A schema is used to define the structure of data. You can use a schema to parse the fetched data. If you want data transformation, then you need to use the required schemas both after the source and before the target end of your process flow activities. Perform the following steps to create a source schema activity:
1. On the Develop tab, in the Services group, click Schema, and then click the required source Format, e.g., Excel. The Manage Excel Schema screen displays.
2. Click the Create New link. The Create Excel Schema screen displays.
Enter the details and Save it.
