When you need to edit a large portion of a transformation, you do not need to change every value in the Developer tool. Instead, you can copy the transformation ports to Excel, change all the values simultaneously using Auto Fill, and then
Paste (Replace)
the transformation ports back into the Developer tool.
In the mapping editor of the Developer tool, select the transformation that you want to copy ports from.
To copy the original transformation from the Developer tool, right-click within Ports and click
Select All.
Copy the ports to an Excel spreadsheet.
Make changes within the Excel spreadsheet. If you are changing large portions of metadata, you can use the Auto Fill feature in Excel. This allows you to fill in data based on adjacent cells by dragging the fill handle. See
Example: Editing a Transformation in Excel for more information.
Copy the metadata from Excel.
To update the transformation with the changes, right-click within Ports and click
