Problem with AB Trend Tool

[Meshal10]

Hi,

I have a problem with AB Trend, when I run the workflow this problem appears to me.

Does anyone know a solution to this problem?

Do you have enough data to perform the analysis? Also, is your AB Trend configured correctly for the test start date?

"The input data must have data for at least a year plus the number of periods prior to this date. For example for weekly data with 2 periods selected, you need 54 prior records in your data stream."
