Before you use Central Office for the first time, it is very important that you understand the concept of Local IDs vs. Global IDs.
A Local ID is a unique identifier assigned to every record created in Millennium.
A Global ID is a unique identifier assigned to every record created in Central Office.
When you upload Millennium data to Central Office, Central Office assigns a unique Global ID to every record to help identify the record across all locations. When you copy a record to multiple locations using Central Office, the record will have the same Global ID at each location.
If you create a record independently at two separate locations, the records will have different Local and Global IDs. To maintain the integrity of your data, reduce errors, and make reports more accurate, you need to merge duplicate records to use the same Global ID.
Example: If you add a client profile at Location A and add a duplicate profile for the same client at Location B, the profiles will have different Local and Global IDs. To correct this situation, you need to merge the two profiles into a single profile that you can use when the client visits any location.
More Info: Refer to the Maintenance topic for instructions on how to use the Data Editor to merge duplicate records.
