Proc Logistic offset= value not saving in outmodel= coefficients file

[RobertNYC]

I’m using an offset variable in some model builds and I am trying to output the coefficients in order to score datasets for automated scoring.  When I go to score the data it seems like the offset value is not saving in the coefficients file. 

In the past, when I have used the WEIGHT option, I never had this problem. 

Is there I when to save the offset value without having to calculate the  “off”  variable everytime I score data?

proc logistic data= training outmodel= mod.MYMODEL descending;
model target=  
sales_ratiod
AGE_GT45
EM
RECENCY
PURCHASE_ORDERS
X_division
INDL_BT
WEEKEND_SHOPPER
/ offset=off   ; 
output predicted=p_response; run; quit;
 
 
 
proc logistic inmodel=MYMODEL   ;
score data= MYDATA  out=SCORED_DATA;
run;
 
ERROR: Variable off not found in DATA=MYMODEL  
NOTE: The SAS System stopped processing this step because of errors.

OFFSET may be a fixed value for you, but in the program it's designed to accept a variable. So it's not being treated as a constant, which is why it needs to be specified in the scoring data as well. It could be different values dependent on input variables for example.

Could you try SCORE statement in PROC LOGISTIC.

proc logistic data= training outmodel= mod.MYMODEL descending;
model target=  
sales_ratiod
AGE_GT45
EM
RECENCY
PURCHASE_ORDERS
X_division
INDL_BT
WEEKEND_SHOPPER
/ offset=off   ; 

score data= MYDATA  out=SCORED_DATA;
run;

Thanks Ksharp, 

Unfortunately, the off var still did not  save in the coefficients file.

The offset variable is essentially a predictor variable in the model.  Any data that you want to score has to have values of the model predictors, so the offset has to be available.
