R12- Inventory Item Assignment -Sales Account

Hello,

We are using inventory . Order Management and all financial modules. We have a multi org setup having multiple inventories and sub inventories.

We have sales in different sectors and sales account(natural account) needs to be different for each such sales.

When we define an item , sales account defaults from Inventory Org set up, we change the Sales account, at the master item  level and save the record, However when we assign the item to other Organizations, the account which is changed at master item level is not picked up, but the account which is defined at Inventory Org is taken.
