View characterizes the game plan of fields on a frame or a rundown. For one single shape, we can characterize different perspectives as indicated by the client inclinations or prerequisite.

8. What is ACL?

An ACL is Access Control List that defines what data a user can access and how they can access it in service now.

9. What do you mean by impersonating a user? How it is useful?

Impersonating a user means that you can log in to the system as that user and can have felt how the service-now UI is set for that user. This is very useful while testing. For example, if you are required to test that a user can access change form or not. You can impersonate that user and can test instead of logging out from your session and logging again with that user credentials.

12.What is dictionary override?

Dictionary Overrides provides the capability to override several properties of a field in the extended table.For example, change table is extended from task table.There is a field named status in task table and set as read-only.When we use this field in change form it will show be read-only.We can set this to non-read only by using the dictionary override. Similarly, there are other properties that can be set for the fields in an extended table.

13.About UI policy & What it is?

UI policies are alternative to client scripts.It can be used to set a field as mandatory, read-only and visible on a form. You can also use UI policy for dynamically changing a field on a form.

In any case, the default update set is marked as complete than the system creates alternate update named Default1 & uses it to update set.

36.Does Homepages and Content pages are added to the update sets?

39. What Do You Mean By Coalesce?

Coalesce is a property of a field that we use in transform map field mapping.When we set the coalesce as true for a field mapping it signifies that this field will work as unique key.If a field match is found with the coalesce field, then existing record will be updated with the imported information in target table else a new record will be inserted into the target table.

40. What Is Difference Between Ui Policy And Data Policy?

44. How To Set The Invalid Queries Into Empty Result Sets?

By default queries with invalid field names run but ignore the invalid condition. For more strict query control you can enable the glide.invalid_query.returns_no_rows property which will result in an empty result set for invalid queries.
