Since Siebel Analytics days repository developers
could achieve one level of nesting in Answers by adding a hyphen at the
beginning of a presentation table name, or by adding an arrow (->) at the
beginning of a presentation table description. This option offers only one
layer of nesting; it does not support multiple layers of nesting.
Starting from 11.1.1.6.2 an additional tab is included
called Child Presentation Tables tab in the Presentation Table dialog, which
would be used to give the appearance of nested folders in Answers and BI
Composer. This feature supports adding multiple layers of nesting, which is believe is a significant
improvement from the previous releases.
This blog is an attempt to mention the process of
nesting folders. In addition also include the method of convert presentation
folders utility to covert metadata to the new structure.
Nested Folder in Answers
An example of nested folder in Answers is as follows.
Presentation layer in the Administration Tool does not
display the nesting; the nesting only appears in Answers and BI Composer. Folders
only appear to be nested – they are not actually nested in terms of drill-down
Convert Presentation Folders Utility
As I mentioned, in previous releases of OBIEE,
repository developers would have included hyphen at the beginning of a
presentation table name, or put arrow (->) at the beginning of the
presentation table description to achieve one level of nesting. This method
will be removed in a future release.
Convert Presentation Folders utility is provided as
part of this release which can be used to convert metadata to the new structure
to support the presentation table nesting.
The steps used to convert presentation folders utility
are as follows
Administration
Tool >> Open Repository in Offline Mode >>Utilities >> Select
Convert Presentation Folders > Execute
After execution the hyphens and arrows will disappear
from presentation table names and descriptions, and the affected tables are
listed as child tables for the appropriate parent object.
