No values available for revision level

What causes this issue?

You want to assign a revision level to a change made with reference to
a change number.

System Response

Using settings in Customizing, the system determines the next available
revision level within the defined sequence.
You see this message in one of the following situations:
No sequence has been defined for the revision levels for the material
or document.
The changes to the chosen material or document have already been
labelled with all the predefined revision levels.

How to fix this error?

You cannot set a revision level for a change to a material or document
until the revision level sequence has been created or extended.
You maintain revision levels as follows:
<DS:SIMG.SIMG_CFMENUOLPSOS55>Define revision level for material</>
<DS:SIMG.SIMG_CFMENUOLPSOS57>Define revision level for document</>
