Hi Yash,
Is the heuristic creating real surplus (Available Quantity > 0 at the last entry in the Elements tab) or only creating orders earlier than required?
- If available quantity = 0 at the end of the horizon, you may want to switch to method FIFO for Net Requirements Calculation in the heuristic settings
- If you want to use Avoid Surpluses method, consider KBA below:
2010195 Avoid surplus receipts in PPDS planning by setting Alert Threshold in product m
Apart from this, check lot-size settings, as recommended by Vikash and Marius above.
Regards,
Tiago
