I am trying to understand and find out what are the different techniques commonly used to Caps and floor outliers present in a dataset? Any guidance/research paper link is greatly appreciated?

Take a look at the Replacement node in SAS Enterprise miner. It does not remove outliers the way the Filter node would.
By default the limit method is based on a standard deviation from the mean. Take a look at the flooring and capping that happens by default. There is also a brief example of how to use the replacement editor in the reference help (press F1 and go to the Replacement node under the Modify sections).
