Right-clicking on a menu option in Sage 100 allows you to open that option in a secondary company without changing-company for everything else, including screens that you already have open. This can be useful for several situations: 1) If you have multiple companies setup in your system, this is a quick way to respond to momentary requests for information from another company without leaving your current company. You can enter data like a customer-contact change, or transactions such as a manual-check or GL Entry in another company, while all other options stay-open in your current company. 2) you might check for history in a history company if your history files have gotten so large that you save history in a history-company, or check info on a former employee in a payroll prior-year backup company. 3) you might like to test a procedure or option in a TEST company (copy of your live company data) before trying it in your live company. Finally, you may want to look at one of the Sage demo-companies ABC, ABX, XYZ to see how they have setup or used a feature that you are considering. Using the right-click on a menu-option allows you to stay in your main company while momentarily doing things in any second company. This feature was added to Mas 90/200 for versions 4.20 forward, and it works with all modules including work-order and payroll.
