Best way to use a word/PDF template in SAP

Hello guys,

I'm searching for the best and easiest way to use a word template in SAP where some fields should be filled from the SAP data. Therefor I use a custom report which should call/open the word/PDF template.

Normally I would say I would use a PDF form but I think this would be too much effort because 95% of the text is standard text, only 5% of the information should be filled individually.

So whats the best technique to get that filled?

Regards
Michael
