The easiest way to deploy/undeploy a component in SAP PI/PO for developers

If you want to deploy (or undeploy) a component, e.g. (a new version of) an adapter in SAP PI / PO, then you have multiple possibilities to do so. You can use the Software Update Manager (SUM), you can use JSPM or even write a user defined script, e.g. in Gradle, that uses ant. But the deployment with SUM and JSPM you need access to this tools and this is normally a task for SAP basis people. And writing a gradle script is not a trivial task.

So IMHO the best way for a developer to deploy a component is to use the Eclipse-based NetWeaver Development Studio (NWDS). In NWDS you can open the Deployment view by going to Window -> Open Perspective -> Other ... and then select Deployment. If the Repository Explorer on the left-hand side is empty than you are not connected to a PI system. To connect to your PI / PO system go to Windows -> Preferences and type "SAP AS Java" in the filter text field. Select SAP AS Java and click the Add button. Then you have to specify the host name of your system. The instance number should normally be 0 and the domain default. Click OK. After that you should see the PI / PO system in repository explorer in Deployment view.

When you expand the node, you'll see all components deployed on the system. You can right-click on a component and select "Add to Undeployment List" or drag-and-drop it to the undeployment list and click "Start". To deploy a new component you have to import the sca-file from your workspace or the file system. If everything was fine, you should receive a success message.

One more thing to think about is the deployment / undeployment strategy. You can configure it in settings section under deployment / undeployment list. For undeployment you can decide, whether to stop the process or to undeploy depending components if there are some. For deployment you have to choose whether only components with lower versions have to be updated or components with lower and equal versions or components with any version (which means that components with higher version can be replaced with ones with lower version which can be usefull to test a behavior in a previous version of the component).

That's it! It is a quick and easy way to make the deployment of a component on SAP PI / PO.
