The documentation here is incorrect. The example SetupStoreByTable function in the ArcPY script at the bottom reads: arcpy.SetupStoreByTable_ba(Input, Locator, FldCol, StoreName, "USE_EXISTING", StoreId, OutFC)
It should read according to the documentation DIRECTLY ABOVE it and python reflection: arcpy.SetupStoreByTable_ba(Input, Locator, FldCol, StoreName, StoreId, OutFC, "USE_EXISTING")
If you run it the way it is an exception is thrown with the message "Cannot set input into parameter WayToSpecifyStoreIDField."Tyler
