I have a little Problem. I'm trying to do the following. There is a Field on SharePoint List items called HasUniqueRoleAssignments that is hidden on a standard REST call. If I put it in the select string of the rest call I will retrieve it. So far so good. But what I apperently can't do is use it in the filter statement. So the URL
.../sites/site/_api/web/lists/getbytitle('Listname')/items?$filter=(Some_Standard_Field%20eq%20%27139%27)&$select=Id,HasUniqueRoleAssignments,Author/Title,Editor/Title,Created,Some_Standard_FieldId&$expand=Author,Editor&$top=1000
will work just fine. But if I try
.../sites/site/_api/web/lists/getbytitle('Listname')/items?$filter=(HasUniqueRoleAssignments%20eq%20%27false%27)&$select=Id,HasUniqueRoleAssignments&$top=1000
the request will fail with the error message, that the column HasUniqueRoleAssignments is not available.
Does anyone have an idea, how to use the filter to get items with
HasUniqueRoleAssignments = false or true?
Would be thankful for help
