Last modified Account Name of child record -> Parent layout via IWP
My question is similar to this.
I have a Sales Order layout which has a portal displaying related Payments. I would like to display the Last Modified Account Name as well as the Last Modified Date for the latest changes to a payment on the Sales Order layout.
I can use the MAX function for the Date, but not for the associated Account Name.
Have tried fiddling around with a lookup function, but I'm not getting very far. The payments will be updated via IWP, so I think script triggers are out.
Any help appreciated.
