If process resources are to be used only within a particular process, they can be created directly below a parent process. This means that they can only be used in the process context and cannot be called from other processes.
Basically, the same resources can be created below an individual process as within a project – be it sub-processes, documents such as XML files, SQL statements or even adapters.
The resources to be used can be created both, via the context menu New > <Resource name> and via the toolbar 
The resources created can then be parameterizes as usually and integrated into the process diagram via drag & drop from the repository.
