Hello olivier. majo 

'Delete row' allows you to delete only empty/manually added rows.

If you would like to remove any of the components from your BoM, you can hide the component in your structure tree and then, in the BoM properties, you can toggle 'Hidden Components' to 'Do not include'. (refer image).


This option will eliminate the components hidden in your Structure tree, from the BoM.

Is this what you were looking for? I hope I have addressed your issue. 

If not, could you please explain in more detail?
