-
In the Preparation path field, enter the path to the
customers_leads preparation you want to apply on the
.csv file.
Your preparation must have the same path on your Talend Data Preparation development environment and production environment.
- In the Preparation version field, type Current state between double quotes, in order to use the current version of the preparation.
-
Click Fetch Schema to
retrieve the schema of the preparation.
The output schema of the tDataprepRun component now reflects the changes made with each preparation step. The schema takes into account columns that were added or removed for example. By default, the output schema will use the
Stringtype for all the columns, in order not to overwrite any formatting operations performed on dates or numeric values during the preparation.
