Calculation of dependent demand

Hi,

We are able to calculate the Consensus Demand. We are working on a copy of SAP2. Now we are trying to run the supply plan. We are not able to get output for DependentDemand.  Is it that we need to define the calculation of DependentDemand (ConsensusDemand*CRatio) or is it calculated through supply planning engine automatically?

Similarly please advice us for DepndentCustomer, Location and Production demands.

Regards

Atri Kundu

    Hi Atri,

    These KFs are computed by heuristics, calculations are part of the algorithm.

    Did you maintain the sourcing ratios?

    For example: Customer Sourcing Ratio is needed to get Dependent Customer Demand, to have your consensus propagated at the location level. And so on...

    You can check the attachments of this note, they are a very good start in understanding the planning operators.

      Hi Alok,

      I think you already raised another query for deletion of calculation definition. Please follow the steps mentioned there and then run the unconstrained plan once CDP is configured as suggested above.

      We will keep this thread open only for discussing heuristic issue in case it is still not resolved.

      Thanks,

    Hi Rohit,

    As there was some confusion with SP code, we are now working in a planning areaa where there is no SP code. So the definitions of the KFs and Planning levels are as per SAP2. We have a multi level supply chain to be configured. The example is shown below:

    We are able to generate the CDP and Statistical forecast at ProdCust. However we are not able to generate the Dependent Customer Demand even at WWDC level.

    Request your help.

    Regards

    Hi Rohit,

    as per your advice we have removed the PromotionsFCSTQty KF reference to PERPRODCUSTEVENT. Please note this is the same configuration as copied from SAP2.

    1. The unconstrained planning engine is running successfully and generating the dep demand, prod requirements calculations.

    2. The constrained planning engine is throwing error. The error says: Error: SCMPLAN | 129 | LEADTIMECOMPLETE_FINITE | 12/7/2015 12:56

    We have provided the prod lead time (1 month). Request your guidance in this regard.

    Thanks,

    Alok Joshi

    • Hello Atri,

      optimization runs in the foreground can be canceled, but I don't think that it is possible for runs in the background. In the worst case they can only be stopped via a HANA restart.

      Once an optimization run is finished, you select 'Show messages' to get some informations about the optimization run.
