In New Purchase Order view, when you edit the items in Items table, you will receive error message if you change the Process Type directly without changing the lead selection. For example, you are changing the Process Type for second line item but selection was on first line item.

Reproducing the Issue

  1. Go to Purchase Requests and Orders work center
  2. Purchase Orders view
  3. Select one Purchase Order and choose Copy
  4. In the screen that opens, change the Process Type to a new value for the second item. For example, change the value from “To-Stock” to “Non-Stock”.


When the Process Type is changed from “To-Stock” to “Non-Stock” for the second item, the lead selection by default is of item 1.


Change the lead selection to item 2 firstly, and later change the Process Type for item 2. Then the issue will be resolved.
