Because When some time if I goes to Shipment Cost Item and double click for the condition, its shows some red condition type.
What is the basic difference?
Answer:
Whether Delivery Items or Shipment Cost Item appearing in the shipment cost document is dependent on the settings you configure in your shipment cost condition types (under Freight Costing --> Calculation Base).
For example:
You can have different pricing procedures for your shipment legs, header, load transfer point etc.
Where a Delivery Item calculation base is set - In your shipment cost item (when you double click), there will be sub-items created for each item in your delivery document.
Where a Shipment Cost Item calculation base is set - In your shipment cost item (when you double click), there will be exactly one shipment cost sub-item determined for your shipment. However, you will not obtain individual sub-item per delivery item.
I.e. for shipment cost item, if the accesses for your shipment cost item category uses the condition type with "Shipment Cost Item" as calculation base which include the Carrier, Company Code, Route or other information (which contained in the shipment document etc.), then this item will be calculated and value will be shown in the item category --> sub-item level.
As for your query why some conditions are showing in "red" in the sub-item level of the document, you may click on the "Analysis" button to check the underlying problem. In most cases, it is mainly due to mandatory conditions set with no master record maintained, incorrect calculation etc., which you need to check further in other areas.
The significance of these settings differ from one company to another and it largely depends on the requirement of the organization on how the shipment cost should be calculated - either for each delivery items, or for each shipping units, or the entire delivery itself, or shipment item itself.
