Forum Post: RE: OData Service Call return 404 and syntax while loading ODataPath String

Hi, there are couple of issue in your odata query, as you are using the custom entity the attribute names are not correct you have mentioned address,BPMA,bpmalocationId,BrandedMarketerid,city,parentjdenumber,SiteNumber, but it should be like chs_address chs_xyz etc also you are passing the locationid dynamically but have mentioned as string 'locationId' try below query : var ODataPath = serverUrl + " /xrmservices/2011/OrganizationData.svc/chs_bpmalocationSet?$select=bpmalocationId,statecode,&$filter=bpmalocationId eq guid'" + locationId;
