It seems you have posted the same question in two groups, here and in https://communities.sas.com/t5/Base-SAS-Programming/Need-to-check-seasonality-across-the-month-varia...
Unless your question is about seasonality using SAS Visual Analytics, I suggest you to delete this post and someone can assist in your other post.

For the analysis of seasonality I suggest to look into PROC X11 and PROC X13 (formerly X12) which are part of SAS/ETS. They offer a wide range of analysis and detection methods for seasonality in your data. The online help contains some examples for that.
For smoothing of your data you might want to take a look at the EXPAND procedure of SAS/ETS.
