Change the financial dimension on a pending vendor invoice that is created via import, should not have the unit price deleted, as changing a dimension should not affect the price. If the pending vendor invoice is created manually the unit price is not deleted.

This was reported as a bug but will not be changed by MS:

Microsoft has evaluated this request and will not be pursuing a fix for this issue as this will bring quite a lot of effort to fix it. In the meantime, it has a high risk of affecting the existing functions.

Before we spend the effort on fixing it, we'd like to gather more feedback and see how many customers have been impacted by this problem first.
