Hi Venkateswara,
According to your question, I understand that 2 things:
1. The structure shown is not made by you.
2, You are going to the Functional Location Master (of the Functional Location half seen in your picture) and searching for the material.
Answer:
1, Your picture shows a F/Locn BOM.
2. You'd not find any of these this materials inside the F/Locn Master.
3. You'll find the Material directly under F/Locn (i.e.3018568), through Tcode IB13 (Functional Location BOM) and putting the F/Locn value in the initial screen.
4. You'll find the rest of the Materials through Tcode CS03 (Material BOM) by putting the above material (i.e.3018568) in the initial screen.
