Sales Information System : Variants S138

hi,

We need sales figures for our different materials configuration.

f.e material XY is sold with variants 1 and 2 with each their prices. Also i made a planning profile with the char's i want to report on.

I copied structure S126 to S137 with method v003 and then S137 to S138 without method.

Suppose sales figures for XY1 is 100 (sold 1 unit) and for XY2 150 (also 1 unit)

In transaction MC(b , i am able to consult total sales of material XY eg 250 but when i drill down to the variants i see the right number of sold units per variant but not the sales figure per variant.

Is this normal ? When i look at structure S138 i see everything is aggregated but in S137 there is a clear distinction.

with regards

Erik
