I'm following this article https://community.webcon.com/posts/post/approval-process-on-the-item-list-with-row-blocking/138 in order to block rows. I've managed to give access to items list only users mentioned in one of the columns of item list using SQL against BPS Users list (see picture attached) , but all rows are available to everyone from this column, not only one row per one user.
What am I doing wrong?
