Dear Satya
please check first the two existing documents:
Bill of Substance –Bill of material (BOSBOM)
Coming back to your screen; PAY attention. Refer to first document. we habe now more than one "BOM BOS" interface
Make sure that you have read the corresponding EHS BOMBOS Customizing (C1L0... represents the "classical" BOM BOS); the first FM: i do not know, the third one: could by the FM used by SPRC
check your environment parameter-"PROF001" must exists (as default usage); you should not use the BOMBOS_COMP as shown by you. The "main" idea of BOM BOS Is.
Using one BOM create one BOS; but here you have kliuested twice teh same VAT and then a thrid VAT
Sorry. No OSS note existing that I am aware of (a OSS conslting note as with SDS shipment) to help in BOM BOS set up
Depending on your scenario (please check SAP Online help !)
a.) REAL_SUB has assigned material
b.) or REAL_UB does not have assigned materia
Story is different. BOM BOS interface wasn't discussed in 2015 (if I remember correct)
