how far to set the period split for the transfer to demand management

[Former Member]

We had the period split (from monthly forecast to weekly PIR) set at the 6 months. But it generated spikes in requirements around the 6th month. If we want to maintain the all the PIRs in weekly bucket within 1 year, it would require us to change the period split setting to beyond 12 months. The change would impact the MRP performance due to the data volume increase. i am wondering what the optimal period split setting should we use. What do other companies set for the period split for transfer to demand management? thanks.

Hi,

Before directly using it to release in /sapapo/mc90 or in background job, you can check it using the period split simulator which is at the top in /sapapo/sdp_extr. You can give date range, random value of forecast to be splitted and also the calendar to be used. Distribution function is what decides how value is split within the period(in your case it's week). So use this functionality.

Remember in background jobs you can't give dates, planning horizon is taken into account. The "No of periods" in the period split profile plays a crucial role in background job.

If more value is released(spikes i think in your terms) then forecast is more i think in 6th month.

Hope this helps.

Thanks and Regards,

Nithin.

Hi,

First of all, I am not sure why the spike is taking place.

Kindly attach a "distribution Function" to the Period split profile and check the results. If it helps in removing skewness, kindly revert.
