Hi @sawantshubham 

Its tough to generalize the question as it depends which type of business rule, what type of client script or type of Ui policy like load/change etc..

Here is the article by @MPD Odijk you can refer to know execution order:

Thanks and Regards,

Hi @sawantshubham ,

 

Execution in ServiceNow always starts with ACLs to validate access. If access is allowed, Business Rules run on the server (Before, then the database action, followed by After and Async rules). Once the data reaches the client, UI Policies execute first, followed by Client Scripts to handle client-side behavior.

Execution order:
ACLs - Business Rules (Before -DB Action -After -Async) - UI Policies -Client Scripts

If this response helps you solve the issue, please mark it as the Accepted Solution.

Thanks and Regards,

AnkaRao
