Using Custom Transformers

Especially considering the increasing number of very large transformations, using custom transformers can simplify many workspaces. A large workspace that is decomposed into smaller pieces will be easier to manage.

Including a custom transformer in your workspace

Choose the custom transformer from the Transformer Gallery.

Opening a custom transformer

If you exported the custom transformer you can also open it just like you would a regular workspace.

1. Choose File > Open and browse to your FME > Transformers folder.

Editing custom transformer definitions

You can edit an embedded custom transformer (one that you previously exported) by clicking its tab at the top of the workspace window and editing the contents, or right-clicking on the custom transformer and choosing Edit from the command menu.

The changes are automatically applied within the main workspace, wherever the custom transformer is used.

NOTE: If you delete a custom transformer from the main workspace, you will have to recreate it. As long as its original tab is still open in the workspace, you can use its contents to create a new custom transformer. Choose Insert Custom Transformer from the main workspace, then copy and paste the contents of the original tab to the new tab. You can then close the original tab.
