On the Variable-Size Item Data screen, you maintain data that is specific to variable-size items.

If you enter variable-size item data, the system calculates the quantity. All calculations in BOMs are based on the international system of units.

This is the data you can maintain specifically for variable-size items:

These three fields contain the dimensions of the variable-size item. The system uses these dimensions as variables in the selected formula to calculate the variable-size item quantity.

This field describes the unit for sizes 1 to 3.

If you do not enter a unit for variable-size item sizes 1 to 3, the system uses the default unit of measure that you defined when you configured your system.

The dimension of the size unit and the dimension of the unit of the variable-size item quantity are related (see the example below).

Example

The following table contains the variable-size item data used to calculate the quantity for a sheet of metal.

Variable-Size Item Data for a Sheet of Metal

Size

Dimension

Entry

Size unit

1

Length

200

MM

2

Width

300

MM

If you do not enter a formula, the system calculates the quantity for the variable-size item according to the standard formula:

Size 1 * Size 2

The result has the dimension area:

200 MM * 300 MM = 60,000 MM2 (square millimeters)

The variable-size item unit must have the dimension area (MM2, CM2, or M2) or you must maintain conversion factors in the material master record.

This key represents the algorithm for calculating the variable-size item quantity.
In Customizing for Production, you can define formulas by choosing Bill of Material
® Item Data ® Define formulas for variable-size items. You can also use the formulas defined in the standard R/3 System.

You can enter units of measure for calculating the variable-size item quantity with a formula. The calculation always uses unit for the dimension from the international system of units (for example, M3 for a volume in cubic meters). These units are defined in Customizing (dimensions for units of measurement).

This entry is the number of pieces of the variable-size item required for the assembly. This entry is used for calculating raw material requirements.
The unit
PC (piece) is defined as a default in the standard R/3 System, in Customizing for Production, under Bill of Material ® Control Data for Bills of Material ® Define modification parameters.

The system uses the sizes you enter and a variable-size item formula to calculate the quantity of the variable-size item.
If you do not enter a formula, the variable-size item quantity is either the product of sizes 1 and 2 (for dimension area) or the product of sizes 1, 2, and 3 (for dimension volume).

The variable-size item quantity is used for calculating raw material requirements:


Raw material requirement =

Number of variable-size items * Variable-size item quantity * Required quantity
------------------------------------------------ ----------------------------------------------------------
Base quantity
