Each process line that is added to a job order, has an approval status field.

By default, when a process line is first inserted the approval status is set to Red, denoting the process line is not approved
The intention of this approval field is to denote to other users within the business whether the process can be undertaken.
It has three colour statuses:-
Red: Process line should not proceed.
Green: Process Line can proceed.
Amber :The process line can be applied to a single item, which is then photographed and sent to the client for approval; upon approval, the status will be updated to green and the process line can be applied to the whole quantity.
Note: The above meanings are an example usage. There is no functionality attached to the process line approval status, so you may wish to apply your won workflow conditions / interpretation to is as you require.
Given this meaning, you should only manually toggle the status to green when you are content that the process line can be undertaken by the corresponding department.
Some example should help clarify usage.
Example One:
Consider that you have received a client order for 10,000 T shirt prints,
on condition that a sample print is first produced, and sent to the client
for approval.
Upon approval the 10,000 print run can occur.
This can be represented as two job orders and written up consecutively:-
For the stroke one, the print process line would be set to Green, denoting that the print can occur
For the stroke two, the print process line would be set to Red, denoting that the print cannot occur.
Upon the successful approval of the sample, the print process line on the stroke two job would be updated to green, denoting that the process is now approved to commence.
Example Two:
Consider that you receive a client order for a 500 T Shirt print run,
but the customer want to see a photograph of the first shirt printed before
printing the remainder.
The job order would be written up and the print process line manually set
to a status of Amber, and a note added to state take photograph and send
to client.
When the print tooling is set up ready to execute the print run, print
staff will interpret the Amber approval status in conjunction with the
note and only print one shirt, and take a photo for customer approval.
Once approved,.the print process line would be updated to green and the
print run fully executed.
