How to use substitution variable in case of dim build

Hi all,
Lets say I have 3 sub vars - Prevmonth, prevmonth-1, prevmonth-2. These will change every quarter.
I want to build a cube which will have which will have only the above 3 months in the Fiscal dimension. This will be used once at the end of quarter.
How do I refer substitution variables in case of dim build rule files? I want automate the process. We have SQL dim build for other dims, only this dim can be built from flat file also.
Or is there any other way to achieve this apart from using sub vars? I can try store the 3 variables in a table and then use them to build the cube, but want to see if we can avoid creating one more interface.
Thanks.

Actually using the values of subvars to build a dimension (which I believe is what you want) is a fun problem. Here's an (Oracle) example that would do that, without requiring any additional table or flat file:
    SELECT 'FiscalPeriod' AS Parent,
           CASE Level
              WHEN 1 THEN '&CurrMonth'
              WHEN 2 THEN '&PrevMonth'
              WHEN 3 THEN '&PrevMonthMinusOne'
           END AS Child
      FROM Dual
CONNECT BY Level <= 3
Here's how it looks in the load rule SQL dialog, and the data prep editor:
It's fun because I've never thought about it before, but I don't actually recommend this - if you have other ETL going on in SQL I'd generate the values in a table / view there, and have a script that both updates the subvars and builds the dimension direct from that.

How to use substitution variables in Microsoft Word using Hyperion Smart view

Can we use Substitution Variables in copy data points and refresh in Microsoft Word? I tried it and it does not work dynamically (copy data points only copies what was in excel cell at that point). It only copies the static value of that variable from that cell. I want to use it dynamically in Word so that if I change the value of that variable in Essbase, it is updated in Word upon refresh. Any idea??
We need this feature for reporting in microsoft word and keep using the data points every year (instead of copying the cells from excel over again)
Any help/suggestion is appreciated.
Thanks

you can't use substitution variables with copy data points. I had tried a while ago (post 111.1.2.1.102) and it wouldn't work. I checked with Oracle development and they said it I not available

How to use substitution variable in sql

Hai All
I have two tables Rgpmain and Rgpitem the fields are

i need to to four values in sub function and i will give one value and i need the result of one variable
The qurey will like this
Select * from rgpmain m, rgpitem i where unitid=1 and periodid=14 and m.unitid=i. unitid and m.periodid= i.periodid and m.docno = i.docno and vendcode ='&p_vendcode'
Or
m.unitid=i. unitid and m.periodid= i.periodid and m.docno = i.docno and vendname like '&p_vendname%'
Or
m.unitid=i. unitid and m.periodid= i.periodid and m.docno = i.docno and partname like '&p_partname%'
or
m.unitid=i. unitid and m.periodid= i.periodid and m.docno = i.docno and partno ='&p_partno'
This is my query
And while i am executing there are four options showing to enter..
My need is i need enter only one field Ie vendcode and execute the vendcode like ABC01 then i need the only
the result that belong to vendcode ABC01 but my query giving all the rows

How to use substitution variables in sqlplus activity of process flow

I have a process flow that does nothing more than create a couple of packages that I cannot successfully deploy from OWB. A workaround, not something that I want to do, but currently there is not much time to adjust the packages so they can be deployed from OWB.
I can successfully create the packages from files that are present in a directory on the server. But the location (directory) is not the same in all cases (OTAP). So I thought to use an input parameter to the process flow (named TELLINGEN) and use that in the sqlplus activity.
I have created the parameter START_PATH with a default value.
I have added an sqlplus activity and placed the following into the PARAMETER_LIST variable of the activity:
?${Target.ConnectString}?@${TELLINGEN.START_PATH}/npl_dbug.pkg?
When I run the process flow I see the following in the output:
SQL*Plus: Release 10.2.0.3.0 - Production on Tue Mar 18 18:10:14 2008
Copyright (c) 1982, 2006, Oracle. All Rights Reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SP2-0310: unable to open file "${TELLINGEN.START_PATH}/npl_dbug.pkg"
SQL> SQL> Disconnected from Oracle Database 10g Enterprise Edition Release
10.2.0.3.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
It obviously connects to sqlplus but then cannot find the file. Presumably because the variable has not been substituted.
How can I persuade the activity to substitute the variable?
Kind regards,
Eric.

Have been reading around a bit and found the (a) solution:
I placed the following in PARAMETERLIST:
?${Target.ConnectString}?@${Working.RootPath}/base64.sql?
And it turns out ${Working.RootPath} is pointing to the location you can provide under the configure for the sqlplus activity in the process flow. Just as you have to provide the target destination as indicated here: Re: SQLPLUS Activity in Process Flow
From the documentation it was not immediately clear to me where Working.RootPath was pointing to.

How can i use substitution variable

Hai All
This is my sql statement
SELECT (TO_DATE(TO_CHAR(Intime,'DD-MON-YYYY')||' '||
TO_CHAR(0815,'0000'),'DD-MON-YYYY HH24:MI')-intime) * 24*60
from dail_att where to_char(intime,'hh24mi') between 0700 and 0815 ;
Here my table name called Dailyattendance
Intime field is declared as Date Type
So now i have hardcoded 0815 and now my intime is subtracted from this time so i can calculate the employee
coming late so how can i use substitution variable here to give the value at run time
Ie i need to give 0815 instead or any other time at runtime
Thanks In advance
Srikkanth.M

Where exactly are you planing to use it? Is sqlplus or at any other front end?
One way is to use below given SQL
SELECT   ( TO_DATE (   TO_CHAR (intime, 'DD-MON-YYYY')
                     || ' '
                     || TO_CHAR (:TIME_VAR, '0000'),
                     'DD-MON-YYYY HH24:MI'
          - intime
       * 24
       * 60
FROM dail_att
WHERE TO_CHAR (intime, 'hh24mi') BETWEEN 0700 AND 0815;*009*

Conditional suppression using substitution variable in Hyperion financial r

Hi all,
Is there a way that I can suppress a column using substitution variable in hyperion financial reporting?
For eg, i want to suppress the column if the value of the substitution variable curr_mnth = jun.
Is there a way to do this? In conditional suprression dialog box, I dont find this option.
Please suggest.
Your response is appreciated.
Thanks,
Sirisha.

Hi Sirisha
In my earlier reply I think I may have mislead you as I thought that you could set the member name equal to that in a row/column and I've managed to get into a HFR studio session this morning and realised that the conditional suppression only allows you to suppress where member name = 'XXX' (specific text) so that doesn;t meet your requirement.
Different people will have different ways of achieving what you want and everyones requirements are different. If it helps my preferred way of conditionally suppressing periodic data (for Planning/Essbase) is to add a dynamic calc account member called 'TP-Index' into the database, set up a formula so that each period returns a numeric value from 1 to 12 to match the fiscal/calendar year as required.
Then in reporting bring the account and period dimensions into rows/columns so that you are able to retrieve data for the TP-Index account and the period as defined in your substitution variable. You can then choose how the suppression works based on a numeric value, commonly you may want to suppress if greater than, e.g. you have a multi-period report where your actual data is to June so you want to suppress everything from July onwards.
I'm sure that a similar thing could be achieved in HFM as well if that is your underlying system instead of Essbase.
Does that help?

Can we use Substitution variables in MAXL?

Hi,
Can we use substitution variables in MAXL script?
I have to run this MAXL command for clearing a slice of ASO cube on V11.1.1.3.
alter database Apname.DBname clear data in region 'CrossJoin({[2009]},{[Dec]})';
I am planning to use Current_year & Current_month variables instead of hardcoding 2009 & Dec as I have to use this everymonth to clear the current months data.
If it is allowed, what is the syntax?
Is there any alternative apart from substitution variables?
Appreciate your thoughts.
Thanks,
-Ethan.

You would just use ampersand and the variable name instead of the hard coding e.g. &yearVar &periodVar.
Not tried it on aso clears but in theory it should work as ...'CrossJoin({&yearVar},{&periodVar})';
just change yearVar and periodVar for your substitution variable names.

How to use the variables used in the message mapping

Hi ,
In the message mapping we can declare variables in the JAVA section , these variables could be used across the mapping .
I have tried using it but I am unable to retrieve the values assigned to the variables in one UDF into the another UDF .
Please guide me how to use the variables declared in the JAVA section in the message mapping .
Thanks
Anita Yadav

Anita,
I have worked on the Global variables and i found no issues. Make sure that the variable is declared in the Declaration Section and then initlaized in the Initialization section.
If you declare a variable in the Declaration Section ,
int i;
then in any udf you can use if directly. No need to re declare the variable in the UDF. If you do this, then it becomes a local variable.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

Using Substitution Variable in Web forms

Hi,
I'm trying to use substitution variable in a planning web form &CurYr in the Column, after creating the form when I save it and try to open the form it says the substitution variable required for this calculation is undefined .Variable : &CurYr.It should be defined as I'm able to see it and select it for the column/row. Any kind of help is appreciated.
Thanks
Vinil

You usually get this error message if you are trying to assign a value from a sub var to a member that does not exist.
e.g. trying to put FY08 which is a year member against a period dimension
or trying to use a sub var of FY09 which does not yet exist in the essbase, so say you added a new year in planning FY09 and used the sub var in the form but have not refreshed the database then it would fail because the year would not have been pushed down to essbase yet.
or the value of the subvar does not match a member name exactly
or using a sub var name that does not exist in essbase, e.g. using &nextYear but the sub var has not been created in essbase.
You can definitely use subsitution variables in columns in the version you are using and prior version.
