How to Automatically Recalculate the Price When Selecting a Lot?

In a sales invoice, when a lot is selected for one of the items, I need the system to automatically update the price if there is a custom price for that lot in the price list, or if the lot is included in an offer that includes a discount. Note that the system already recalculates the price correctly when the quantity is modified, but this requires manually changing the quantity after selecting the lot.

Solution: To achieve this, you can set up a GUI Post Action linked to the lot field (lotId) that triggers the GUI Post Action of the quantity field (primeQty.value). This linkage ensures that the system recalculates the price immediately after selecting the lot without the need for a manual quantity change.
