I created a grid on the sales order page with drop downs threw out the grid.
When I create a new sales order and enter things into the grid and hit save. It not only saves the current grid on the screen, it also saves other sales orders the same way.
For example: We sell storage sheds. We normally collect a list of names/employees who have worked on the building during production. Every sales order has a list of different names depending on time of day it was built. When I enter the names and hit save. All my saleso orders change to the info I just entered. So if I enter names into sales order #15 and and go to #16 and enter the names, #15 changes to what I entered for #16.
