Annotations/notifications on virtual hierarchies not fully functional

[Wei Wang]

We have encountered some issues related to inserting Annotations to tables that utilize virtual hierarchies. When there are multiple hierarchies used for the same dimension (e.g., Product and Color for a “Product” dim), the option to insert annotation disappears. There is still an option in the right-click context menu to add a “Notification” but once it is added, the red flag goes away on page refresh. Since cell-level “notifications” also leverage the cell annotations cubes, I think they share the same root issue. Please refer to the example below using Apliqo_Demo.

View is configured with “Product:Color” on the rows and “Product” in the title:

‌

On right-click, the “comment” option is missing

‌

If we modify the view so that “Product” dim is removed and only the “Coior” hierarchy is used, we are now able to comment and see existing annotations:

Hi Wei,

I'm closing this as this is expected behavior. Annotations are stored as part of a string. Although strings can be stored against consolidations in alternate hierarchies. TM1 can't store a string at the intersection of 2 or more hierarchies of the same dimension. This is why the option to store a comment isn't there when intersecting 2 hierarchies from the same dimension.

Thanks for the clarification on this Scott! I forgot about this limitation in TM1. It would be great if such functionality is added to TM1 sometime down the line, which would help drive wider adoption of virtual hierarchies.
