When trying to POST data into either the Dimensions or DimensionValues entity/page in Business Central via an extended API I am currently receiving the following error:

{"error":{"code":"BadRequest_MethodNotAllowed","message":"Entity does not support insert.  CorrelationId:  ea271873-4a4a-4992-ab98-1e98aa87aa07."}}

Is this due to the settings corresponding to the entity, if so what are the steps in order to allow insert or editable in BC to a particular entity?
