I was exploring SAS VA, and created a crosstab section. But the moment i found that there are no data in any intersaction that row disappears from the crosstab. But our management prefers that whether there are data or not, all the rows should be there in the crosstab, either with zero or missing value. I was managed to finally do that by inserting empty rows for all the combination. But the file size becomes very big. Other software (Tableau) that our office is also exploring have this capability with a simple menu option. So, i would suggest that SAS VA should incorporate this functionality so that we can do this kind of crosstab without restructing data.
