CK11N - Cost Component View (Not Assigned Materials)

Hi Experts,

While executing Material Cost Estimate, i found that some of the materials which belongs to Raw Material Type were shown as (Not Assigned). Attached is the screen shot which shows only one material as raw material and rest are shown as not assigned:

I have checked following settings:

- Cost Element 600000 is assigned on Cost Component Structure (OKTZ)

- All non assigned materials are marked as With Qty Structure and Material Origin under Costing 1 View of Material Master.

Please guide.

Regards,

Zain Bashir
