R3483 Running MPS generation with tomorrows date

Hi friends,

We have a situation. Running MPS for multi plant and then running MRP takes almost 4 hours. We would like to run it previous day and change the generation date to tomorrow.

We have conceptual design to pass a value from wrapper application so that the Processing option in R3483 generation date is taken tomorrows date.

Question :

1. If the generation date is manually enter for tomorrow's date, does that application works correctly as if it is run for tomorrow.

2. Is it advisable to change the PO Date in the code as system date+1

3. I looked into the performance issue document and what is the best way to run MRP with regeneration option
