the write method only get called for the model record update, you need to create a record, save it, edit it and save it again to get the write called

I meant that the overwritten function "create" is called when I want to create this record. Never wanted to say that I expect that the create function is called after an update. The create function contains the same functionality that I need for all updates. For creating a record it works, i.e. the function create is called. For updating my overwritten write function is not called.

I don't say that you need to call the write method in the create method, just that you need to do it in the ui to get the write method called, also you need to provide the code that you are using for because without that nobody will be able to see your error

Sorry, I am telling you two different things: 1. I create a record -> the inherited create method is called. --> works fine. 2. I want to edit this record --> the inherited write method is not called --> does not work fine. I didn't say that the write function shall be called within the create method. The two methods are completely independent. I'm just telling that the Inheritance worked for the create method but not for the write method. Kind regards.
