Cross-company supervisor reporting relationships

Hi all. We currently have two companies defined in Lawson from a legacy implementation. We have not yet set up a supervisory structure in Lawson for Manager Self Service, but want to do so now.

We have many instances where people report across the companies (i.e. employee in company A reports to supervisor in company B) or where entire departments report across the organizational boundary. It appears Lawson will not allow a cross-company supervisor relationship. Has anyone else had a similar situation and did you come up with any resolution? Details would be appreciated!

Thanks,
Chris L
