The system has a flaw in the validation logic when generating credit notes. Currently, the software allows returns of an item for a quantity greater than the amount originally invoiced, as long as the total amount of the return does not exceed the total amount of the invoice.

EXAMPLE

On an invoice with a total value of $40 (composed of 2 units of Item A at $10 each and 2 units of Item B at $10 each), the system allows you to create a credit note by returning 4 units of Item A. The system accepts the operation because the value ($40) matches the total of the invoice, ignoring that only 2 units of that item were sold.

SALES INVOICE

ITEM VALUE TOTAL QUANTITY

TO 10$ 2 20$

B 10$ 2 20$

TOTAL BILL AMOUNT 40$

CREDIT NOTE

ITEM VALUE TOTAL QUANTITY

TO 10$ 4 40$

This creates a serious inconsistency in the inventory (units that never came out come in), causing physical stock mismatches against the system.

I WOULD BE VERY GRATEFUL TO THE ALLIADDO TEAM IF THEY COULD PLEASE FIND A PROMPT SOLUTION TO THIS ISSUE, SINCE HUMAN ERROR IS POSSIBLE AND KEEPING THE INVENTORY IN ORDER IS ESSENTIAL. ADDING THIS VALIDATOR WOULD GREATLY REINFORCE COMPANIES THAT HAVE A HIGH INVENTORY FLOW.

THANK YOU VERY MUCH
