Procedure
The R/3 PS Logon dialog box appears. Here you have to log on to the current R/3 System again. This is necessary for technical reasons.

If this is the first time you have used Open PS for Microsoft Project, you have to enter your user and system data. A wizard helps you do this.
For more information about the initial settings for Open PS, refer to the Open PS for Microsoft Project documentation that you downloaded with Open PS.

Storing Data in the Storage System of the Knowledge Provider.
Result
The system generates a MPP file that is displayed in the browser as an extra object. This MPP must be included in the selection when
Selecting Substructures of the Controlled Object.
