Delete internal order

Question

We have an issue where we have an internal order that we would like to delete but cannot. It comes up with a couple of messages See below:
Let me know if you think you can help.
Thank you
Balance of ORD 100620 is not zero
Message no. KO 115
Diagnosis
You can only set the delete flag in an order once it no longer contains any costs, i.e. when the balance is zero, unless it is a statistical order.
The current order balance is
ORD 100620 in order currency
in controlling area currency
System Response
The delete flag cannot be set.
Procedure
To be able to set the delete flag in the order, you must settle it first.
"NOTE IT DOES NOT DISPLAY ANY BALANCE"
Order 100620 still has at least one purchase order that you need to delete.
Message no. KO 013
Diagnosis
A purchase order assigned to order 100620 still exists.
System Response
You cannot delete order 100620.
Procedure
You must first delete all purchase orders assigned to order 100620. Select the affected purchase orders with the "Search help G".
Process purchase orders
If you still want to mark orders for deletion (on which purchase orders are still assigned), you can change this message from an error message to a warning. In this case, the system checks that each order does not contain any open commitments. To change the message, use workstep " Adjust message control" (Application area "KO", message number "013").

Answer 1

Hi,
It appears there is a purchase order assigned to this internal order. You can change the error message KO 013 to a warning via transaction OBA5. Select 'application area' KO and on the next screen you can define message 013 as a warning.  
Alternative is to archive the PO and then set the deletion flag on the internal 
order.
