Order Import Error - "Failed to insert the line into the set"

Hi All,

Using Oracle 11.5.10

The sales order is having setup to populate Ship Set and Fulfillment set for each line.

We are trying to import the sales order lines from external system with ATO model item. While creating lines itself, it does backend configuration and puts the lines to sales order.

But, during this process it fails with the below error message, and also it does not create any SO lines.

One of the group attributes failed your scheduling attempt. You tried to perform a scheduling action on a schedule group (ATO Configuration, Ship Complete Configuration, ,Ship Set or Arrival Set) and since one of the group members failed it caused the entire group to fail.
