Enable Undo on custom toolbox not working on feature service layers?

[vincentng_silvacom]

I've been trying out the new feature to enable the Undo toggle on custom tools in toolboxes mentioned in the blog post https://www.esri.com/arcgis-blog/products/arcgis-pro/analytics/build-custom-tools-in-arcgispro

It definitely works as intended if I test it against a feature that lives in a file geodatabase.

However, if I use it to edit a layer that comes from a feature service (e.g. something from a parcel fabric service), it isn't possible for it to Undo.  Even if I use GP tools that can undo in this branch version scenario within the script tool, the undo doesn't work.  Is there any way to make this work?

Hi @vincentng_silvacom, the issues you are facing with Enable Undo could be because you are using the default version of the branch versioned feature services. Otherwise, I believe you may be encountering a bug, which can be logged with technical support: https://support.esri.com/en-us/contact

Hi Margaret,

I can confirm that I wasn't on the default version, as the environment I was working in has that locked down. I'll let one of our authorized callers make a support case for this. Thanks!
