New UX - Copy/paste the entire row is pasted when operating on a grid with a nested axis
This item has been identified as an outstanding known issue. A workaround is provided until the issue is officially fixed.
In the New UX when copying a value(s) and pasting, the entire row in which the target cell(s) lies is pasted rather than the selected cells. This only occurs when using a single item which is a nested (inner) dimension. A temporary block on copy, paste and delete (using the delete key) has been introduced which will be removed once the fix has been implemented
Pivot the dimensions of the grid so that Line Items are not the inner nested dimension. Add a dummy item to the nested dimension to avoid the nested dimension ever having a single item
