Hi Shailesh,

Pls find below the excerpts from SAP's help:

You can change the data contained in a material master record in one of the following ways:

Immediately

By scheduling the change

In both cases, you can make your changes with reference to a change number. This identifies a change master record in engineering change management and has the advantage that changes to different objects (such as the material, bill of material, or routing) can be grouped together under this number. If, for example, a particular product gives rise to a complaint, you can record any resulting changes to the relevant objects under this number. For more information, see Special Features for Materials in the SAP library documentation Engineering Change Management (LO-ECH).

Any changes that you make to material master records are recorded in change documents. In the case of scheduled changes, the change is stored in the change document and not in the material master record itself. The date at which the change is to take effect is stored in the document header. Such changes have to be activated.

Changing a Material with Reference to a Change Number

Changes to a material are stored in a change document rather than being saved in the material master record itself. The valid-from date is stored in the change document header.

Changes to the material master record with reference to a change number are made independently of the function.

Hi

Change Number

Number used to uniquely identify a change master record.

Use

If you make a change with reference to a change number, or create an

object with a change number, the following functions are at your disposal:

The system determines the effectivity parameters

The conditions that the change is effective under can be defined in the change master record as follows:

Changes with a date effectivity (valid from date)

Changes with parameter effectivity (for example: serial no. effectivity)

Log of the changes made

Documentation for the changes

Revision level to indicate the change status of a material or document

Changes released for the different areas in the company

Definition: change master record

Engineering Change Management (LO-ECH)

The data that contains all information required for managing a change.

The master record contains descriptive data, such as the reason for the change, and data with control functions, such as valid-from date and indicators for object types. In addition to this data, which can be updated directly, there is data that the system updates automatically, such as administrative data.
