IGNOREDEPLOCDEM = X on Location-Product, not considered by optimizer

[former_member602633]

Hello IBP Guru's,

We are using TS Based Supply Optimizer.

We have a requirement to ignore the Dependent Location Demand when we calculate the Additional Lot Size Demand using Target Subperiods of Supply (Static Lot Size Procedure = 1). But if we set the Ignore Dependent Location Demand = X in Location-Product, the Dependent Demand still considers Dependent Customer Demand + Dependent Location Demand, while it should only consider Dependent Customer Demand.

Is there a way to use Target Subperiods of Supply without considering the Dependent Location Demand?

Any insights is really appreciated.

Thanks,

Mangesh

Hello All,

Thanks for all the good responses. We have escalated this issue to SAP and the development team is looking into this. The behavior is different in Infinite Heuristics and Optimizer with the IGNOREDEPLOCDEM = X is set. The development team has acknowledged that this needs to be corrected and they are looking into fixing it.

The Additional Lot Size Demand should be calculated based on only Dependent Customer Demand and should ignore Dependent Location Demand, when the parameter IGNOREDEPLOCDEM = X is set.

Thanks again for all the valuable feedback.

Regards,

Mangesh

Hello ocmangeshrk

The behaviour that you mentioned in right. If you put X in ignore dependent location demand the algorithm ignores the dependent location demand value. But the additional lot size policy will consider both dependent location and depdendent customer demand. The DRP algorithm and the safety stock determination based on sub period of supply are technically 2 different function module, although they work in tandem.The issue is the additional lot size policy calculation refers to INDEPENDENTDEMAND and DEPENDENTDEMAND KFs,which are at PRODLOC level, whereas dependent location demand and depdendent customer demand are altogether at diferent planning level.Their is a way thru which you can model your requirement. Below are the steps to do so.

• Create a new KF(e.g KF1) to bring the depdendent customer demand at PRODLOC level.
• Create another KF (e.g KF1) that will sum INDEPENDENTDEMAND + KF1 at PRODLOC level
• Assuming that you have maintained SUBPERIODOFSUPPLY & No of Subperiod KF, create 1 more KF (e.g KF3), where you right the coverage function and derive the qty value of the safety stock requirement.
• Either copy the value of KF3 to INVENTORYTARGET KF or make the INVENTORYTARGET KF calulated and refer to KF3 as input.

Hope this helps

Hi Mangesh,

It should work, check if your setup again if all looks good then raise OSS

Thanks

Thanks Girish.

It is not working and we have created an OSS message. Have you implemented this scenario?

[former_member654033]

I think I have tested this but its long time now when I tested this scenario. Should work
