Hi Deepika,

Are you using in this in your Business Rule? 

var payload = {};
payload["u_correlation_id"] = current.sys_id.toString();

No Gayathri. could you please explain the process of this payload?

I am using BR for Incident Form's field only.

Hi,

Bi directional means exchanging of data between 2 instance, it could be servicenow- servicenow or servicenow- 3rd party tool.

Payload is like a container where in we need to put all the fiels which we need to exchange in that correlation id and correlation display is like unique identifiers.

For ex, if 2 snow instances are integrating and we need to exchange short description, priority to be sent from 1 snow to another snow.

we have to write BR, create payload and send details like short desc, priority, correlation id and correlation display, then another instance got these values and they can update it or do whatever with it.

Mark my answer helpful,if it helped you in any way.
