Connection
Here is a list of all available connections. Choose the one you want to use for this function. The connections can be maintained in the "Settings and configuration" area. If you have access to more than one user, you can specify a connection to the same system / client for each of them - it increases your chances to have success with the functions. System users often have a wider set of authorizations than dialog users. Thus, if you have knowledge about the credentials of a system user, it is definitely worth a try to use it.
