PRECONDITION_FAILED ETag error with My Appointments

Hi support,

I have a problem with My Appointments Fiori app subscribed in Hana Cloud Platform (Fiori Cloud Edition); when I try to update an appointment, oData service alwasy come back with "Precondition failed. Diagnosis ETag of the resource does not match to the given If_Match or If_None_Match conditions System Response Procedure Check the HTTP header parameters If_Match, If_None_Match of the request Procedure for System Administration" (see the screen);

It seems CRM_APPOINTMENT oData is not managing correctly the Data Concurrency (standard feature).

Our back-end system is compliant with sap help:

We extend both oData service (redefinition) and Fiori app (Extension mechanism), but we have the same error also with standard app.

Any hints?

Thank you,

    Following this post as even I face the same errors on GW Hub while using OData service for Desktop connection for SAP CRM.

    Manual workaround: Editing/making a small change for that appointment/entity in CRM removes the error which is very strange.
