On the companies tab you are able to view the ID's and the names of all the companies on your system. You will also be able to search companies using the quick search bar at the top of the screen.
As all companies are created/linked from Chameleon-i, you have nothing to edit in Timesheets. All editing for Companies would be done at Company record level in Chameleon-i.
1. You can search for specific company records to check if they are on the system by using the criteria here.
2. You can sort the columns alphabetically ascending or descending to help you get to the record you want.
