If you are wanting someone to have access for the first time to any database that you may use at your centre, then this is a very easy process and may not require you to contact ISG for action.
It pays to note that some of TSA Lotus Notes applications/databases are open to any staff member, and some are set up with security access that requires prior approval by the relevant line managers, so you will need to ensure that the person has access to this and if not, a request is sent through to ISG.
However, giving them the link to the application is a simple process and you can do this yourself by emailing them a link for their workspace.
Go to your workspace and select the required application. Then right click on it, and highlight 'Application' , then 'Copy as Link'.
You can now paste the copied link into an email and send it to the appropriate person. The link will look like a small book icon.
They simply need to click on the icon and the link will be automatically added to their workspace. If they have not been granted access, then when they click on the link Notes will give them an error message stating they are not authorised access. If this happens, then get the centre manager to send through a request for access to ISG.
