Thank you for contacting us.
It appears that this is not an issue with the latest Enterprise 7.2 release. Marking the "Do not put the Record Details in Mail Body" option does indeed remove the details from the Purchase Order from the email's text (in which case only a PDF copy of the Purchase Order is attached to the email).
Please consider updating to the latest 7.2 version of the software.
Regards,
The HansaWorld Support Team
