Work Order Billing using Price Modifiers

Good Day All,

I have created a price list with the billing Item and created a modifier (Discount based on Customer) for the billing item.

When i do the billing, the price is being picked from the price list but the modifier (Discount) is not being applied for the billing.

Q) Does the modifiers work with work order billing and did any one try this before?

Your inputs in this regard will be highly appreciated.

Thanks and Regards
