Hi Frode,
When upgrading from using rank 1 to 'main contact', the upgrade will fill the 'main contact' field with the persons having rank 1 today (or next if rank 1 is missing). Former employees will be skipped, getting next person with lowest rank.
For those already using this field in Service, we will keep current data in this field, and not replace it with data from rank 1.
Would be nice if you could send us some detailed information. Could it be that the 'main contact', former 'primary contact' in Service was in use and had data in the field before upgrade?
Best regards,
Trude
