BOM

we noticed that material 400011636705 is the direct son of the industrial code 759991676100, and it is expired.

we also noticed that material 400020000402 is another direct son of the industrial code 759991676100, and it is NOT expired.

but we also noticed that 400020000402 is direct son of 400011636705, and we believe that this is the reason why also the expired material appears in the resultset: because it is containing an active son.

MY QUESTION IS : Is it NORMAL? that a component is the direct son of an industrial and at the same time is the direct son of an expired component.

thank you in advance
