To support merging of an entity, three properties have been added to the entity data model and corresponding columns are also added to the respective entity database table.

• MergeStatus (Possible values: Active/Inactive)
• MergedTo
• Snapshot (PegaPS-Data-Snapshot)

In the following example PERSONS-5 is selected as the master, and PERSONS-1 as the duplicate

Entities before merge

Entity ID	Merge Status	Merge To
PERSONS-5 (Master)	--	--
PERSONS-1 (Duplicate)	--	--

Entities after merge

Entity ID	Merge Status	Merge To
PERSONS-5 (Master)	Active	--
PERSONS-1 (Duplicate)	Inactive	PERSONS-5

As PERSONS-5 is master it has the status as Active and PERSONS-1 would have the status as Inactive and the MergedTo of the master which is PERSONS-5.

All merged data is conserved to support unmerge functionality which will be made available in future releases. The master entity instance maintains the Snapshot (PegaPS-Data-Snapshot) embedded page; an image of master instance data before the merge
