Tables can be entered in and extracted from the function module / BAPI. Therefore, there are two types of behavior for tables: input type and output type.

To fill a table before BAPI execution set the Input Type to Static and click on the Edit link. You can fill the table’s row with static values or with variables.

To define a table for the use in the report set Output Type to Dataset. You can only set one table to this option. All other tables must be set to Skip.
