Cant create a sales credit note - Process industries

Hi all,

I am having issues trying to create a credit note for an item that uses a stock model group that is set up to have same batch selection, and also a dimension group that has coverage plan by dimension checked.

So an example is that I invoice a sales order for an item with an incorrect price, so i then need to create a new sales order to generate the credit note to fix it. I select functions, create credit note, select the original invoice. When you press OK you get an infolog stating “Qty must be positive for same lot reservation”. This process works fine for items that are not setup for sames batch selection. The only way i can get it to work is to do a retrun order for the line and then generate a new order which is madness and cant be right.
