Hello All, I have two tables like below. I want to know the difference (add, delete, unchanged) of the TractID field between these two tables. For instance, i want to have a output showing

unchanged: 1001, 1003

added: 1002, 1004, 1005

deleted: 1009

I didn't see the ChangeDetector transformer is able to compare two fields based on a string match. How to achieve this? I appreciate your help!

Table 1 (old):

IDTractID101001111003121009

Table 2 (new):

UniqueIDTractID1100121002,1003,100431005,1006

Hi @fmenewbie, the ChangeDetector can compare entire string match, but cannot detect partial matching. Split TractID of the table 2 into individual id values using the AttributeSplitter and explode the records on the resulting list using the ListExploder. You can then compare individual TractID using the ChangeDetector.
