Select Features with Different Attribute Value to Features in Different Layer?

[AlexanderWade]

Hello;

My organization recently upgraded to ArcGIS Pro, and we're currently using 2.7.  I have been tasked with integrating features from one layer (layer A) to a base layer (layer B). Each of these two polyline layers has a field called "ID". I need to integrate features from layer A that have ID values not present in layer B. Due to a variety of reasons, geometry isn't a deciding factor here; there are some features in layer A that have identical geometry to features in layer B but have different IDs. 

Is there any way to do something similar with Select by Attribute as is possible for Select by Location, IE "are identical" and then inverting the selection?

Thank you for your help.

You could use Add Join to join layer B (Join Table) to Layer A (input Table) (keep all target features).  Then, sort the attribute table by the Layer B ID field and select all the rows with empty values in the Layer B ID field (values in A that didn't match a value in B).

Now you have a selection of ID's that are in A, but not in B to copy/paste/append/whatever.
