Calculation in Discoverer 3.1

Hello,
I need a special calculation for my report. I'm not a trained user of Discoverer but like get become one.
Let's say I made a workbook reporting an article code, the present stock of that article and the sales of that article for the past 6 months each. Now I need to know the average consumption of that article? I guess it should be the SUM of all reported sales in the workbook. To get the average, just divide by 6. Am I right?
Now I also need to calculate how long (in months) my stock will be sufficient, before I have to order again. This calculation should be based on the sales average of the past 3 months. In terms of speaking this should be something like: Stock/((SUM of Sales month 4+5+6)/3)
Example:
Stock=10
Sales month 1=2
Sales month 2=4
Sales month 3=6
Sales month 4=0
Sales month 5=5
Sales month 6=3
Total Sales 6 months = 20
Average consumption 6months= 20 / 6 = 3,3333
Total Sales latest 3 months = 8
Average consumption latest 3 months = 8/3 = 2,6666
Months on hand = 10 / 2,6666 = 3,75
It could be easy to export the workbook to excel and finish the job their, but I like to offer a complete workbook in Discoverer to the end user, so that he just has to select his sales period (parameter) and get the result as shown above).
Is there anybody out their how has the answer for me?
Thx
Rudi

"I need a special calculation for my report."
When I'm confronted with calculations that are too complex to produce in a workbook. I generally solve it the Administrator Edition, making a Custom Folder using SQL.
I do hope you have some SQL knowledge, otherwise this tip is useless.

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).

Problems with Custom Total Calculation in discoverer

"Totals " feature provide only standard functions as below:-
Sum, Average, Count,Count Distinct, minimum,max, std dev,variance,% of grand,Cell Sum...
But in real world scenarios we should be able to put conditional totals & formula based totals leveraging Statistical SQL functions in totals.
Many ppl have asked this problem in previous posts, but none got them any reply :-
An example:-
Few months back, somebody asked the following problem:-
I have a database where the data is broken out by levels (ie. Level 1, Level 2, Level 3). Level 1 contains 3 values, REVENUES, EXPENDITURES and Other. The customer wants to see the total of REVENUES, the total of EXPENDITURES, and the total of Other. This is no problem... I just created a total in desktop that breaks at change in Level 1. However, the customer also wants to see the difference between the totals of REVENUES and EXPENDITURES. I must be brain-dead, but I can't figure out how to do this! PLEASE HELP!
Any help in this matter from anyone (esp. from oracle Discoverer product development group ) would be highly appreciated
Thanks
Puneet

Not clear what part of the code doesn't work. Assuming that you did check that the code you wrote executed
the problem may be the following.
You need to add partial trigger on the destination component.
Add ...
oddShoeVo.executeQuery();
AdfFacesContext.getCurrentInstance().addPartialTarget(HERE_THE_BIND_NAME_OF_YOUR_TABLE);
Also I don't see that you acctually use View Criteria. There are specific way to apply View Criteria programatically and I don't see that you use it.
The simpliest way is just to change the VO query to embed bind variables into the query
E.G.
select 1
from dual
where some_column= :P_PARAM1

Business object to Discoverer

Hi All,
Any documents available, for migrating reports from BO to Disc?
Thanks

I too am not aware of any way to migrate Business Objects reports to Discoverer.
We are coming from a B.O. environment, though we are in the midst of an ERP implementation (non -EBS to EBS) so we are starting from scratch. Here are some of my thoughts:
-If your data sources are not changing (e.g. your data warehouse or your relational database), I would closely examine your existing universes. I would anticipate a correspondence between your B.O. universes and your business areas in Discoverer. I would encourage creating ER Diagrams of the existing universes and this would be the building blocks for your work in Discoverer. I too am unaware of any nice tools to ease your pain.
-I like John's suggestion: You could maybe look at doing custom folders, where you could copy in the SQL statement, and then rebuild the report in Discoverer from that custom folder
-Our B.O. universes were pointing at a relational database and so we heavily leveraged using multiple Business Objects data providers with manual links between them. There is nothing like this in Discoverer. Brace yourself if you relied on this. This has been somewhat painful for me.
-Discoverer appears to have more functions available in creating calculations.
-Discoverer appears to me to be more rigid in totaling.
-Discoverer has features to allow calculations that take into consideration context (like groups) that are similar to B.O., but feel less intuitive. I hope I change this feeling, but right now they feel awkward yet.
-A lot of our old B.O. reports had multiple tables on one tab. You cannot do this in Discoverer. Discard any thoughts of trying this.
-If your company has great aspirations for using the Discoverer scheduler, please lower its expectations. Emailing and output to files in multiple formats is not out of the box. Armstrong's book does provide some good alternatives if you still have great scheduling aspirations.
-Memorize the Armstrong's Oracle Press Discoverer book.
-Lastly, the user community does not seem/feel nearly as big, but people try to help one another.
In many respects, I am still learning a lot (I have only been seriously working with Discoverer for about 8 months). If I made a wrong assertion, I am sure someone will correct me.
Prepare yourself for a lot of work.

User Aggregated Function in Discoverer

Hi.
I'm trying to use an "User Aggregated Function" in Discoverer. This function concatenates a varchar field, and I want to use as a max(), min() or count() functions, but Discoverer always write this function in the group block of the query, and the databse generates an error.
This is the user agrgegated function:
CREATE OR REPLACE function DDS_UXXIINV.var_agg (input varchar2) return varchar2
parallel_enable aggregate using agg_t;
The package agg_t is defined as:
create or replace type agg_t as object (
str_agg varchar2(4000),
static function ODCIAggregateInitialize(sctx in out agg_t)
return number,
member function ODCIAggregateIterate (self in out agg_t,
value in varchar2 )
return number,
member function ODCIAggregateTerminate (self in agg_t ,
return_value out varchar2,
flags in number )
return number,
member function ODCIAggregateMerge(self in out agg_t,
ctx2 in agg_t )
return number
create or replace type body agg_t is
static function ODCIAggregateInitialize(sctx in out agg_t)
return number is
begin
sctx := agg_t(null);
return ODCIConst.Success;
end;
member function ODCIAggregateIterate(
self in out agg_t, value in varchar2)
return number is
begin
str_agg := str_agg || value;
return ODCIConst.Success;
end;
member function ODCIAggregateTerminate(self in agg_t,
return_value out varchar2, flags in number) return number is
begin
return_value := str_agg;
return ODCIConst.Success;
end;
member function ODCIAggregateMerge(self in out agg_t,
ctx2 in agg_t) return number is
begin
str_agg := str_agg || ctx2.str_agg;
return ODCIConst.Success;
end;
end;
When I use this functions (as a calculated field) Discoverer generates this statment:
select var_agg(field1), field2 form table group by var_agg(field1), field2;
I want this statement:
select var_agg(field1), field2 form table group by field2;
Sometimes Oracle generates a error messages saying that there's a wrong combinations of joins (translated from spainsh)

Hi,
Unfortunately, you cannot import user defined group functions into Discoverer, Discoverer does not understand them.

Totals

I did a calculation in discoverer desktop COUNT_DISTINCT(X)
It works fine but when I'm trying to du a total Grand sum of the column it does not show. If i try to do a count it shows.
What can I do to make the Sum show at the bottom of the column?
I'm using discoverer 4.1.48.06.00
//Åsa

Hi
To further add to what Russ has said, if you are joining to more than one folder please check the direction of the joins. If these are correct or you still have issues it sounds like you could be in a fan trap situation.
Discoverer will not compute aggregations if it thinks there is the possibility of a many-to-many join. Even if you insert code to work around this, Discoverer just looks at the join definitions in the EUL and says - uh oh - this could be a fan trap.
To prove it, try changing the type of join to being 1:1 and see what happens. If it now works then you are in the fan trap domain. You need to be very careful about continuing with that query and please don't export the data to Excel. One of the biggest mistakes folks make is exporting fan trap data to Excel and then getting Excel to compute the totals. The totals will be wrong - I guarantee it. This is one of the reasons why, if at all possible, you should remain within Discoverer.
Does this help at all?

Analitics functions

Hello, I have one worksheet that are giving me more problems. The question is:
-I have a crosstable with this elements: cod in aix y and a years in the aix X. I have a page item too.
-I have two calculs : sum(nom_ins)over(partition by date) ( the total by date) and nom_ins ( the detail for cod _in )
But where i show the results, for the aggregate calculs, when discoverer find two rows and sum nom_ins because there
are aggregables, no show me the result of the analitic fuction.
Here is an example:
data
cod_ins jan
nom_ins sum(nom_ins)over(partition by date)
1 1 5
2 1 5
3 2 (here no result, not null)
4 1 5
thank!!

I also am having problems with analytical functions.

Help in building the Cacluclation

Hello,
I am trying to convert the below SQL into discoverer report.
In SQL I am getting exactly what I wanted from SQL plus output, but when I try to build calculation in Discoverer I am not getting any value in the calculated column.
select plan_id, END_DATE, SUM(usage), SUM(CASE WHEN STATUS = '2' THEN USAGE ELSE NULL END) from usg_TBL a, CUSTOMER b
where a.acct_id = b.acct_id GROUP BY PLAN_ID, END_DATE
I created calculation in Discoverer based on the following
SUM(CASE WHEN STATUS = 'NEW' THEN USAGE ELSE NULL END)
Please help me to find out where I am making the mistake.
Thanks in advance

Hi,
Maybe you want:
SUM(CASE WHEN STATUS = '2' THEN NVL(USAGE, 0) ELSE 0 END)

Discoverer: "CASE WHEN...." in calculations won't show anything in GUI !?!?

Hi all!
I have a report in Discoverer Plus (Version 10.1.2.48.18) which contains 2 columns: One with actual spendings and one with budget figures. I want to make a third column which holds actual spendings in percentage of the budget. To do this, I need to make a calculation similar to:
CASE WHEN SUM(budget) <> 0 THEN SUM(spendings)/SUM(budget) ELSE NULL END
However, when I apply this calculation to the third column, my report don't return any numbers at all in any column.
What am I doing wrong? -- Is this a bug, and how should I solve my problem?
~Morten

I can get something out if I do this (applying an aggregate function to it all):
SUM(CASE WHEN budget <> 0 THEN spendings/budget ELSE NULL END)
However, this is wrong (Summarizing these percentages doesn't give any meaning).
SQL lookes something like this:
SELECT /*+ NOREWRITE */ o100448.ACCOUNT as E100451,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM'))) as E101004,MAX(o100448.ACCOUNTNUM) as as100473_100451_NEW,CASE WHEN ( SUM(o100862.BUDGET) ) <> 0 THEN ( SUM(o100862.AMOUNT) )/( SUM(o100862.BUDGET) ) ELSE NULL END as C_1,( SUM(o100862.BUDGET) )*o100448.SIGN as C_3,( SUM(o100862.AMOUNT) )*o100448.SIGN as C_2,GROUPING_ID(o100448.ACCOUNT,o100448.SIGN,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM')))) as GID

How can i use calculation from one sheet into another sheet in discoverer

I have a function which has to be used for several calcualtions in discoverer report.For each row the function is called 8 times, Is there any way that i can create a caculation based on the function in one tab and use this value returned by the function in the other tabs in the discoverer so that i can eliminte the function being called 8 times for each row.
Please help.

Hi Lloyd ,
Thanks for the reply. See below for the detail explanation of what i am Talking about.
I am Developing a Operational Expense Report based on a Custom Table.
I get the following columns from the custom Table - Account, Amount Manual, Amount Local, Amount Overseas.
Then I have two Functions which Calculates two different Ratios Based on the other Custom Table.
1st function - Qualifying Sales Ratio
CREATE OR REPLACE FUNCTION xxwfs_avi_q_sales_ratio (p_period VARCHAR2)
RETURN NUMBER
IS
v_q_ratio NUMBER := NULL;
BEGIN
SELECT ROUND ((a.nonqualified_ar_amount / b.nq_nq_ar_amount), 4) qualifying_sales_ratio
INTO v_q_ratio
FROM (SELECT SUM(NVL(gp.total,0)) qualified_ar_amount
FROM xxwfs_gp_table gp
WHERE gp.company = 24101
AND gp.gtp_qualified = 'Q'
AND gp.org_id = 126
AND gp.gl_date >= p_from_date
ANDgp.gl_date <= p_to_period) a,
(SELECT SUM(NVL(gp.total,0)) nq_nq_ar_amount
FROM xxwfs_gp_table gp
WHERE gp.company = 24101
AND gp.gtp_qualified in( 'Q','NQ')
AND gp.org_id = 126
AND gp.gl_date >= p_from_date
ANDgp.gl_date <= p_to_period) b;
RETURN v_q_ratio;
EXCEPTION
WHEN OTHERS
THEN
v_q_ratio := 0;
RETURN v_q_ratio;
END xxwfs_avi_q_sales_ratio;
2nd Function - Nonqualifying Sales Ratio
CREATE OR REPLACE FUNCTION xxwfs_avi_nq_sales_ratio (p_period VARCHAR2)
RETURN NUMBER
IS
v_q_ratio NUMBER := NULL;
BEGIN
SELECT ROUND ((a.nonqualified_ar_amount / b.nq_nq_ar_amount), 4) nonqualifying_sales_ratio
INTO v_q_ratio
FROM (SELECT SUM(NVL(gp.total,0)) nonqualified_ar_amount
FROM xxwfs_gp_table gp
WHERE gp.company = 24101
AND gp.gtp_qualified = 'NQ'
AND gp.org_id = 126
AND gp.gl_date >= p_from_date
ANDgp.gl_date <= p_to_period) a,
(SELECT SUM(NVL(gp.total,0)) nq_nq_ar_amount
FROM xxwfs_gp_table gp
WHERE gp.company = 24101
AND gp.gtp_qualified is not null
AND gp.org_id = 126
AND gp.gl_date >= p_from_date
AND gp.gl_date <= p_to_date) b;
RETURN v_q_ratio;
EXCEPTION
WHEN OTHERS
THEN
v_q_ratio := 0;
RETURN v_q_ratio;
END xxwfs_avi_nq_sales_ratio;
The report is Run based on the parameter for the Range of gl_date.
I registered these functions in discoverer and passing the parameter values to calculate the ratios. The 2 ratios are just one time calculations for the range of gl_date the report is run.
The i mulitiply Qualifying Sales Ratio with the columns Amount Manual, Amount Local and Amount Overseas to get Qualifyied Amount Manual, Qualified Amount Local , Qualifyied Amount Overseas and the Nonqualifing Sales Ratio with the same Amount Manual, Amount Local and Amount Overseas columns to get NonQualifyied Amount Manual, NonQualified Amount Local , NonQualifyied Amount Overseas.
This is the design i am approching now. For each record the function is called 8 times to calculates the qualifying and Non qualifying Sales ratios Ato caculate the other 6 columns based on these Ratio Calculations.
So i was thinking if there is any way that i can get the Ratios for a specific date range in the First tab and usethe Value of the ratios in the other tab so that the function call is minimized.
Waiting for your replies.

Hi,
In the report I have two worksheet. The Ist worksheet has the same calculated columns as 2nd worksheet. Even the calculations are also the same. The only difference is I use different folder for the 2nd worksheet. For 2nd worksheet layout only the calculated columns will not display the result.The other columns displayed the result properly. Even in the Ist worksheet all the columns including calculated columns displayed the result correctly.The calculations are same in the 2nd worsheet with calculation names different and items coming from different folder. As these calculations are working properly in Ist worksheet,why its not appearing in the 2nd worksheet? The query I paste before is the Discoverer show sql query for 2nd worksheet.
Please help.

Some Calculations are not working in Discoverer 10g after upgrade from 4.1

Hi Gurus,
We are recently upgraded Oracle Discovere 10g from 4.1, some calculations are not working in Discoverer 10g. I appreciate if you could fix below calculation(s) in 10g.
CASE WHEN TRUNC("Expenditure Item Month") = '31-JAN2007' THEN SUM(Wtd Qty A) WHEN TRUNC("Expenditure Item Month") = '28-FEB-2007' THEN SUM(Wtd Qty A) WHEN TRUNC("Expenditure Item Month") = '31-MAR-2007' THEN SUM(Wtd Qty A) END
Thanks & Regards
Vikram

Sabra,
Not sure exactly what this might be... there could be an issue there.
Please make sure that you review the upgrade.log. Are there any errors / warnings?
Also, you might wanna peek the Metalink Note:262623.1 - Master Note for OracleAS Portal Upgrade Issues, where you'll find some nice things where to start looking at.
Later you may wanna open a Service Request into the Oracle Support.
I hope it helps...
Cheers,
Pedro.

Calculation shows Blank or NULL in Discoverer Viewer but not in Dis.Desktop

Hi All,
I built a crosstab workbook. I've a calculation between rows and columns, it is a function that I created in the database and I pass parameters to it.
In Discoverer Desktop it shows correctly. However in Oracle Viewer doesn't appear the value. What can I do?.
I really appreciate your help.
Regards.-

Hi Mariano
While you can send Oracle a DIS file they will not be able to do much with it unless they have your EUL and data. If you are able to replicate the issue using the Oracle Video Store EUL then I'm sure they would be easily able to help.
I think the solution lies in where we have been looking together. As I have commented to another person recently with issues like this the easiest way to understand what is going on is to bring more detail data items into the worksheet and then home in on where the issue lies.
Have you turned off the fan trap protection? If you have then Discoverer will run a query that contains a fan trap but will then not compute the totals. This is correct. If you try to compute totals with a fan trap you WILL get the wrong answer. Many users who do not understand this export the data to Excel and get Excel to compute the values. These users then say that Discoverer has a bug. In this scenario Discoverer is doing the right thing.
So, could you be in a fan trap? If yes, then you need to resolve the fan trap. One way to test this would be to change the joins between the folders to 1:1. Discoverer will not think there is a fan trap and will more than likely compute your sub-totals and totals. Assuming the 1:1 trick works, you can either leave it in place or dig deeper, fnd out why and then fix it.

Need Urgent Help on Calculation items issue In Discoverer Plus

Dear Discoverer Experts,
I would need help on the below scenario:
A
147644.08
147644.08
Maximum: 147,644.08
B
142494.65
5149.43
Sum: 147,644.08
C
5149.43
142494.65
0
Here A, B, C are columns and C column is Calculated Item(A-B) and Maximum and Sum are Totals items, everything working fine.
The intent is that I would need the difference between totals items I mean Maximum and Sum , i.e Maximum-Sum (147,644.08 - 147,644.08) =0(in this case), but I am not able to get it, can anyone help me on this that would be greatly appreciated.
Thanks

Thanks Tamir for your response, i am getting ZERO
But when i create new calculation item for examle TEST with calculation MAX(A) over () - SUM(B) over ()
then i am getting new column next to C with name TEST and with two rows of data with 0 (Zero)
like this
TEST
0.00
0.00
why am getting two rows of data, and that too can't we get this ZERO under C column at the same Row as MAX and SUM
(Or)
if not possible then after adding coumn TEST next to C column can we get ZERO in the row as MAX and SUM
either way would be fine, can any one hlep on this issue.
Thank you
