Hi, I am having this warning:
10-27-2016 03:22 AM
Which procedure gave you that warning? Please supply the code.
And is there something to identify the 1327 observations (missing values etc)?

Usually a message like this means that there are observations with missing values that were dropped from the analysis. If you are using a FREQ statement, the WARNING tells you the sum of the frequencies for the observations that are dropped.
The easiest way to handle this is to pre-process the data to exclude observations that will be dropped. This is called restricting the data to "complete cases" or "listwise deletion." For ways to do this, see the artlcle "Complete cases: How to perform listwise deletion in SAS."
After you have filtered out the missing values, you can use PROC MEANS to count the remaining frequency count to decide if there is sufficient data left:
proc means data=CompleteCases sum; var freq; run;
