The Setup tab shows the information about a certain packing slip.
The Purchase manager can change the transaction date and the document date.
Let’s assume that the vendor delivered items on March, 9 with a packing slip document. The Purchase manager was ill on that day. But, the warehouse worker still receives the items and places them to store in the warehouse on March, 9. The Purchase manager comes to the office on March, 10. He or she needs to post the packing slip document backdated. In this case, the Purchase manager clicks the Setup tab and enters March, 9 in the Packing slip date field.
