OBIEE-11g Double columns question

Question

Hi guys, on my pc i've installed business intelligence suite 11.1.3 and now I need support about double columns feature. In the business model I've this hierarchy
Region -> Province -> Municipality
where the keys for each level are represented by the name of the element, the problem is that this keys are used to map geometric shapes to enable the map views features and the Municipality values are ambiguous in their domain (could exist two municipality with the same name but different province) in the official documentation is wrote that to unique identify a shape should be used a double columns field but when I 'apply the double field feature to the hierarchy levels the drill feature doesn't work properly and I get a strange filter error (seems that the system filter the value by id on the wrong field). Somebody could help me to understand if I can define a hierarchy where the keys have a descriptor id associated ?
Thanks a lot Regards

Answer 1

I 've also come up with the same issue. I am using OBIEE 11G (11.1.1.5.0) and Oracle Mapviewer Ver11_1_1_4_B110225.
On the RPD, My hierarchy is defined as: District -> Quarter -> Neighbourhood.
For each hierarchy level I am using:
District Logical Level keys:
District Id: Primary Key
District Name: Use for Display
Quarter Logical Level Keys:
Quarter Id: Primary Key
Quarter Name: Use for Display
Neighbourhood Logical Level Keys:
Neighbourhood Id: Primary Key
Neighbourhood Name: Use for Display
I need to associate each Mapviewer theme's ID (District ID, Quarter ID, Neighbourhood ID) with a relevant BI column, because the theme names are not distinct.
I have set the double column (Descriptor Id) feature: (District ID, Quarter ID, Neighbourhood ID) on each BI name column (BI Distict Name, BI Quarter Name, BI
Neighbourhood Name) of the business model and associated the layer key (ID) of each Mapviewer theme with the corresponding BI name column.
On the map view, drilling down from District to Quarter works properly, but I get the following action error while drilling down from quarter to neighbourhood:
An error occurred while trying to generate drill down query.
Odbc driver returned an error (SQLExecDirectW).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError:

SQL Issued: {CALL NQSGenerateDrillDownQuery('SELECT District Name saw_0, Quarter Name saw_1, DESCRIPTOR_IDOF(District Name) saw_2, DESCRIPTOR_IDOF(Quarter Name)
saw_3 FROM "Subject Area" WHERE DESCRIPTOR_IDOF(District) = 5','1','''5'',''31'',31','-1 -1 -1 -1 -1','0,2,3')}
However, if I add a table view on my analysis and click on the table view's quarter link, drilling down works ok both for the table and for the map view.
Moreover, I tried removing the double column (descriptor Id) feature from the business model while maintaining the hierarchy as described above.
I then associated the layer key (ID) of each Mapviewer theme with the corresponding BI ID column instead of the BI name column.
On the map view while drilling down from District to Quarter, a filter to a specific District is applied, but the associated Quarters theme is not displayed.
Finally, if I enable the "Use for Display" checkbox for each hierarchy level's primary key on the RPD, and maintain the association between the layer key (ID) of
each Mapviewer theme with the corresponding BI ID column, drilling down works correctly but only on the ID.
I need drilling down to work while clicking on the each name BI column of the hierarchy while defining the association on the layer key ID of each mapviewer
theme. Is this possible? Any ideas?
