 Assigning a Revision Level to a Material 
Use

You can assign a revision level to a material either from an engineering change management function or while you are processing a material master record or BOM for the material.
This section explains how to change the revision level from engineering change management functions.
Prerequisites You can only assign a revision level to a material that has a material master record.

• If you create a material with Create ® Immediately, the system creates a material master record immediately. In this case, the revision level can also be allocated immediately.

• If you create a material with Create ® Schedule, the system first creates a document (and no material master record). In this case, the revision level cannot be assigned yet. The material master record is not created until you activate the scheduled material, and then a revision level can also be assigned.

Procedure From the Engineering Change Management menu, choose the Revision level option. The following options are available: create, change, and display material revision level.
To create a revision level for a material:

1. Choose Logistics ® Central functions ® Engineering Change Management ® Revision Level ® Create.

You see the Create Revision Level: Initial Screen.

2. Enter the material that you want to assign a revision level to and select .

You see the Create Revision Level: Detail.

3. Enter the change number that you want to assign a revision level to.

4. The possible entries in the Revision level field depend on your company-specific settings (Customizing for Engineering change management under Set up control data).

• If internal number assignment is defined for revision levels, do not make an entry in the Revision level field. Confirm your entry. The system assigns the next available revision level from the defined number sequence. You can overwrite this default value with another value. However, the revision level you enter must be defined in the sequence and must not have been assigned to the material so far.
• If external number assignment is defined for revision levels, the system still assigns the next available revision level from the defined number sequence. You can overwrite this default value with another value. However, the revision level you enter need not be defined in the sequence.

You can define the settings in Customizing such that a higher revision level must be assigned for both external and internal number assignment. A message appears telling you which revision level has been assigned to the material.

4. Save the revision level for your material.

When assigning the revision level from the processing functions for the material master or the bill of material, you find the functions for maintaining the revision level under the menu option Extras.
