Tuning Oracle Applicatons Order Management Query

Question

Hi
We are trying to build a Order Management related workbench for this I have created below query as per the client requirement.
And I have to use one package function to get Available_qty based on client defination. Package Function name is "xx_eg_calculated_onhand".
User will query this view based on Customer_id and Salesperson_id. When this view executed with these two values its taking long time.
But, if user queries with order_number it is getting executed fastly. Could somebody let me know what should I do to get this query execute fast when
user query with either customer_id or salesrep_id OR both.
