Before You Create New Items

Before you can enter a BOM item, certain requirements must be met.

Entering Material Components

Before you can enter material components, the following requirements must be met:

A material master record exists in the system.
This does not apply to non-stock items without reference to a material master record, or to intra materials.
If you create a material BOM with reference to a specific plant, all the material components of the BOM have plant data for the selected plant.

Note

If the BOM is for plant maintenance purposes only, the system does not check for plant data, so you can create a BOM for a material with reference to a plant, even if no plant data is maintained for the material.

The material type of the item is allowed in combination with the material type of the BOM header and the usage.
In the material master record, you can maintain alternative units of measure to the base unit of measure.
In BOMs, only the base unit of measure and the unit of issue are used.

Note

If you do not enter a unit for an item with a material master record, the system enters a unit from the material master record:
If a unit of issue is entered on the Work scheduling 1 screen or the Storage screen, the system uses this unit. Otherwise, the system uses the base unit of measure.
For non-stock items without a material master record, the system proposes the component unit of measure PC (piece).

If you enter a cost element for a non-stock item, you must enter a G/L account that has been defined for the company code.

See Item Categories for Material Items.

Entering Document Items

Before you can enter document items, the document must have a document info record. The document must not be marked for deletion.

See Document Item.

Entering Class Items

Before you can enter a class item, the class must exist in the system. For a configurable BOM, the class type must be defined for configurable objects (for example, 200 – configurable materials, 201 – configurable documents).

See Class Item.

In the additional data of class maintenance functions, there are several fields that control the use of the class in BOMs.

The Allowed in BOMs indicator must be set before you can enter a class as a class item.

Other additional data is also copied from class maintenance functions as default values. You can change this data for each BOM individually.

See Class Data.

The unit of measure entered in the additional data of the class maintenance function cannot be changed in the BOM. However, you can enter a unit with the same dimension.

Example

You enter the unit of measure meter (dimension length) in class maintenance. When you enter the class as a class item in a BOM, you can also enter the units of measure millimeter or centimeter (also dimension length) in the BOM item.
