In IronPython API, DataSourceOperations class has the ReplaceDataFlow() method which allows Data Table replacement without affecting downstream Data Transformation steps, similar to manually replacing in Data Canvas (i.e., click on table > Replace data source).
This method is not available for DataTableDataSourceOperations class; it has the ReplaceData() method, which removes all downstream Data Transformation steps.
Having to re-add the deleted Data Transformation steps is tedious.
I would highly appreciate the function.
For me, I have a table which consists of the merge of two other tables and one DataSource. I would like to replace one Table which a DataSource. But as a matter of fact, I looks like it is not possible. And I do not want to use the ReplaceData() method, since it will remove all merges and transformations as mentioned above.
Hi Ivan, thank you for contributing. I have a little problem understanding the idea. Do you want an API for changing data table in DataTableDataSourceOperation? And that such call would not affect any downstream transformation steps?
