Tp populate customer information in Scout, you first have to first be in a job in SWRemote. It doesn't matter what step you're on within SWRemote, just tap the Scout Responses button in the SWRemote menu:
Once you tap on Responses, you are now in the Scout sub section of SWRemote. From here, you can now view already filled out responses or this customer.
To start a new form, tap the big blue button in the lower right hand corner.
Scout will launch, if it is not already open. It will fill in the customer as well as the assigned User to yourself.
From here, select the form you wish to fill out from the form dropdown menu. You must also tap on the Assign to Admin Upon Completion dropdown. Finally, add in a simple Response Description.
Once the above steps have been completed, go ahead and tap the Save button in the upper right hand corner.
