Need to avoid the Un initialized note while working with condition though if the variable missinng

ambadi007 — Mon, 17 Feb 2020 14:34:28 GMT

Hi Experts,

I have a data set and usually it will have variables Type1 Type2 Type3, but unfortunately this time there is no variables like that, so now if i am working on the below

if Type1 = "1" then label= "Type1";

else label= "NA";

f Type1 = "2" then label= "Type2";

else label= "NA";

etc....

so this time I am getting un initialized note, is there any way to avoid this? Need and needs this to run in future also with out any changes if the variable added next delivery by the data team.

NOTE: VAriable Type1 is uninitialized
NOTE: VAriable Type2 is uninitialized
NOTE: VAriable Type3 is uninitialized

The variables Type1 Type2 Type3 is getting this note , due to this time these are not available

Explain how you use the variables when they exist. If they don't exist is the scenario simply the same as when they exist but all values are missing?

Could you achieve the same result if you define TYPE1-TYPE3.

data test;
   length type1-type3 $1;
   call missing(of type:);
   set ...;
   <the rest>
   run;

Why do you check variables that don't exist in the data set? What meaning does it have?

Why do you want to avoid the note? The note is raising a valid point: the data expected by the program is not there.

If you always want the variables to be there, @data_null__ 's recommendation is the way to go.

But don't be surprised if this absent data causes issues later on and the issue goes undetected.
