I am getting following error while using an exogenous variable with X12.
I cant post the code here
any guesses with that may be the reason?
"ERROR: Starting date for the span of the data, . , must begin on or after the starting date for user defined regression

The span of any user-defined regression variables should include the span of the series to be seasonally adjusted, including backcasting or forecasting. For example, suppose that your user-defined regression variable has a span of [01JAN2017,31DEC2017], but your series has a span of [01JAN2016,31DEC2018], then the span of the data begins BEFORE the span of the regression variables.
