EGO_ITEM_PUB.ASSIGN_ITEM_TO_ORG not working as expected

Hi Experts,

We have a requirement to assign the inventory items from master Org to new child org. We have used the EGO_ITEM_PUB.ASSIGN_ITEM_TO_ORG seeded API for this requirement. Its almost working fine. But few columns are not sync with master Org Items , eg: (EXPENSE_ACCOUNT , COST_OF_SALES_ACCOUNT , SALES_ACCOUNT ,PLANNER_CODE in Item master table).. Snippet of the logic is mentioned below. We have passed both inventory_item_id,Item_number,org_id and org_code ... Is there any restriction for this API ? We have already gone through the oracle notes related to this API , but did not see anything unusual. Your inputs would be greatly appreciated.
