1. Workbench Request
Contains cross-client objects.
These are usually repository objects that affect the entire system, not just one client.
Examples:
ABAP programs, Function Modules, Classes
Dictionary objects (Tables, Views, Data Elements, Domains)
Screens, Module Pool programs, etc.
Once transported, the change is available in all clients of the target system.
👉 Think of Workbench = Development objects (cross-client).
2. Customizing Request
Contains client-specific settings made in SPRO (IMG) customizing.
These are configuration settings that only affect the client in which they were made.
Examples:
Company Code settings
Plant settings
Number ranges
FI, MM, SD configuration changes in SPRO
Once transported, the customizing change is available only in the target client, not all clients.
👉 Think of Customizing = Configuration settings (client-dependent).
3. TOC (Transport of Copies)
A special type of transport request.
Used when you want to test changes in Quality (or another system) without releasing the main request.
Contents of the original request are copied into a TOC and transported.
The original request remains modifiable (still open).
Once everything is tested successfully, the original transport request can be released to move changes to Production.
👉 Think of TOC = A “temporary copy” of your transport for testing.
