Modification parameters are generally one-time settings for BOM management, which you should not change after you start using BOMs productively. In the standard system, default values are defined.

In this step, you define the following central settings for your BOM management system:

  • BOM validity maint.
  • Low date

When you create or process BOMs, the default date is the date defined in your system as the earliest processing date (01/01/1900 in the standard system).

  • BOM validity maintenance
If you activate validity date maintenance, you can specify a valid-from date when maintaining BOMs.
If validity date maintenance is not activated, bills of material are created as of the current date or the system low date (1/1/1990).
  • EC management active
If you activate engineering change management, you can make historical changes to BOMs with reference to a changenumber. (This means that the status of the BOM both before and after the change is stored in the system.)
In this step, you only specify whether engineering change management can be used for maintaining bills of material. In step Configure history requirement for BOMs, you define whether you want to make the use of engineering change management a requirement in certain cases.
  • Hist. reqmt variant
Use this indicator to control when history requirement applies to new variants or alternatives in a BOM group.
  • Sub-item document
You use the Sub-item documentation indicator to define whether changes to sub-items are documented.

Technical type

  • Mult. BOM inactive
You can define that no further alternatives can be maintained for multiple BOMs.
  • Variant BOM inactive
You can define that no further variants can be maintained for variant BOMs.

Bill of material item

  • BOM item explosion type
If you create a BOM item with reference to a change number and change the valid-from date (in the change header or alternative date), then this can change the sequence of validity periods of a BOM item.
The indicator BOM item explosion type specifies whether and according to what rules, the system determines a unique change status, when you display, evaluate or change a BOM to a date in the overlap period.
SAP supports the BOM item explosion type 2 (version with latest valid-from date) for SAP S/4HANA, on-premise edition. To make this Customizing setting, open the Define Modification Parameters activity in Edit mode, choose BOM item explosion type 2 and Save. The BOM explosion type is updated.
  • Description variable-sized item
This indicator controls which text is displayed in BOM processing for a variable-sized item.
  • Repeated effectivity via external item ID
This indicator ensures that an item that already exists under an external item ID can be used.

General settings

  • Unit 'piece'
In the standard system, this field contains a unit of measure for "piece". You can change this unit. This unit is the base unit of measure (BOM header) or the component unit of measure.
Base unit of measure for:
  • Equipment BOM

  • Functional location BOM

  • Document structure

  • Standard BOM

Component unit of measure for:
  • Text item

  • Document item

  • Non-stock item without material master record

  • CAD active
If you want to maintain BOMs from a CAD system, set this indicator. This activates an additional field in the BOM header and BOM item, which tells you whether the BOM header or BOM item was maintained from a CAD system.

If you deactivate engineering change management, changes to bills of material are not recorded.

The modification parameters defined here apply to all BOM categories.

The following settings are made in the standard R/3 System:

  • Validity date maintenance and engineering change management are active.
  • The current system date is the default valid-from date.
  • CAD is active.
  • Explosion type for BOM item: blank (no additional interpretation)

Use the standard default settings.

Define the central defaults for your BOM maintenance system.
