In SAP HANA, Delivery unit is known as single unit, which can be mapped to multiple packages and can be exported as a single entity so that all the packages assigned to Delivery Unit can be treated as a single unit.
Delivery units can be used to export all the packages that make a delivery unit and the relevant objects contained in it to a HANA Server or to the local Client location.
The user should create Delivery Unit prior to using it. This can be done through HANA Modeler -> Delivery Unit -> Select System and Next -> Create -> Fill the details like Name, Version, etc. -> OK -> Add Packages to Delivery unit -> Finish
