- All application scopes
- This scope only
47
When creating a table, what is the default name of the application? Of the module?
- The name of the table
- The plural of the table name
48
What does the default module of a table direct to?
A list of records within the table.
49
When configuring a module, what does the "Link type" dictate?
The type of page the module holds.
- ie List of records, New record, URL etc.
50
When creating a new UI policy, what do you need to first do before you can add actions?
Save the new record
51
Why does a UI policy have better performance than a client script?
The UI policy has a condition. It only runs when that action is true. Client scripts, however, do not have trigger conditions and will always evaluate.
52

55
What must you do before you can access the advanced script of a UI policy?
- Save the record, if it is new
- Click the "Advanced view" related link (NOT the context menu)
56
What does the "Global" checkbox on a UI policy do?
When true, it applies to all views for that table.
57
What is the default value for the UI Policy "On load" field?
The course says "The onLoad checkbox deals with whether this UI policy should execute when the form is loaded. The default behavior for a UI policy is to execute when the user makes a manual change to a field on a form. If we do want this to be evaluated also when the form is loaded, we would need to check the onLoad checkbox"
This isn't true at least from what I can tell in our instance. When I went to create a new UI policy, the onLoad field was checked. When I looked at its dictionary entry, its default value is true.
58
Would you need a UI policy or client script to keep track of a fields prior value?
Client script.
59
Which executes first: UI policies or client scripts?
Client scripts
60
What is the syntax for setting a display business rule scratchpad variable?

76
What happens if you have a script in one application scope that deletes records but the caller application does not have delete access?
What if the script also contains an insert and the caller application DOES have access?
- It would not throw errors nor update system logs because unauthorized access is simply skipped/ignored.
- The insert would proceed still.
77
Within the "Application Access" tab of table configuration, what does the "Allow configuration" checkbox control?
