Disable FYI attachments when creating or changing a Purchase Order.

Summary:

Content (please ensure you mask any confidential information):

I need the FYI email to not include the PO attachment. 

I need my originator to not know the purchasing supplier and the purchase price.
I was able to activate the 24A template modification. 

But I need the attachment not to be sent. 

The attachment contains information that shouldn't be included.

I read everything up to the point where I activated the R&A modification. Then I wrote a SR and they asked me to ask here.

please, really i need Help.
