oe_blanket_pub.process_blanket not creating new price list in Oracle 11i

I am trying to Import Blanket Sales Agreement using oe_blanket_pub.process_blanket API. I am passing values as below but API is not created New Price list. Even none of the pricing Columns at the line level are imported. BSA is getting imported without Price List information and also no error messages are returned.

Are there any other specific columns for which I need to pass the value?

For New Price List Name -

l_hdr_rec.new_price_list_name := hdr.new_price_list;

For Line Pricing Columns

l_line_rec.unit_list_price := lines.unit_list_price;
