Hi Hilmar,

Thank you. I've thought about this solution, but I was looking for something that just working with that code (with some adjusts, of course)...

I have one little question: Do you have it working in production, don't you? ... So, if yes, have you had some problems with wrong calculates? I'm afraid about keep wrong information on Table_A. If it happens, I'm really in trouble!

I did a lot of tests, and it works... I'm asking just for be sure to delivery this solution for my clients! ;-)

Thank you, so much! ....
