Odata Endpoint returned 400 Bad request

Hi, We are trying consume the OData Service from other App(that published the Odata). We are able to see the data while giving No to Authentication. But, we are getting this error while using the Authentication and  we are Authenticating by HTTPs Method (Username and Password). Is there any changes required in Authentication ? Thanks, Srini

Might not be the sollution but when we did an upgrade from Mx8 to Mx9 we encountered that some OData services where broken and gave a similair error. The problem was when you had read access of a reference to another entity but you did not have access at all on that other entity. Sollution was to either remove the read rights of that reference or give access to that other entity.
But I still do not know if this is a feature or a bug. You could argue both ways.
