The three are the contract or order, your drawings and the programme, in any order.
Drawings take several files at once. Each one files itself into its revision series from a file name such as A-101-Rev-D.pdf.
The contract or order is one row, because a job comes with one of them: a subcontract, a work order, a purchase order or a letter of intent, whatever your builder sends.
YourCA reads which it is from the file name, and shows it as soon as it lands. If the name misled it, change it with the drop-down. You can also change it later on the Work order section of Prestart.
YourCA stores each one against the job as soon as it lands, and the screens that read it start to read it.
A drop of the contract or order here stores it. The in depth review on the Contract tab reads its clauses and gives you the dates. Until a review has read it, Read it now on the row opens that review with the file already in it.
If you skip any of them, the job still runs. The screens that need a contract say which term is missing. They show no figure.
When a new revision of any of them arrives, drop it on the tab that holds it. YourCA keeps the old one and tells you what moved.
Not on this job puts one row aside, for this job only.
Hide for a week puts the list away for seven days. It comes back after that while rows are left.
None of them takes a drop away. The contract still goes on the Contract tab, the drawings on Documents and the programme on Schedule.
When every row is on file or set aside, the list goes for good on this job. It does not come back if a row later reads as missing. After that, put a new file on the tab that holds it. YourCA remembers this on the device you finished it on.
Only the people who set a job up see this list. By default, those are the Owner, Office and Project manager roles, because they can set the job's programme. A foreman, a field worker, Accounts and Read only never see it. If you give a role Set the programme under Who can do what, it also gets the list.
