Quantity Management

In engineering and construction businesses, high-level quantities are usually available during the bid or pre-contract phase. Hence, to achieve the scope of work, the focus is primarily on planning the necessary resources by using productivity to determine corresponding quantities for each resource. For example, if a paving machine can lay 2 kms of road each day, you will need the machine for 50 days to construct 100 kms of road.

The planning workbook for quantity-based planning allows you to plan for one structure element at a time and to link the output quantities to a statistical key figure. On transfer of plan data to the SAP ERP back-end system, the output quantities are stored against the corresponding SKFs.

Prerequisites

In Create Statistical Key Figure (transaction KK01), you have defined statistical key figures and assigned them to a controlling area.
To import statistical key figures into the BW master data, you have scheduled a background job using the report Create Master Data for Statistical Key Figures (/CPD/PFP_CREATE_SKF_MSTR_DATA).

Caution
When you update BW master data using this report, the underlying APIs do not process any numeric data that are not of the length defined at the level of the characteristic. Therefore, the system automatically adjusts the length to suit the defined length. For example, the characteristic /CPD/STKEYFIG specifies that the internal length of InfoObjects in BW is 6. This means that when a value such as 1111 is passed from ERP, the system prefixes 00 to 1111 (finally represented as 001111). This is done so that the processing is accepted by the system, because the underlying APIs expect a 6-digit numeric value. Therefore, what is very critical, in this scenario, is to note that the values 01111 or 001111 are treated as duplicate entries by the system.

End of the caution.
You have made the necessary settings in Customizing under SAP Commercial Project Management Project Cost and Revenue Planning .

Features

Integration with SKF

You can link output quantities to statistical key figures, in the unit of measure assigned to the SKF. During planning, you must select a statistical key figure that is assigned to the controlling area of your master project.

Separate Planning Views

The new workbooks developed for quantity-based planning consist of two views – the output view and the input view.

In the output view, you plan output quantities, which the system uses to calculate required input quantities based on the productivity of each planned resource. Other values such as planned output unit price, planned output cost, and planned output productivity are displayed as a result of calculation or valuation.

In the input view, you plan the resources, the input productivity, and the cost per resource. When you use the Calculate function, the system proposes input quantities based on the output quantity and input productivity.

Output Quantity

This is usually a value in a bill of quantity and defines the scope of work for a structure element. When you plan for an output quantity in a structure element, you must also assign the output quantity to a statistical key figure.

Planned output quantities are transferred to the statistical key figure when you initiate transfer of planned data to the back-end ERP system. To know about the transfer methods used to transfer output quantities to SKFs, see Transfer of Planned Data.

Input Productivity

Productivity is a measurement of rate of output per unit of time or effort, usually measured in labor hours. For example, cubic yards/cubic meters of concrete placed per labor hour or some other standard measure.

Output Productivity

This value is calculated and indicates the average productivity of resources belonging to activity types. The system calculates this by dividing the total planned quantity of such resources or resource types by the total output quantity.
