How to update end_date_active of price list using API qp_price_list_pub.process_price_list

Hi,

I am using qp_price_list_pub.process_price_list API to update the the end_date_active of price list.

It works fine for the price list lines and updates the end_Date_active field of lines but it does not update the end_date _Active field at price list header level.

Please suggest.

I am passing following fields :

  gpr_price_list_rec.list_header_id := 10696338;

      gpr_price_list_rec.list_type_code := 'PRL';

      gpr_price_list_rec.SOURCE_SYSTEM_CODE := 'QP';

      gpr_price_list_rec.operation := qp_globals.g_opr_update;

      gpr_price_list_rec.END_DATE_ACTIVE := (sysdate);
