How to use CS_BOM_EXPL_MAT_V2 to include bom under Phantom

Question

Hi every1,
How can I get documentation for this function module CS_BOM_EXPL_MAT_V2 
We want to explode BOM on single level ,including Material which is coming under Phantom assembly too.
eg. I have one material 1xxxxx.
after exploding single level bom suppose I'll get these material
1xxxx1
1xxxx2
1xxxx3 and if 1xxxx3 is Phantaom assembly and under this item again I may have 1xxxx1 as bom item.
that means for my parent material 1xxxxx, I want 1xxxx1 should come 2 times !
Is there any simpliest way to get or for this item again I need to use this FM again ?
Pl. do help me.
Thanks in Advance.

Hi,
THE FM 'CS_BOM_EXPLOSION_MAT' mentioned above holds true if u dont hv any alternatives for the BOM.
eg: If ur component in turn has BOM with 3 alternatives namely 01,02,03
then ideally FM should pick all the items uder these 3 components but this FM picks by default the 1st
alternative & ignores the rest.
So there are changes dat the list which u hv gpt is not 100%.          
  Through Tcode CS12 u can see the level wise components for a BOM.
U can gather the component details with this Tcode if u hv very few BOMs to explore.
But if the count is higher u hv to select acoding way for it....
Attaching a part of code to explore multilevel BOM.....hope dis ll help u......
