How to determine the complexity of OBIEE report?

Hi BI Gurus,
We are currently planning to do OBIEE 11g upgrade. To do impact analysis, we have been asked to come with the complexity of all the reports which are now in OBIEE 10.1.3.4.2. I came up with the following points.
1) No. of tables used in the report - More no. of tables means more joins leading to complexity
2) Usage of Complex joins in physical layer
3) Complex calculations used in BMM layer
4) Usage of pivot tables, charts, guided navigation in the reports
Pls let me know if these are valid criteria to determine complexity. Pls add if anything else can be considered. Thanks in advance!

Hi,
Check data volume as well, as this is also impact your report performance.
If you are looking data model as well, then check table structure whether partioned, indexed etc.
Thanks

How to determine the Support Team from Reported-by?

Hi All,
We need to determine the support team based on reported-by.
I have concluded it is only possible by customization of developing ZBADI from these threads:
Re: How to determine the Support Team from the Reported by?
Automatic determination support team based on own specs?
Re: Route tickets based on Message creaters's location
So we have created ztable which has relation between SAP component, Reported-by and Support Team.
Now i need to develope a ZBADI and assign to the action definition SLFN0001_ADVANCED_FIND_PARTNER(i hope).
Can anyone help me out with the piece of code. Because i don't which FMs to be called for read and update the support desk message.
Note: Action definition SLFN0001_ADVANCED_FIND_PARTNER uses method call Z_CRM_DNO_PARTNER_1(which is a copy of CRM_DNO_PARTNER_1 and applied some correction as per note: 1041455).
Thanks in advance.

How to determine the database driver a report uses?

Hello experts. I'm using Crystal Report XI R2 and C# (.net 4.0 runtime).
For a given report, I'd like programmatically determine what database driver(s) a report and it's sub-reports use. The nice thing is that I don't want to change it.
When I refer to database drivers I'm talking about the choices one gets when starting a new report in the Crystal UI. Something like the following:
Access/Excel (DAO)
ADO.NET (XML)
Database Files
ODBC (RDO)
OLE DB (ADO)
I've looked into the developers help file that came with Crystal XI R2, crsdk_net_doc.chm, and can't find any references that would help. Maybe it's what I'm searching on.
My goal is for a given directory produce a list of rpt files that use OLE DB and a MS-SQL Server provider.
Thanks for looking at my question, any assistance is appreciated.
Mike

Also note since you are using 4.0 framework you must also be using VS 2010.
CR for VS 2010 is the only version supported with 4.0 framework.
See this page to download it: http://www.sdn.sap.com/irj/boc/crystalreports-dotnet
Or go back to VS 2008.
Code would look something like this:
     public class frmMain : System.Windows.Forms.Form
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc;
New subrepoutine...
            ISCDReportClientDocument rcd;
            rcd = rptClientDoc;
            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo oldConninfo;
            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo newConnInfo = new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
            CrystalDecisions.ReportAppServer.DataDefModel.Table oldTbl;
            CrystalDecisions.ReportAppServer.DataDefModel.CommandTable newTbl = new CommandTable();
            oldTbl = (CrystalDecisions.ReportAppServer.DataDefModel.Table)rcd.Database.Tables[0];
            oldConninfo = oldTbl.ConnectionInfo.Clone(true);

How to add two columns in OBIEE report?

Hi to All,
Can anyone tell me how to add two columns in OBIEE report and get that result in a new column?
Thanks in Advance,
Thenmozhi

Assume you already have two columns SalesAmt1 and SalesAmt2, and you want to derive 3rd column say SalesAmt3 which would be the sum of SalesAmt1 and SalesAmt2.
For this, as I mentioned above pull SalesAmt1 and SalesAmt2 columns in Report. Now pull another column (say SalesAmt1) and open the fx. Clear the contents of fx. Now locate the columns button in the bottom of the fx. From Here, first select SalesAmt1 and + sign and the select SalesAmt2.
Now in this new column, the fx should look like SalesAmt1 + SalesAmt2.
Let me know if you are looking for something else.
Thanks

How to determine the type of the jobject... similar to instanceof

hi,
I would like to know how to determine the jobject reference of an instance is of which class.
this is something similar to instanceof we use in java.
is there any thing like 'instanceof' in JNI. if there how to use it?
i got this as objective question for which answers were(i do not remember exactly)
1.instanceof
2.assignedto
i could nt het much help in googling.
thanks in advance

Hi
The JNI provides a native version to the java instanceof operator, this function takes two arguments
an object refrence and a class refrence and reports JNI_TRUE.
jclass myclass = env->FindClass("your class name");
if(env->IsInstanceOf(obj,myclass) == JNI_TRUE)
// obj is of type myclass

How to determine the u2018equivalent position of the same organizationu2019?

Hi,
"Position change is a transfer from one position to an equivalent position within the same org reporting structure and under the same chief position"
How to determine the u2018equivalent position of the same organizationu2019?
Cheers.

u can identity the position with help of the Holder
say for ex: A is the holder of the Position for Executive now the user performent an event called change of position so he changed to Manager (here we can find the chageing on the basis of some parameter so i have taken holder as Parameter as we dont know which has changed or wht has changed)
in this case we can use the report RHDESC20 se38
not an exact solution for ur question
will try to find some other way

Insufficient rights - How to determine the correct rights?

All,
Does anyone know how to determine the correct rights if you get the error message "Insufficient rights for operation"?
In SAP backend systems you can start transaction SU53 to check your "missing" authorizations, but is something like that also possible in MDM?
I also don't see any detailed information in the logs or reports.
If anyone has an good suggestion, please let me know, since I don't want to do "trail and error" to know what Functions to set to Execute and what Tables/Fields to set to Read/Write (because there are quite some combinations to check).
p.s. I've read the complete reference guide of the MDM console and sometimes it's really obvious what Functions and Tables/Fields you have to set, but for instance when I want to give authorization to maintain Relationships in the DataManager and have set the Main table and all Relationships to Read/Write and have set all Records and DataManager functions to Execute it still doesn't allow me to maintain the relationships on the records! I only get the message "insufficient rights" and it's unclear what rights are missing!
Regards,
Marcel

hi Marcel,
I doubt if we have anything in MDM to show you what authorizations are missing.However,you can check the following :
1. What activity are you trying to perform when you get this error.
2. Check if authorization are given in the role for that actitvity.
3. Check how many roles are allocated to user and Is authorization given in all roles if more than 1 role is assigned to that user?
Please let us know answer of the queries...

How to generate the ATR files for reports with out manually?

Hi all,
how to create the ATR files for reports in OBIEE 11g with out manually?
is there any other method to create the ATR files by using the OBIEE Server?
please provide me the solution for this?
we are creating manually for each and every report, it is time taken process how can we generate ATR files automatically
by using the OBIEE Server?
Thanks,

Hi,
I am afraid not.ATR are attributes files contains the object's full name, access controllist (ACL), description, and so on.Each catalog object has a corresponding attributes file, I am not sure why do you have to generate the atr files.In case you need info about atr files: http://businessdecisionsystems.com/blog/?p=7
If you have huge number of similar reports(with filter variations and same kind of layout), try to play around with the xml to minimize the development effort.

How to save the data of ABAP report into a notepad in desktop location???

HI all,
Can any one tell me how to transfer the data of ABAP report into a Notepad.
Actually I have to schedule a ABAP report in background on daily basis and I want to transfer the
whole record into Notepad.
If any program is available for this..please clearify the relevent code for transferring.
Thanks
Rajeev

declare a character type internal table.
now move your data from it_data ( internal table with data ) into table itab.
since you are running this report in background, you cannot save it to the desktop. Instead give any app server location
data: itab(400) occurs 0 with header line.
field-symbols: <fs1> type any.
data: gv_file type rlgrap-filename default 'TEST.TXT'.
data: gv_filepath type rlgrap-filename default <path>.
LOOP AT it_data.
    DO 100 TIMES.
      ASSIGN COMPONENT sy-index OF STRUCTURE it_data TO <fs1>.
      IF sy-subrc = 0.
        CONCATENATE itab <fs1> INTO itab SEPARATED BY ' '.
      ELSE.
        EXIT.
      ENDIF.
    ENDDO.
    SHIFT itab LEFT DELETING LEADING ' '.
    APPEND itab.
    CLEAR itab.
ENDLOOP.
concatenate gv_filepath '/' gv_file into gv_file.
OPEN DATASET gv_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc = 0.
    LOOP AT itab.
      TRANSFER itab TO gv_file.
    ENDLOOP.
    CLOSE DATASET gv_file.
ENDIF.

How to get the value from another report Customizes Form

Dear all,
I create a report such as
select * from mytable.table1
where field1 = :bind_variable
I create a menu to run this Customized Form and user have to select the bind_variable values. So I have another report created which also want this bind_variable as it WHERE Clause. But I don't want my user to key the same bind variable twice. They can just same the Customized Form and run for both report.
Could anybody know how to get the bind_variable on 1st report and used by the 2nd report.
Thank you very much.
Best Rgds,

Hi,
are you on BI7.0? There you can create variables type replacement path and get the value out from a different variable without any coding.

How to determine the ROWNUM in a Master Detail Form

Hello,
I am working in a Master Detail Form with Orders and Order Items Information; and I created a process that allows the users to select a Product ID on a tabular form, and the next column is populated automatically with the Product Description.
To achieve that, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:
<ul>I am using a wizard-created tabular form, instead of a manual tabular form; and </ul>
<ul>Instead of using another page as a Popup to pass the parameter of the ROWNUM, I am using a plug-in called “Tabular Form Super LOV” which is a modified version of the SkillBuilders’ Super LOV that works on Tabular Forms. </ul>
The Product ID is returned in the correct row by the plug-in; but in the case of the Product Description, it is always returned into the first row; and my problem is that I don't know how to determine the row where the user clicked to call the plug-in.
I set up an example in apex.oracle.com in case someone would like to look at it:
Workspace: ediazjorge
Username: test
Password: test
App Name: Sample App
App Number: 1550
BTW, I am using Apex 4.1.1.00.23 and Oracle DB 10.3.2.
Thanks in advance,
Erick

Hello VC,
Thank you for your time and help.
Unfortunately, it is still not working properly:
1. When the Popup LOV opens, the first row of the tabular form is 0, the second row is 1, and so on. How can I assign the values starting with 1 and in the format *0001* ? (I am still a novice on Apex and new to JavaScript :-), sorry about that).
--2. Also, when I close the Popup LOV, the value of P1_ROWNUM is ‘undefined’ again so I'm not sure if the Product Name column will be populated.--
3. And finally, you are using the jQuery Selector uPopupLOVIcon, which is an attribute of the Cloudy Theme. In my real application (Apex 4.1.1.00.26), my element looks like: *<img src="/i/lov_16x16.gif" width="16" height="16" alt="Popup Lov" alt="List" style="vertical-align:middle;" align="middle" />*. What do you recommend me to use as a jQuery Selector?
Again, I really appreciate your help and time. I think you solved the most difficult part.
Thank you so much,
Erick
Update: I just found out that the problem with my comment 2 is because I didn’t delete the previous dynamic action that set the value to P1_ROWNUM.

How to find the list of Queries/Reports which are using Exceptional Aggregation in SAP BI?

Hi All,
We are interested to know how to find the list of Queries/ Reports which are using Exceptional aggregation in SAP BI.
Please let us know is there any table's to check the list of reports using Exceptional Aggregation in SAP BI.

Hi,
Here you go..
1) Go to table RSZCALC and get list of ELTUID where AGGREXC is not INITIAL and AGGRCHA is not initial; now you get only exception aggregation set based on some chars. Also you can further add STEPNR = 1 since your intention is just to get query name , not the calculation details; this will reduce number of entries to lookup and save DB time for next steps.
Here you will get list of exception aggregation UUID numbers from which you can get properties from RSZELTDIR.
2) Pass list of RSZCALC-ELTUID to table RSZELTXREF - TELTUID and get list of RSZELTXREF -SELTUID - this table stores query to it's elements maping kind.
3) Now again pass RSZELTXREF - SELTUID into same table but into different field RSZELTZREF - TELTUID and get RSZELTXREF - SELTUID
This step you get query reference sheet or column or query general UUID for next step.
4) Pass list of RSZELTXREF - SELTUID into RSZELTDIR - ELTUID with DEFTP as 'REP'. Now you get list of query names in RSZELTDIR - MAPNAME and description in TXTLG.
Note: you can also get the reference chars used for exception aggregation from RSZCALC - AGGRCHA field.
Hope this helps.
Please keep in mind, it might take more time depends on how many query elements you have in the system...

How to determine the mount point for directory /tmp ?

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
I am installing Grid infrastructure. I am on step 7 of 10 (verify Grid installation enviroment) and get this error:
"Free Space: Rac2: /tmp"
Cause: Could not determine mount point for location specified.
Action: Ensure location specified is available.
Expected value: n/a
Actual value: n/a
I have checked the free space using the command:
[root@Rac2 /]# df -k /tmp
Output:
Filesystem 1k-blocks used Available Use% Mounted on
/dev/sda1 30470144 7826952 21070432 28% /
As you see above, the free space is enough, but could not determine mount point for /tmp.
Do any folk understand how to determine the mount point for directory /tmp ?
Thanks.

I have just checked "/home/oracle/.bash_profile". But in my computer, there is no "oracle" under /home directory.Is this your first time Linux and Oracle installation? I had a brief look at your referenced link. The reason why you do not find a "oracle" user is because the instructions use "ora11g" instead, which, btw, is not standard. The directories of your installation and your installation source can be somewhat different from known standards and you will have to adjust it to your system.
My best guess is that you have either missed something in the instructions or you need to ask the author of the blog what is wrong. The chance to find someone here who has experience with these custom instructions is probably unlikely.
I suggest you try to locate the cluster verification tool, which should be in the bin directory of your grid installation. Alternatively you might want to check the RAC, ASM & Clusterware Installation forum: RAC, ASM & Clusterware Installation

How to determine the field size

I am going to make a multiplatform application that hopefully
will run on linux and windows 2000.If the os is 2000, then I will use
vb.net/aspx else I'll use java servlets. I make the connection
to the web server ( through HTTP) not directly to database server.
So, the resultset will be stored in the String object. The columns
will be separated by delimeter. Our problem is how to determine
the size and type of the fields of mssql,oracle and postgres database
so that we can include it in the String object.
Ex.
String sResultSet=new String();
ResultSet rs=statement.executeQuery(sSQL);
while(rs.next()){
sResultset=sResultSet + rs.getString(field1) + "||" + rs.getString(field2) + "||";
vertical bars acts as delimeter
supposedly this is the code:
sResultset=sResultSet + rs.getString(field1) +"_" + rs.getFieldType() + "_"+
rs.getFieldSize() + "||" + rs.getString(field2) +"_" + rs.getFieldType() + "_"+
rs.getFieldSize() + "||";
supposedly this is the code if rs.getFieldType() and rs.getFieldSize() methods are existing
Anyone can give me an idea how to get the field type and field size of the database?
thanks in advance

Yes, but I dont know how to do it.
Can you give me an example of using it.
Thanks in advance
