Releasing
Customizing Requests: Dialog Step Dropped 
Scope of Functions
The dialog step Release Customizing Request no longer appears when you release Customizing requests.
This dialog box let you append the Customizing request to a Workbench request, instead of releasing it directly.
This function made it possible to link two requests of different types and make sure that their contents were imported together. This is important if there are logical or technical dependencies between the requests.
As of Release 4.6C, this dialog step no longer appears when you release Customizing requests.
Instead, you can link the requests before you release the Customizing request by choosing Utilities -> Reorganize -> Customizing request -> Append to Workbench request.
As long as you do not release the Customizing request, you can split up the requests again.
