A timeout defines the amount of time a task will wait to complete an action before processing continues.
If you deploy a process that has a screenflow, you need to consider that some timeout settings are available in the Process Administrator. You can set the BP-Method timeout and the Interactive component timeout
In a screenflow you can combine different types of activities and timeouts apply for each activity or group of them. In the following example the BP-Method timeout is set to 60 seconds and the Interactive component timeout is set to 720 minutes.

Once the screenflow begins to execute, the first 3 automatic activities (Auto 1, Auto 2, and Auto3), will have a total timeout of 60 seconds. When an interactive activity is reached, the Maximum BP-Methods timeout is reset.
Then the Interactive Component Call activity, Interactive 1, begins to execute. The user has 720 minutes maximum to complete the task.
To complete the screenflow, the Auto 4 activity executes and has 60 seconds to complete its execution.
