Suppressing writing to the Changelog
For systems that write the Changelog to a relational database, it can be beneficial that
      the imports executed by this system are not logged again in the Changelog. This is better for
      the performance and for easier processing.
    To facilitate this, the AleaLog attribute in the <Alea:CellBatch> XML element can be used:
<Alea:CellBatch AleaLog="false">
    This attribute is optional. The default value of this attribute is true. If set to false, the imported values are not logged to the Changelog.
The Administer OLAP Database permission is required for this attribute. If a request with
        AleaLog="false" is issued without this permission, no data
      is imported and this error message is returned:
You are not authorized to carry out this operation
