Hello @vs.sukesh 

I am not aware if there is a functionality based on quantity. But there is a control based on order amount. You can consider using Min. Sales Amount field.

Min Sales Amount:
The minimum net amount that should be sold to the customer per order (expressed in the base currency). This amount is excluding the charges and taxes. If the total order value is less than this, a message appears when you release the customer order or sales quotation.
 

If you need to do this by quantity, I think you can create a custom error message if the quantity is below certain threshold. 

Hope this helps

There are also the options of 

1. Creating a gradated price list where the price is higher per each if the quantity is low.
2. Creating a complimentary non inventory article that can be added manually or automatically  when the article is entered on a customer order. You can create customized events to handle the  complimentary item

Both of these options can be combined with a document text on the order confirmation that presents the steps on the price list. But then you must remember to update that document text manually when the price list is updated...

@vs.sukesh you could:

• create a custom field at CO Header level to calculate the weight of the inventory parts in the CO
• define a custom event to be triggered when CO is Released → the event should add the charge line in the CO if the CO weight < 500 kg

Hi,

It is likely too much for this specific requirement, but IFS Transport Administration could be utilized for this. The functionality is used to automatically generate Sales Charge lines for Customer Orders based on the weight or volume of the customer order and the delivery address, i.e. to calculate the freight the customer should pay. It includes functionalities for a minimum freight amount and a freight free amount. I suppose there could be a setup which would not generate any other charges than the charge for a delivery that is too small.

Example: freight to a certain geographical area is priced to be 0.5 € per Kg with a minimum freight amount of 250 € and a freight free amount of 251 €. When the customer order is for 380 Kg, the freight is be calculated to be 190€, but as it is less than minimum amount of 250 €, a charge would be generated for 250 €. If the customer order is for 580 Kg, the freight is be calculated to be 290€, but as the freight free amount is 251 €, no freight would need to be paid.
Of course, if the freight calculation in general would be useful, the freight free amount could not be set at all, or be set higher; this was just to make a scenario where freight is only to be paid if the total weight is too low.
