If you really want to Add inventory for this Item number without providing a Serial Number, you must ask your MobileInventory administrator to disable the Track By Serial Number option first. This can be done by using Administration, List Forms to locate the Item, highlight it, then click the Edit Item toolbar button (the one with a yellow pencil on it) to bring up the Edit Item dialog. If the Item to be Tracked By Serial Number option is NOT grayed out, you will not be able to disable the option and then return to doing an Add Inventory function - the Serial Number field will no longer be required and Quantities greater than 1 can be entered. If the Item to be Tracked By Serial Number option IS grayed out, you will not be able to disable the option until you first Remove all inventory that has been Added for this Item. If you want to proceed with this, you'll have to do the following: Return to the Item table, highlight the Item and then click on the Remove Inventory toolbar button (the one with the minus sign). One at a time, you will have to do Removes, entering the Serial Numbers that had previously been entered with Add Inventory transactions, until you zero the Total Available Quantity for this Item. Then, you will be able to use Edit Item to remove the checkmark in the Item to be Tracked By Serial Number option. Afterwards, you can use Add Inventory (the toolbar button with the plus sign) to Add the quantity that you just finished Removing, but this time, you will not be supplying Serial Numbers.
