Microsoft Dynamics NAV allows you to change the key that you use for sorting your data.
The following example illustrates how to switch to a different sorting key.
Open the 
Vendor Card
window and find a vendor that has ledger entries.
Click Vendor, Ledger Entries, and the Vendor Ledger Entries window appears. Scroll to the right in the window until you can see the Open field. The entries that are still open will have a check mark in the Open field.
On the menu bar, click View, Sort. The Vendor Ledger Entries - Sort window appears displaying the sorting keys that exist for the Vendor Ledger Entry table.
Select Open,Due Date.
On the frame under the keys, you can also determine whether the entries should appear in Ascending or Descending order. The default is Ascending.
To see the effect of the sorting without closing the Vendor Ledger Entries - Sort window, click Apply. If you are sure that you have the correct sorting order, click OK. The Sort window will close and you will return to the Vendor Ledger Entries window with the new sorting.
Sorting orders the lines according to whether they are open, and then by due date (the columns are not moved around). This gives you a quick overview of what you owe this customer.
The new sorting will apply to all vendors until you change it. If you want to look at entries for a different vendor with the same sorting, you can browse to the card for that vendor. The Vendor Ledger Entries window will be updated accordingly.
