Same customer with different discount

Dear Expert,

Kindly your help, currently we devide the customer number means one customer can have 2 or 3 customer number , we devide as follow;

customer No customer name business transaction

1. 1001 xxx vehicle with discount

2. 2001 xxx vehicle without discount

3. 3001 xxx sparepart

Additional info currently we are using BO01 and BO03 in the pricing procedure.

We also already separate with pricing procedure, sales organization and distribution channel, my question is how and where to maintain so I can have only 1 (one) customer number for both with discount and without discount by delete the pricing condition (BO01 and BO03). Thank you

Best regrads,
