Chatter FeedItem at mention

[yonto]

I am trying to create an SSIS package that will post to an Account's Chatter feed and @mention the account owner. I have been able to create the package and post something to an account's chatter feed. I have not been able to create the at mention. I have tried using derived columns to concatenate "@"+"[UsersName]" and "{@userID}" but neither have worked.

Any help would be appreciated.

It wasn't the way I intended to resolve the issue, but it works.
I created a custom object to load my accountID, userID, and chatter post text from my local database via SSIS.
From there I created an APEX trigger on the custom object using the ConnectApi that references the fields in the custom object to build out the acutal chatter posts.

Please confirm that the issue is solved, and no investigation from our side is required.

My issue has been resolved, though I did not find a way to do it through the devart tool.
