Currently if you are using the SOH report to reconcile / check the Invoice Summary, the report omits any quantities that are in a sale order status of "Packed".
This means that you have to run multiple reports to try and validate a storage charge.
Customers run the SOH report as it allows them to also view custom fields, which may be data points internally, e.g SSCC numbers.
Adding in the "packed" data for sale orders will allow a user to view all data from the one report.
