To open a mapping, drag it from the Navigator into the Mapping Designer workspace. If you have a mapping in the same folder already open, the Designer prompts you to close it before continuing. Click OK to close the current mapping and open the other one.
You can open one mapping at a time in a folder. If you open more than one folder at a time, you can open a mapping in each folder.
To open a mapping, you can also right-click a mapping in the Navigator and choose Open.
