We have two lines.
L1: 100k
L2: 50k
AR applied $125k to line 1, but should have been $100k to line 1 and $25k to line 2.
Is there a way move the $25k extra out of L1 and apply to L2?
I’m not sure if you’re able to use this for advanced billing receipts, but you can use Adjust Cash Receipt to change how a receipt is applied. If you’re not able to use the adjustment window, you can use Reverse Cash Receipt to reverse the original receipt and then enter a new receipt for the correct allocations.
Both should be in Financial Management > AR > General Operations or Financial Management > Cash Management > General Operations.
will give it a try.
Miguel - Did either of these work for you? We have a situation where there is an advance billing balance on a Sales Order line. We had to move some of the line qty to a new sales order line and the advance balance actually applies to the qty on the new sales order line. We are looking for a way to transfer the advance billing balance on the prior SO Line to the new SO Line. Hope this makes sense 
We are able to use Deposit billing Credit Memo, as a step towards fixing most Deposit and Advanced bill issues.
