I have in an itemtype a Foreign property and the referred property is a foreign property in another itemtype. In the form of the itemtype the data source results undefined. How can I resolve?

Hi Guido,

not sure if multiple nested foreign properties can work at all.

A foreign property is just a link to another property. The property itself doesn´t store any information and is empty in the database. When you now reference to this "empty" property, Innovator will not see any data. But I have to admit that I never have tried this one on my own.

As alternative you maybe can use the Federated DataType and use a Method to populate the data. 

in Aras 10 it was working, now with Aras 12 in result udefined

Out of interest I made a quick test in my Innovator 12.

I added a foreign property "test" in Manufacturer Part to link a property from Manufacturer to Manufacturer Part.

Then I added a foreign property in Part AML to link the "test" property from Manufacturer Part into "Part AML". This one worked for me!
