Identify all mandatory fields in Business Rule

[Sruthi17]

The Scenario is

When we move the change ticket from new to peer review, need to check if mandatory fields in the change tasks are filled

If the mandatory fields of the change tasks are not filled we need throw a error message

Is there any prebuilt function in servicenow server script to identify all the mandatory fields on a form

[ABHAY_M]

i think you have to handle those feild value is emty or not bby script in BR

like 
if(current.short_descrtion ==''''}
{

gs. add error mesasge

current.setabort action

}

Even I used the same in my script. So I wanted to know is there any other prebuilt function which does the same

Hi

You can use the nil() method of GlideElement API.

https://developer.servicenow.com/dev.do#!/reference/api/sandiego/server_legacy/c_GlideElementAPI#r_GlideElement-nil?navFilter=glideelement

If(current.assigned_to.nil()){

// Do Something

}

But the approach below will also work fine.

if(!current.assigned_to || current.assigned_to == ""){

// Do something

}

Please mark my answer as correct/helpful, if it helped

Thanks
