Here are a few options to consider for this scenario:
1. Create two separate pricing procedures - one for industrial customers and one for domestic customers. Then assign the appropriate procedure to each customer group.
2. Create one pricing procedure but include logic in the condition formulas to check the customer type and apply the appropriate pricing logic (list price vs cost %).
3. Use customer classes to segment the customers and assign different pricing procedures based on the class. Then assign the appropriate class to each customer.
4. Leverage customer-specific pricing in the pricing procedure. Define different condition types for list price vs cost % and only include the relevant type for each customer.
So in summary, you have some flexibility around
