Cannot pass price list id via OKS_CONTRACTS_PUB.CREATE_SERVICE_LINE

 Hello,

I am able to use "oks_contracts_pub" API to create service contract base header & line successfully.  However, I cannot pass "price_list_id" through the line type record defined as below.  There's "list_price" in the record type but I don't think this is for accepting price_list_id.   It's high appreciation if anyone can give me a hint how to pass price_list_id through this API, or something else is compatable.

Thanks.

Quincy.
