Let's say you've set them up in your DEV system and now you're expecing to just transport them. Well, as with all things SAP, it's never quite that easy.
Create a new workbench transport request in SE01, SE09 or SE10 (doesn’t matter which).
Then open the request at the request level by double clicking it.
Switch to change mode by clicking the pencil button:
Now manually type in the program Id, object type and object names as follows:
R3TR TABU USGRP
R3TR TABU USGRPT
Click Yes at the prompt:
On each item, click the Function button (key symbol):
Enter * in the Table Keys field:
Save the request again.
Release the transport and import into the next system.
This is a farily generic process that can b used to transport any table values.
NOTE: You should be aware that the "*" in the table key, means all items specific to the current client.
