Content

Dear ,

I want items unit cost in which i used table CST_TRANSACTION_COSTS ctc table then join into CST_INV_TRANSACTION cit

through ctc.CST_INV_TRANSACTION_ID = cit.CST_INV_TRANSACTION_ID

and then cit.INVENTORY_ITEM_ID = imt.INVENTORY_ITEM_ID (INV_MATERIAL_TXNS)

But issue is its does not show correct unit cost. Please guide me is there any other table or join which i joined to INV_MATERIAL_TXNS
