Looks like I had this same question back in January of 2020: ListDatabaseSequences for Enterprise GDB and didn't get any takers then, but I'll toss it up again.
I have created a sequence in an enterprise geodatabase; at least I think I have. The arcpy.da.ListDatabseSequences() function is limited to file geodatabases. See ListDatabaseSequences—ArcGIS Pro | Documentation where it states :
This function is only supported for file geodatabases.
How do I verify that I have the sequence created as well as monitor where in the sequence values is? Is this functionality expected to be expanded to include egdbs anytime soon? (Or is it ideas time for me?)
