This error occurs when MDL syntax requires an object and is unable to find it. In
this case, the object is a level.
The problem may be that the level was not referenced, or that it was referenced
with an incorrect object name or object identifier.
Procedure
You can verify Cognos Transformer object names and identifiers on the Windows
interface. To make them visible, select the Object name and Object identifier
check boxes on the Titles tab of the Preferences property sheet. The object name
and identifier will appear in the title bar at the top of each property sheet, and also
in a tool tip when your pointer hovers over an object.
You can also find object identifiers in the .mdl file. For more information, see the
Cognos Transformer Developer Guide.
TR2308
A date function has been chosen but the dimension is not a time dimension.
This message appears when date functions are set for a dimension that is not a
time dimension.
Procedure
1. To specify that the dimension is a time dimension on the Windows interface,
2. Alternatively, remove the date functions entirely.
TR2312
You made level level_name into a convergence level that connects two or more
alternate drill-down paths. Categories in convergence levels must have unique
source values. Can there be two categories in this level with the same source
value?
You have created a convergence level but have not designated it as unique.
Uniqueness is set by selecting the Unique check box on the Source tab of the
Level property sheet. Or in MDL, it is set by the option UniqueCategories True in
the Level definition statement.
Procedure
1. If you select No in answer to the message prompt, the setting is changed to
2. If you select Yes, the convergence level is not created.
set the dimension type on the General tab of the Dimension property sheet to
Time. In MDL, include the option DimType Date in the Dimension definition
statement.
Note: On the Windows interface, you may need to temporarily select the Time
dimension type on the General tab of the Dimension property sheet so you
can open the Time tab and delete the appropriate date function(s).
Unique and the required convergence level is automatically created.
