Hai,
Example :
I have two variant colour (RED, WHITE and BLACK ) and voltage (6V, 12V and 16V)
I created Characterstic in CT04 for Colour and voltage
I create Class 300 and 200 in CL02 in that in assing the characterstics colour and voltage
I Create Configuration material KMAT and i assign the class Note : i didnt select any variant
I create seperate material for each variant RED, White, BLACK, 6V, 12V and 16V
I create dependency in CU01 select pre-condition and create dependency. I did same for each variants
Then That dependency i assigned in BOM and Routing
After all assignment done then I check the result in CU50 by selecting the variant RED and 6V then I checked the result it viewing all variant which is in the Super BOM
