The PrgInitiateReplan client API opens the Initiate Replan dialog box where you can specify which hierarchy levels you want to apply a replan to. Once you have specified the hierarchies the replay will apply to, you are prompted to provide replan dates for the project. This client API uses no parameters.
The PrgInitiateReplan method uses the PrgInitiateReplan client API to open the Initiate Replan dialog box.
