For example, you need to plan, manage, and maintain the application versions you want to ship, and you need to
ensure that a stable plan exists to provide support for existing and all future versions of your application.
SAP HANA lifecycle management uses the delivery unit (DU) is a vehicle to ship one or more software
components from SAP (or a partner) to a customer. Delivery Units correspond to an "application" with versions,
for which support packages and patches are delivered. You can also use the delivery unit to transport content
between SAP HANA systems, for example, between development systems or between development and
productive systems.
Note: Delivery units are not to be confused with development classes; delivery units are similar to
software component versions in the Product Availability Matrix (PAM).
The Application-Development Lifecycle
Application development on SAP HANA requires a server-centric life cycle for design-time objects, which are the
development artifacts that you store in the SAP HANA repository. As an application developer, you check out
design-time content from the repository and edit a copy of the checked-out artifact in the local file system on the
your personal computer (PC). The following steps provide a brief, high-level overview of the development lifecycle
for design-time content:
1. Check out design-time content.
Check out the package containing the design-time artifacts you want to work on (if the package already
exists).
2. Edit the design-time content.
Edit the copies of the design-time artifacts, which are stored in your SAP HANA repository "workspace" on
your local file system; the local copies of the design-time artifacts are created during the checkout process.
3. Commit changes to design-time content.
Committing the changes you have made to the design-time artifacts creates new versions of the artifacts in
the SAP HANA repository. Note that identical (unchanged) versions of a file are not committed.
4. Activate changes to design-time content.
Activating the changes you have made to the design-time artifacts makes these changes available to
applications and other users, creating runtime objects where necessary.
13.3 Exporting Delivery Units
Exporting a delivery unit (with all packages and dependencies) is the mechanism SAP HANA uses to enable the
transfer of delivery units between systems, for example, to transport application content between development
systems of from a development system to a consolidation system.
The SAP HANA studio includes a mechanism that enables you to export and import delivery units. You can use the
export feature to create an image of a delivery unit, which you can store either on the SAP HANA server or in the
file system of a selected client for future import to another system. You can also export development objects as
an archive that you can send to SAP support or share with other members of the development team.
