Order Import Error - "Failed to insert the line into set. The line could not be scheduled on the set

 Dear Friends,

I am facing the below mentioned error during order import:

"Failed to insert the line into set. The line could not be scheduled on the set attributes and could not schedule the whole set on an alternative date"

In the OE Lines interface table, no ship set is mentioned. But in the customer master setup, under the order management tab, i could see the "Ship Sets" option checked. 

So oracle will try to assign all the order lines into single ship set.

Based on the error message, i see that some of the order lines could not be scheduled and because of this oracle tries to schedule whole set on an alternative date but fails to do so.
