This field can be filled in only if the Purchase field contains a quantity to be obtained from purchasing. If the Purchase field is set to '0', the supplier is not applicable.

If you enter a supplier in this field, this supplier will appear on the purchase requirement for the part. If necessary, the supplier can still be changed on the purchase requirement.

If the parts have a 'Purchase' origin, this field shows the order code that determines how the parts are purchased:

To order, custom:	The parts are purchased according to the exact specifications entered on the sales line (quantity, length, width, height).
To order, commercial quantity:	The parts are purchased according to the purchase unit specified for the part in the Parts module (Purchase tab, Purchase unit field). The order quantity will be the number of purchase units required to meet the requirement.

Use this field to specify how the supplier is to supply the part to you, for example 'Painted' or 'Blasted'. The rate you have specified for the conservation is included in the cost price of the production part.

This field shows whether the part is a long lead-time item.

Select this check box if you want to request a purchase offer for the selected part. You can request the purchase offer only after the calculation line has been authorized.

This field shows the quantity that was specified on the purchase offer. This is an informational field that cannot be modified.

If this calculation line is part of the calculation of a phantom part (a semi-finished product for which the product calculation is copied to the calculation), this field shows the line on which the phantom part has been included. This enables you to see which calculation lines are part of a phantom part.

This is the waste percentage taken into consideration in the calculation. The waste percentage is taken into account in the calculation of the quantity, the weight, and the surface (General tab), and in the variable costs.

These fields are informational fields that could be used, for example, by the planner. The planner could use them to register the exact quantities and sizes as specified on the drawing.

If you take the part from stock, enter the warehouse location from which it must be deducted.

This setting determines how parts from stock are used.

FIFO:	Parts that are recorded in stock first are to be issued first.
Random:	Parts can be issued in a random order.
Floor stock:	You can use this setting to select parts that qualify for backflushing. If parts with this setting are used in production, the preliminary production quantity can be deducted from the stock automatically. Alternatively, you can configure the software to not automatically deduct parts with this setting, but only parts that are not floor stock.
Do not maintain stock:	This setting is automatically used for parts of the 'Costs', 'Services', or 'Functional BOM' type. These parts are not kept in stock and they do not have to appear on documents such as purchase requirements. It is not possible to use the setting for the part types 'Purchase part' and 'Production part'.

This is an informational field that cannot be modified. The values are retrieved from the Issue sequence field for the part on the Logistics tab in the Parts module.

For floor stock you want to record using the automatic backflushing process, specify the warehouse location from which the floor stock needs to be deducted.

If this check box is selected, the component will be delivered to the customer. This is relevant, for instance, for components of a machine that will be assembled at the customer's site. You can also use it for additional parts that need to be included in the delivery, such as installation items for a machine.

This field is available only if the part will be delivered to a customer ('Delivery to customer'). The field value indicates the documents the part line is to be printed on.

If this check box is selected, the part on the calculation line is a special BOM part. Parts marked with this field can all be printed on one report.

This check box is selected if the current part line was created in the actual costing stage and was therefore not calculated in the preliminary costing phase. In this case, the line relates to a part that was used in the production file, even though this had not been planned.
