Andrew,
I have been at this company for 8 years and we ALWAYS have let items go to negative. We have never seen this problem.

btw the other instance that I reported we found was correct. The average cost was at 120 and standard at 0 so in essence we created that problem.

The instance originally reported can not be explained. Other than we used Adagio.

We are tracking our costing now when it hits the GL so we can reverse the erroneous entries. I will keep you abreast of my progress uncovering the problem.
