## Description

**As a** project manager  
**I want to** automatically move a set of work packages to the earliest date possible  
**So that** I don't have to do this manually.

#### Acceptance criteria

##### Gantt view

  - If  a successor that is automatically scheduled can no longer derive its dates from the predecessor (i.e, because no predecessor has dates).
    
      - It remains in automatic mode, but loses its dates.

  - When a successor loses its one and only predecessor (i.e the last predecessor relationship is removed), the work package can no longer be in automatic mode.
    
      - Show a Primer confirmation: "This removes the the only predecessor, so the successor will automatically be switched to manual scheduling mode."
        
          - Actions: "Cancel" (secondary), "Remove" (danger)
    
      - The successor automatically switched to manual.

  - ~~If the dates of a predecessor of an automatically scheduled work package are removed, and the successor has dates, the successor should go into manual mode. But we need to ask the user for confirmation:~~
    
      - ~~"This work package has at least one automatically scheduled successor. Removing the dates here will switch the successor to manual scheduling to preserve its dates."~~

  - ~~If all predecessors of an automatically scheduled work package are deleted:~~
    
      - ~~If the successor has dates, it should switch to manual mode. User confirmation is asked:~~
        
          - ~~"This work package has at least one automatically scheduled successor. Deleting this work package will switch the successor to manual scheduling to preserve its dates."~~
    
      - ~~The relation is deleted~~
