Using variables in transform process

Using file adapter to read multiple rows into the database. Its a basic transformation with a one to one match, e.g. what's on the left exist on the right.
The issue is that I want to uniquely identify each file process with an ID. Therefore what I have done is set up a sequence which will be used as a batch ID. I assign this to a variable before I transform the file definition to the database definition.
What I would like to do is assign this variable to a field in my database as a kind of dynamic constant. I don't seem to be able to use the getVariableData in the options. I want this ID to be loaded on every line without incrementing.
Does anyone know if it is possible to use variables within the transformation.
cheers

Using variables in Page processing

I want to use variables (items) in
Page processing - process - reset pagination for page(s) (PageID,PageID,PageID)
and
Page processing - Branches - Branch to page / URL - URL
Is this possible, and if so How
Fred.

scott,
On the places I mentioned I have tried to use references like &ITEM. and #ITEM# but they don't work.
Where can I find documentation about where I can use which references.

Using variables with transform.colorTransform

I have declared a handful of new colors like this:
var colTransNameNumber:ColorTransform = new ColorTransform();
colTransNameNumber.color = 0x77060A and so on.
The Name and Number are coming from variables in the query
string but when I try to call the colors by doing "colTrans" + name
+ num, I get the Type Coercion failed: cannot convert
"colTransNameNumber" to flash.geom.ColorTransform. error. It
doesn't like the string being passed to it. Does anyone know how to
create this in the correct format?
thanks.

Have you tested if you can read the value of a variable from Captivate into your widget by using the MovieClip(root).varX code?
I think that you are better off with using the Widget APIs approach to variable handling - it's usually defined as mainmov.varX and you can check the Certificate AS3 FLA to see how it works.
EDIT: Just saw Jims answer - he is an AS3 wizz so if he says you done it correctly then that's most likely true ;o)

Trying to use the transform process activity - flow with 2 invokes

I want to transform incoming data with a transform "Process Activity" and write this transformed data out to two files. What I have tried to do is to transform the incoming data and then send the transformed variable into a flow with two invoke "Process Activities" which in turn use two "File Adapter" services to write to two separate output files. When I attempt to deploy this I get a complaint that I cannot use a single variable to feed both invoke "Process Activities" because of name space conflicts. Does anyone know how I could do this transformation without having to write a transformation for each invoke? It seems like it should be possible to simply write one transformation for multiple invoke operations. However, perhaps there is a completely different way to do what I am trying to do. I am fairly new to using BPEL and the Oracle SOA Suite. Thanks much!

Here is the error message when I try to do what you suggested in your last post:
Error(83):
[Error ORABPEL-10035]: wrong messageType
[Description]: in line 83 of "C:\SOADEMO\DataTransMultVETRO\bpel\DataTransMultVETRO.bpel", messageType "{http://xmlns.oracle.com/pcbpel/adapter/file/FileWrite1/}Employee2_msg" of variable "Invoke_FileWrite1_InputVariable" does not match the expected messageType "{http://xmlns.oracle.com/pcbpel/adapter/file/FileWrite2/}Employee2_msg" in <invoke>.
[Potential fix]: make sure the correct variable is used in invoke.
I believe it is a problem with name spaces. I could change the name space prefixes, but that causes other errors. I am using JDeveloper to create this BPEL process flow using their predefined graphic "Process Activities" and "Services". FYI, I haven't gotten too much into writing the xml from scratch as I would think that the tool should be flexible enough to create this simple process flow.

To use the transformation process I hear you have to code using OOP, True?

I've heard that to use the transformation process all update rules, routines must be writtend with OOP and you can't use the older coding method. Is this true

Prefferably Yes Routines hav to be migrated accordingly to OO ABAP.

How to Import xsd and use it in transformation for mapping

I have constructed an xsd and want to use it in BPEL Process.I imported the xsd into development.But I am unable to understand how to further proceed.Can anybody suggest me how to import xsd and use it as it has to be defined in wsdl before using right.Is there any way we can use xsd?

Hi',
See in a BPEL (web service) we use XSD to define its input and output, inside this BPEL process you have input and output variable.
Now inside the transform you can use this variables to transform data, there can be many other variables too, when you try to invoke
some other BPEL process you again create new input and output variable.
Inside a transform activity you have a source and a target there you can decide where all the input is coming from you could have
one or many variables in source and only 1 in target, this is how your variables (or XSD) can go inside the transform, inside the transform.xsl
view you can right click on the source side(left) and include any new variable there.

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,
LaVIEWan
Solved!
Go to Solution.

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.

FTPs connection error:When using Variable substitution for Directory path

Hi
I am transferring data from BI to xml file via PI: Here a Client proxy from BI sends the data to PI and the PI FTPs the XML file to a remote location. For FTP I am using FTPs SSL connection.
It was working fine untill I used Variable susbstitution to determine Directory path dynamically. I am using this because different xml files are intended to goto the different locations.
I did the variable substitution like this:
Target Message Structure:
---> Target Directory: %var1%
<?xml version="1.0" encoding="UTF-8" ?>
<MT_BI_EXTRACT_FILE>
<Header>
<Directory>/Customer</Directory>
</Header>
<Detail>
</Detail>
</MT_BI_EXTRACT_FILE>
And in the variable substitution I am doing it this way
payload:MT_BI_EXTRACT_FILE,1,Header,1,Directory,1
And the error I am getting is:
Attempt to process file failed with Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake failure

Does anybody have some Idea of this ??
Regards
Naina

Hi,
I guess the problem is not with Variable Substitution..
Error when getting an FTP connection from connection pool:
So its a connection problem..
Also check the option Disable Security check and try again...
Try to check again if the interface is executing properly without Variable substitution and let us know..

Used variable substitution to substiture the field 'date' in file name

Hi gurus
I have used variable substitution to substiture the field 'date' (dd/MM/yyyy/hh/mm/ss) in the file name so when empty payload (a valid xml ) is generated by Message mapping then the communication channel is failing by showing the following error
File processing failed with com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during
variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: The following variable was not found in the message payload
: date
As of now the business is not getting effected as the business scenarion needs only customer master data at the reciever side But when ever there is no custmer master data in the sourse side the message mapping is generating an empty payload and the communication channel is failing ( so it is an internal issue and is there any way which could solve the both (ie the business must not get effected and as well the communication channel must not fail)
any coments on this will be higly apreciated
thanks and regards
sandeep

Hi Sandeep -
Yes If you use the Variable substitution from the payload , that perticular field has to be generated in the target structure.
To handle this You can do the following:
Sourcefield --->exists -> IfThenElse-->TargetField
Where     SourceField>exists(node function)-> If
               SourceField -
>Then
               CurrentDate(Date Function)----->Else
Hope this will help !!
Regards.
Jeet.

How to test ABAP mapping used in a Integration Process node

Hi,
anyone can suggest me how to debug an ABAP mapping used into a transformation node belonging to an Integration Process ?
Thanks.
Francesco

Hi, Francesco.
I've debugged ABAP Mapping with SXI_MAPPING_TEST transaction.
If you have creted a scenario including your ABAP Mapping, you only hace to put the correct sender/sender interface and receiver/receiver interface. You have to put some XML document as an input.
I wrote in my code the Break-point instruction an debugged the process without problems.

How to use variables in logical file name definition FILE

Hi Friends,
How can I use variables in logical file name definition (tcode FILE). The requirement is to pass value in these variables (based on selection criteria), and use it as part of file name. You quick response will be highly appreciated.
Thanks,
Kuldeep Joshi

Hi,
Thanks for your reply.
In detail, the scenario is like I have created an Open Hub. Its working fine. Now I am planning to execute this open hub using process chain and for that I have to define the file output on application server along with logical file name (using tcode FILE). The logical file name contains two variables (defined in FILE) i.e. z_dept and z_fiscperiod.
Filter value in DTP ( I will read these values from Ztable using routine )
Dept = R&D
Fisc period = 004/2009
Variables defined in tcode FILE:
z_dept for Dept
z_fiscperiod for Fiscal Period
Logical file name : <z_dept>_<z_fiscperiod>.csv
Now the challenge is to populate filter values in these two variables so that the filter value can be used for naming the output file.
My last option is to read/update SAP standard table used for storing variable values (i.e. PARAMVALUE)
Please let me know if you can help me in this issue OR is there any standard method/FM to populate value in these variables
Thanks,
Kuldeep

Using "Route" activity in process flow

Hi, I have a situation where I want to run one of two maps, depending on how many rows are in a particular table, i.e. something like:
If table X rowcount > 100000
then run map A
else run map B
What's the most straight forward way to set this up in a process flow? I assume I need to write a PL/SQL function that returns the # of rows in the table...but after that I'm a bit stuck, and the OWB user guide has next to nothing on how to use the ROUTE operator.
Thanks in advance!
Scott

Hi David, thanks a million, that helps out a ton. I thought we had to use variables, with SET / ASSIGN and the ROUTE operator to do this...all of which are Enterprise ETL functionality.
It seems like the method you outline below, in addition being easier, actually is legal even if we don't have Enterprise ETL. Is that correct?
Thanks!
Scott
Includes the following advanced process flow functionality:
- Activity templates
- Variables support: assigning and passing variables and using the Assign and Set Status activities
- Looping activities such as For Loop and While Loop
- Route and Notification activities

Substitute variables for external process activity in process flows

Has anyone used with success substitute variables such as ${Working.Rootpath} for external process activity?
I can't get it working. Variables aren't substituted and my scripts fail.
Sample value for parameter_list parameter for external process I use is:
|${Working.Rootpath}|
and in the script I get:
${Working.Rootpath}
which is of course not what I expected.

In documentation is Working.Rootpath so there is a bug in documentation. It is ugly because it's hard to guess.
Thank's for your reply Michael. I checked all that you described. Previously I had Working location set to "Use default location". When I changed it to actual location substitute variables started to work properly.
If I correctly understand "Use default location" means: use location associated with process module. And for execution it works but for substitute variables doesn't. So I think it is a bug.
Next thing is variables in the script itself. From examples sent by Mark (script: cd ${Working.RootPath}...) they should be set in environment and accessible to shell. This doesn't work for me but it is not described in documentation and can be easily achieved by passing parameters. So that's not a problem.
One more question: Should I open tars and file bugs describing what we found?
