Your organization receives customer data from different departments frequently. The departments might periodically change the source schema to include additional columns for departmental analysis. Your organization needs to incorporate all the updated data in a short span of time.
To refresh the source schema dynamically and fetch the changes from the data source, you create a dynamic mapping. Add all the dynamic ports to the target to override the metadata of the existing ports.
