Hello,
I now have 2 entities created,
which is product (product ID as primary field, price...etc) and Order (relation with product, order qty...etc)
What I would like to do is to set a field "totalprice" in Order, which should be order qty multiplied by "price" in product entity.
I tried to do this by set up a business rule, though in the edit GUI I couldn't refer the price.
Could anyone give me some advice about this kind of calculation?
Thank you very much!
Best Regards,
