Press the Configure button which will display a popup shown in the picture.
Define mass execution types that will be performed during the extraction process execution. Use the provided toolbar to specify the configuration. Following operations are available:
Add data split -Adds new data split to advanced mass execution configuration.
Remove data split - Removes selected data split from advanced mass execution configuration together with parameters already defined for the selected data split.
Define parameters - Allows you to define and change parameters for the selected data split.
When data split types are added to the mass execution configuration, you need to define parameters for each split you wish to include. You can do so by selecting the data split type and pressing the Define parameters button from the toolbar. You can find more information about defining parameters for particular split types in the section Configuring advanced data split types.
After all parameters have been defined, you need to confirm the parameter selection by pressing the Confirm button. In case of pressing the button Cancel, all changes you made will be discarded.
We recommend you save this configuration as a standard SAP variant so you will be able to access the definitions later without the need to configure them again.
...
As you can see, there are two data split types defined within the configuration. The first one splits the data into portions based on the actual number of records in the source object and the second one splits the data based on the time characteristic. To learn more about split types, follow the page /wiki/spaces/GLUE/pages/1517846614 chapter Mass Execution for basic types and section Configuring advanced data split types for advanced data split types.
...
As mentioned in previous sections, you can define multiple data split types within an advanced configuration. The basic data split types definition is equal to the definition using basic mass execution capabilities with a similar user interface. Therefore, we will not mention them here and you can read about them on the page /wiki/spaces/GLUE/pages/1517846614in the chapter Mass Execution.
Composite data split
Composite data split represents a general wrapper that binds various splits together and is always configured when advanced data split type is selected. Therefore, it is not present as a split type within the Advanced Mass Execution popup and won’t be discussed further. You can find the details on the page /wiki/spaces/GLUE/pages/1517846614in the chapter Mass Execution.
