I am trying to use the ArcPy code below with ArcGIS Pro 3.0.0 and a File Geodatabase to:
- Create events for my LRS Network on its first run
- Remove my LRS events and then delete its event feature class, before recreating events for my LRS Network on its second and subsequent runs
import arcpy
gdb = r"C:\temp\test.gdb"
fdName = "testLRS"
fd = r"{0}\{1}".format(gdb,fdName)
lrsNetworkName = "TestLRSNetworkR"
lrsNetwork = r"{0}\{1}".format(fd,lrsNetworkName)
eventFCname = "TestEventFC"
eventFC = r"{0}\{1}".format(fd,eventFCname)
if arcpy.Exists(eventFC):
arcpy.AddMessage("Removing LRS Event {0} and deleting {1}".format(eventFCname,eventFC))
arcpy.locref.RemoveLRSEntity(gdb,"EVENT",eventFCname)
arcpy.management.Delete(eventFC)
arcpy.AddMessage("Creating LRS Event {0} and its feature class".format(eventFCname))
arcpy.locref.CreateLRSEvent(lrsNetwork,eventFCname,"LINE", "EventId",
"FromRouteId", "FromDate", "ToDate", "LocError", "FromMeasure", "ToMeasure",
"NO_SPANS_ROUTES", "ToRouteId", "STORE_ROUTE_NAME", "RouteName", "ToRouteName")
I run the code by adding it to a toolbox as a Python Script tool with no parameters.
When I run it once the new LRS events are created as expected.
When I re-run it I get an error:
ERROR 003207: ...\testLRS\TestEventFC cannot be deleted because it participates in a Location Referencing dataset
This is unexpected because I have no problem using the Catalog pane to right-click on ..\testLRS\TestEventFC and Delete it. I am also able to delete it by loading the Delete tool into the Geoprocessing pane - it is just trying to do it from Python that causes the error.
I have tried using a Python sleep function for 30 seconds between RemoveLRSEntity and Delete just in case it needs a little time to finish the RemoveLRSEntity but that makes no difference.
Is there any way that I can use Python code to check for LRS events, remove them as an LRS entity if they exist, and then delete the underlying event feature class?
