Function CS_BOM_EXPL_MAT_V2

Hello,

I am using function CS_BOM_EXPL_MAT_V2 in one z report and I want to summarize the quantitie of a compoment if it appears more tha one time in the same BOM instead of having two items with the same component.

Does anybody know if is there a parameter of this function to do this or if I have to do it manually once I have obtained the result?

Thanks

Laura
