You can only change the revision level assigned to a material from the engineering change management menu.
How to change a revision level for a material:
- Choose Revision level → Material revision level → Change.
- You see the initial screen. You can enter the material (BOM header material) for which you want to change one or more revision levels on this screen.
Confirm your entry.
- You see an overview of all the revision levels assigned to the material so far, sorted by revision level.
You also see the following data:
– Valid-from data
– Change number
– Description of change number
You can sort the entries according to various criteria, for example, by date or change number.
- Change one or more revision levels. To do this, overwrite the RevLev (revision level) field.

You can display possible entries for the sequence of revision levels defined for a material.
The system checks whether the new revision level you entered has already been assigned to a change with reference to another change number. If it has, you see an error message.
- Save the changed revision levels.
