One or more Ship Sets on delivery <nnnnn> are incomplete.

Hello

Am attempting to update a delivery and do a partial ship confirm.

Say the customer ordered 3 items , but we are only going to ship 2

We want to update the delivery line to change the shipped qty to 2. This is achieved by calling the api :

wsh_interface.update_shipping_attributes and these parameters :

  l_shipping_attr(1).cycle_count_quantity:=1;

   l_shipping_attr(1).shipped_quantity:=2;

l_shipping_attr(1).action_flag := 'B';

This creates a backordered line on the Shipping Txn screen.

Then , to do the ship confirm we call this api.

wsh_deliveries_pub.delivery_action(

However as the back ordered line and shipped line both have the same ship set id , I am getting this error:
