There are several potential causes for this occurrence:\n\n-\n The field or fields that are referenced in the warning exist only in [Development Mode](/looker/docs/dev-mode-prod-mode#development_mode), and you're viewing the Explore or Look in [Production Mode](/looker/docs/dev-mode-prod-mode#production_mode) (or vice versa).\n\n-\n A [join](/looker/docs/reference/param-explore-join) was removed from the [`explore` file's LookML definition](/looker/docs/reference/param-explore-explore), which removed the field that is referenced in the warning.\n\n For example, if you see the warning `users.name no longer exists on Companies, and will be ignored`, this may indicate that the `users` view and its fields are no longer joined to the `companies` Explore and are therefore unavailable in the Look or Explore.\n \u003e You can use the [metadata panel in the IDE](/looker/docs/lookml-metadata#metadata_for_views) to see all `explore` definitions that reference a specific view.\n-\n A change was made to the view's name in its [file](/looker/docs/model-and-view-files#view_files), or the view reference in the `explore` LookML definition was changed with a parameter such as [`view_name`](/looker/docs/reference/param-explore-view-name).\n\n\n For example, an underlying view for an Explore called `users`\n was updated with a `view_name` parameter that references a view called `customers`: \n\n ```\n explore: users {\n view_name: customers\n }\n \n ```\n\nResolving the warning if fields that are referenced in the warning were deleted intentionally\n---------------------------------------------------------------------------------------------\n\n\nIf a field that is referenced in a warning was *intentionally* removed by a LookML developer, follow these steps to resolve the warning for either a Look or an Explore.\n\n### Resolving the warning for a Look\n\n\nTo resolve the `view_name.field_name no longer exists on explore_name and will be ignored` warning for a Look:\n\n1. Select the **Edit** button in the top right corner to [edit the Look.](/looker/docs/saving-and-editing-looks#editing_looks)\n2. Once in edit mode, select the **x** next to each error message to clear the warning.\n3. Make a change, such as [adding](/looker/docs/creating-and-editing-explores#adding_more_dimensions_for_more_detail) any field from the field picker and then [removing](/looker/docs/creating-and-editing-explores#removing_fields) it, to activate the **Save** button.\n4. Select **Save**.\n\n\u003cbr /\u003e\n\n\nThis will update and save the Look to omit the deleted field or fields and the accompanying errors.\n\n### Resolving the warning for an Explore\n\n\nTo resolve the `view_name.field_name no longer exists on explore_name and will be ignored` warning for an Explore:\n\n1. Make a change, such as [adding](/looker/docs/creating-and-editing-explores#adding_more_dimensions_for_more_detail) any field from the field picker and then [removing](/looker/docs/creating-and-editing-explores#removing_fields) it.\n2. Select **Run** to rerun the Explore query.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e"]]
