My this question relates to my earlier thread "Purchase order explosion at Product Receipt".
I have created a Purchase order for a BOM Item and posted a product receipt for that purchase order. The cost for that item had been updated.
Now I have created a BOM Journal, to split the BOM Item to BOM Lines.
Issue:
Physical quantity has been updated as per the defined BOM Version, but the cost from main item didn't allocated to the items.
Bill of Material

BOM Journal Lines

BOM - Transaction Lines

Q1: How to get the purchased cost of main item to BOM Line items?
Q2: What Main accounts to be used in order to get the correct impact on inventory asset account and to avoid posting it to expense account?
