Hi Steve:
The first part of your answer described a process so complex it would require an MIT graduate to understand. Oh wait, that's right - you genuinely are an MIT graduate!

But the second part of your answer appeals to my non-MIT mind. I checked and you are correct - in PO 9.2B the Sundry Items do have costs saved to the decimal places specified in the Company Profile. I re-read the Release Notes and found this change described at the bottom of page 4.
Thank you Steve.
