Engineering Change Management for Specifications

Use

This function enables you to make data changes for a particular key date using a change number. In this way, you can, for example, today enter data that will only be valid in the future. Each change number is valid from a particular validity date so that the data has a validity period in accordance with the change number.

If you make changes without using a change number, the standard validity period used goes from 01/01/0001 to 12/31/9999. The system enters the current date as the key date.
When you use a change number to change a data record for the first time, the SAP System divides the overall validity period into two adjoining validity periods. Whenever you use other change numbers that have different validity dates, the system further subdivides the validity periods.

See Example: Engineering Change Management

Note

The SAP System writes change documents irrespective of whether you use engineering change management or not.

For more information on the Engineering Change Management (LO-ECH) SAP component, see Help ® SAP library ® LO - Logistics ® LO - Logistics General ® LO - Engineering Change Management.

To use engineering change management for specifications, you must have set the Active indicator for the Substance object under Object types in the change master record you want to use. You do so from the initial screen of the SAP Systemby choosing Logistics ® Central functions ® Engineering change management.

Features

You can use engineering change management within specification management to:

Import value assignments
Create specifications

By choosing Extras ® Administration information on the specification management screens, you can find more information about, for example, the current validity period, the date of the last change, the name of the person who last changed the specification, the data origin, and the data provider.

You can work with or without engineering change management depending on your requirements. If you have used engineering change management to change the data of a data record, you must make sure that the right key date is entered when you call the data or enter the relevant change number.

Note

The change number has higher priority than the key date (see Example: Engineering Change Management).

The Change number, From date, and To date fields in the specification header data refer exclusively to the data of the specification header.
