Production order cycle

Hi All,

I have a question on Production order(PO) processing of serialized /non serialized items. 

PO - Main item (non serialized)

I create PO with main item as non serialized item and quantity 2, in the inventTrans i see the PO with one line.

PO - Main item (serialized)

I create PO with main item as serialized item and quantity 2, in the inventTrans i see the PO with 2 lines. Based on the quantity the lines are split up in inventTrans table.

If this is the case for serialized and non serialized items, why does it differ for BOM items??

PO - BOM item (serialized/non serialized)

When i estimate the PO, BOM items are updated in inventTrans table. If the BOM item is serialized or non serialized, the lines are not splitted in inventTrans table. 

Screenshot for main item(serialized) and BOM item in inventTrans table.

Qty - 3

Main item - 10033451 

BOM items - 10018968, 10033452(serialized but lines are not split up), 10033453 

Screenshot for main item(non serialized) and BOM item in inventTrans table.

Qty - 3

Main item - 10000004

BOM items - 10000001, 10018234

Any knowledge sharing would be greatly appreciated. Thanks in advance.
