Hi

I have a business rule which on validation has to check data that belongs to another business object.

Is it OK to use other business objects within business rules in order to check validity?

Example: (business rule code)

*Check if customer has any outstanding invoices
loRecordset = this.oInvoiceBizOBj.GetOpenInvoicesByCustomerID(tnId) && Access Invoice BizObj

*blah blah
.....etc.etc.

Is that good practice? or bad?

Thanks
Kev
