Modify the Automatic Lot Assignment feature of the invoicing system to use the following process:
1.Review the lots from oldest to newest and assign the entire line item to the first lot which has inventory.
2.If no lots currently contain any inventory, assign the entire line item to the newest of the empty lots.
3.If no lots exist for a given item, create a "placeholder" lot with the Lot Number of "DUMMYLOT" and assign the entire line item to this lot.
The proper operation of this feature requires System Option #106 - "Auto lot assignment while adding invoice items" to be enabled.
