the original dataset has date variables are listed as 20051001, 20160705
would you please recommend how to convert them to sas date
FORMAT date date9.; date= input(date, yymmdd10.);

You can't change a variable type in place, you need to recreate a new variable.
FORMAT date_new date9.; date_new= input(date, yymmdd10.);

sorry, my previous message was not clear
i did the same way as you said,
with a new variable
but the new varabile has all missing values
the date format is yyyymmdd, like 20160705, i do not know how to convert

Use the yymmdd8. format in the input function.
Also post the log of the data step.

Possibly. It's more likely you had some other issue and running from the beginning fixed it.
This is especially true if your in the habit of naming your output the same at the dataset in your SET statement.
