Variable and Formulas Question

Hi folks,
I use BOXI r2 sp 4 and I have a general question re: variables and formulas in Webi reports.
Billing Year Month and Cost of Service are standard time dimensions and measures that I use in my Webi reports and they were created at the semantic level.
Normally, I create cross tab reports with the Billing Year Month along the horizontal axis and the Cost of Service in the Body (Business Unit or Department would be placed along the vertical axis).
For some reason, when I use formulas/variables to modify the standard time dimensions (like changing Billing Year Month to Year), the values for the Cost of Service are returned incorrectly.
Example.
Semantic object: Billing Year Month = (yyyy-MM) returns correct values
Report variable: Substr([Billing Year Month;1;4) returns incorrect values
Can anyone please explain this problem?
Thanks,
Wannetta

Hi John,
The attribute of the Billing Year Month at the semantic level is a character type.
After reading your response, I realize that I may not have been clear regarding the problem.
The following formula does return the correct value in and of itself.
>=Substr([Billing Year Month];1;4
If I create a variable and then drag it onto my crosstab, it returns the correct value ONLY within the header.
When I drag the cost of service measure onto the crosstab; the header values remain the same but values in the body either disappear or the change to reflect incorrect values.
I thought one of the prime features of Webi was the ability of the Report Developer to create variables/formulas and use them in the headers to manipulate the semantic "measures" in the body (read: output) at the report level.
Is this a matter of semantic design or does Webi not possess this capability?
Or, is the issue entirely different?
Thanks!

Infoset and formula variable

Hello Gurus
I have couple of questions:
1) Using an Infoset, I want to do the following - Start with a Cube and do a left outer join with another ODS and in the same infoset do a left outer join between the Cube and an InfoObject. Is this possible?
2) I have a keyfigure which is an attribute of a InfoObject and hence it cannot be a navigational attribute. So to use that keyfigure in the query, we are using a formula variable and populating that keyfigure as a replacement path. However, the values for the keyfigure are being rounded off in the query. for e.g. if the value of the keyfigure in the master data attribute is 21.84, it is being displayed as 22.00. What setting could I be missing. I tried everything in the keyfigure setting?
Any help is appreciated.
Thanks,
Rishi

Ajay ,i would still repeat ,its 0FISCPER and not )posting period ,data model do not have posting period itself as infoobject
also for Sam,
it uses 0DATE and i use 0FISCPER so that link do not help ,moreover they use the dimension ID = DATE i cannot use that as am not counting the date fdiff or number of days here
thanks
can any one give me precise soln ,be great

Difference between New Formula and Formula Variable

Can any body explain what is the difference between New Formula and Formula Variable.
Thanks

Hi,
Formula:http://help.sap.com/saphelp_nw04/helpdata/en/d3/8057f830a911d4b2be0050dadfb23f/frameset.htm
Formula Variable:If you want use variables in the formulas of a form, you need to use formula variables. You can use formula variables only in form reports, and must define them in the form itself. They can be replaced in the same ways as text variables when you execute the report.

Formula Variables and their use

I have a scenario where I have a date selection using a variable.
I get from and to date defaulted to 1st day of the month and current date
Next, I created a formula variable to calculate the difference between these 2 dates.
I can't uses replacement path variable to calculate the difference becaue the dates are not part of the transaction data.
When ever I bring formual variable into a formual it gives an error
Terminate: Variable D1QDQC684JU76RD3FQ10GECZ9 (D1QDQC684JU76RD3FQ10GECZ9) does not exist or is incorrectly used D1QUMP50BGW24SQ9PQMZDSMD1 [A418(BRAIN)]
This error is not in the customer exit. This error happens in the query designer design phase during syntax checks.
Thanks for your help
Kartik

there was a problem in defining the variables, while u r opening your query, and if its getting terminated means, definition of the variable and its usage is wrong somewhere else.
Here is the step by step procedure for Formula variables:

How to extract list of object and formula used in variables as Excel for a particular Webi Report

Hi,
Is it possible to get the list of variables and objects, and variable formula used in a webi report extracted in excel or PDF in BO XI R3.1?
Thanks In Advance,
Shenbu

Hi Shenbaga,
You can try to get this information using the report engine sdks of BusinessObjects which is specific to webi reports.
Please refer to the link to download the dev guide and api referrence for XI 3.1
SAP BusinessObjects BI 3.x and Lower - Developer SDK Library
Refer to the Report Engine Java SDK dev guide and api referrence.
Go through the dev guide in detail and you would be able to use the report engine sdks as per your needs.
Additional Note: There have been changes in report engine sdks from XI 3.1 to BI 4.0 and you would not be able to get all the features available in XI 3.1 report engine sdks in BI 4.0.
Hope this helps.

Is variable offsets can be used for characteristics, text and formulas?

hi all,
can anyone let me know whether variable offsets can be used for characteristics, text and formulas.
if so cany one send me examples of using offsets to my email id [email protected]
regds
hari

You use offsets on dates (0CALMONTH, 0FISCYEAR, 0DAT and so on) and of course the corresponding texts.
If you have 0CALMONTH in your query and you want to do the same thing not only for the current month but for the past twelve months, they you just minus 1, 2....11,12 for each selections, and at the same time you can create text variable for the description of each month.
thanks.

Question about session variables and binding

Hi All,
I'm a newbie with Application Express. I've gone through several tutorials and a book, and now I'm actually getting started with apex. My first adventure is a tiny little form, where all you do is fill it out and it sends an email. Pretty simple.
And, i have it working just fine - but I have a question about something I don't quite understand. Basically, I am generating the email text in a page process. And some of the form fields work fine if i reference them as *:ACCT_NAME*, but some give me the dreaded "not all variables bound" error. For the ones that give me the error, I can reference them like V('ACCT_NAME').
So, as a newbie, I'm a little confused. When is it appropriate to use the V function, and when it is appropriate to use binding? Why would one of the fields work with binding but not another from the same form?
Thanks for any clarification you can offer,
Lisa

Lisa,
A bind variable is a place holder variable available in an environment.It is used quite frequently(outside Apex Context) in SQL and PLSQL scripts and especially in Dynamic SQL statements.Many times using a bind variable gives better performance. In the Apex environment,page items and many other variables related to the session are available as bind variables and hence their value can be referred in SQL,PLSQL contexts as :VARIABLE_NAME.
Now V() function is an apex specific function which returns the value of an apex session variable outside the apex environment. So as Machaan pointed out, it is used in
procedures and triggers that gets called from within an apex session. This is required since the bind variables themselves are not directly available in the SQL environment but their values from the corresponding session can be accessed by this apex built-in function.
The length of any Bind variable name is limited to 30 characters, this is a limitation inherited from Oracle SQL itself and hence session variables(page or application items) whose name has a length which exceeds 30 characters cannot be used as the :ITEM_NAME format. In such cases you would have to use the v() method again. This might be happening in your case.

Question about shared variables and report generator

I have a project with about 200-250 shared variables and at every 12 hours i want to make a report containing information about some boolean and double front panel variables linked to the shared variables... Now, i've tried with both the "Write Trace to SpreadSheet File" function from DSC->History and with different functions from NI Report Generation Toolkit. My problem is this: i would like to get my xls file to contain just the timestamps when my shared variable changed value. As it is, the number of rows in the file depends, obviously, on the sampling interval given as input. As an example, in 12 hours, my shared variable would change value maybe 5-6 times. Thus i would like my xls file to contain just 5-6 rows with those 5-6 changes. If i set the sampling interval to say, a matter of seconds, that would mean too much unneeded information in my xls file. Instead, if i set it to let's say 15 minutes, i would probably lose the moment the shared variable changed value. Is there a way for me to achieve my desired functionality with functions from DSC or Report Generation Toolkit? Thanks in advance, Sabin

Hi Mike and thanks for the reply. Actually, my first idea was exactly this: in an event case structure, whenever my variable changed value, i would retain the relevant data in an array and then at the 12 hour period write all of it in a report. However, my boss deeemed it memory unefficient and compelled me to use only one function. Thus my predicament... If you have more advice on this new info, i would be grateful... Cheers, sabin

A basic question about static variables and methods

What would be the effects if I declare lots of static variables and static methods in my class?
Would my program run faster?
Would the class take more memory spaces? (If so, how do I estimate an appropriate number of variabls and methods to be declared static?)
Thank you @_@

when you declare a static var the var isn't created for every instance of the class, it just "live" in the class
when you declare a static method is the same, so if you have:
class MyClass
static int myMethod()
//Method work
you dont need to have a instance of the class to call myMethod, you can do such things like this.
int value = Myclass.myMethod();
if myMethod isn't static you can't do this.. so, if
class MyClass
int myMethod()
//Method work
you CAN'T call
int value = MyClass.myMethod();
instead, you have to write
MyClass m;
m = new MyClass();
value = m.myMethod();

How to find colums in CLOB variable and get this colums value to update col

Question
How to find colums in CLOB variable and get this colums value to update colum of oracle database table
How my work will go
Step-1 - I am creating XML FIle which is based on code that we discused before-
Its developing xml file with data in <...inputelement> as u can see in my xml but in <..output> Element of xml its just have all column for exampe <itemoutput>
<FLD NM = "ABC"> 0 </FLD>
<FLD NM = "XYZ:> </FLD> --- for varchar2
</itemoutput>
In 1st stage i am just generating <..INPUT> with its colums and real value from database and <..output> elements will go zero value but with colums name.
Note. I create temp table will all COLUMN which u can see in both in <..ITEMINPUT> and <..ITEMOUTPUT>
Step2.. After Generaing my xml i want to convert my xml data into CLOB not in a file. so clob will go to the VENDOR
STEP3.
I will Recieved again xml data in CLOB from the vendo in <.OUTPUT> ELEMents
for example
I send this format
<itemoutput>
<FLD NM = "ABC"> 0 </FLD>
<FLD NM = "XYZ:> </FLD> --- for varchar2
</itemoutput>
And i will receive it
<itemoutput>
<FLD NM = "ABC VALUE"> 2 </FLD>
<FLD NM = "XYZ TYPE:> SUV</FLD> --- for varchar2
</itemoutput>
So will take this output valu from xml clob and will update my staging table .
Which have the same colum name as its look in xml clob.
Step- 4. I will take this value from staging table and update my original oracle database table. which i send you before.
But u leave this step becaue you dont know the staging table colum maping with original table.
I think now you understand
Please feed back
monriz

here is my xml..
I want to extract <..output> elements which enclosed with " " and its values from this xml file. please any body have any idea. please tell me
Thanks

Using Shared Variables and Initialize Front Panel Binding (to PSP)

Hi,
I use LV DSC RT 8.2.1
I have a Vacuum System That includes signals from - Pumps failure, Valves status, Vacuum gauge, start Pump ...
Each signal is read by a FieldPoint.
All the relevant FieldPoint Channels are read by the Server (a computer in the Ethernet Network) and published to the network in the form of Shared Variables.
I have a client VI that is reading the Shared Variables published by the Server using Front Panel Binding.
Problem :
Some of the Bindings are in the mode 'Write &Read' and that causes some initialization problems.
For example - Valve #1 is Open, and then a User start running the Client VI, (the Valve #1 Status mode is 'Write & Read")
if in the VI the status of Valve #1 is closed (before running it) then the Valve status is changing to Closed.
I want the Client VI to first read the Physical status of the instrument and then to change the Value if the User changes it.
But that's seems to be a problem when using Front Panel Binding... (is it?)
I know I can Deploy a lvlib in the Client Side and Item Bind to the Shared Variables or Use DataSocket.
(Is DataSocket is a Reliable method when connecting to Shared Variables? What are the disadvantages when using DataSocket?)
What is recommended by those of you that are experienced or by NI ?
Sincerely Yours,
Amitai Abramson.

The issue that you are seeing by having "Write & Read" bound items on both the server and client side is essentially a race condition, you don't know which one is being read/written at what time. To resolve this issue I would take a look at some of the documents below.
Using a Local, Global, or Shared Variable in Parallel Loops Can Cause Race Conditions
Using Local and Global Variables Carefully
Tutorial: Local Variable, Global Variable, and Race Conditions
Locking a Shared Resource or Variable in LabVIEW Using Semaphores
You mentioned not wanting to have two sets of shared variables (one on each side), but this is a great method to resovle this issue, that, or you can develope some sort of hand shaking to prevent these race conditions.
I would suggest that in the future when using these forums you try to ask only one question per thread and make it more concise. It's hard to tackle multiple questions and such broad questions as "I want to know all the ways that I can connect to Shared Variables, and I want to know the advantages and disadvantages." I suggest this because we want you to get your questions answered and more concise questions will result in quicker and better answers.

Basic behavior - compile vs. save, application freezes and other questions

Hi all,
I've just recently moved from MS SQL to Oracle and found Oracle SQL Developer the only more or less working application to access the database and write scripts. Still, there are some issues which are beyond me in this application. So what I'd need to know:
1) When I open a package and edit it, what is the difference between hitting CTRL+S (save) and Compile? I just need to change the code, not run the damn script. Run and Debug I suppose would execute the whole package.
2) When I save a package, why does the application freeze? I have no idea what it is doing, but when I kill it the code is not changed.
3) When I connect to packages of a different user why cannot it export the ddl / source code of the whole package?
4) When I am inactive for some time, is there some normal way to reconnect to the connection other than disconnect + connect, which closes all windows I have open on the connection?
5) Why does drag + drop a table name to SQL worksheet sometimes offer me to create a script and sometimes ignores me completely?
6) Is there any way to convince the popups with table/column names to work also with variables and/or to show also data types of columns? Incidentally, is there a way to make it work all the time and not just during favorable moon phases?
Thank you ever so much for answering any but preferably all questions.

1. None
2. Might be a lock - check the Enterprise Manager
3. What is connecting to packages? How are you trying that export?
4. Go vote on http://htmldb.oracle.com/pls/otn/f?p=42626:39:1538555050886906::NO::P39_ID:10421 to add weight for a real reconnect option
5. Script? You mean insert/update/select, right?
6. You mean the completion insight? Note you can force it to show with CTRL-space. If that doesn't work you'll have to be more specific.
Regards,
K.

RH10 variable and build tag source file names

I'm using RH10 and outputting to WebHelp. My company requires that I archive project source files to our CVS via Eclipse. I am not using RoboSource_Control and must use the company's development resources for archiving.
Since archiving the initial project, I have been uploading only source files with modified dates.
However, I have discovered that the files I thought were storing user variables and build tags are not the correct files to archive. Since I am uploading all files with a newer date and that's not working, I need to know the user variable source file name and the build tag source file name that stores the currently defined variables and build tags.
I have already tried the WebHelp forum and was directed to this forum to pose the question because I'm looking for source file information instead of output file information.
Thanks for your help!

Yes, Eclipse does work that way. However, we do not use our development directory as the local Eclipse repository. I need to move changed files to the local repository (stores all source files in the project) so that Eclipse can upload changes to the server. Yes, this is planned redundancy.
That said, it is not acceptable to spend the time copying all files in the large projects from the work folder to the local repository. I simply need to know which individual files to copy that include the currently defined variables and build tags. Note, we do not copy the SSL folder output files to our local source file repository, or other associated reference files that are not actually project source files.
Can you find someone who knows which files I need?
Thanks,
karen
