Thank you for the reply.

I have taken a look at the PDF Reference
sixth edition
Adobe® Portable Document Format
So have all the other product developers out there that are trying to
sell their wares in the market place.

I have noted the plethora of products, offerings, hype and the like about accomlishing a very simple undertaking for PDF files(IMHO).

I do not want to take the ability to author PDF files away from Adobe - that is why i am using the Acrobat professional 9.0 Product in the first place - to author documents and to render them in a form that is useful to me.
I am hoping to use the PDF file to act as a human readable container to store what would otherwise be quite terse reading to the average person .

I am simply looking for the best approach - to solve a very clear-cut , real world problem such as this -
How to take the data I have ... in whatever form it comes to me in ... (this can vary greatly and be a mix of several forms depending on the source) - from CSV - to XML - to Excell spreadsheets , etc - and under program control - update a simple (I repeat - Simple ) PDF form - with a few Text boxes that are added for tracking specialized information and internal filing requirements , etc.

If there is a way to do this using the SDK - that would be great.
