I would like to write something like this:
data want; set have (drop=pk_: fk_: bk_:); run;
The problem occurs when there is no variable that starts with fk_, is it possible to set it conditionally (with out necessity to write macro that checks whether variable exists in a given file)? Thanks
You can insert this line before your DATA step:
options dkricond=NoWarn;
Then after the DATA step, switch back to the one that you prefer:
options dkricond=Warn;
options dkricond=Error;
Think of this as Drop Keep Rename on Input Condition.
