In the form Work details, and on the Document Shipping pick list for wave, for product variants, the product variant name ("T-shirt Blue Large") should be displayed instead of the product name ("T-shirt").

Proposed solution: adding this.inventDimId in the argument of the display method WHSWorkLine.displayItemName()

public display ItemName displayItemName()
{
return InventTable::find(this.ItemId).itemName();
}
