se61 transaction - create custom document

Hi @all,

we plan to create our custom notifications by copying the standard ones from SAP in the se61 transaction - for example, for the FireFighter controller (he is notified when a FireFighter session is initiated).

We are stuck at the following point: we cannot save any custom created document because we don't know what the package attribute is. We have tried to do it like illustrated in the screenshot below, but we got an error saying that the package is incorrect. What package do we have to choose? And what are these packages, where can they be maintained?

We do not want to save these documents as local objects (marked on the screenshot), because we want to transport them later to the productive system.

Thanks in advance.

Kind regards,

EM
