| # Handling unit dimensions, example D This example shows how ERP LN calculates the dimensions of handling units with external packaging items. Example The parent handling unit has a user-defined external packaging item called Pallet. The parent handling unit has one child level consisting of eight child handling units. Each child handling unit has a user-defined internal packaging item called Box. The dimensions of the individual packaging items of the handling unit are as follows:
Dimensions | Pallet | Box
--- | --- | ---
Width | 1 m | 0.5 m
Depth | 1 m | 0.5 m
Height | 0.2 m | 0.5 m
Floor Space | 1 m2 | 0.25 m2
Volume | 0.2 m3 | 0.125 m3
Using the dimensions of the previous example, the dimensions of the parent including the child handling units are as follows:
Dimensions | Parent | Explanation
--- | --- | ---
Width | 1 m | This is the width of the external packaging item.
Depth | 1 m | This is the depth of the external packaging item.
Height | 1.2 m | The surface areas of the pallet and the boxes determine whether the boxes must be stacked to fit on the pallet. The value in the Height field of the Handling Units (whwmd5130m000) session shows the height of the stacked boxes added with the height of the pallet. ERP LN calculates the height of the handling unit as follows: Add the aggregated volume of items or internal packaging items to the volume of the external packaging items Divide the result by the floor space of the external packaging items The volume of each individual internal packaging item is 0.125. The aggregated volume is therefore 8 * 0.125 = 1. The volume of the external packaging item is 0.2. This gives the following result: (1 + 0.2) / 1 = 1.2
Floor Space | 1 m2 | The value of the Width * the value of the Depth.
Volume | 1.2 m3 | The value of the Floor Space * the value of the Height.
Weight |  | The gross weight is the aggregated weight of the items contained in the child handling units and the aggregated weight of the external packaging items of the parent and the internal packaging items (of either type) of the child handling units. The net weight is the aggregated weight of the items contained in the child handling units.
