We have issues with calculating issued package item weights.

We need the information on package item level, how much weight has been issued and how much weight is still available in the inventory.

For this I suggest to convert the existing database field Total Material Weight on Package Item with a Weight per Piece column, which is then multiplied by the Packed Quantity.

There should be additional calculated weight fields on Package Item:

These calculated weights would be helpful on Package level as well.
