[Jibyjacob7]

I wanted to add a variable to dataset but its returning following error .

File_"&Period_Year";

ERROR: User does not have appropriate authorization level for library WC000002.

the variable is valid and when i add to the datastep  define a column it does work but when i add to the dataset.

Please show the full code. That line could be problematic in several ways depending on where it's used.

it worked when i added this let statement. %let period_year = &period_year ;

The ERROR means that you tried to create a dataset in a library where you do not have write permission.

Please post the complete log of your step, and use the </> button to post it.
