We have a Tagtot built in Analysis, which is surprisingly decreasing in value when the source tag shows a decreasing trend. My understanding is that the tagtot will build a time integral which should always show a positive value as it will add to the previous value, unless of course the source values are all negative. The expectation is that when the source tag has all positive values, the totalizer should always ramp up or remain flat irrespective of the source decreasing or increasing.
Has anyone faced this before ? Any idea as to what may cause this behavior and how to change it ?
