I would like to create ONE parameter that can accept more than one value. For example, I would like to have a parameter UserID. I would like to enter more than one user id when I am prompted for the parameter value. I do not want to create separate parameters as the user may not always need to enter more than one user id. Is there a way to create the parameter to allow this? I would expect the entry would be something like: userid1, userid2, userid3 And my SQL query would SELECT WHERE a.userid IN $P(UserID)
