SAP RAP - Determination of on modify is not triggered during change

[PaulRintisch]

Dear SAP Community,

currently I´m trying to implement a determination with on modify into my RAP Application. So far so good, but the defined ABAP Method is only called while pressing save.

As far as I´ve understood the documentation and blog post, "on modify" will instantly being triggered, as soon as the definition is fulfilled. The handling is happening in the transactional buffer - So it should work without pressing save, right?

  determination detCreateValues on modify { create; }
  determination onChangeEQUNR on modify { field equnr; }

I´ve also implemented SideEffects in my UI for the field, but the ABAP Method is still not triggered

Can somehelp give me a solution for it? Maybe I understood something wrong

Notes:
HANA2020 Release
Non Draft Application

Thank you very much, I wasn´t aware of that. Will try it out when I´m enabling Draft in my App. Thanks
