Mariano’s latest post explains how to add more comment lines to POP Purchase Order report. The idea is to split the comment text into 80 characters sized fields and then displaying it on separate report sections. I leave you here so you could refer to this awesome piece of post from Mariano. It’s a step-by-step guide on how to do this.
David, way back in 2011, demonstrated a similar approach on his post about adding more comment lines on SOP Documents. It’s worth to remind that post now.
