Hello Andrey,
If you see processor numbers, i assume you managed to get "/SCWM/PL_LOAD - Load Planning and Simulation Results " working. After you run this session, you save which ever lines you want to plan and simulate. This creates a template for you.
Then open up "/SCWM/PL - Planning and Simulation". This is where you simulate planning. Create a copy of your template and adjust the numbers. Run planning and observe the change.
I love labor management, just sayin..
Best regards
Serhan
