This is just an FYI for others because I don't recall seeing it mentioned before.
When converting from MAS90 v4.3 to v4.40.0.6, we ran into an issue with weight calculations in sales order.
When invoicing orders that were converted from v4.3, the weight is calculated at either double or triple the actual weight. We also get funky weight totals when creating new sales orders from master orders that were converted from v4.3 or by copying from history.
So far as I can tell, with one minor exception, the weight calculates correctly when the order or invoice is created entirely within v4.4.
The exception is kits. We have always included the total weight of the kit in the weight field of the kit item. We explode all of our kits. In v4.3, only the component weights were included in the weight total in sales order entry and invoicing. In v4.4, sales order entry works this way, but sales order invoicing totals up the weight for both the components and the parent.
