Feature request: Allow editing of Workbench data set mappings

Wed, 03/10/2010 - 16:22 — mcwinans

If I import a data set, realize I've made a mistake in the mappings, and want to fix the mapping and try again, it would be nice not to have to start over right from the beginning. If a data set has a large number of columns, the process of defining these mappings can be very time consuming. Being able to modify and then reuse an existing mapping for the new data set would be faster and less error-prone.

This is already possible

1. Open the WorkBench
2. Make sure the dataset you want to change is not opened
3. Right click on the dataset you want to change in the menu on the left
4. Choose "Edit data set mapping"
5. You can now edit the data mapping.

Reusing existing mappings:
- If your dataset has column headers that match perfectly with one of your existing mappings, Specify will detect this.
- If you choose "New data set", you can decide which mapping to use. You could then copy and paste data in this new dataset, but this is somewhat cumbersome.
