I am using the Contact table and a custom table for Reports in a model-driven app.
I have created the lookup one-to-many relationship (contact to reports). So for newly created contacts and reports things are working.
I have existing data on two Excel tables that I need to import and retain the relationship between the two tables.
On the Contact Excel table, for each contact record there is a whole number ContactID.
On the Reports Excel table, for each report record there is a whole number ReportID. I have a ContactID column on the Report Excel table that associates the contact with the report record.
I know I am missing something fundamental here, but I just can't see how to import and retain this relationship on these thousands of existing records. Can someone please help? Thank you.
