What are the different ways to send ZBAPIs to a different location?

Hello friends

There are some ZBAPIs that we have written which has to be given to a partnering company.

Instead of recreating the whole BAPIs and related structures and data elements etc.,, is there a way I can package them and send them.

For example, on XI side I can export the mappings etc., to a tpz file which can be imported on a different server out side our network.

Any suggestions or feedback will be greatly apprecited.

Thanks

Ram
