I have two tables for blocks data, each block in these tables is identified by its block ID, and I want to find the unmatched blocks between these tables.
In ArcMap, I joined the two tables based on the "Block ID" fields, after validating the join, 822 out of 1496 blocks were matched.
However, I tried to do the same thing using FME, I created a workbench that reads from these two tables, and applied a feature merger on them to compare the "Block ID". However, the results were different; there was 1011 matched "merged" blocks!
I could not figure out why FME results are different from ArcGIS ones. What might be the issue here?
