Hi Nadya,
Good to see you too :-) (Funny, I thought you would be the first person to reply to my first ever message on UT)
Possibly triggers can do the job. I will look into that. But I thought about another approach, right after I posted my initial message. I am thinking about creating a view with a calculated field. I have never had a view with a calculated field on sum in another table so I don't know if it will work. I know by the end of the day I will know if it works.
Thank you for your helpful suggestion.
Dima
