k. How to limit the total stack layers when different cargo specs stack on each other
When multiple cargo types may stack on each other, the total number of stacked layers may need to be limited. How is this defined?
Example:
Loading data:
| Name | Qty | Length (cm) | Width (cm) | Height (cm) | Weight (kg) |
|---|---|---|---|---|---|
| A | 6 | 110 | 110 | 112 | 150 |
| B | 28 | 110 | 105 | 40 | 80 |
| C | 26 | 110 | 105 | 45 | 76 |
| D | 28 | 110 | 105 | 35 | 91 |
| E | 26 | 105 | 100 | 20 | 30 |
Loading requirements:
1) Height perpendicular to the ground only.
2) B, C, D may stack on each other but the total layers must not exceed 4.
3) A is heavy — place at the bottom. E is light — place at the top.
4) Compute the best container and how many.
Choose Container loading / Multi-SKU.

Step 1: Cargo → Excel batch import.
1) Get template.

2) Fill template:
① Name, qty, dimensions, weight.
② Allow only stand and stand horizontal rotation.

③ Set max stack layers for B, C, D under stand/stand horizontal rotation to 4, and give B, C, D the same stack code. Stack codes can be numbers, letters or characters (here "BCD").

Set load-bearing levels: A = 12 (heavy at bottom), E = 9 (light on top). Defaults are 10; B, C, D may be left blank or set to 11.

3) Import from Excel.

Step 2: Container → Add from database → 20GP, 40GP, 40HC. Corner castings 10×10×10 cm and reserved sizes.

Step 3: Loading rules → set Max stack layers calculation to "Treat cargo with the same stack code as one type for stacking".

Click Auto-calculate. The batch fits in one 40GP. The 3D view shows A at the bottom, E on top, and B/C/D never exceed 4 layers total — meeting requirements.
