How to use Variable in message mapping

Hi Experts,
I have some problem using variable in message mapping.
In one message mapping, since a block of logic is repeated for several fields, then i tried to use a variable instead.
the repeated logic is: first if condition, then use a udf to form a queue which will be suppressed by its father node.
i tried to assign the result queue to a variable after the UDF execution. (this variable is created after the father node)
I am wondering is there any restriction of using variable?
Can we assign the whole queue to a variable?
Can we use UDF during the process of assigning value to variable?
thanks in advance.

I dont think you can assign a queue to a variable,I am not 100% sure, . and there is no restriction to useing a Zvariable, only u can use it after you declare at some parent level.
Yes you can use a UDF in the process of assigning to a Zvariable.

How to use error table in mapping level?

Hi all
Any one please tell me how to use error table in mapping level or how to handle the errors in mapping.
I am creating one error table in oracle but i dont know how to use it in mapping.
Thanks in advance.
Kumar

Hi Kumar,
You need to use Error Table along with the Data Rule .
Error tables are used with Logical error handlers (Data Rules). Detailed description on using data rules is explained in the following document
http://www.oracle.com/technology/products/warehouse/pdf/OWB10gR2_ETLandBusinessRules.pdf
In a nut shell usage of error tables is as follows.
1. Create a data rule associate it with a table (Target table or table in which you load data).
2. Use the table in a mapping as target table.
3. Deploy the table and mapping.
Now in the target schema one more table will be created with the name <target table name>_ERR. When a mapping is executed the data which violates the data rule gets into this error table.
The following has to be done to have error table name of customers choice.
1. Right click on the table and click configure.
2. Give the table name in "shadow table name" section.
3. Deploy the table.
4. Use this table in a mapping. Now in the mapping on this table properties in "Error Table Name" section the name of the table specified in "shadow table name" will be populated.
Thanks,
Sutirtha

How to do this with message mapping in PI ?

Hi All,
Field 1 = 100 characters having values in first fifty characters and last 50 characters blank . I need to remove all the first 50 characters with blank and pass 100 blank characters .How to do this with message mapping
Thanks

Adding to that, since usually a tab = 8 spaces. What you can do is to open notepad, press tab 4 times. Copy it and paste 3 times, afterwards press space 4 more times and you get 100 spaces.

yes, my Data source is SAP BW, and connected to BOE via SAP INT KIT.
It's too bad that SAP doesn't support so simple requirement.

so there are possibility to solve my problem.
would you give me the logic of user exit? which part I should create the user exit
I'm quiet familiar with user exit in BW

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.

Bhavesh

Virtual directory mapping: how to use variable in local-path element

Hi all
We are using a virtual-directory-mapping declaration in the deployment descriptor
for our web application to load jsp'a and other files from the file system.
This declaration looks like this:
<virtual-directory-mapping>
<local-path>c:/views/jsp</local-path>
<url-pattern>*.jsp</url-pattern>
</virtual-directory-mapping>
Here is my question:
Is there a possibility to use a variable in the local-path element? Something
like:
<virtual-directory-mapping>
<local-path>%PATH_TO_JSP%</local-path>
<url-pattern>*.jsp</url-pattern>
</virtual-directory-mapping>
If yes, how does it look like? My example above didn't work.
If no, is there another way to do that?
Thanks in advance
