Invalid aggregation level

What causes this issue?

If a release from DP to SNP takes place within a mass processing job,
the characteristic that represents the product in the InfoCube is
selected as the aggregation level. If the InfoCube also contains a
characteristic that represents the location (that means that location
split is not used) this must also be chosen as the aggregation level.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

- In Batch Planning Maintenance: Adjust the aggregation level
- In Activity Maintenance: Adjust the activity
