Converting Stock Items to Variable-Size Items

Convert source components or assemblies, categorized as stock items, to variable-size items in the SAP S/4HANA system.

As the production engineer, sometimes you'll need to convert categorized stock items from the source to variable-size items in the target, and then maintain attributes such as size, formula, quantity, and unit of measure.

During synchronization, the converted item category is categorized as the variable-size item in the SAP S/4HANA system.

Prerequisites

You've planned components and assemblies in the Target panel.

For more information about planning and adding BOM items, see Planning and Publishing a Manufacturing Bill of Material (MBOM).

Procedure

In the Target panel, select the row that you want to convert to a variable-size item.
Choose  (More) → Convert to Variable-Size Item Category.

In the Convert to Variable-Size Item Category dialog box, enter the following details manually :

Details

Description

Size (1 to 3)

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.

Size Unit

This field describes the unit for sizes 1 to 3.

Formula Key

This key describes the algorithm for calculating the variable-size item quantity.

Note

You define the formulas in the Define Item Categories Customizing of the SAP S/4HANA system, which can be customized according to your requirements.

Example

Here are some examples of the standard formula keys delivered by SAP:

Formula Key	Formula Definition	Description
`F1`	ROMS1 * ROMS2	Area of rectangle
`F2`	ROMS1 * ROMS1 * PI	Area of a circle
`U1`	ROMS1 + ROMS2 + ROMS3	Perimeter of a triangle
`U2`	2 * ROMS1 + 2 * ROMS2	Perimeter of a rectangle
`V1`	ROMS1 * ROMS2 * ROMS3	Volume of a rectangular parallelepiped

Number of variable-size item

This field describes the number of pieces of the variable-size item that are required for the assembly.

Quantity of variable-size item

The system uses the sizes you enter and a variable-size item formula to calculate the quantity of the variable-size item.

Quantity Unit

This field describes the unit of measure for the quantity of a variable-size item.

For more information about maintaining the variable-size item, see Variable-Size Items.

Choose Convert.

Result: The selected component is converted to a variable-size item, and the icon is changed to  (Variable-size Component). When you publish the MBOM, the component is categorized as a variable-size item category in the SAP S/4HANA system.
