Extract Multi Level BOM

Hello

I am working with a huge assembly which containts lot of sub assebmly and again another sub assemblies inside that. Is there any way to extract the multilevel BOM as Level 1, Level 2, Level 3 upto last level.

For example f i working in Assy. called A (Level 0), then sub assembly (Say B, Level 1) or direct part (Say C, Level 1) insde A is Level 1 if any part inside Assy. B is level 2.

Like this is ther any way to extract.

thanks in advance
