Hi all i have difficulty in packing slip posting of sales order , I want to update packing slip number - 'PO00001' while packing the SO and not sure how to do that.
normal SO packing slip
// SO packingslip
salesFormLetter = salesFormLetter::construct(DocumentStatus::PackingSlip);
salesFormLetter.update(salesTable,today());
that is how we do normally here i want to update a particular number for packing slip like how we do in purchase order packing slip.
