What is a Time-series Analysis?

Choose the correct answer.

If you are not sure about the nature of time-series data in your planning area, you can set the system to analyze the values of a selected input key figure based on predefined rules, and save the identified properties in the background. This process is called time-series analysis.

If you are sure about the nature of data, you do not need to analyze the values of a selected input key figure. This process is time-series analysis.

Which two processes use a forecast error calculation with different approaches?

Choose the correct answer.

Inventory optimization and demand planning.

Cost optimization and profit planning

Supply optimization and order planning

What is forecast error variability in this context?

Choose the correct answer.

Variability is a number which is not necessary within the supply chain.

Variability is the quality of being variable in the time. In this context, the forecast error variability is the measure of the forecast error fluctuations over time.

What does SAP IBP for inventory calculate?

Choose the correct answer.

Provide master data for inventory calculations as lead time, lead time variance, and lot sizes.

Calculate inventory parameters as: recommended safety stock, target inventory position, reorder point, and target service level.

Delivers forecast and the forecast coefficient of variance.

What is demand variability in this context?

Choose the correct answer.

This is the measure of demand fluctuations over time.

A unit of measure to convert prices, currencies and international unit of measures.

Neither of these options.

Which three groups describe the demand characterization?

Choose the correct answer.

Unrealistic, non-existent, and inconsistent demand.

Imaginary, obsolete, and impossible demand.

Frequent demand, intermittent demand, and seasonal demand.

Inventory planners take care of the following processes:

Choose the correct answer.

Designing the inventory planning processes, characterizing the inventory optimization technology, controlling the results of the process in terms of inventory, considering working capital implications and ensuring supply chain reliability.

Calculate forecast and supply quantities.

How can we handle historical data before we optimize with SAP IBP for inventory?

Choose the correct answer.

Via ad hoc formulas in Excel.

Through missing data recognition, via outlier detection, and through forecast bias identification.

We do not need to handle the data because the data is always right.

What is an ABC/XYZ Analysis?

Choose the correct answer.

ABC/XZY segmentation is the prioritization of planning objects based on their relative importance.

ABC/XYZ segmentation is the classification of planning objects based on their demand volatility.

ABC/XYZ segmentation is the method of grouping planning objects based on the values of a selected key figure.

10.

Which of the following processes can be established to determine supply lead times to the algorithms of IBP for Inventory?

Choose the correct answer.

Determination based on historical data using algorithms

Run inventory optimization algorithms without consideration of lead times.
