Where is Low Level Code of Baan IV in LN?

Where is Low Level Code of Baan IV in LN?
Baan IV Field was tiitm01.llcd

I tried to look at cprpd100 for field mrph but it seems doesn't have the right info.
IS there any session which can rebuild the this BOM Level Code?

My main interest is to find the BOM Level code in Multi Level BOM environment.

Thanks
