Ive been adding a couple of documents to various products so they autogenerate at invoicing.

In particular to 1 product I added 2 Patient Letters not forms.  

My impression is that at creation time the Letters are created with the clinician name / start time and any future changes to those parameters wont change the letter.  IE it is not dynamic into the future...this is good for documents that you want hard copied on file and not changed.  All though they do support versions but past versions are available.  Patient Letters also seem to support the input of dynamic fields at document creation

Forms on the other hand are dynamic at creation and into the future ie...if I create a form with Clinician A but latter edit the form in the medical record view to be owned by cliniciam B the form will dynamically update.  

Ive noticed that if I select letters in the product attachments they are added more like a form.

EG A letter template (presented as a ODT file) is added manually, will usually have the letter odt attachment as well as a pdf icon to chose from in the medical record view.  However the same letter when added automatically via a product sale...will only be viewable as a pdf.

I assume this is because we cant display the dynamic field window for letters at the time of invoicing or soon after.  Any work arounds apart from the manual add?

This applies to 1.5.1 I have not investigated this in 1.6

Thanks for any input.
