You can assign equipment to a location. When setting up equipment, you can show who installed the equipment at this location. This list can be of your technicians, but in order for any competitors to show up, you have to have them as a List Type. File > Administration > Application Configuration > Advanced > Advanced Configuration > List Types > New >
Type in your new list type in the name, keep the max length of 20, check either button, do not check Include Description.
Then go back into the Loc Equip > Tools > Customize > Control Prop > cboInstalledBy – change the cbListType to the new list type you set up earlier.
Click Save and you’re done!
