# Define variables
input_features = r"C:\data\Edit_Sample.gdb\Roads"
maximum_removal_length = "50 Meters"

# Execute Remove Self Intersections
arcpy.RemoveSelfIntersections_production(input_features, maximum_removal_length, "REMOVE_SNAPPED", "REPAIR_ONLY", "#")

# Check in Production Mapping license
arcpy.CheckInExtension("Foundation")
