I have a similar issue but I am using PROC X13 instead. proc x13 data = testdata date=DATE interval=MONTH plots=none; var USMTO_Units; transform function=log; adjust predefined=LOM; /* use SAS predefined length of month adjustment */ regression uservar=imts / usertype=AO; automdl; x11 outforecast; forecast lead = 24; output out=x13v3_output a1 d11; run; I have data for the variable of interest from Jan1996 to Feb2016. In the table "testdata" I have data for regressor variable IMTS from Jan1996 to Feb2018. I have been trying to get SAS to include the forecast for USMTO_Units in the table "x13v3_output" but without success, can anyone help? Thanks, Michael
