You won’t see this option in all CCRSoftware applications.
QuickBooks maintains a number of “lists”. These include major lists such as the item list, customer list and vendor list, as well as smaller lists such as the sales rep list, terms list, and so forth.
To improve performance, CCRSoftware applications often make a copy of various lists into memory when the application starts or begins a particular process. These copies are made every time that you start the program (or possibly the first time the program needs the information). If you have the CCRSoftware application open, and then you make a change or addition to a list in QuickBooks itself, the CCRSoftware application might not be aware of the change right away.
If you make changes in the QuickBooks lists while this is open, you can click the Refresh menu to “refresh” or re-load the list into the application from the QuickBooks company file. In some cases you will have the option of selecting the list to refresh.
You only need to do this if you leave the CCRSoftware application open while you are making changes to lists in QuickBooks, and you want those changes to come through to the application right away.
