Changing item dimension

Any thoughts on this post about changing an item’s dimension once it already has transactions.

We want to change the dimensions on many different items. Would this method work for the most part?

Any comments?

As the poster states:

This post is purely experimental, and I am currently assessing the feasibility of it, so please be very critical of it. I’m looking for feedback on issues I’ve not yet thought of.

So I suggest that you test the experimental code, see how you get on and post back [:D]
