Charles,

That’s amazing but it’s not quite there. If I select the lines where rownbr
= 1, I eliminate the list from customer 3, but I also lose the first line
from customer 2

So? That's what you asked for...the first line for customer 2 had T1/C1
which was already shown for Customer 1
"4 customers but only 3 distinct combinations of Type and Code."
