Message text: Min/max aggregation used in the update rules; cancellation not possible
Minimum / maximum aggregation is used in the update rules, which means
it is not possible to cancel this request (or not useful, as the
minimum/maximum aggregation is not removed when the data is updated
negatively, and, as a result, incorrect data would appear in the
InfoCube).
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Delete the request from the InfoCube.
If aggregates exist, it is not possible to delete the InfoCube. If this
is the case, deactivate the aggregate, delete the request from the
InfoCube, and reconstruct the aggregate.
If the request is compressed, it is no longer possible to delete it,
because the request ID is no longer available in the InfoCube, and the
system can no longer identify the data that you want to delete.
The only option is to delete the contents of the InfoCube completely,
and reconstruct the InfoCube from the PSA or the ALE inbound
processing, or to reload the data from the source system.
