Manual addition of line item allowed in Outbound delivery

Question

Dear Experts,
         In the "Outbound delivery" document created with reference to "sales Order" if we tried to add one more line item manually then, system is accepting that line item without any warning / error message.
            but as per our requirement system should not allow to add manual line item in the delviery document. So can any body give some suggestion on this to solve the problem.
In the copy control from Sales Order to delivery we maintained the following setting.
In the header level,
Conditions
Order requirements     001    Header
Combination requirmt   051    Combination
Data Transfer
Header Data            001    Header
In the item level,
Conditions
Order requirements     101   Item
_Data Transfer_
Item data              101   Item
Item Ext. System
Business data          2     Business Data
Warm Regards,
Vel

Hi Lakshmipathi Sir,
A related question on this:
Lets say I have an STO of 100 EA. When I create the Replenishment OBD, system will automatically copy 100 EA into the delivery.
Now user wants to split this line into 2 lines into 60 EA and 40 EA.
User will change the first line from 100 to 60. So far so good!
Now I want to add the additional line with the remaining open quantity. Is there a way to do that?
Regards
Siddharth
