I HAVE PARTS THAT HAVE SERIAL NUMBERS, I NEED A WAY THAT IF I PUT A PART INTO INVENTORY THAT HAVE SERIAL NUMBERS WHEN I ENTER THE QTY OF PARTS I FIELD WOULD OPEN UP WITH A DROP DOWN LIST OF BOXS THAT TOTALS THE NUMBER OF PARTS ENTERED AND YOU GO DOWN THE LIST AND ENTER ALL THE SERIAL NUMBERS ,WHEN ONE OF THE PARTS IS MOVED FROM INVENTORY A DROP DOWN WOULD OPEN SHOWING ALL THE SERIAK NUMBERS AND YOU SELECT THE PART FOR THE INVOICE AND IT WILL REMOVE THAT ONE FROM STOCK,
AND IF YOU RECEIVE MORE OF THAT PART ENTER THE QTY FOR STOCK AND A WINDOW WILL OPEN FOR YOU TO ADD THE NEW SERAIL NUMBERS

THESE TWO ITEMS ARE VERY IMPORTANT FOR INVENTORY CONTROL DOCUMENTS AND SERIAL NUMBERS AND FROM HERE YOU CAN ADD BAR CODE TO FURTHER IMPROVE TRACKING AND QUALITY OF THE INVENTORY SYSTEM
