I had a quick look through the business logic and form, and it is very similar to that of the Manual Backorder Release thread you linked to. Same design.

Yeah I had a quick look with Just Decompile and had largely come to the same conclusion, it's just messy, basically stop Jiwa responding and re-implement that bit yourself.
I've already got a modified 'GetSalesOrdersToProcess' stored procedure ready to go with a specific, hard-coded 'LIKE' filter on Order No, but I thought it might be good to parameterise it.
