Hello,
I have been using NAV since 3.7 and have never encounter this issue before so I'm wondering if this is a bug in NAV 2018. I have not been successful in searching for anyone reporting this. This client is using NAV2018 with no customization in this area. When you are in the deposit screen and you select Function--> Apply Entries, I set the Applies-To ID on multiple lines. However on one of the lines, I change the Amount to Apply so that I am apply less than the invoice amount to match up with the total deposit. The remaining balance on the bottom right will show zero. However, when I close the screen, and go back into the apply customer entries screen, the Amount to Apply reverted back to the full invoice amount. Originally, I was changing the last line but even if I change the amount to apply on another line, same result.
Has anyone see this occur before? Apparently, the system is posting the over application so that the payment lines in the customer ledger entries is showing a positive remaining balance. Which I have never seen either.
