# Project Lock Action With the help of the Project Lock Action it is possible to lock a project, for example via a stream that is triggered by the "open\_project" trigger. This is possible for any type of project in Helmut, and can be used in two different ways. Simple locking, which indicates that the project has already been opened by a user, and forced locking, in which the project can definitely no longer be opened by other users until it has been unlocked. Unlock can also be carried out by another user, depending on the access rights, or takes place as soon as the project is closed. A project can also be locked even though it is not open, for example because the project should no longer be edited after a defined process has been completed, etc. The Project import Action can be queried in every stream in which a project object is present, or if the ProjectID is known. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.helmut.de/helmut4-releases/v4.6.1/helmut4-components/streamdesigner/nodes/actions/project/project-lock-action.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
