Distribution Profile
The probability distribution used for a given pipeline forecast and variance, and threshold global settings of high/low volume, and high/low variance of the pipeline forecasts.
For low volume with low variance, “Poisson” distribution is used
For low volume with high variance, “Negative Binomial” distribution is used
For high volume, “Normal” distribution is mostly used. If the IO_COV_THRESHOLD_NORMAL_TO_NEGBINOM global setting has a value >= 0, and the SKU’s COV exceeds this global setting, then “Negative Binomial” distribution is used, and the distribution profile shows “Negative Binomial (High Volume)”
Comparison fields 
For comparison fields, there are three values shown per field:
(A) — The value from the first scenario selection
(B) — The value from the compare scenario selection
(Delta) — The difference between the two selections
