Hello Team,
In Sales Order we have option called Update Items after submit of sales order it will display. In that update items functionality if I add new item that item is not in existing sales order by adding new row and I try to update that item it is throwing an error like
Item ABC-00003 not found
The resource you are looking for is not available
if I add item from existing sales order item in that record it is allowing and updated in that sales order.
Regards
Nivedha
