Jira Asset Append Attributes from referenced objects

[Manuel Probst]

Hi,

i have several objects and i want to show some attributes of an "mother" (aaaa) object in another object. 

with the given attributes:

Now i have child object, called "testumgebung", which is already referenced to the "mother" object aaaa

Target is: i will choose a customer out of the reference field testumgebung.customer - which works fine, but the in the field testumgebung.admin_AP shall occur aaaa.Kürzel from the "mother" object.

What did i try:

My approach is using the automation rule:

ruel --> When (object created/update) --> if (ObjectType = "testumgebung") --> then (action: attribut; name: admin_AP; value: {{object."aaaa".Kürzel}} 

i tried different combination of the object reference, but everythem the value in the field get "{{object."aaaa".Kürzel}} but never the value of referenced object in aaaa

What do I do wrong
