Table Compare

Table Compare (found under DataSync > Tools) allows you to compare a table on your ServiceNow instance with the table in another database or another ServiceNow instance. By comparing two tables, you can see each table's record count as well as a list of record discrepancies by sys_id between the two tables that you are comparing (i.e. which records exist in one table and not in the other). 

 NOTE: Most recent update of the record is checked for. If the most recent record is not found, the record will be res-hared
