As or Release 4.6A, personnel planning data will be transferred to Controlling automatically. The controller can decide to which target version the data should be transferred. You can:
Specify an end date for every CO version. The R/3 System transfers the data to this version only up to this key date.
You make the version assignments in Customizing for Controlling by choosing Planning -> R/3 Internal Planning Data Transfer -> Transfer Personnel Costs from HR (as of Release 46A).
