Transport Connection (Rules) 

All changes you make to a calculation rule must be transported from your Customizing client to the other clients in your SAP System. If your Customizing client has been set up accordingly, the system can automatically include all changes in a transport request. If this is not the case, you must include each rule that you have changed in a transport request to ensure they are transported.

For more information about setting up the transport system and about transport requests, see the SAP Library under Transport Organizer.
