Suppose we have three legacy systems holding customer master data. We fetch the data from these three systems into MDM and consolidate the records. Let's say there were three customer master records:
CUST123, John James, 123 Elm Street
CT00123, James, John, 123 Elm St.
0000123, John James, 123 Elm Street.
We merge them in MDM and create one record
NEWCUST123, James, John, 123 Elm Street
Question is: How the transactional data from the three legacy system will be mapped to this new customer master record? How the purchase orders will know that CUST123 is now NEWCUST123 ? When this mapping happens in a project and who does that?
