IBP Optimizer splits confirmed receipts to equal daily amounts

[former_member812673]

Hello all,

I am trying to set up two different planning versions, one with daily buckets and one with weekly buckets. I am planning the first 5 weeks on the daily buckets and copy this result to the weekly planning version with the use of the production freeze horizon to get confirmed production receipts.

My problem is the optimizer that runs with the weekly buckets. As you can see in the screenshot, the optimizer splits the confirmed receipts to an equal amount each day of the week. That would lead to wrong planned orders when we integrate the weekly planning to ECC.

Has someone faced similar problems? Is it possible to avoid the split and keep the receipts on the confirmed day even with weekly buckets?

Thanks

Hi Katja,

The algorithm did as expected. If you run in the weekly bucket, the algorithm will consider the weekly confirmed production value which is aggregated from the daily bucket. Moreover, there are no values in the detail level so it disaggregates proportionally to 7 days. If you want the system to disaggregate differently please configure the disaggregation logic or why not interface the daily bucket optimizer results to ECC for the first 5 weeks of production frozen horizon while keeping the weekly bucket optimizer as a mid-term/long-term supply planning.

Hope this helps

Hello Katja,

when the optimizer is run with weekly periods it only sees the aggregated confirmed productions on a weekly level, i.e. it does not know that it was on 05/23/2022 as in your example. It also computes only one production value for the week that is disaggregated afterwards to days.

Please check Aggregation and Disaggregation Across Different Time Levels for more information.

Kind regards, Carsten
