to pick a new location.
This will override the system-wide file locations.
Locking
Select a sales person or branch location to lock the customer list. When users login and use the customer window they will only be able to see customers for the chosen salesman/branch.
Note you can only pick one locked filter, not both.
Sage Passwords
Only applicable to the accounts link (additional module). When using the accounts link you need to enter your accounts package user name and password.
These settings allow you to pick default options for when a user starts new contact history. This would save the user always having to pick the same option if they do lots of repeat bookings.
Pick the defaults from the drop down list for:
Default Resource: Pick a resource name and tick the box to set as the default.
Default Action: Pick an action from the drop down list
Default Duration: Pick a default duration from the drop down list

<--Filters Only--> The user can only access the saved filters that you have set in projects (and no more)
[Name of filter] All of your saved filters are listed here and the user can only access that 1 filter in the window.
Appointments Diary Select a saved filter which already exists on the appointments diary. This user will only be able to access the filtered data on the diary.
