To shorten the time it takes to maintain output types, procedures, conditions, etc. add NACE to your shortcuts. You can do it all from one transaction without wading through the IMG for each different functional area.
When you run NACE, you are presented with a list of applications, like E1 for inbound delivery, EF for purchase order, V2 for shipping and V3 for billing. Most of these applications are related to MM or SD, so you won't find output control for payroll documents, for example.
Select the application you need to configure by clicking on the box in front of it. You can then choose among the options available to create or change condition records, procedures, output types, and access sequences for the selected application.
For example, you can create a new output type, assign a program and/or form to that output type, insert it into an existing Procedure (or create a new Procedure), and maintain the condition records that will cause that output type to run, all from NACE.
You can do the same work in "Customizing," but each application is in a different area of the IMG, so you have to hunt for them. With NACE, they are all in the same place.
