sales bom for dien material

hi ,

I´m trying to create a sales Bill of material with dien material ( non stock and non value material). But I don´t if my configuration is correct.

the material at the top level is dien with erla item group.

the subitem is dien material with norm Item group.

I create a sales BOM for services but it does not explode IN vA01 and I receive this message:

The system did not find a valid bill of material

Message no. V1113

The configuration in header material

item material

thank you in advance
