Use this window to define variability categories. A range of coefficients of variability of a part type belongs to a specific variability category with a specific variability factor. Variability category is used when determining the buffer sizes of the parts defined as buffered parts.
Note: variability is measured during the rolling time horizon for historical ADU, which is determined by the lead time category for the part. If this time horizon is longer than the time with issue transactions for the part, you should set the variability category manually, since the measured variability will be unrealistically high.
