How to handle different varients of same item without code generation everytime

Hello!

So… we have a machine that has 5 sub assemblies and 150 parts.

Every size of this machine has exactly 5 sub assemblies and 150 parts. only they change in size and thickness.

What i want to know is that

Can i have a single SAP item Code with multiple Variants. For e.g.

SAP code for “base plate” can be 10000168789

now it can have multiple varients linked to different drawings.

variant 1 – 10000168789 linked to Document number 123456

variant 2 – 10000168789 linked to Document number 654321

and so on….

if this is possible then how to do it?

Thanks in advance.
