We've made the data connection parameters from the data pool where you're working with objects and events, available in the SQL editor for your transformations for objects and events. You can use them to access multiple source systems from the same transformation, in addition to the main data source that you're working with.

Use the Data connections tab in the Parameters panel to view and add the available data connection parameters in your statements. You can put them in custom transformations, and also in full and partial overwrites that you create for Celonis transformations. Wherever you don't use a data connection parameter in an SQL query, we'll run the query on the default data source that you've selected in the Data sources panel for the transformation, like before. Wherever you add a data connection parameter, we'll run the query on the data in that schema. For the instructions to create custom transformations and overwrites, see Creating custom transformations.
