Can other project partners help with filling out the application form in Jems as well? If yes, what is the procedure for this authorisation? Does the Lead partner have to create an account and the AF for the project in Jems first and then give authorisation to the other partners?

First, the Lead Partner has to create his own account to access to Jems and to be able to initiate the creation of the application form.
The LP can then go to the “Project Privileges” section of the application form and give different types of rights to users of the Interreg Euro-MED Jems. Please note that partners must have a Jems account before they can be added to an application.

More information can be found in the Jems user documentation (https://jems.interact-eu.net/manual/), section “Project privileges”.
