We would like to be able to be able to properly replace the current primary business (PB) on an individual using an import. Currently, the PB marker is simply moved to the new record. We'd like to add an end date to the existing PB.

The OoB 'add organisation relationship' form uses a combobox to select a relationship to replace. This is not possible to do via an import, but behind that form, CRM does end date the old relationship.

This could work with a boolean field in the file mapping and staging areas that triggers some code to end date the previous PB during processing. It may be necessary to load the GUID of the old PB as an initial step so that it's not lost when the new PB is added.
