Calculation in Discoverer Desktop

I am new to this forum, and pretty new to Discoverer so please go easy on me, and I'm sorry if I ask what seems like easy/stupid questions!
I am wanting to create a calculation to appear as a column against some data I have on my report.
My report shows data sorted by groups, one column is called Work Days Lost. I am wanting to do a calculation using another folder called Person Budget FTE.
However, when I create my rather simple calculation of the two folders Work Days Lost/Person Budget FTE, it only calculates on what is shown on screen. What I want it to do is calculate on Work Days Lost (what is shown on the screen - the groupings) but then on Person Budget FTE by department (Department is a Page Item which is chosen to show the data).
I hope this is clear?!!
Can anybody help by providing the calculation that I should use - I guess what I really need to do is group the Person Budget FTE by the folder Dept?
Thanks in advance

Hi Chariot,
It's not exactly clear to me what you want, but it sounds as if you need an analytical function. That's SQL functionality, so in your calculation you can use something like:
sum(budget) over (partition by dept, order by dept).
You can look up this functionality in either the SQL reference or the Discoverer User guide (in the Discoverer tutorial are some excellent examples).

Sabine

How to use Oracle OAB Fast Formulas in Discoverer-desktop [ for reporting]

Hi,
Can anyone tell me how to use a fast formula in discoverer-desktop [for reporting]. Currently, we have a disco-report that calcuates the 'monthly salary', but we don't want to use that. Instead, we have a custom fast-formula [xx_oab_monthly_salary] which has the conditions and calculations that we need.
I want to use that formula in discoverer-desktop directly and get the monthly-salary.. i.e., someone needs to create a folder under the business area and add it i believe.. the formula internally calls a function.
when i checked about this with my dba - he said, he can add the 'function', but not the formula. and i need to write the calculation part...
does anyone know how to add it...there shud a way right...
i do not have access to the technical-stuff here..
someone said ["you can wrap the FF_EXEC.run_formula call into your own pl/sql function and map this function into the EUL so that the formula can be called from a workbook.", but this talks about pl/sql-do we need pl/sql
for this].
also, someone else said [ some fast formulas need specific contexts to be set. Depending on whether the fast formula below the only fast formula that you want to recreate in Discoverer.
For a single formula, in general my recommendation is to recreate the fast formula instead of using the ff_exec call].
any quick answers greatly appreciate..
thx,

Hi,
That's right you need to develop the pl/sql function outside of Discoverer using a pl/sql tool or just SQL*plus. I haven't an example to hand, but can dig one up if you need it. Once you have the function developed you can map it into the EUL using Discoverer Administrator. It will then be available to Discoverer Desktop/Plus as a database function when creating calculations. So you can then just add the calculation to an existing or new report.
Alternatively, you can build the pl/sql function into a view and load the view into a new folder using Discoverer Admin.

Error when running a report in Discoverer Desktop

All -
I run a report in discoverer desktop and got the following warning message: This sheet currently contains no data.
I generated the query by using the sql inspector tool and run the query in the database and, to my surprise, it showed the correct records.
I don't know what is causing this error.
I checked all items (in discoverer administrator) that are used in by report and everything seems to be ok.
Any idea?
Thanks,
Daniel.

Hi,
There could be many reasons for this, what is in the query you are running?. It could be a bug in your version, what version are you using? Does it happen with one workbook or all workbooks? It could be an NLS Language problem, check that the calculation USERENV('LANG') returns the language you are expecting in Discoverer desktop. It could be a problem with the context for your session, are you using an apps mode or database mode EUL?

How to add the USER who logged in discoverer desktop to the title

i want to add the user name on the title above the page body of discoverer desktop next to the &DATE and & TIME in title

Hi,
When adding to the title:
The default available on the Insert menu is the full page item list &PageItems.
However the undocumented way to add a single page item is to type &PageItemName which in this case will be the calculation item for the USER function.
For example:
Calculation TheUser defined as USER.
Place TheUser on pageitems area.
Add &TheUser to page title (does not require &PageItems to be present)

All the SQL functions - to use in Discoverer-desktop reporting?

Hi ,
Can anyone tell me where i can find all the SQL functions, <conditional stmts> etc - to use in Discoverer-desktop reporting?.
Thx, Sree

Hi,
I am not quite sure what you mean. You can see all the functions available when you edit a workbook. Create a calculation and select the functions, your custom functions will be under database functions. Conditions are on the condition tab.

Using views to show data in discoverer desktop

Dear ALL,
I am facing an issue in development of Relational reports in Oracle Discoverer Desktop.
Following are the details of my warehouse (Data Mart) database:
There are 2 Dimensions and 1 cube in the Data Mart. All the 2 dimensions and Cube are based on tables Currency, Accounts and Fact_Data respectively in our Data Mart.
Fact table contains 2 facts (CLOSING_BALANCE,MAX_BALANCE) and and the values are stored in USD currency.
The fact table contains 100,000 rows with all values/facts in USD currency.
Details of EUL(End User Layer):
I have derived all 2 dimensions and cube from OWB, which generates all the "Business Definitions" and "Business Areas".
Issue:
I need to show the end user a report (from discoverer) which shows all the values/facts in PKR currency.
What is the best way to get this report?
I have tried many methods, including "Creating a Materialized View (MV) on fact table which contains converted values in PKR and then making a view (Union of fact table and MV) which gives me 200,000 rows." But this solution has an issue that i can not join the View with other dimensions in Discoverer because View contains dimension keys (same as fact table) and dimension tables contain Surrogate Ids.
Thanks in advance for your help and suggestions.
Best Regards

Hi,
Then you should be able to import your exchange rate table as a new folder in the EUL, join this folder to your fact table using date and create a calculation for the converted currency.

Average no value in crosstab report (Discoverer Desktop)

Hello experts,
I have a crosstab report, and i want to use avg to a calculation field, but in crosstab i have no values and when i make drill down i have values under my group.
how can i solve this?
Edited by: user13062021 on 18-Feb-2011 07:44

I make this change to my values "nvl(<item>,0) but nothing happened. In discoverer plus the values are correct but in discoverer desktop the values are null.
Instead of this in analytical sheet i do not have null values to this column.
For your information,
in analytical sheet i have a calculation field with round and nvl functions, and i calaculate this field from the analytical sheet to crosstab sheet with an AVG() function, and cannot claculate.
When I first make this sheet the values in discoverer desktop are all correct, but on the other day when I make refresh to my sheet the values are null.

Discoverer report - Output from Discoverer plus is not the same as Discoverer desktop

As a part of Upgrade project we are migrating the discoverer reports from 11i (11.5.10.2) to R12 (12.1.3) .After migrating to R12, for a custom discoverer report the output given by discoverer desktop is correct (24 rows for a scenario). But the report output from Discoverer plus does not show the credit transactions (2 rows). The output from Discoverer plus shows only 22 rows (24 - 2), which is incorrect. The query is the same in Discoverer desktop and Discoverer plus.
Please let me know why these transactions that are appearing when the report is run from discoverer desktop are not appearing in discoverer plus. Is there any setup in discoverer plus for this?
Regards,
Brajesh

Pretty hard to answer a question like this. Best bet would be to copy the existing discoverer plus book and start removing conditions, fields, etc until those two rows from desktop show up and see if you can work it out.

Checkbox in discoverer desktop edition

Hi,
The query we are executing created for cross tab report have plenty of views and is returning null data which needs apps intialization which cannot be done from discoverer.
I think loging into Discoverer desktop edition with oracle applications user would resolve the same.
I have checked the checkbox in desktop edition and logged in as operations/welcome. but it is showing as invalid user name /password.
please help in setup that must required to check and login to oracle applications user. Also Provide if there is any alternative.
I would be very much thankful if you could help me on this.
Best Regards,
Katty.

Hi,
The apps initialization can be done by Discoverer provided that you are connecting to an Apps mode EUL with an applications username and password.
You must specify that you want an Apps mode EUL when the EUL is created. Then when you connect to Disco Admin as the owner of the EUL you will be able to grant access privs and security to the Application users and responsbilities.
If you have an apps mode EUL and still get an invalid username/password then this could be because the application is running in secure mode. Then you need to copy the .dbc file to a local directory. Search this forum for details on how to do this.

Discoverer Desktop crash

When trying to open a report created by a colleague, Discoverer immediately throws a Windows (Vista 32Bit) error that "Oracle Discoverer Desktop has stopped working". I click close program, and Discoverer closes. It's a very simple report so I recreated it yesterday, ran it fine, could change parameters for different outputs, no problems. This morning I log in and when trying to open the newly created report from yesterday, same error. No exception, no memory pointers, nothing, just the Win error that it has stopped working.
Anyone seen this before? Running Discoverer Desktop v 10.1.2.3 Client v 10.1.2.55.26.

My colleague was able to open and modify the report that I created without issue so I suspect the report is alright, perhaps my installation? Odd that I can run many other reports just fine in the same environment and that this one ran fine from development, but as soon as I closed it to reopen, no luck.

Hi,
I have the same issue with Discoverer Plus 10g Rel 1 (10.2.0.2 )
Desktop and Administrator are working good. So, I cannot resolve it by re-installation.
Also, this is not reproducible. Sometimes it works very smoothly, but sometimes it gives error for the same report.
Any idea ?
Thanks!

Discoverer Desktop Graphing Questions

I have several questions about the graphing tool in Discoverer Desktop:
1. I'm bringing in a customer id field which I convert with a to_char in the query from a numeric field. Most of them are 5-digit, but some are 4. I notice in the x-axis the customer id's appear only for the 5 digit id's, and for the 4-digit ones the identifier appears. i.e. if the 5th record has an id of 1508, instead of displaying 1508 it displays 5. Does anyone know how to correct this?
2. In the y-axis values, is it possible to display more than 5 decimal places? (We're dealing with very small percentages). When I try to enter 6 or higher as the decimal value in Options, it says invalid number.
3. When I open an existing workbook, it readjusts the y-axis scale to a max of 1, when I've set it to .0001. How I can I make this retain my scale values?
4. Is it possible to display the y-values in the graph area itself next to the plot points?
Thanks for any help!!!!

Hi paul,
Its a good idea to upgrade from 4i to 10g 4i is no more used by many and their are some issues or bugs with it.The latest version is 11g which has been released 1 week back.If not go with 10g version available.
1) Do all reports have to be stored on the database to allow them to be accessed by Plus or Viewer? Can only the 10G client version open files from a local hardrive or shared network drive?Yes they have to stored in the database so any ened user can access them from plus or viewer.
Can only one report be open at any given time with Plus or Viewer? In client it is possible to have 2 reports open at the same time to facilitate easier comparisons.Yes,if the reports are registered as different reports and if the end user has access to both the reports thn he can open and compare it OR if both reports are in same workbook as different sheets than its easy to view or compare.
NULL values are still showing the word "NULL" even though in Tools Options we have set it to show blank, existing reports are still using the NULL value.It should show blank,might be some problem.In discoverer 10g i think you will not find this issues.
Hope this helps you.
Best Wishes,
kranthi.

Discoverer Desktop 10.1.2 error while opening the report.

Hi ,
Do you know why I would be able to open a report from a Discoverer Plus responsibility in Oracle Financials but not from Discoverer Desktop?
The report was owned by User1 and shared with both Admin1 and AdminUser1. I have tried accessing the report with both user names, and in both cases, I get the error shown below when I am logged into Desktop but I do not get the error when I log in through the application.
Error message:
Join configuration cannot be resolved. Reason: more than 1 of the detail folder uses non-aggregated items
Thanks!

Discoverer Desktop Report issue

Hi,
One of my user is facing a format issue while running the report in Oracle Discoverer 10g. The report produces the following out put.
count(Col A)     Col B     Col C     Col D
12          A     200709     12-Sep-07
11          A     200709     21-Sep-07
24          B     200709     11-Sep-07
32          B     200709     13-Sep-07
10          B     200710     15-Oct-07
Col A is of number data type, Col B character, Col C is number and Col D is date
if Col D is removed from the report, the user is getting the result in following format
count(Col A)     Col B     Col C
23          A     401418
56          B     401418
10          B     200710
i.e. col C displays the sum of the value based in Col B instead of displaying it as 200709.
but when I ran the report from my end I'm getting the result in a proper manner.
count(Col A)     Col B     Col C
23          A     200709
56          B     200709
10          B     200710
Please help me in sorting out this issue.
Environment Details:
Oracle Discoverer Admin 10g(9.0.4)
Oracle Discoverer Desktop 10g (9.0.4)
End User Layer 5.0.2
Thanks in Advance.
Regards,
SS

@Himanshu3jul:
I'm not using any Oracle Application secure views. Also, the data that are being displayed is proper if Col D is not removed. If user removes Col D, the result is getting aggregated based on Col B but for me it is showing in a perfect manner.
@puppethead:
I'm afraid I may not be able to the check the registry on user machine since user is sitting at a different location.
@Rod West:
The default Aggregate property for Col C is set to <none> and it is grayed out. I'm not able to change it too. Also, if it is a bug then I should get the result as what user receives but I'm not facing any issues in that report but only user is.
Please let me know what can be done next to figure it out.
Also, I have the screen shots from my machine and from user’s. if you think that it will really help then I can post it. please let me know where and how I can post it so that you can have a look at it.
Thanks,
SS

Report Layout difference in Discoverer Desktop and Discoverer Viewer

Hi,
A report was developed in Discoverer Desktop. It is having some 10 columns as data points. The summarized columns for those 10 columns are required. But only 3 columns should be displayed in Detailed Data Points. So we shrinked(brought together) all the unwanted columns keeping 3 datapoints displayed. Now it is working fine in the discovere Desktop. But when we open the same report in the Discoverer Viewer, all the 10 columns are displayed in the Detailed Data Points as well.
Thanks in Advance
Regards
Rakesh

hi Michael,
good morning..hope u had a good sleep.
as per your last thought y'day, even though i create a function for the sum of season values n select those columns into the report, those will not be shown as summarized columns on right hand side of the report. they will be shown as datapoints for every month in that selected season.
i think the only possible solution for like this report is to hide those unwanted columns. for this we have hidden checkbox option in tools->sort while developing. but this option is available only for tabular reports.
if u come up with any fresh solution for the fresh day...i am glad.
Thanks,
_Rakesh.
