MáireDolan — Tue, 18 Feb 2020 11:31:33 GMT

When trying to use the "Make Route event layer" tool in ArcPro 2.4/2.5 I am presented with Error 000211 Cannot create route event source

When I revert to ArcMap it works!!

Any one else have this problem or can help in any way?

Did you try the suggested reinstall?

If it happening with all data you are trying to use and you looked at the suggestions on ensuring you have an objectid field etc as noted here

There are also issues on the Support Site

If none of those are applicable, you might want to file an issue with Tech Support.

The issue could be with that particular set of data, and that would have to be ruled out first

Thanks Dan,

I used the "Make Query Table" tool to regenerate an Object ID and that appears to have worked.

Thanks again

I was getting the 000211 Cannot create route event source error in ArcGIS Pro 2.9.3 and a coworker in ArcGIS 2.8.3.

Cause: table contained multiple begin milepost and end milepost attributes with the same alias (e.g. BMP with alias BMP, BMP_1 with alias BMP, and EMP with alias EMP, EMP_1 with alias EMP).

Note: I had coped SQL results into Excel (which had many columns named BMP and EMP), and then in Pro I copied the Excel table to my file geodatabase to create ObjectID values. The duplicate attributes were given _1 at the end, but the aliases remained the same as the original Excel column names.

Solution: Once I deleted the attributes with the same aliases, the Make Route Event Layer tool worked! (I tried renaming the aliases so that they would be unique, but Pro didn't recognize the changes in the tool).

Hello,

I realize this is a late response, but I had a similar issue recently in ArcGIS Pro 3.4 and 3.3.

I was able to resolve the same error after I realized the input for the 'Measure Field' parameter I was using was a text field, and the tool requires the parameter use a numeric field as indicated here -> https://pro.arcgis.com/en/pro-app/latest/tool-reference/linear-referencing/make-route-event-layer.ht....

After creating a new numeric field and populating it with the information from the original text field, the tool ran successfully and created the points along my route.

Hope this helps!
