Fixed Resource Consumption in SAP IBP

[Former Member]

Is there any field to maintain Fixed resource consumption in SAP IBP S&OP.

By fixed resource consumption, i mean that whether we produce 1 unit or 100 units or 1000 units of the finished product, the resource consumption would be fixed to 1 hour only in each case.

The value for resource consumption is independent of the number of units of the finished product that is being produced.

Hi,

A production source resource is a resource that is used by a particular production source of supply. It models the capacity consumption of the production resource, that is, the amount of capacity consumed per unit of product produced.

The following attributes are used to model the capacity consumption of a production resource:

• CAPACONSUMPTION

  This is the capacity consumption of the specified resource per unit of measure of the product, where the capacity consumption is identical in all periods.

• CONSUMPTIONTS

  This specifies whether the capacity consumption is derived from the input key figure Capacity Consumption Rate of Production Resource (PCAPACONSUMPTION) instead of the master data attribute CAPACONSUMPTION. This attribute must be modeled as a checkbox. If the checkbox is selected in the master data object, the algorithm derives the capacity consumption from the corresponding input key figure. Therefore the capacity consumption can be different in each period.

It is not possible to have fixed resource consumption.

Hi Lingaiah,

Thank you for your answer. In such scenarios, how can we model fixed resource consumption in IBP S&OP?

Hi,

The workaround would be to create custom key figures and write the logic to copy the standard consumption rate with fixed consumption.

Standard key figures will update the consumption based on the production-consumption rate.

Custom key figures will populate the fixed resource consumption.

If you running time series infinite heuristics planning then it will work.

Best Regards,

Yes you can since 2311 in optimizer and more recently for heuristic. Check in online help this is explained in details. From an attribute in PSR you define the setup time by period, and after heuristic of Optimizer, you can read the keyfigure Fixed Production Capacity Usage (FIXEDPCAPAUSAGE) which has be considered in calculation, reducing the available capacity for production.
