Re: Dynamic Safety Stock

Hi MM KS,

If you repeat your calculation, you will get this:

1. Forecast in the past , safety stock does not apply, system generated PR enough to cover need
2. Oct: Forecast next 13 weeks 400 / 62 days = 6.4516 per day *30 days = 193.55 safety stock +100 normal req =293.55 PR - OH = 293.55 PR
3. Nov: Forecast next 13 weeks 300 / 61 days = 4.918 per day *30 days = 147.54 safety stock +100 normal req = 247.54  - 193.55 qty = 53.91  - OH = 53.91 PR
4. Dec: Forecast next 13 weeks 300 / 63 days = 4.762 per
   day *30 days = 142.86 safety stock +100 normal req =242.85  - 147.54 qty - OH = 95.32 PR
5. Jan: Forecast next 13 weeks 300 / 64 days = 4.687 per
   day *30 days = 140.63 safety stock +100 normal req =240.63  - 142.86 qty - OH = 97.78 PR
6. Feb: Forecast next 13 weeks 400 / 65 days = 6.1539 per day *30 days = 184.615 safety stock +100 normal req = 284.615  - 140.63 qty - OH = 143.98 PR

The system is considering 400 EA for February calculation, this is maybe because February has less days, and then 13 weeks cover still May 3rd...Look at the weeks:

Note that you have forecast in Feb 2nd, Mar 2nd, Apr 1st and May 1st. 

Kind Regards,
