To update work orders in SAP with the dates from your Primavera P3 schedule, you select the work orders on the P3 window and then click on the Transfer button on the P3 toolbar or use the Activities menu and select the Transfer menu option. Weavecentrix Desktop will then start to update your work orders schedule in SAP. Watch the status bar and the status light in both the SAP window and the P3 window to monitor the progress of your schedule update.

You must be logged in to SAP, logged in to P3 and have a P3 project open to be able to update the schedule dates in SAP.
The schedule dates in SAP are locked after you update them from Weavecentrix Desktop. Look at the section called SAP's DSEX System Status for an explanation of how this locking process works. If you need to unlock the schedule dates in a work order in SAP, review the section called Unlocking a Work order's SAP Schedule.
