Unable to change empty BOM with IB05

Hi,

Because we handle a lot of customer Equipments we setup the Equipment's structure at the start of the intake proces. The only thing we know is that the customers structure may have NON-serialized items, we don't know the exact materialnumbers before it has been taken out physically, for this reason we only create a Group-BOM header.

Unlike IB02 you can not change a empty BOM with IB05, once created you can only modify the BOM structure using IE4N, causing an installation with Goods movement. (261E)

Is there another way of changing a empty Group BOM?

Regards,

Bas
