I am trying to migrate data into two different entities on a model driven app.
These entities have a relationship together. Entity "A" has a list of product IDs and entity "B" IS a list of product IDs. However, the data set for "A" only has about 1000 records, all of which are in the data set for "B", which has about 2000 records. The Product IDs in data set "B" have all of data set "As" product IDs intermingled in there. Is there a way to programmatically use the import wizard to pair up the existing product IDs in entity "A" with entity "B" so that i can have a link between the two?
