As part of our requirement under version 12.0.6, I am trying to assign order_number to oe_order_pub API instead of API letting choose its own number,however everytime it ignores the number that I have provided and assigns its own system generated seq no.Under what conditions does a sales order creation API allows one to feed in their own order number?

Any help in this regard would be greatly appreciated.
Thanks.

normally we’d use orig_system_doc_ref for the order no on migrated orders.

The other option is to change the document sequencing from automatic to manual and the order number from the api should then be used.
