I believe aliases are poorly handled in FME. Please see my idea and upvote: https://community.safe.com/s/bridea/a0rDm000000zVtbIAE/improve-handling-of-aliases-for-datasets-that-support-them

Hello @ridleyj​, FGDB supports aliases, but I don't think the AGOL Writer is capable of this yet. FMEENGINE-74436 was filed to add support for aliases on feature services.

Did you reference the 'Advanced' section of the article to see how to add new field aliases using FME? iMark also explains it well here.

Regarding SDE, I wouldn't expect the FeatureWriter to behave any differently than the format writer when it comes to aliases. Are you able to write aliases with the format writer, but not the FeatureWriter? Would you be able to share a copy of your workspace and the version/build of FME being used? Happy to help, Kailin.

Hi @kailinatsafe​ 

Thanks for reaching out to help.

I did reference the advanced section (by my understanding of it!) and have the attached FMWT test, with sample data, for you to have a look at.

I am using

Version: FME(R) 2022.2.5.0 (20230329 - Build 22795 - WIN64)

OS Locale Name: en_NZ

OS Encoding: windows-1252

Process Encoding: UTF-8

FME API version: 4.0 20220615

Registration Key: 3-912-533-582

Registration: Licensed

Serial Number:

Customer Number:

Home Folder: C:\\Program Files\\FME\\

Operating System: Microsoft Windows 10 64-bit (Build 19041)

I didn't use or test the format writer

Hello @ridleyj​, take a look at the attached updated workspace. The aliases should be viewable in ArcGIS Pro now using the following steps:

1. Adding the appropriate writer (FGDB writer for example)
2. Removing all attributes with '_alias' from the writer feature type user attributes window

If the alias attributes are left in the user attributes section of the writer feature type, they will be written as literal attributes.

Also, as mentioned earlier FME doesn't support writing aliases to feature services as of yet. You will need to use the FGDB or SDE GDB writers to translate alias fields.

One potential idea (untested) could be to write aliases to FGDB and publish or push to AGOL, however I am unsure if the aliases would be maintained or dropped. Let me know if you're still having issues writing aliases. Happy to help, Kailin.

Oops @ridleyj​, forgot to attach the workspace! See attached.

Thanks @kailinatsafe​ , that answers my question - aliases on feature services not supported yet, but FMEENGINE-74436 is filed to add this support. The FGDB options work fine, thanks. Have noted your idea to publish to FGDB and push up/publish to AGOL feature service - this will likely be the approach until the alias option is embedded.

Cheers

Jason.

It seems that FME does not have the capability to write aliases to feature services, even on AGOL. The recommended solution is to use the FGDB or SDE GDB writers to convert alias fields. You can consider publishing to FGDB and then pushing it to AGOL as a temporary fix.
