Is it possible to use parameters as variables in templates?

Hi there,
When you see a statement like the following in your template:
<$defaultPageTitle=lc("wwNgEditFolder")$>
Is there any way to replace lc("wwNgEditFolder") for something more dynamic? For instance, if I replaced the above with something like this:
<$defaultPageTitle=myURLVariable$>
and then use the url as follows:
.../idc/idcplg?IdcService=MY_SERVICE&myURLVariable=mytitle
Would that work? or what else can I do to dynamically give values to my page.
Thanks!

Any parameter you pass to a Service in the QueryString will be available to you as a variable in the template.

Possible to use parameters in MDX Studio?

Is it possible to use parameters in MDX Studio? I've tried using SSRS2008 for query design but...
SSRS2008 query designer complains that parameters do not exist when they quite obviously do ( in the report)
LaCie drives. Failing when you need them most."La" meaning "Terrible", "Cie" meaning "customer service"

You can declare parameters in XMLA format after the MDX query - see examples in this post:

Is it possible to use Global class variable in a BAdi

Hello Experts,
I have a requirement wherein ,
I need the Reference of the Class Object to be used in a BAdi. The class object is defined as a global variable.
By any means can I use the reference variable inside the BAdi.
thanks

Hi Hari,
U can access any objects or variables in BADI only if they are used as parameters in it.
So please check whether that global object is declared as parameters in the corresponding BADI.
If so, you can surely use it.
Reward points if this is useful.

Is it possible to use a Shared Variable within a Chart?

I have a shared variable between a container report and a subreport called {@ResponseCount}:
whileprintingrecords;
shared numbervar Responses:= DistinctCount ({Survey_Response.RecipID})
I placed the variable in the report footer and the value is passing correctly. I would like to use this shared value in a chart; however, it is not even listed in the Chart Expert as an available field. I was placing the chart in Report Footer b.
I have also tried moving the variable value to the Report Header and placing the chart in the Report Footer, with the same result.
I tried changing the variable to a global variable, thinking that I was using the incorrect scope, but that passed a zero value instead.
Any suggestions would be welcome. Thank you.

Thank you for the response. Though I almost gave up on this, I did find a way to access the shared variable after all. I created a formula that simply called the variable formula. For this example, I was using a shared variable to pull a value from my container report into my sub report for use in a chart.
In my container report I created the shared variable {@Get_Responses}:
whileprintingrecords;
shared numbervar Responses:= DistinctCount ({Survey_Response.RecipID})
In my sub report I created the formula to call the above variable {@Fetch_Responses}
whileprintingrecords;
shared numbervar Responses;
Then, again in my sub report, I created a second formula to call the above formula {@ResponsesForChart}
{@Fetch_Responses}
This last formula was then available for use in the chart I needed to create.

Is it possible to use a ODI variable in a procedure

I am trying to call an external java program from the operating system (MS-DOS) using a procedure. This is possible using the os.system("<command>") syntax - declaring a procedure to use Jython. However, I want to be able to pass two ODI variables to the java program. I do not seem able to do this, is it possible ?
I also tried calling the OS command from within a package - but again cannot get the OS command to pass the variables.
I would appreciate any help on this.

Thanks for your response.
I am still unable to do this.
Problem is the procedure is "Jython" and it does not know what the ODI variables are.
I basically have two variables source and target which need to be passed to a java procedure.
So I created two VARIABLES in ODI - source and target.
I then have a procedure with the command;
import os
import sys
cmd = "java ConvFile"
rc = os.system(cmd)
when this runs it does not pass the variables.
if you have
import os
import sys
cmd = "java ConvFile"+#Tax_Updates.SourceFile+#Tax_Updates.TargetFile
rc = os.system(cmd)
then it does not know what #Tax_Updates.SourceFile and #Tax_Updates.TargetFile are and so just passes them as strings.
If you still think it is possible or anyone esle knows can you elaborate a little on the solution.
Thanks

Is it possible to use a form variable (in memory) as input to render pdf?

Hi,
I understand that the render to PDF service takes URI as input, but what if I have a xdp form modified and stored in memory, and would like to use that to render PDF, how can this be done?
Thakns in advance.

Hi Jasmine,
Thanks for the tip. So, is this what I need to do?
I have an xdp form in the repository, and xml data I generate from a custom component.
1. render the pdf form (merge xdp (no data) with xml data)
2. convert pdf back to xdp (this xdp now includes data) and stored as a document variable in memory
3. manipulate the xdp (via custom component)
4. render the pdf form by passing the xdp (from step 3) in a document variable type as part of the data parameter, leaving URL blank.
5. write pdf to disk
This would work right? Is there another way?
Thanks in advance.

Using a java variable in jsp-Reports?

Hello everyone,
is it possible to use a java variable in the xml-definition of a report? Something like
<%@ taglib uri="/WEB-INF/lib/reports_tld.jar" prefix="rw" %>
<% String someSqlStatement="select * from emp"; %>
<rw:report id="myReport">
<rw:objects id="myObjects">
<report DTDVersion="9000010" name="myReport">
<data>
<dataSource name="Q_1">
<select>
<![CDATA[
<%= someSQLStatement %>
]]>
</select>
It won't work that way (as the string is not evaluated and inserted into the definition, but how could it be done? Would be great to modify the report programatically that way? Any ideas?
TIA,
Marcel Jantz

To pass values to Reports, you should use the "parameters" attribute in the <rw:report> tag. In the above case you would have:
<% String myParameters="p_someSqlStatement=select%20*%20from%20emp"; %>
<rw:report id="myReport" parameters="<%= myParameters %>">
<rw:objects id="myObjects">
<report DTDVersion="9000010" name="myReport">
<data>
<dataSource name="Q_1">
<select>
<![CDATA[ &p_someSqlStatement ]]>
</select>
The body of the <rw:objects> tag isn't evaluated since the Reports Builder needs to be able to open and load the <rw:objects> tag. As the Reports builder doesn't run the .jsp on open, it only parses it, the <rw:objects> tag can't have values that need to be evaluated.

BC4J List Validation from SQL Query, using parameters?

When adding validation to a business component, one of the options for the list validation rule is 'Query Result'.
is it possible to use parameters??. e.g. for a student type registration application
validation on studentEntry that the course is availabe for the term entered would be like :-
Select course from courseCat where term = :pterm
where :pterm is the current term that the student has entered, this exists on the current studentEntry row.
how would I code the parameter in the select statement in 'edit validation rule' screen?

how would I code the parameter in the select statement in 'edit validation rule' screen? This is currently not available on the built in validators. However you can create a custom-validation rule and perform such bind params and execute queries. We do have plans to support named paramters in queries that will allow us to enable this feature on validators as well.

Using BASH environment variables in xCode build configuration

Hi All,
Is it possible to use BASH environment variables (exported from /etc/profile, for example) in xcode build settings?
Specifically, I am exporting a "BOOST_HOME" variable, and would like to referencing this variable in "User Header Search Path", but the obvious $BOOST_HOME doesn't seem to work?
Thanks,

I don't know much about XCode -- but to set environment variables for GUI applications you need to edit ~/.MacOSX/environment.plist. There's a description here:
http://wiki.lyx.org/Mac/Environment
After editing that file I believe you have to logout and back in for the changes to take effect.
I swear I saw a GUI app to help edit that file, but I can't find it now...

Use of Input Variables in SQL-Queries Sometimes Not Possible

Only in simple SELECT-statements the use of input variables ([%0], [%1], etc.) work without problems.
In more complex queries the use of these variables is not possible (e.g. SELECT-statements with sub-queries, sometimes when UNION is used - but I couldn't find any general rule when the problems will arise; sometimes two different queries with the same query-structure behave in different ways when these variables are used).
In these cases the query is not executed - not even the input-window to enter values into the input variables is displayed. The query stops with some strange error-messages in the status line. These error-messages doesn't have any relation to the actual query - sometimes it refers to field-names never used in the query or refers to syntax error which do not exist.
If the input variables are replaced by constant values there are no problems so there can't be any syntax errors - the only difference is the presence or absence of input variables.
Example:
provided that the queries have a certain complexity
SELECT ...
FROM ... OINV Tx ...
WHERE ... Tx.DocDate >= [%0] ...
does not work,
SELECT ...
FROM ... OINV Tx ...
WHERE ... Tx.DocDate >= '1.1.2007' ...
works!
Does anybody have run into the same problem and now if it is a bug of SAP-BO or an error on behalf of the user? Does anybody know a way to correct the problem?
Thanks in advance!
Frank
By the way: Are there any rules where exactly input variables can be used in a query?
Only in SELECT-statements? Where there exactly?
In statements outside of SELECT?

The following query is an example for how to define variables in long
queries rather than using "Fixed Declares".
You need to use exactly the same template as follows, do not delete
"comments" from this query.
The only changes you need to do :
1. In the first and in the fifth rows you need to select the table to which you would like to relate the variable e.g. in this example, the variable is related to the table VPM1 - 'Payments to Vendors - Rows'.
2. In the fourth and in the eighth rows you need to select the field to which you would like to define the variables e.g. in this example, the variable is the field 'DueDate'.
/SELECT FROM [dbo].[VPM1] T0/
declare @fromdate as datetime
/* WHERE */
set @fromdate = /* T0.DueDate */ '[%0]'
/SELECT FROM [dbo].[VPM1] T1/
declare @tilldate as datetime
/* WHERE */
set @tilldate = /* T0.DueDate */ '[%1]'
select OVPM.docnum, VPM1.dueDate,VPM1.CheckNum, VPM1.Branch,
VPM1.BankCode, VPM1.CheckSum, OVPM.CardName,

Solution
In such cases you need to put in an SQL remark statement a reference field in the DB for the Survey Variable (any field).
For Example: (to make the above query work)
Declare @Num as numeric(2)
Set @Num = /* T0.DocNum */ [%0]
Select T0.DocNum
From ORDR T0
Where docnum = @Num

Is it possible to use a case statement when joining different tables based on input parameters?

Hi,
I have a scenario where my stored procedure takes 5 parameters and the users can pass NULL or some value to these parameters and based on the parameters, I need to pull data from various tables.
Is it possible to use a case statement in the join, similar the one in the below example. I'm getting error when I use the below type of statement.
select a.*
from a
case
when parameter1=1 then
inner join a on a.id = b.id
when parameter1=2 then
inner join a on a.id = c.id
end;
Please let me know, if this type of statement works, and if it works will it create any performance issues?. If the above doesn't work, could you please give me some alternate solutions?
Thanks.

Here's a technique for joining A to B or C depending on the input parameters. In theory, you are joining to both tables but the execution plan includes filters to skip whichever join is not appropriate. The drawback is that you have to do outer joins, not inner ones.
CREATE TABLE A AS SELECT LEVEL ak FROM dual CONNECT BY LEVEL <= 100;
CREATE TABLE b AS SELECT ak, bk
FROM A, (SELECT LEVEL bk FROM dual CONNECT BY LEVEL <= 10);
CREATE TABLE c(ak, ck) AS SELECT ak, bk*10 FROM b;
variable p1 NUMBER;
variable p2 NUMBER;
exec :p1 := 1;
exec :p2 := 20;
SELECT /*+ gather_plan_statistics */ A.ak, nvl(b.bk, c.ck) otherk FROM A
LEFT JOIN b ON A.ak = b.ak AND :p1 IS NOT NULL AND b.bk = :p1
LEFT JOIN c ON A.ak = c.ak AND :p1 is null and :p2 IS NOT NULL and c.ck = :p2
WHERE A.ak <= 9;

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

Possible to use local variables in Calculation Manager

Hi,
I'm using calculation manager in EPMA for the first time. Have not found any function for using "local variables", i.e. variables that can be used for fixing on the current members a user has selected in a form. Do someone know if it is possible to use that functionality in calculation manager? And in that case, how do I find it?
Thanks!
Regards
Mats

Hi,
I guess you are referring to local variables in Essbase Administration Console. When you are in calculation manager (System View), you can go to Tools->Variables. There you can create variables at application, database (global) or business rule level (local variable). You can use these in Business rules by placing the name in curly bracket {...}.
The usage of the variables in the forms is the same as before.
If however, what you meant to say by local variables is substitution variables, yes you can use them in Calc manager the same way you use in calc script.
Cheers,
Alp
