Replaces the definition of an existing view.
- **Service:** [Views](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/index.md) `MFiles.IRPCViews`
- **gRPC method:** `/MFiles.IRPCViews/ModifyView`
- **HTTP (mf-http-grpc):** `POST /grpc/v1/modify-view`
- **Request:** [`ModifyViewRequest`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/ModifyView/index.md#request)
- **Response:** [`ModifyViewResponse`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/ModifyView/index.md#response)
- **Book and level:** Vault API, standard
- **Kind:** write
- **Session:** Required: a session (mfiles-session-id-bin metadata) or a session assertion (x-mf-session-assertion metadata).
- **Idempotent:** yes
- **Returns metadata structure version:** yes (in the mfiles-metadata-version-bin trailer)
- **Streaming:** none (unary)
## Remarks
- Send the complete view, identified by `id`: read it first, change what you need and send it
back.
- Private views need `manage_private_views`; common views (or turning a common view into a
private one, or the other way round) need `manage_common_views`. Only the owner can modify a
private view; for other users it fails with "Not found.".
- Some built-in views cannot be changed at all, for example 12, 13, 15, 16, 17, 18 and 23. Of
the views under Built-in (13) only the name and ACL can be changed, and of the views under
All object types (23) only the visualization.
- If the grouping levels change, child views that are inside the grouping levels are deleted.
- A common view can be made private only if all its child views are the caller's own private
views.
- The duplicate-name and indexing rules of [AddNewView](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/AddNewView/index.md)
apply. Vault event handlers for views run.
