Priority between Plant Specific and X-Plant Material Statuses

Hi,

I am wondering which is prioritized, Plant Specific Material Status or X-Plant Material Status.

The official help below suggests that the X-Plant Level will be chosen, however, the logic behind is unclear. Does the X-Plant is chosen because:

1. Client level setting is always prioritized to the plant-specific level
2. blocking in Inventory Management covers a larger area than blocking for Purchasing, i.e. more strict status?

In the QA below, the questioner received the answer to use Plant Specific Material Status solely to meet his requirement.
