If you are using the multi-entity feature of VersAccounts, you can assign facilities by entity so that for each of your entity, only its related facilities are shown when you are in the application.
First you need to activate the setting Link Facilities to Entity under Admin View, Enterprise Setup, Firm Settings. Save the setting and then head to Facilities list under User View, Products, Setup, Facilities. Edit each facilities and choose the entities linked to the facility, you can choose one or more entities.
After the facilities are linked to entities, when you log in and switch from entity to entity, only the associated facilities will show for the currently selected entity.
