Questions for merging datasets

[233]

Hi,

I have two datasets, one is about sale of beer and another is about sale of snacks.

The two datasets have the same variables but different values, and below are part of data from beer data set.

I'm a newbie and not quite familiar with many procedures.

I was wondering is there a procedure  I could use to let me point out which part of data is from beer and which part of data is from snack after I merge the two datasets? Could I create a categorical variable and maybe use some procedures to point out each row represents the sale from beer or snack? Any suggestions will be really appreciate!

You don't merge them, you stack them, and you can use several "tricks" to determine the "type":

data want;
set
  beer
  snacks
  indsname=dsname
;
product = dsname;
run;

Alternatively, you can use in= dataset options and evaluate the variables from there to set your product.

I have successfully add the name of dataset beside the variable. Thank you so much!
