Hello,
It's not a good idea to hardcode org units (or positions or users) into workflow steps. What if the users want to change that later? You would have to change the workflow and do a transport.
The usual way of doing this is to use a rule (AC......, created via PFAC). In there you will have the org unit. The org unit within the rule can be changed even in Production using OOCU_RESP.
