Hello,
In Logistic store view of article master, navigate to other Logistic data and maintain Unit of Issue. Apart from this, you need to maintain the dynamic rounding profile and assign in logistic data.
These two can help you to generate STO from single DC in different unit of measure as per store's unit of issue.
In the current project, we have implemented this and is working fine.
Let me know if you need any other help.
Regards,
Amit
