Company selection window
If you've set up RDA, a 'Remote Data Access' column appears in the Company Selection window when you open the software.
This shows either 'Online' or 'Offline' next to your company. If it's blank, you've not set up RDA.
TIP:
In Sage 50 Accounts v27, this is also where you can check if you're at a main or remote site.
