I am trying to create a credit note in AX 2012 R3 and am having issues. I open the all sales orders form and highlight an order. I then click on the Sell tab and click the new Credit note button. This brings up a form that shows the invoices for this account, but it doesn’t allow me to select any of them. I try to check the boxes, but I can’t edit them. I have admin security, so that should not be an issue. What else could be wrong here or am I doing this wrong?
