TS Finite Heuristic - Static Period of supply

[Former Member]

I am trying to model build ahead (end item) using the static period of supply seems to be the only option available in Finite Heuristic to model Safety Days like behavior. I have set the Lot Sizing Procedure to 1 in Product Location and updated the SubPeriodsofSupply KF to 2.

Expected Result: demand from the 2 periods in the future to be pulled into the current period.

Actual Result: demand from the subsequent (1) period is pulled into the current period and not 2 periods as expected

(Link to SAP Help on Static Periods of Supply)

Lead Times Modeled: Production Lead Time is 1 week, Transportation Lead Time for components is 1 week

Am I missing any other MD setting?

Any help would be much appreciated.

Thanks,
Krish

Hello Krish,

what happens when you set 3 periods in SubPeriodsofSupply?
I assume you have not set key-figure SUBPERIODNUM so that the default of 1 subperiod is used.

If you still see strange effects, it'll be best if you open an incident so that the scenario can be checked in detail. Please attach the according diagnosis file to the incident.

Kind regards, Carsten

Hi Carsten,

The way I understand is that SUBPERIODNUM is for partial coverage of demand for future period (link). I started with just SUBPERIODSOFSUPPLY.. Check this attachment spsonly.png. In this case, from the receipts KF it looks like the value in subperiodofsupply includes current period + 1. The below note says the KF represents the number of subsequent periods. I understood this as just the future periods (not including current period)

Introducing SUBPERIODNUM in the model - Please Check the attachment subperiodnumb.png

Thanks,
Krish

Hello Krish,

the finite heuristic development colleagues could reproduce the issue and corrected it. The correction will be included in IBP 2008.
Sorry for the inconvience and thanks for the detailed testing!

Kind regards, Carsten

Thanks Carsten for your response and taking steps to fix the issue. I had trouble with both SUBPERIODSUPPLY and SUBPERIODNUM. Can you please tell me which one is being fixed?

The next functionality I am testing is using Non Delivery Transportation Rate to model Source Determination.

Thanks,

Krish

There happens a rounding error when the coverage range is computed. So it is a combination of both key-figures.

Cheeers, Carsten

Hi Krish,

Can you bring in Projected Stock KF in the view and share the screenshot?
