Abbreviated Name Field

The Company Information Table

In the Abbreviated Name field, you can enter an abbreviation (four characters max) for the name of your company.

If the Show Abbreviated Name field is selected, the abbreviated name is displayed in the title bar of all windows opened in the RoleTailored client for this company. If you are working with more than one company at the same time, the abbreviated name in the title bar helps you keep track of which company you are working in.
