How to get the Body layout in the body of the Purchase Order Email communication sent to the vendor?

Hi Oracle Savvy's,

Can someone guide me that I want to customize the Email communication that is sent to the vendors.

I was able to customize the Purchase Order Email Subject Layout and Purchase Order Email Body Layout.

But I am able to select only one default layout in the analytics and what happens is the subject content is being Transferred to the body layout.

If I select the Body layout then that comes in the subject as well.

How can I have the Subject layout content in the subject email and Body layout content in the body of the email?
