Z namespace based on the extractor function module of the SAP note?

The customer is not allowed to use RSA2; and RSO2 seems to be for a different purpose (generic DataSources).

Thanks, Frank
