I'm new to LimeSurvey.
I'm looking for a tool which I can use to create an internal survey.
The survey is meant as an evaluation of our customers.
Users would be requested to fill out a short survey for all actvive suppliers from our ERP system.
I guess it should be possible to create a dropdown list with all active suppliers - an SQL query from our ERP databse.
However, with LimeSurvey is there a way to prevent the same user from filling out the survey for the same supplier twice?
