Oracle EBS :Inventory:Item Cost
For discrete manufacturing:
cst_cost_api.get_item_cost(1, inventory_item_id, organization_id,NULL,NULL)
here is a sample query:
select segment1 item,
cst_cost_api.get_item_cost(1, inventory_item_id, organization_id,NULL,NULL) cost
from mtl_system_items_b
If you are in an OPM organization the above won't work and instead you need to call
select msi.segment1 item,
GMF_CMCOMMON.get_cmpt_cost( inventory_item_id, organization_id, sysdate, cmm.cost_type_id ,0) cost
from mtl_system_items_b msi, CM_MTHD_MST cmm
where cmm.cost_mthd_desc='Standard Cost'
