No entries found for list of values while running Purchase Order print report

One of the Inventory user was getting the below error "No list of values error" while running purchase order print report"

We have given the same responsibility to 3 users and 2 of them were able to run the report successfully but only one user was reporting the above error.

I checked responsibility and users every thing was looking fine but when i checked their EBS userids then came to know the user who is getting the error was not defined as an employee in Purchasing Super user ====> Setup===> Employee. Either to define employee in HR or in Purchasing and we are using purchasing to define the employees

Once i defined the employee and tagged the same employee name in User creation form like below screen , our issue was resolved :)
