How to avoid that series with identical values in consecutive time periods get rejected

[Liedo]

Some of the input time series happen to have the same value for all months of the year, so their behavior is not consistent with a stochastic process and therefore it cannot be modeled as such:

So the question is: is there a way to force the software to work with this kind of data?

[palatej]

We can force the software to model such series by unchecking the "preliminary checks" in the "series" option.
