Hi,
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?
Regards,
-T

Hi,
While uploading the transaction data , we need to make the system to look into the mapping table to find out the new value for old Customer value.
We have to write code for this in the start routine of transformation on transactional data.

HI,
I agree with Anil on that,it is the same reason for which few projects have key mapping repository in place,which holds the key field mapping information telling them that this Customer number means this in the Legacy system.
Well manual intervention is required as PR/PO which is active should be closed before such an activity.
Thanks,
Ravi
