I am facing another issue. i have pharmacy stock with two different purchase price . for example medicine name “ABC” entered in stock with 50 qty and 50 USD per unit price. and 10 days later, same medicine “ABC” need to be entered in stock but due to inflation price become 60 USD per unit. everything is fine at this point as both the purchasing have different invoice no to differentiate between them.
but the problem start when customer purchase medicine and operator enter details in following below code form . The gfg.php fetch data from stock table . But the issue is there can be more than one entry of same name medicine “ABC” in stock table with different purchase date and invoice no .
Now I want to learn from you that is it possible that in customer bill, when operator select medicine name, then medicine should be select from first entered stock. And when all quantity of first stock stock ended than it automatically select from 2nd entered stock and so on…
is it possible to manage or not ???
