OLAP Designer: Error occuring while sending MDX query

+1 vote
1 view

I created the following simple Mondrian file, uploaded correctly as Mondrian schemas catalog:

<?xml version="1.0"?>

<Schema name="Movies DWH">

  <Dimension name="Sale Channels">

    <Hierarchy hasAll="true" allMemberName="All Channels" primaryKey="key">

      <Table name="sale_channel" />

      <Level name="Channel type" column="channel_type" uniqueMembers="false" />

      <Level name="Channel" column="channel_id" uniqueMembers="false" />

    </Hierarchy>

  </Dimension>

  <Cube name="Tickets Sales">

    <Table name="sale" />

    <DimensionUsage source="Sale Channels" name="Sale Channels" foreignKey="sale_channel_key" />

    <Measure name="Quantity" column="quantity" aggregator="sum" />

  </Cube>

</Schema>

When I tried to build a template for an OLAP document using the OLAP designer, I obtained an error after pressing START button (on the right corner of the Web page). I checked this log file knowageWhatIfEngine.log reporting an error related to the serialization of the pivot table. Also inspecting the call with the browser I found the following error into the response:   

{"errors":[{"localizedMessage":"Error serializing the emberEntry","message":"com.fasterxml.jackson.databind.JsonMappingException: Error serializing the pivot table","errorService":""}]} 

How is it possible to solve this problem?

Ok . This is a bug and in the new version is going to be fixed . You are missing a file that contains formulas definitions for calculated fields . The fastest workaround is to put an empty file with name formulas.xml inside your server resource folder on the following path

{tenant name}/Olap/formulas.xml
