Hi,

I am working on a customer payment's before submit user event.My scenario is that on customer payment before submit event a lineitem is added to the current open invoice so the payment amount need to be updated to add the amount of the newly created invoice lineitem but on setting the line item of Customer Payment sublist following error is occured.

You have attempted an invalid sublist or line item operation. You are either trying to cannot access a field on a non-existent line or you are trying to add or remove lines from a static sublist.


if anybody has the resolution please share.
