what is the goal of this scenario?
Is it made for a data migration and hence just a one-time event, or do you want to update the info record in the satellite system when you change it in the main system?
I mean if you remove the info record number then SAP will automatically create a new info record with a new number, but how can ensure that an update will hit this new info record if you do not have a mapping between the info record numbers in the old and new system?
