Pick slip generated from a maintenance order is not updated when inventory changes

Summary:

When a pick slip is generated from maintenance, the following scenarios occur:

There is no inventory of the product. The pick slip does not reach  the warehouse; If inventory arrives, the user must generate a new pick slip.

A pick slip line is partially attended to. The line disappears and the user must make a new pick slip for the balance.

In both cases the work order continues to need the material but the warehouse is not aware of it. This disinformation affects maintenance performance.

Is there a way for the lines  without inventory to reach the warehouse and for the partially attended lines to remain "alive" in the pick slip?
