Data type of the base attribute or the base value does not match...

Question

...the assigned expression.
Hello all,
I always get the Error
+<ERROR+
TEXT="'DWH.CUB_REGISTRATIONS_AW.REGISTRATIONS': XOQ-02517: Der Datentyp des Basisattributs oder der Basisgröße stimmt nicht mit dem zugeordneten Ausdruck überein.
XOQ-01400: Ungültige Metadatenobjekte"/>
The English message must be something like this:
The data type of the base attribute or the base value does not match the assigned expression.
when I run my mapping. The attribute REGISTRATIONS is NUMERIC (12,2) in the Cube and I map a NUMERIC(12,2) constant in it.
I use a simple OWB-Mapping for loading, but I don't understand why it doesn't function. Other mappings where the attributes are out of a
table I put in a cube are running well.
I tried different things, but nothing fixed my problem. Any idea ?
Thanks a lot for help
Michael

Technically this is a 'warning' from the server, not an 'error'. This means that the change you made should have been submitted, but you get an warning message on the client. AWM would suppress this warning, but evidently OWB does not. Can you switch to use AWM?
Here is the definition of the warning along with 'cause' and 'action' sections. (Unfortunately these sections are not translated into German for some reason.)

02517, 0, "The data type \"%(1)s\" of the base attribute or base measure is different from the mapped expression \"%(2)s\"."
// *Cause: Either the base attribute or base measure with the mapped expression was set to an inconsistent data type, or it was mapped to an expression of a different data type from its fixed data type.
// *Action: When changing a mapped expression for a base attribute or base measure, ensure that the expression has the same data type; otherwise, set the data type of the base attribute or base measure to NULL first. When a base attribute or a base measure has an existing mapped expression, do not set it to a different data type.

It is probably safe to ignore this warning, but if you can post the relevant XML for the cube, then will probably be able to spot the problem. I assume that REGISTRATIONS is a measure in the cube CUB_REGISTRATIONS_AW, so this is what you can look for in the XML:
(1) The definition of the base measure along with the datatype. It should be something like this
<Measure>
  <BaseMeasure
    SQLDataType="NUMBER(12,2)"
    ETMeasureColumnName="REGISTRATIONS"
    Name="REGISTRATIONS">(2) The mapping info for the measure, which should looks something like this:
<MeasureMap
  Name="REGISTRATIONS"
  Expression="...">
  <Measure Name="REGISTRATIONS"/>
</MeasureMap>I don't know if you can get the XML directly from OWB. If not, then DBMS_CUBE.EXPORT_XML should work (assuming you are in 11.2). You could also attach AWM and save the cube to an XML template.
