Locking concept in Detailed Scheduling Planning Board in SAP PPDS

[SAPSupport]

How to achieve that a Scheduler/Planner who gets onto any machine/resource (in the Detailed Scheduling Planning Board DSPB) for carrying out their scheduling activities, is locked for any further changes by any other scheduler to prevent duplicate changes on the same machine in the Planning board?

1. Follow recommendations given in SAP Note 575624 - Locking concept in APO PP/DS (documentation).

Note the following rules for running APO PP/DS with multiple users:

Save your changes frequently. You can then be sure that you are working on current data. In addition, fewer changes are made during every merge. This will improve system performance.
See SAP Note 513827 for the settings in MRP heuristics.
Make sure the responsibilities for individual projects and resources are clearly defined.

2. Check out further information about propagation range in the SAP Notes 397989 - PP/DS: Scheduling (Documentation) and 607428 - Product planning table - FAQs

The products and resources to be planned by the user are defined in the propagation range. The user does not have any change authorization for products and resources outside the propagation range. Users are requested to select a propagation range when they call the product planning table for the first time. This selection is necessary.
This is why you have to create the propagation ranges, which are to be used in the product planning table, before you call the product planning table for the first time.
The range is defined in the menu under "Production Planning -> Environment -> Current Settings -> Propagation Range".

I have a similar requirement & am not sure the mentioned note helped me any bit, when I read thru it. Did either of you have any luck with this requirement? I remember in the past, I had to activate a lock object via an enhancement/badi. Just can't recollect

Cheers
