OBIEE rpd formula help

Question

Hi All
My problem is mainly relating to the usage of operators and functions in the OBIEE repository...
I need to extract the file name from a given path... (this is basically for Usage Tracking purposes)
The path can be of 4 types:
1) /users/[email protected]/Charts Reports/Report\/test.) -- file Report\/test.
2) /shared/project/Reports \/ Charts/test \/ Report -- file test \/ Report
3) /shared/project/Reports \/ Charts/test Report -- file test Report
4) /shared/project/Reports/Report 1 -- file Report 1
The '\/' that you see happens, when you save a report/folder in Answers with a '/' in the name (it converts it to '\/' supposedly).
I am not able to write a formula for a logical column that can extract the file name given these 4 types of input paths.
I have a written a SQl query that does all this perfectly fine but am having a tough time converting this to the OBIEE formula. So I guess
I'll have to start off separately on the rpd formula.
I tried the following formula but it does not work for type 1) and 2) ... It works for types 3 and 4. Though I dont find anything wrong with
this formula, I think the CASE operator might be a problem.
CASE WHEN LOCATE ('\/',:PATH) > 0
THEN CASE WHEN LOCATE ( '\/',SUBSTRING(:PATH FROM LOCATE ('/', SUBSTRING (:PATH FROM 1 FOR LOCATE ('\/',:PATH,-1) ) ,-1 ) + 1 ) ) > 0
THEN SUBSTRING (:PATH FROM LOCATE ( '/',:PATH,-1)+1 )
ELSE SUBSTRING(:PATH FROM LOCATE ('/', SUBSTRING (:PATH FROM 1 FOR LOCATE ('\/',:PATH,-1) ) ,-1 ) + 1 )
END
ELSE
SUBSTRING(:PATH FROM LOCATE ( '/',:PATH,-1) +1 )
END
Can someone help me write a better formula to perform this function
Thanks a lot

Answer 1

Hi All
If this helps... When I said it does not work for the input types 1 and 2 (above post), this is the result that I get in Answers when I use my formula...
Input 1) /users/[email protected]/Charts Reports/Report\/test.) Result: test.) Expected Result: Report\/test.)
Input 2) /shared/project/Reports \/ Charts/test \/ Report Result: Report Expected Result: test \/ Report
Thanks a lot...
