Hi Jeff, Thanks for the links and your suggestion. And for solving my problem 🙂 Stig

Thank you for the link, ChrisM@Work.

Also thank you to you, drew.allen. Also works well. Had - since this level of SQL is a bit beyond my present skill range - some difficulties running your query...

Thanks a lot. Works like a dream. I mark this as the solution because I can apply it directly to my subscription table. Now I just have to go learn...

Thank you for your answer once again. Now I have a good idea of the best option. Thank you.

Thank you for your reply. So far we are talking about approximately 40 users on a Server 2012. This may grow into the double over the next couple of years....

Thank you very much for your swift answer 🙂
