Planning notes / Whole-item loads
Measure pieces, not a guessed basket total
Quantities and unknown weights have different jobs.
The planner needs a dry weight per individual piece. A row with quantity three represents three pieces of that entered weight. It does not represent three shares of a combined basket weight.
A simple example
If three example towels each weigh 700 g, enter 700 g and quantity 3. The row contributes 2,100 g. If the pieces differ substantially, give them separate rows so the packing model can treat each whole piece accurately. All weights in the built-in example are fictional planning inputs.
Unknown is not zero
Leave the weight blank when you do not know it. A machine item with unknown weight stays in Needs review and is excluded from assigned load totals. Giving it a zero would hide that uncertainty, so zero is not accepted as a known piece weight.
Do not split a piece to make the arithmetic fit
A 4 kg piece assigned to a group with a 2 kg entered limit stays in review. The planner does not turn it into two loads. Reducing its quantity does not solve that one-piece mismatch. Recheck the item, grouping and appliance information rather than interpreting the result as a handling instruction.
Units stay explicit
Item entry accepts grams, kilograms or pounds and stores whole grams. Group limits are entered in kilograms. The display selector changes the results, not the meaning of those input fields.
