Data _null_ is also used to produce complex reports which cannot be customized in proc report.Proc doesnt allow us to use if statements where in data null we can use if statements to get the desired output.For example if you want multiple sub totals or if you want to print footnote only at the end of a page break.This is useful specially for pdf reports.

I need help in merging two different datasets. I am merging by date and I want to propagate observations from one dataset to the corresponding dates. One dataset has a unique date for each day of the month, while the other dataset has same date for different patient visits. For example I want to spread an observation on the 31DEC2008 from one dataset to several observations with the same date on a second dataset for all the patients who visited on that date. I have tried to merge the two and the result is not what I wanted. Instead I get a dataset whereby all the dates have missing values where observations from the first datset should have spread.
