Spatial Join and Select By Location - Getting Different result count

[RavindraSingh]

1. When I do Spatial join between two Polygon feature classes with below parameters, then i get 8 number of records as result:

• Target Features - Polygon feature class-1

• Join Features - Polygon feature class-2

• Output feature class-  .gdb path with file name

• Join Operation - 'Join one to one'

• Keep all target features - unchecked

• Match Option - 'Are Identical to'

• Search radius - blank

2. When I do Select By Location Operation with below parameters, then i get 10 number of records as result:

• Input Features - Polygon feature class-1
• Relationship -  'Are Identical to'
• selecting features - Polygon feature class-2
• Search radius - blank
• Selection Type - 'New Selection'
• Invert Spatial relationship - Unchecked

Ideally I should get same result, since Relationship I am using is  'Are Identical to'.

Please through some light here.

Looks like you have found a possible bug in Arcpro and how the different tools reconcile the relation Are Identical to. I would say you should edit your question and include the test data as a zip file for people to test to see if others can replicate the issue and discount if it is a hardware issue.
