[SOLVED]Set attr from another BO in form without using shortcut

Hello all good helpers 🙂

Could anyone point me to how to go about to achieve this in AwareIM?

User chooses an ID on a form on BO1(got this one settled)
Check in BO2 which name belongs to this ID
Put this name from BO2 (or actually from BO1, but the same as I find in BO2) in the name attribute in the form for BO1

Challenge: can't use shortcut because I need the attr to be saved in BO1, not just show it on the form.

I'm lost, any advice would be greatly appreciated.

This is if you don't have references between the BOs at all:

Update rule in BO1. Dynamic.

If BO1.Idnumber WAS CHANGED Then
FIND BO2 WHERE (BO2.Idnumber=BO1.Idnumber)
BO1.Name=BO2.Name

If you do have an established reference between BO1 and BO2:

Update rule in BO1.

B01.Name=B01.B02.Name

(BO2 is the name of the actual reference in B01).

PERFECT! Just what I was looking for! Thank you so much! 😃
