[development-axapta] Multiple Invoice Printout sort order

[stephan.vanniekerk]

How do I change the Printout sorting order for printing multiple
Invoices from

Sales Ledger > Periodic > Sales Update > Invoice

Currently the printouts are sorted by Sales Order number. I want to
sort it
by Customer Description to help the customer to file them easier. Changing
the “Sort Order” on the Sorting tab on the Selection screen doesn’t make a
difference.

Thanks,
Stephan
