Stock checks and material shortages

On a draft or planned production order, the Check stock button in the Stock Shortage panel shows whether the source warehouse has enough materials. The Start Production window lists the required, available and missing quantity per material and, where possible, suggests a substitute or a sub-recipe.

The system multiplies the recipe's material quantities by the batch multiplier and compares them with the stock in the source warehouse (or the target warehouse if there is no source warehouse). Quantities reserved for something else do not count as available. Services are not checked, because they are not taken from stock.

If something is short, the panel shows the number of shortages and offers two options:

• Resolve Shortages – create purchase or production orders for the missing materials.
• Recheck – for example after a delivery has arrived.

The Start Production window also runs the check when it opens and lists the missing materials in a table:

• if a substitute with enough stock exists for a material, you can pick it with the Use … button;
• if the missing material is produced by another active recipe, the Sub-recipe button lets you create a production order for it (the button also shows the suggested multiplier).

Production cannot start with missing materials: the stock on hand, or the chosen substitute, must cover the requirement.
