WARNING: App availability depends on referenced model existing

edited November 2022 in Modeling

Yesterday, I refreshed our Dev and Test models from Prod to start a new development cycle.  The Dev and Test models were actually brand new (only about a week old -- no in-model development, only App development) and didn't think I had any actual need to keep the previous versions since I was just looking to refresh data. 
I had been working on an App that pointed to the Dev and Test models that were deleted.  I wrongly assumed that I would be able to simply remap the app to the new versions of the models.  However, deleting of the model actually deleted the app.  Wow.  

A similar concept applies to archiving -- although this does not delete the App, it does hide it until the archived model is restored.  Only then can you point the app to a different model and re-archive.  

This concept needs WAY MORE ATTENTION.  I am hoping that Anaplan Support will be able to restore the workspace in question from 24 hours ago, as this would not harm anything and hopefully would restore the app.  I will update this post when I get more info... Wish me luck. 


Please see the following links for more information and upvote!!!  This really was a bad surprise that I didn't expect, based on the fact that an app can exist without any pages.

    Anaplan Support was able to help me restore the original models and the app.  Major kudos! 

    The window to restore a deleted model is 2 weeks, so if you end up needing this kind of assistance, do it QUICKLY.  😉

    So Sorry to hear about that. Yes, it is a pain and although I had already written an article about archival but never wrote anything about Deletion as that looked obvious - if archival of the model could do such things, deleting the model - all **** will break loose.

    Another issue that need attention is PUBLISH. When anything needs to  be published on UX, it is not environment specific, which it needs to be.

    Looks like there's something in the 'Targeted for November' release notes that may finally address the 'disappearing app when model archived' dealio.



    Has been a pain point of ours for some time as well.
