Procedure documentationForecast & Simulation

 

Using the Forecast & Simulation Cockpit, you can experiment with different parameters to simulate the impact of various data reduction measures on the database size of a system and the expected cost savings over a defined period.

You can use the basic mode to generate a general overview of the trend. Alternatively, you can use the expert mode to enter more detailed information and configure the forecast to more accurately simulate specific data reduction measures across multiple systems.

Prerequisites

  • You have completed the Managed System Preparation step in the Data Volume Management scenario of SAP Solution Manager Configuration for all systems you want to include in the analysis.

  • You have completed the Activate DVM Extractors step in the DVM scenario of SAP Solution Manager Configuration to activate the extractors for the Business Warehouse (BW).

  • You have the correct authorizations for the connected Business Warehouse (BW) system. You need this authorization to load data from the BW.

Procedure

Basic Mode
  1. Under Data Source, select whether you want to enter the data used as the basis for the forecast manually or whether you want to use current system data from a selected system:

    • If you select manual data entry, under Size and Growth, enter the corresponding values. The mandatory parameters are marked with an asterisk (*).

    • To use current system data, select a system from the table. Under Size and Growth, choose Get Size and Growth to automatically input data from the selected system.

  2. Under Additional Data, enter the corresponding values that reflect your cost/GB and critical size.

  3. In the Data Reduction % (Archiving) area, enter percentage values for both a moderate and aggressive reduction approach. The default values are 25% and 50%.

  4. In the Forecast area, select whether you want to forecast the Growth Trend or the potential Cost Savings.

  5. Select a forecast period.

  6. Choose Simulate Forecast.

For a growth trend forecast, the system generates a graph comparing when your data volume will reach the critical size depending on whether you take a moderate approach, aggressive approach, or take no action at all.

For a cost savings forecast, the graph compares how much money you can save over the specified period depending on whether you take a moderate or aggressive approach.

Expert Mode
  1. Choose Switch to Expert Mode.

  2. You can either create a new project or select an existing one.

  3. In Step 1: Choose Systems, select the systems that you want to compare in the forecast simulation.

  4. Choose Apply.

  5. In Step 2. Enter Details, under Generic Data Applicable for All Systems, enter the corresponding values that reflect your cost/GB and critical size.

  6. Select a system and then choose Get Data to automatically input data from the selected system. Alternatively, you can enter the values for Size, Growth, and Anticipated Growth Factor manually. Repeat this step for each system you want to analyze.

  7. Under Technical Savings you can enter percentage values for various technical saving measures.

  8. Specify a realization date for each measure; that is, the date by which you want to achieve this savings percentage.

  9. In the Data Reduction % (Archiving) area, enter percentage values for both a moderate and aggressive reduction approach. The default values are 25% and 50%. In addition, specify a realization date for each approach.

  10. In the Expected Data Growth table, you can specify the expected growth of application areas, document types, and tables in the system due to planned projects. Select Application Area, Document Type, or Tables and choose Get Details. Enter the expected additional growth and the realization date for each object. Alternatively, choose Add Row and enter the data manually.

  11. Under Step 3: Forecast, select whether you want to forecast the Growth Trend, the potential Cost Savings. Alternatively, to compare the impact of measures on the selected systems, select System Related.

  12. Select a forecast period.

  13. You have the following options:

    • To simulate the impact of all measures, select Impact of Combined Measures and one or more reduction approaches.

    • To simulate the impact of each measure individually, select All Measures Individually for the Selected Items . Select whether to simulate a reorganization and other measures, as well as whether to simulate either a database compression or HANA migration.

  14. Choose Simulate Forecast.

A graph and table display the forecast according to the criteria you specified.
