 Manually Adjusting the Demand History

Use

You can see and manually adjust the demand history that the system created during historical data capture.

Prerequisites

You have performed historical data capture so that InfoCube 9ADEMAND is filled.

Features

Display and Change

You can display and change the captured demand history on the SAP Easy Access screen by choosing Start of the navigation path Advanced Planning and Optimization Next navigation step Service Parts Planning (SPP) Next navigation step Environment Next navigation step Data Administration Next navigation step Adjust Demand History End of the navigation path . On this screen you enter a product and a time period.

For all location products that meet the selected criteria, you can then see the following information:

  • In the TPOP column, you can see whether a demand history exists for third-party order processing (TPOP).

  • In the VCL column, you can see whether a demand history for virtual child locations(VCL) exists.

  • For each location product, you can see the final history for both the demand and for the order items. The final history is the result of the following values:

    • History

    • Adjusted History

    • Scaled History

    • Adjusted Scaled History

      The system displays the history and the scaled history for each location product. You cannot change these key figures.

      You can fill the adjusted history and the adjusted scaled history with values. However, you can only ever fill one of these fields, not both at the same time. If you fill one of these fields and choose the pushbutton Apply , the system fills the other field accordingly. For more information about scaling, see Update Rules in Historical Data Capture in the Scaling section.

      Note Note

      If the change the values in this filed, the change only applies to the location product for which you change the values. The system does not aggregate or disaggregate the values along the BOD.

      End of the note.

      If you have manually adjusted the demand history, that is you have made entries in the Adjusted History or in the Adjusted Scaled History fields, the system takes the value of the adjusted scaled history as the final history. Otherwise the system takes the value of the scaled history as the final history.

      Note Note

      If you specify values for the demand, you must also specify values for the order items and vice versa. Otherwise you cannot save and the system generates an error message.

      End of the note.

  • For the demand of each location product, you can specify per period that this demand is promotion demand. To do so, enter the value 1 in the Promotion row. You thereby trigger the “SPP: Data Realignment for Promotion” planning service (SPP_PDEM_PROMOTION_RLG). When the system has successfully performed this planning service, it changes the value in the Promotion row to 2 . If the data realignment for promotion contained errors, it changes the value to 3 .

    In the Demand: Final Promotion and Item: Final Promotion key figures the system displays the demands and order items that are already assigned to the demand category PROMO_DEM .

    In the standard system, promotion demands are not forecast-relevant. If you mark a demand as a promotion demand, the forecasting service does not consider this demand. For more information, see Assignment of Demand Categories .

  • In the Period field you can select the periodicity that you want to see for the demand history. You can choose between the periodicity that you defined for the whole of Service Parts Planning (SPP) in Customizing or weeks.

    Note Note

    The system does not aggregate or disaggregate the demand history from one periodicity to the next, regardless of which periodicity you select.

    End of the note.

When you have made and saved changes to the demand history, the system sets the trigger SPP_RLG_DONE, which triggers the forecasting service. The system writes your changes to the DataStore object 9ADEMCRT. If you have made changes in the Promotion row, the system writes them to time series data management (TSDM).

Analyzing

You can also display the demand history as a query. It is therefore possible to see additional characteristics and key figures of the InfoCube 9ADEMAND that are not displayed on the Adjust Demand History screen, such as demand category.

We deliver the following example queries:

  • Demand History Month (9ADEMMUL_Q0001)

  • Demand History Week (9ADEMMUL_Q0002)

  • Demand History Period (9ADEMMUL_Q0003)

You can also define your own queries in the SAP APO Business Intelligence system (BI system) of SAP SCM that refer to your data in the InfoCube 9ADEMAND.

For more information about defining queries, see the SAP Library for SAP NetWeaver under Start of the navigation path AP NetWeaver Library Next navigation step SAP NetWeaver by Key Capability Next navigation step Business Intelligence Next navigation step BI Suite: Business Explorer Next navigation step Defining New Queries End of the navigation path .

You can assign names and (if you want) users to these queries in Customizing for Advanced Planning and Optimization under Start of the navigation path Supply Chain Planning Next navigation step Service Parts Planning (SPP) Next navigation step Forecasting Next navigation step Make General Settings for Demand History End of the navigation path . To do so, choose BW Query for Demand History in the navigation tree on the left.

You can see the queries we delivered and queries that you defined on the Adjust Demand History screen in the History field. When you select a query, your Web browser is opened and you see the selected query.
