You buy it once — a 0.75 L bottle of wine — but you sell it in two ways: the whole bottle and the 150 ml glass. It is solved with a single goods receipt (NIR) line on which you fill in TWO columns, and with two sale products that take the same raw material in their recipe, with different quantities. You do not need a second NIR, a second line, a sub-recipe or a production. The same answer applies to draught beer, whisky by the glass, syrup by the shot or oil by the portion.
The steps, exactly in this order
Open the supplier invoice from the Costs menu (downloaded from S.P.V. or entered manually) and press the NIR button. The detailed steps are in the article "Create Reception Entry Note".
On the wine line, in the "Goods receipt" column, select or create the goods item on the spot, with MU = L and Unit quantity = 0.75 — how much one bottle contains.
On the SAME line, also fill in the "Raw material receipt" column — this is the key step, and the one most often missed. Create or select there the raw material with the same name, also in L. When you save the NIR, the same reception brings into the account both the goods item (for the purchase record) and the raw material (for recipes).
In Nomenclature - Products, create the two sale products. Both are of type "Contains recipe" and both take the RAW MATERIAL in their recipe, with different quantities:
the product for the whole bottle - quantity 0.75 L in the recipe
the product for the glass - quantity 0.15 L in the recipe
That is all: one bottle sold deducts 0.75 L, one glass deducts 0.15 L, from the same stock.
Why both products are built on the raw material
The recipe of a product of type "Contains recipe" accepts only raw materials, never goods — the search in "Product recipe" does not even offer goods items.
And on a NIR line with both columns filled, the stock movement is recorded against the RAW MATERIAL. The goods item remains the link to the purchase — it appears on the NIR, on the invoice and in the purchase history — but it gets no balance of its own on that line.
What this means in practice: the whole bottle must NOT be sold with a product of type "I sell it as I buy it" over the goods item. That product would deduct an item the reception never fed, so it would go negative. Both the bottle and the glass are sold from the raw material, only with different quantities in the recipe.
Details that matter once the steps are done
Keep the goods item and the raw material on the same unit of measure. If the raw material is in ML, the same reception enters as 750 ML — that is correct, but then the recipes must be written in ML too: 750 for the bottle and 150 for the glass.
The goods item's name can fill in the fields for you. If the goods item is called "White wine 0.75 L", the application automatically sets MU = L and Unit quantity = 0.75 — exactly what you want here, so there is nothing to fix. The rule does not apply to raw materials: a raw material can have any unit of measure, whatever its name. Details are in the article "Unit quantity on a goods item".
The VAT rate is taken over automatically from the goods item. A raw material's form has no VAT field.
It is correct and normal for the goods item and the raw material to have the same name. They are not a duplicate — do not merge them and do not delete either one.
The "Raw material receipt" column only becomes editable after you have filled in the "Goods receipt" column on the same line. Until then the cell shows N/A.
What not to do
Do not choose between "Goods" and "Raw material" — you need both items, on the same NIR line.
Do not leave the "Raw material receipt" column empty. Without it the wine enters stock as goods, but it cannot be put in any product's recipe and is not deducted on sale.
Do not create a second NIR line, a second NIR or a "separate reception for the glasses". There is one invoice line and one reception — the glass is a quantity in a recipe, not a document.
Do not use a sub-recipe or a production. Nothing is transformed, it is poured from the same bottle.
If you sell only the whole bottle
Then you need none of the above: leave the goods item on MU = PC and Unit quantity = 1, do not fill in the "Raw material receipt" column, and the product can be of type "I sell it as I buy it", linked directly to the goods item. Make sure the goods item's name no longer contains the volume, otherwise the application rejects PC.
