Snapshot in Discoverer

Hi,
I have two Dimensions in the fact, these are Dim_Quarter and Dim_Region. Dim_Quarter has two levels i.e. Year and Quarter with Hierarchy Year --> Quarter, and Dim_Region follows the Hierarchy Region --> State -> District.
Now I want the Snapshot functionality for measures when we Roll Up from Quarter to Year i.e when we roll up from Quarter to Year, i need to display the value of Quarter four(Q4) against the measure not the aggregated value as done by default in discoverer.
Can anyone please tell me how to proceed on this.
Any Help is appreciable.
Thanks and Regards
Mukesh Harjai.

Hi All,
Can anybody help me out in solving this problem. I need that the value against Quarter four(Q4) should be displayed for a measure when i roll up from Quarter to Year. Discoverer Sum up values for all quarters when we roll up.
Please Help
Thanks and Regars

Snapshot too old ORA-01555 from select statement (discoverer)??

Hi All
Am I loosing the plot .. but we have a select statement run from discoverer which is causing the famous snapshot too old error.
My understanding is that undo is generated from select/insert/update.
So why is the following discoverer Select statement causing the error?
from alert
ORA-01555 caused by SQL statement below (SQL ID: gk0wxgqmx66sh, Query Duration=3866 sec, SCN: 0x001e.089cf3f9):

The SELECT statement is the victim.
Some session is doing DML against the same table against which the SELECT occurs & is likely doing COMMIT inside a LOOP.

Datawarehousing within Discoverer - Storing snapshots

I'm in the process of constructing a datawarehouse using discoverer.
I need to produce a full set of reports on the data at the end of every month.
I want to keep a full record of what I report every month.
Initially I thought I might be able to archive PDFs or use Scheduled reports.
Each month I will produce a report which includes costs of year to date and a forecast until the end of the year. Once I have made a number of forecasts, I want to compare them with each other and explain exactly why the forecast has changed.
PDF's or Scheduled Reports won't do this because they just store the report but not the underlying data in a form which can further be analysed.
Effectively I want each month to store a snapshot of the whole years data for future reference.
Then as snapshots build up I want to be able to compare snapshots or even show a trend of the results of a snapshot over time. (e.g. a trend of the forecast as well as a trend of expenditure)
Maybe the details of my finances are not of too much importance. What I need is decide the best way to implement a method for storing the whole data situation once a month in such a way that I can reconstuct old reports AND compare old reports.
I wondered about OLAP but am unable to get the license for that.
I also wondered about Materialised views which certainly take a snapshot but as far as I can see when the view is refreshed I lose all the data from the last snapshot.
I'm coming to the conclusion that I need to manually set up a facttable and a number of dimension tables. Then each time I want to create a snapshot, I would copy all the required data from my data staging area, into the fact & dimension tables and include a dimension called "snapshot" which records when I did the snapshot and give it a name (such as "Jun 07"). Then I can keep a record of all snapshots in one model and can report from it AND copare old reports or even show a trend of reports over time.
It's possible I'm missing a feature of DIscoverer that would help?
If anyone knows of anything which would help I'd appreciate you letting me know.
Even if it's to confirm that my proposed approach sounds like the best one.
Kind regards
Suhada

Discoverer is a reporting tool, not one for building a warehouse. The design and implementation of a data warehouse is not the same as the reports that come out of it.
That said, how to solve your problem...
You could use materialized views to store the data monthly, but I think that would be a bit of overkill. One possible solution would be to store all of your data in your fact tables, then create a report in Discoverer that accepts a date as a parameter. The report would calculate/aggregate the data up to that date (from the start of the year), and provide a forecast. The report could then be scheduled to run monthly. If users wanted to see a previous month, they would change the date parameter and rerun the report.
Another problem with the materialized view approach would be late data entry. Suppose there is a scheduled job that creates the MV at midnight on the 1st day of the month. The MV gets created, then the next morning, and employee comes in and finds invoices, orders, or other data that needed to be posted for the previous month. The data could get entered, but the MV is not refreshed, and now the data in the MV is incomplete.

How to run discoverer 3i viewer on a replicated snapshot site ?

hi,
we are using oracle discoverer viewer on a replicated snapshot site ,in discoverer viewer edition we query the reports made in oracle user edition.In discoverer user edition first we save the report in the database in the table DIS_DOCS_ in EUL.now when we try to replicate this table ,we found that the LONG RAW type column in this table cannot be replcated. Now if we create a snapshot of this table without this LONG RAW type column it gets replicated. Now if i run this report on discoverer 3i viewer through my replicated snapshot site, I got a error message ORA-00904 Invalid coloumn name . and report does not work. can any body help me in how to run the report on discoverer 3i viewer using a replicated snapshot site for the table DIS_DOCS_ (this table is created when u create the EUL in the Administration Edition of the Discoverer

IIS MP - Enabling Rules and Discoveries that are Disabled by Default

Dears,
In the IIS MP Guide they are asking to Enabling Rules and Discoveries that are Disabled by Default.
For below:

I was not able to determine where I have to enable, please check snapshot:
Question 1: For this IIS MP Guide, Shall I enable all of what I get in the photo?
and the second doubt is about next snapshot:
Question 2: Where shall I override?
Thanks

The base class the rule is targetting is "Health Service" (see the "inherited from" column, that lists the class you'll want to override for provided you want to do an override for all the objects the rule is targetting, which is what it
sounds like you want). When you choose "override the rule" for that one it should say "for all objects of class: Health Servcie". Overriding that will override for everything the rule is targetting. You should be able to follow this logic for the rest
of them as well.

Compare date from snapshot tables

I have mothly snapshot tables in oracle database 10gR2 that I loaded in discoverer 10gR2 as it as business users want to query monthly data. Fine.
Now business users want to compare two months data something like:
'snap_date jan-2009' 'site_id for jan-2009' 'site_status for jan-2009' 'snap_date feb-2009' 'site_id for feb-2009' 'site_status for feb-2009'
01/31/2009 a0001P active 02/28/2009 a0001P inactive
01/31/2009 b0001P active 02/28/2009 deleted -
01/31/2009 c0001L active 02/28/2009 c0001L active
01/31/2009 - - 02/28/2009 z0001P active
They want to see it like:
'site_id' 'site_status for jan-2009' 'site_status for feb-2009'
a0001P active inactive
b0001P active site deleted
c0001L active active
z0001P no site found active
Please suggest, how can I achieve this in discoverer?
Two snap_dates can be any dates from last five years on which already snap_shot has been taken and added to the snapshot table.
Thanks.
Edited by: vkumar on Mar 17, 2009 2:17 PM

Hi Rod,
Actually this is just one table having snapshot data for different months like:
'snap_date'              'site_id'               'site_status'
01/31/2009           a0001P           active
01/31/2009           b0001P           active
01/31/2009           c0001L           active
02/28/2009           a0001P           inactive
02/28/2009           c0001L           active
02/28/2009           z0001P           active
From this table I want to compare data for different dates with respect to site_id?
Thanks.

Open Pages from Discoverer Report

Hi,
Is there a way to invoke a webpage or even better, an oracle function (that links to forms or self-service) from a discoverer report row ?
for example, I want a report for employees where the person looking at the report will click on the employee name and is taken straight to the person details page for that employee.
Regards.

Hi,
You can create a link to a form function using fnd_run_function.get_run_function_url. You can create a calculation either in a view or using a calculated item in the EUL (you will have to map the get_run_function_url in the EUL to do this). You then set the content type property of the EUL item to FILE so that when the item is selected in the workbook it appears as a hyperlink.
Most forms in apps except parameters so that you can pass the employee id to the form and the form will open up with the employee record. For example, if you are using a seed HR person form you create a calculation,
fnd_run_function.get_run_function_url(3494      -- PERWSHRG-404
                                     ,800       -- HR
                                     ,fnd_global.RESP_ID     -- caller's responsibility
                                     ,0        -- Business Group
                                     ,         -- Parameters
     'P_PERSON_ID='||TO_CHAR(person_id, 'fm9999999999999')||

Can not refresh snapshot changes after importing data of master site

Hello !
I have two database computer,one as master site,one as snapshot site.Because the error of the hard disk of master computer,I use the exporting data file to recover my database.after importing ,I found I can't refresh the refreshgroup on snapshot,who can tell me why?
thinks in advance!
(exp system/manager full=y inctype=complete file='/home/save/backdata/xhsdcomp.dat')
(imp system/manager inctype=system full=Y file='/home/save/backdata/xhsdcomp.dat'
imp system/manager inctype=restore full=Y file='/home/save/backdata/xhsdcomp.dat')
null

You haven't listed the errors that you're receiving when attempting to refresh your refresh group, but if your snapshots are attempting to fast refresh, I suspect it's because the creation timestamp of the snapshot log on the master site is newer than the creation timestamp of the snapshot. In this case you will need to do a complete refresh of the snapshot (or drop and recreate the snapshot) before you will be able to fash refresh it again.
If this is not the case, please post the errors you are receiving when you attempt to refresh the refresh group.

I am trying to print a snapshot taken from a PDF multiple times on one page.

Reader Will not print multiple copies of a snapshot on one page. I read the help files for Acrobat itself and all it said was take the snapshot and print it. Does anyone know if Acrobat can print multiple copies of the snapshot on one page?
From some reading in another forum page it looks like Acrobat can do it by saving the snapshot repeatedly with different names and the printing all of them at once. I really hate that workaround as I need to do this often.
Message was edited by: duckles10

I tried to do it using Reader. I have a one page PDF document with a UPS shipping label on one side and a special box label with a barcode on the other. This is designed to print on a standard 8.5 x 11 sheet of paper. There are many times when I need to be able to print the box labels more than once. At home, I do it by taking a snapshot of the box label and printing it to a Label printer as many times as I need it. The distributor who also ships items for me only has a full page printer but he can print 4 on a page labels on UPS provided stock. Reader won’t print a snapshot multiple times, the option is grayed out. What I wanted to know is if Acrobat itself can print that snapshot multiple times. I don’t think it can without being able to cut and save that PDF multiple times as separate files. That would be a slow and cumbersome operation. If it would take a snapshot or a single cut and save and print that PDF 4 times on a page it would be a reason to spend the money to buy the program because we need to perform this operation OVER and OVER on a regular basis. On some shipments we might need to print 12 or more extra box labels. We tape smaller boxes together for one UPS label and need to make sure EACH box gets a separate label. Otherwise they sometimes get lost on the other end.
Doing the save 4 separate PDFs process we might actually need TWO copies of Acrobat unless reader can print 4 on a page if it has 4 PDF’s to work from. I have not yet found a good way to save those snapshots from reader. I have tried since I found that it was possible to cut and save them in other formats but not PDF’s as reader can’t save them. The quality of the saved items in other formats is not acceptable. I recently discovered that Microsoft publisher which I have can save a document as a PDF. I’m going to see if I can import to that program next.

Discoverer Report

Dear Sir,
Can i access the report from cyber cafe(Web Enabled) that is generated with oracle 9i Discoverer. If YES then How ?
If NO then Why
OR
any other version from which we can access the report from cyber cafe that created with discoverer

Is it Correct " If You Don't have Licence copy of oracle S/w then u can use only development not for production for production you must have licence copy of oracle."

Discoverer Report Row Total

We are running Oracle BI Discoverer Viewer version 11.1.1.4.0. When we upgraded to this version we lost some functionality. In the previous version the report displayed the number of rows the query returned. Now the row totals display only under certain conditions. For instance, I have a inventory report name INV-REP-120 and it prompts the user for 6 parameters & displays 6 columns of data. One of the parameters is named ‘Keyword' and I’ll use this one in the problem description. When I set the keyword parameter to ‘HINGE’ The bar at the top of the results sheet it displays:
‘Rows 1-25 of 81, Columns 1-6 of 9’
When I change the keyword to ‘TUBE’ the viewer displays:
‘Rows 1-25, Columns 1-6 of 9’
The total rows are not displayed but the number of pages. It appears that if the total number of rows is less than 200 then the row total is displayed. I changed the rows displayed from 25 to 100 and scrolled down to the last page and now the reports displays:
‘451 – 458 of 458, Columns 1-6 of 9’
When I use the key word TEE I get :
‘Rows 1-50, Columns 1-6 of 9’
There are 596 tees, which would be about 12 pages of 50 rows. I noticed that at the top of table there is a field ‘Page 1 of 5.’ It looks like if there are more than 5 pages it does not display the total number of rows.
There seems to be some interaction between the total number of rows the number of rows per page and perhaps a setup on the back-end that determines whether or not the row total is displayed. How can I configure the viewer at the front-end and/or back-end to consistently display the row total for a report? Is there a Discoverer preference located in the pref.txt in the apps server that controls this?

Hi,
You can inform to your SP to edit the table EUL4_documents
and ask him to modify the name of the report that is stored in the column DOC_NAME .There is absolutely no necessary to open the work book that is stored in the database and change the work book name

Discoverer report not working on R12 !

We have just migrated to R12 from 11i and some of the discoverer query is not working, but the same is working fine when we ran thru SQL Developer or TOAD.
Is there any context (mo_global.set_policy_context) needs to be set in Discoverer report to get the data?
Thanks

Thanks Srini,
There is no any specific error message, the strange thing is if I run the Discoverer report is not returning any data, but if I set the mo_global.set_policy_context ('S',111) in SQL Developer or TOAD and then run the discoverer report it return data...
Any pointers?

i need to have sysdate as parameter in my report. I want data based on the date i provide.
how can i make this as an parameter?

Hi Prashant,
Subqueries are not Supported in Conditions..As of Disco Plus Rel 10.1.2.54.25
A plausible workaround can be:
1. Create a View with foll. Query
create or replace view TEST_VIEW as
select hpah.EMPLOYEE_NUMBER emp_no,hpah.FIRST_NAME,hpah.LAST_NAME,hpah.PERSON_NAME,
--hpah.JOB_NAME,hpah.ASSIGNMENT_ORGANIZATION_NAME,
hpah.ASSIGNMENT_TYPE,hpah.USER_ASSIGNMENT_STATUS,
SUBSTR(pj.name, 1, instr(pj.name, '.', 1, 2) -1) job_code,
SUBSTR(pj.name, instr(pj.name, '.', 1, 2) + 1) job_title,
(select haou.ATTRIBUTE1 from hr_all_organization_units haou
where haou.ORGANIZATION_ID = hpah.ASSIGNMENT_ORGANIZATION_ID ) Function,
(select haou.ATTRIBUTE2 from hr_all_organization_units haou
where haou.ORGANIZATION_ID = hpah.ASSIGNMENT_ORGANIZATION_ID ) org_desc,
SUBSTR(hpah.ASSIGNMENT_ORGANIZATION_NAME, 1, 6) dept_code,
SUBSTR(hpah.ASSIGNMENT_ORGANIZATION_NAME, 7, LENGTH(hpah.ASSIGNMENT_ORGANIZATION_NAME)) dept_title,
hpah.GRADE_NAME,hpah.LOCATION_NAME,hpah.SUPERVISOR_NAME,

and hpah.BUSINESS_GROUP_ID = ppb.BUSINESS_GROUP_ID
and hpah.GRADE_ID = pg.GRADE_ID(+)
and hpah.JOB_ID = pj.JOB_ID (+)
--and hpah.EMPLOYEE_NUMBER = 100779
order by hpah.EMPLOYEE_NUMBER
2. Create another table say TEST_TAB
create table TEST_TAB (emp_no, start_dt) as
SELECT hpah2.EMPLOYEE_NUMBER , MAX(hpah2.PERSON_START_DATE) PERSON_START_DATE
FROM hrfg_person_assignment_history hpah2
GROUP BY hpah2.EMPLOYEE_NUMBER
3. Add both of them in Disco Admin and create a join between TEST_VIEW.emp_no and TEST_TAB.emp_no
4. Bring both these Objects in a new report in Disco Plus
5. Create a New Parameter (Base it on PERSON_START_DATE Col of TEST_TAB)
6. Choose Option Create Condition with operator <=
7. Checkmark "Require User to Enter a Value
8. Execute Report
I believe this should work. Either ways let me know if it helps or u get another workaround. (This scenario looks quite interesting)
Thanks,

Discoverer Report Slow

Hi All,
I have a problem wherein some specific users are saying that the report is slow at their end.
The exact issue is...we have Discoverer Report present at the US server. Now we have 2 sites CANADA and US from where this report is run. Both sites refer the same server i.e. the US server.
Canadian users are reporting performance problems with this report, but when I run the report at my end there is no such problem.
Please advice what can be the probable reason for this.
Regards,
Ankur

Hi Ankur
Further to what has been said, if you are running Discoverer Plus across a long time it will take longer to run. Typically the query runs within the database but everything else, formatting, layout, page items and so on is done locally by the Java applet in your local cache. What happens if you run a CANADA report from the US site? Does it run ok? If so, then therein lies the answer. The machines in Canada need to therefore be as powerful as you can make them plus your network needs to be as fast as you can too.
Another way way I have seen this solved is by providing something like a Citrix server in the US for the Canadian customers to log into.
Best wishes
Michael
