How to Create and Use Characteristic Value Variables with a Replacement Path from a Query in SAP BW/4HANA Queries with Examples

SAP BW/4HANA is a data warehouse solution that allows you to analyze and report on large volumes of data from various sources. One of the features of SAP BW/4HANA is the ability to create and use variables in queries. Variables are placeholders that can be replaced by values at query runtime, depending on the user input or system settings. Variables can help you to make your queries more flexible, dynamic and user-friendly.

In this blog post, we will explain how to create and use characteristic value variables with a replacement path from a query in SAP BW/4HANA queries. Characteristic value variables with a replacement path are variables that are replaced by the results of another query. The results can be determined from the key, the external attribute of the key, the description, or the attribute value of the reference characteristic. You can also define an offset start and offset length for the replacement.

We will also show you some examples of how to create and use characteristic value variables with a replacement path from a query in different scenarios, such as filtering by customer group, calculating the sales margin or displaying the product category.

Creating Characteristic Value Variables with a Replacement Path from a Query in SAP BW/4HANA Queries

To create and use characteristic value variables with a replacement path from a query in SAP BW/4HANA queries, you need to use the Query Designer tool. The Query Designer allows you to drag and drop InfoObjects or reusable query elements from the InfoProvider screen to the query rows and columns. You can also edit the properties of the variables using the Properties pane.

Here are the steps to create and use characteristic value variables with a replacement path from a query in SAP BW/4HANA queries:

1. Open the Query Designer and select the InfoProvider that you want to use for your query.
2. Click on Variables on the toolbar to open the Variables screen.
3. Click on Create Variable to create a new variable, or select an existing variable and click on Edit Variable to modify it.
4. In the Create Variable or Edit Variable dialog box, enter a name and a description for the variable.
5. Select Characteristic Value as the variable type from the drop-down list.
6. Select the reference characteristic from the drop-down list. The reference characteristic determines which values can be assigned to the variable at runtime.
7. Select Replacement Path as the processing type from the drop-down list.
8. In the Replacement Path tab page, select Query as the replace variable with option.
9. Choose the query whose result you want to use as the variable using the input help dialog . For more information on using the input help dialog, see Restricting Characteristics.
10. Choose where the value of the variable will be determined from: Key, External Attribute of Key, Description or Attribute Value. If you choose Attribute Value, select the attribute you want from the drop-down list.
11. Optionally, enter an offset start and offset length for the replacement.
12. Click on OK to save the variable.

Using Characteristic Value Variables with a Replacement Path from a Query in SAP BW/4HANA Queries

After creating a characteristic value variable with a replacement path from a query, you can use it in your query by dragging and dropping it from the Variables screen to the query rows or columns. You can also use it as a filter or a formula element.

Here are some examples of how to use characteristic value variables with a replacement path from a query in SAP BW/4HANA queries:

• To filter by customer group using a characteristic value variable called CUST_GROUP_VAR that is replaced by the result of another query called CUST_GROUP_QUERY, drag and drop CUST_GROUP_VAR from the Variables screen to the Filters screen. In CUST_GROUP_QUERY, you have defined Customer Group as an output column and restricted it by some criteria. For example, if you want to filter your query by customer group using CUST_GROUP_VAR that is replaced by CUST_GROUP_QUERY, you can drag and drop CUST_GROUP_VAR to
  Filters screen and select Single Value as selection type and Equal To as comparison operator.
• To use a characteristic value variable in a calculated key figure formula, drag and drop
  variable from Variables screen to Calculated Key Figures screen. In Properties pane,
  enter a formula for calculated key figure and include variable name enclosed by & signs
  (for example, &VAR_NAME&). For example, if you want to calculate the sales margin using a characteristic value variable called SALES_MARGIN_VAR that is replaced by the result of another query called SALES_MARGIN_QUERY, you can drag and drop SALES_MARGIN_VAR to the Calculated Key Figures screen and enter a formula like this:

In SALES_MARGIN_QUERY, you have defined Sales Margin as an output column and calculated it as a percentage of sales and cost.

• To use a characteristic value variable in a selection or a formula of a structural component, drag and drop the variable from the Variables screen to the Selections or Formulas screen. In the Properties pane, enter a selection or a formula for the structural component and include the variable name enclosed by & signs (for example, &VAR_NAME&). For example, if you want to create a selection that shows only products with a certain product category using a characteristic value variable called PROD_CAT_VAR that is replaced by the result of another query called PROD_CAT_QUERY, you can drag and drop PROD_CAT_VAR to the Selections screen and enter a selection like this:

In PROD_CAT_QUERY, you have defined Product Category as an output column and restricted it by some criteria.

Conclusion

In this blog post, we have shown you how to create and use characteristic value variables with a replacement path from a query in SAP BW/4HANA queries with examples. By using characteristic value variables with a replacement path, you can make your queries more flexible, dynamic and user-friendly. You can also leverage the results of other queries as variables in your queries.
