Yes, the TRIM() is gone. I had just copy pasted and edited your original but forgot to remove the TRIM(). Currently, there should not be many jobs running concurrently and as jobs get completed those records are removed, even when the number of users increase the number of records at any given moment will be low in the gttItemsSelected table. I will put in a note in the code nevertheless and if there are performance issues the first thing I will do is create the index.

Thanks a million for sorting this thing out for me and I am still reeling from the beauty of recursive CTE and it's implications of reporting ease.

Kindest regards
