Alum Directory: improve the RE/NXT API so that changes to employment and education records made by alums in Almabase do not create duplicate records in NXT when synced. The issue is that we pre-populated data into our alum directory from RE/NXT which has 40 years of data for us. After recently launching Almabase to our alums, they enthusiastically updated their profile data with titles for the employer record as well as updated majors and minors etc for their educational records. However, when this data is synced back to NXT, a duplicate record is created in NXT. For example, if NXT already showed someone went to Stanford and the alum came into Almabase and updated that information to show they majored in Biology, when you sync that data from data inbox, NXT will show two Stanford records...one showing the major as biology. The wanted behavior is to append to the NXT record, not add it. We have been through this extensively with support and yes, our transformations and sync rules are correct. We are told this a limitation to the Sync API for both education and employment records.
