Hello,
I have a feature class containing subtypes in a dataset (from a Utility network) and another feature class without subtypes in another dataset.
I added a relationship class between both FS, and it is working.
Now I want to restrict relationship with rules, so that I can add relations only for some subtypes.
I added relationship class rules so that only one subtype (HTA câble) can have relation with MT_PROFE feature class :

However, once I use the feature service, I can still add an MT_PROF in relation with other subtypes
Here you can see a subtype "BT Câble" in relation with an MT_PROFE, which is not allowed :

I tried to restart and even republish web service.
Any idea ?
