Hi @Shaik22 

Please check below answers

1. Difference between async and after BR,Where exactly we can use them.Please give me an example.

Async business rules are similar to after rules in that they run after the database commits a change. Unlike after rules, async rules run in the background simultaneously with other processes. Async business rules allow the system to return control to the user sooner but may take longer to update related objects

Another difference is that 'previous' cannot be referenced in async rules, and 'current' cannot be referenced on ‘delete'

'After' example(s):

On a child task, update field on parent record and redirect to parent=> The user will be redirected to the parent, so you want the business rule to be executing before returning control to the user

If a field changes from X to Y, do something=>async rules cannot do previous condition checks, so use after

Async example:

 When a parent is closed, close all children=>This operation could take a while, it is best to return control to the user immediately and work in the background.

2.Difference between Business rule and ACL.

Business rule used to perform operation when record insert/ update and delete and all used to restrict data for specific user. There is one Query business rule that work like eexact all but here else there are some differences like below

1.Query BR provide access restriction only in Row Level while ACL provide access restriction Global, table (Row) and field level.

2. When Query BR is restricting the access than user will not see any message by default at the bottom of page related to access restriction but while if it is restricted from ACL than message such as “Numbers of rows removed from the list by Security constraints: 20”  displayed to user which basically degrades the user experience.

3. We cannot debug Query Business Rule from Debug Security module but we can debug ACL from the same.

4. In ServiceNow the records are first queried and then after ACL rules are applied.

3.If we receive any email user should be created how can we achieve it?

You can quickly design a new email notification to run on sys_user table whenever a new record is "inserted". It will automatically be triggered whenever you add new users in sys_user table.

Please check and Mark Helpful and Correct if it really helps you.

Hey find your quick answers below:

1. After BR waits for server to response but Asyn does not wait for server to response and initiates its action.
eg: On clicking of submit 100 records should create, here if you use After BR, the form will keep on loading until 100 records are created but if you use Async it will get submitted immediately and 100 records will get created one by one. It will not keep you waiting in the form.

2. BR is data base operation and ACL is security rule to restrict access.

3. Create an inbound email action to create user records.

if you found it helpful please mark it.
