I came across a strange problem today when trying to use the Ago time series function. I made a simple formula to show the change in a measure between current month and last month. Easy you would think:
Folder.Measure – Ago(Folder.Measure, DateFolder.Month, 1)
However, this resulted in:
[nQSError: 59012] UnderFlow occurred during the execution of SubtractUInt32.
Eh? I got around the problem by multiplying each side of the formula by 1.0. Not sure why this was needed but it seemed to do the trick. Hopefully this’ll help you if you arrived here via a search engine.
