What causes this issue?

You attempted to maintain a conversion group for the material, but
other plants that have the same material only have an excise duty tax
group maintained for the material. Stock is already posted at one or
more of the plants.

System Response

The system removes the conversion group, because this situation is not
allowed after stock has been posted at one or more plants. The IS-Oil
data for all materials should be maintained uniformly for all the
plants.
