Hi,
For instance : Purchasing departmant have a manager and a lot of expert but manager want to control some experts.
I am not sure-how your business allow you set release strategy for a instance with for single department.Release strategy/strategies is/are designed based on business requirement on business process control for purchasing documents.
In an organization,Purchase order creators are many-may be more than hundreds and how many release strategies you will design!
If business force you to create release strategies - you can go for enhancement passing your wanted field value by having having release characteristic CEKKO-USRC1 or CEKKO-USRC2.
Check and cross check with business - design approval procedure based on following release characteristics
CEKKO-BSART
CEKKO-BSTYP
CEKKO-BSART
CEKKO-GNETW
CEKKO-GNETW
