Why API qp_price_list_pub.process_price_list is not creating qualifier successfully ?

Hi,

I am using the below piece of code to create qualifier for a price list using qp_price_list_pub.process_price_list API  .

The return status is success but I dont see qualifier created in the application and not in the tables as well.
