I've tried to scavenge the internet for this but without any luck. I want to filter on a lookup-fields name value. According to the schema the property is a complex type of EntityReference. I have seen someone suggest (e.g. https://community.dynamics.com/crm/f/microsoft-dynamics-crm-forum/251843/odata-query-for-filter-on-basis-of-value-in-a-lookup-field-not-by-guid/702721 ) that it could be achieved using
/_odata/MyEntity/mylookupfield/Name eq 'somevalue'
Like you can using
/_odata/MyEntity/mylookupfield/Id eq guid'my-guid'
which works but I don't wont to filter by Id but rather the Name property. Is this the right way or is it even possible?
