You can make the setting in delivery item category by going to the below path
IMGLogistoics execution -Shipping-Deliveries ---Define item categories for delivery (OVLP)
Maintain Check minimum quantity "B"
By doing the settings also it will not work in case of deliveries made reference to STOs.
As you can see from note 548914 this functionality doesn't exist.
Kindly check the below link
The system does not check the delivery quantity in the delivery with the STO quantity ,in which delivery created with reference to the STOs .
The configuration in delivery item categories for over delivery will work only for sales order references and not for STOs
so i suggested to use the BADi to control the same
If you want to avoid this, goto transaction 0VLP and in "Check Overdelivery" field for your item category, fill the value "b".
You will get an error when you create delivery.
If you will maintain this, you will also get an error in VL04.
Otherwise, this is standard SAP behaviour that you can increase the qty in VL02N.
Have you also specified some over delivery tolerance in your customer master or customer-material info record or sales order.
If yes then system will consider that tolerance before giving the error message.
Otherwise the configuration should work. I have used this in many projects.
I am really very sorry for wrong spell of your name.
For other scenario whrere i am using NL as delievery type and NLN as item category I am getting a message VL339 you cannot change the item no. will you pls brief about this message and its setting. I am very close to solve the issue pls help.
Through standard configuration it is not possible
It has been discussed many times this issue
Over delivery in STO can be controlled by userexits or BADI only
Delivery item category configuration will not work (0VLP settings will work for only deliveries initiated from sales orders )
Yesterday too this issue was discussed
Enclosing herewith the thread fro your reference
In that MM thread is there which clearly answers you
