2.1.6 Entry and Modification of Configuration Data

Only one user is allowed to edit a project at a time. To enter "Edit" mode, click the Edit button above the tabs. This locks the project, preventing other users from editing the data until you have either saved your changes by clicking Save or discarded your changes and reverted back to the original data by clicking Cancel.
NOTE:  Once Edit is clicked, it turns grey (an indication that the project is ‘locked’) and remains so until Save or Cancel is clicked. In order to make any additional changes after clicking Save or Cancel, the user must enter "Edit" mode again.
On some tabs, it is possible to add new rows or columns by either clicking the Add Row or Add Column drop-down button located beneath the grid (at the bottom left of the window), or by right clicking on the grid and selecting the New Row or New Column option.
