Which BO do I put my rule to compute Total

BLOMASKY

Assume I have a Customer BO with an attribute TotalOwed thats calculated.
The Invoice BO is owned by customer and has an attribute LineTotal

I want the TotalOwed in the Customer BO to always be the SUM of the LineTotal for the customers Invoices.

So my question,
1) Do I put the rule in the Customer with the logic:
IF Invoices FROM Customer.MyInvoices WAS CHANGED Then Customer.TotalOwed = SUM Invoice.LineTotal where Invoice IN Customer.MyInvoices

or
2) put the rule in the Invoice BO with the logic:
IF Invoice.LineTotal WAS CHANGED then Invoice.Customer.TotalOwed = ......

Thanks

Customer.TotalOwed = SUM Invoice.LineTotal where Invoice IN Customer.MyInvoices

Just put this rule in the Customer & it will stay up to date. Magic!

Tom, I don't just believe in Magic, I rely on Magic! (Wait, I used to. Now I rely on Aware!, or perhaps I should say I am AWARE of Magic of AWARE!)

Hi Tom... If you put the rule on Customer Then I Assume the 'Do Not Check Referred Attributes' Flag must be left unticked? Or will it still trigger if that flag is ticked?

Yes, that's my understanding.
