Backflush Materials Page Splits the Lot Incorrectly When Work Order Transaction UOM Differs From Primary UOM (Doc ID 2565401.1)

If the Lot Selection During Backflush is set to "Lot FIFO" or "Lot FEFO", Backflush materials page in review dispatch list on completing with details is not considering the UOM on item structure/work definition but splits the lots where primary UOM on item and UOM selected on the item structure differs.
So for e.g. if a lot has 10 kilograms and work order has requested for 100 grams, the work order dispatch splits reads quantity into 2 lots 10 grams and rest of 90grams required for completing work order another lot.

Lots should not split since enough quantity is available on a lot to issued out to the work order. So for e.g. if the work order requested 100grams and a lot of 10 kilograms is available, that should be the only lot assigned to the work order line during dispatch.

The issue can be reproduced at will with the following steps:
1. Create an lot controlled item with UOM as kilogram
2. Create a finished product that will have this lot controlled item in its item structure as a component.
3. In step 2 which creating the item structure, change UOM in the bill for structure to grams instead kilograms and quantity required as 100 grams.
2. Ensure the Manufacturing Parameters have "Lot Selection During Backflush" set to "Lot FIFO"
3. Create a work definition with one single operation.
4. Create a inventory miscellaneous receipt for item created in step 1, to receive the item into the supply sub-inventory with the first lot having 10 kilograms and create another miscellaneous receipt with another lot having 100 kilograms.
5. Create a work order and release it.
6. In review dispatch list, select the work order and click 'Complete with Details'
7. See that for the item created in step 1, there are 2 lines for the operation, first line with lot having 10 grams and another lot number with 90 grams.
8. The issue is it could have been one lot with 100 grams since first lot has 10 kilograms and enough material to transact the work order.
