Calculation of the optimal packaging result

Extended Case Calculation – optimal planning for packaging and palletising

The topic of packaging planning has become increasingly important in logistics in recent years. It costs time and money to ensure goods are optimally packed for storage, internal material flows and shipping. Optimised packaging thus gives you an edge over your competitors and helps to improve your market position.

The following applies to package and transport planning as well as packaging in shipping. The primary goal of packaging planning is to achieve a reliable and optimal pre-calculation of the shipping units, so that the customers can be guaranteed the smallest possible packaging – with zero transport of "air".

Application areas

The pick-and-pack process is frequently used in the e-commerce sector. In this process, the goods are packed directly into the order package during picking. This eliminates subsequent packaging in shipping, which saves both time and money. With this concept, the size and contents of the shipping packages are already calculated in SAP EWM or SAP TM during production planning.

With traditional packaging methods, the shipping process can be very time-consuming and costly if many articles need to be dispatched. Again here, the suggestions generated during packaging planning can provide efficient support for your staff. To obtain an exact preview of the required cargo space for shipping or to implement either a system-based or fully automated palletising process, the calculated shipping units are re-planned as required in a second level of palletisation planning.

Using SAP EWM/TM Extended Case Calculation, all goods intended for storage, internal material flows or shipping can be optimally, cost-effectively and safely packed, palletised and shipped via guidance from the system.


Particularly in the e-commerce sector, in which there are typically only a few articles per shipping package, over-packaging errors can occur when using standard SAP EWM/TM packaging planning with water displacement. Despite volume reserves, it may be the case that the articles cannot be efficiently arranged in the shipping package due to their shape. This results in time-consuming repacking or flat-rate "shipping of air" by reducing the maximum volume for the calculation.

SAP Standard Case Calculation


  • Overpacking errors despite volume reserves
  • The shape and arrangement of the goods are not taken into account when calculating with water displacement
[Translate to English:] Optimisation SAP EWM / TM Extended Case Calculation


  • Uses a simple stacking pattern algorithm
  • Optimal packing pattern and optimal use of packaging
  • Overpacking errors are eliminated
  • Different calculation heuristics (water displacement, stacking pattern, etc.)
  • Visual representation of the packing results
  • Intuitive 3D packing instructions for order pickers and packers
  • Packing simulation using a load preview or cargo space preview
  • System-supported validation of article master data
  • Consideration of the influencing parameters, such as the inventory situation, storage topology, packing rules and packaging prohibitions
  • Consideration of the articles' condition and similarity (e.g. bundling of "bar-shaped articles")
  • Consideration of customers or forwarder-specific packaging and restrictions (e.g. customer specifies maximum pallet height)
  • Highly efficient packing algorithm developed in partnership with the Frauenhofer Institute
  • Multi-level planning for packaging and palletising
  • Calculation of the optimal packaging size
  • Optimum filling of the shipping units
  • System-supported 3D packaging instructions
  • No transport of "air"
  • Reduction of transport/shipping costs
  • Avoidance of transport damage

The reliable and optimal pre-calculation of the shipping unit is the main objective of the packaging planning, so that the customer can be guaranteed the smallest possible packaging and no transporter of "air".
