Global variable in Mapping

Hi,
Is there a way to declare a global variable in a mapping? e.g if I want to use a counter variable...
Zahid

Hi again,
I've previously used the mapping input parameters successfully to bind a name (read-only) to the value of an expression, which is particularly effective when you want to filter an ODBC source with a non-trivial expression, which otherwise means the filtering is done on the target side (expensive).
Unfortunately, Zahid wants to change the global variable within a transformation, and that is a side effect I believe is not allowed in SQL (set mode). Also, transformations live in a separate PL/SQL package, which means that the transformations have no access to the mapping input parameters. Hence my (untested) suggestion that using row mode and developing a separate "global variable" package might do the trick.

XI 3.0: Using global variables in mapping

Hi everybody
Since it seems that during mapping you have only access to messages fields, does anybody has got idea or a workaround to use global/external variables or constants during mapping??
Example: i would like to store the mail address where i send my error mails outside each mapping program (something like using a properties file or something like that).
Any idea???

Hi,

Also some of the RUN TIME CONSTANTS are available in your BPM. So if you are trying to retrieve those variables in your Mapping(that is used in BPM), also read the following thread.

PI Global Variables

I have been looking for ways to support global variables (across maps, not within a single map) and cannot find anything.
My scenario is a synchronous RFC out of R3, through PI, and out to a vendor's product lookup service...all synchronous. The issue is that I need to log values from the RFC request as well as values from the vendor response.
I can get the process working with a sync/async bridge in a BPM (the async part being to write out vendor response to the log file). What I need is some way to store RFC request values and map them into my log file too.
Unless there is some Global variable method that spans across an entire process, I figure I need to do something special in the BPM. Can I achieve this by creating a split/copy of my request message, sending one out to the vendor and holding the other in a BPM wait of some sort. Then when the response comes back, split/copy it also and let one copy respond to SAP and the other merge up with the waiting request? Or something like this?
Thanks for any suggestions.
Keith

Hi Keith,
I think you can achieve your requirement using a combination of Lookup & BPM (Sync Async bridge) techniques. May be you can try the following;
Integration process design:
START
^^
ReceiveStep(Open SyncAsyncBridge)
^^
Transformation (MultiMapping with lookup)
^^
SendStep(Send RFC Resp &Close SyncAsyncBridge)
^^
SendStep(Send Log message)
^^
STOP
Details:
Step1: Use Receive step to receive the sync RFC message and ope n S/A bridge.
Step2: In Mapping (Transformation step) use Mapping lookups (RFC/DB/SOAP) to get the Vendor response and in same mapping generate both the Log message and RFC response as output messages (Multi-Mapping)
Step3:Send RFC Response message and close S/A bridge
Step4:Send Log message
Hope this helps.

Global Counter Variable - Graphical Mapping

Hi there.
Can anybody help with implementing a global counter variable in the graphical mapping please.
I am trying to populate the "SEGMENT" field of an IDoc with the correct sequence, i.e. add 1 for each new segment. The IDoc has several segments, most of which are embedded. I have tried using the "counter" function but this seems to reset back to one for each instance of it being called.
I would appreciate any pointers.
Thank you.
Mick.

Hi see this for implementation
defining Global Variables
ArrayList arrVI;
int counter =0;
Initialization Section
arrVI= new ArrayList();
assignment
arrVI.add(sVI[iLoopCounter]);
counter++;

fetch Values
for (int i =0;i<counter;i++)
result.addValue(arrVI.get(i)+"");

Mapping global variables

Hi,
I have written a UDF which returns data in the form of a string with comma ',' seperated.
I wanted to get each value seperately and directly map them to the output data type.
Is it possible to seperate the string that is comma seperated and pass them into Global variables and use global variables to directly map with reciever datatype?
Or is there any other method to handle this using other existing functions to split the returned value?
Please help. Thanks in Advance
Rohan.

Use of global variables like g_cnt_transactions_transferred in the LSMW

Hi SapAll.
when i had a look at the some of the LSMW's whic use IDOC as the object of uploading data into SAP from external Files i have found in the coding under the step "Maintain Field Mapping and Conversion Rules" that they use some of the global variables like below
.if p_trfcpt = yes or sy-saprl >= '46A'.
EDI_DC40-DOCNUM = g_cnt_transactions_transferred + 1.
endif.
.EDI_DC40-CIMTYP = g_cimtyp.
.EDI_DC40-MESTYP = g_mestyp.
.EDI_DC40-MESCOD = g_mescod.
.if p_filept = yes.
EDI_DC40-SNDPOR = g_fileport.
elseif p_trfcpt = yes.
EDI_DC40-SNDPOR = g_trfcport.
endif.
my doubt is where i can find these variables 'g_cnt_transactions_transferred ','g_cimtyp','g_mescod','g_fileport','g_trfcport' in the LSMW and what is the use of the variable 'g_cnt_transactions_transferred ' in the LSMW.
I have treid to find out the above listed variables looking in step 'Maintain Field Mapping and Conversion Rules' under global variabels list and the other lists also but i couldnt found.
can any one help me in this ?
regards.
Seetha.

Hi Seetha,
In the LSMW Workbench go to the option user menu. And check the option display conversion program.
Now when you execute with the radio button on dislplay conversion program, you ll see the code that got generated in the background while you built your LSMW.
The global variables that you have mentioned are bound to be there in this program generated in the background..
You can put a break point here and see for yourself what the value of these global variables are at runtime.
File port, TRFC port , no. of transactions executed by one run of the LMSW Idoc program , message type are some of the fields that you have asked for .

Dynamic CSV file name in target (Multiple workflow calling same dataflow with new global variable value)

Hi their,
I have multiple data flows doing 90% of the process same. The difference is in source query where clause and target flat file.
I used the global variables to dynamically change the query where clause easily, but I need help in dynamically changing the target flat file (CSV file).
What I want to do is have multiple workflows, which will first set the global variable to new value in the script box and then call the same data flow.
Please let me know if you have any solution or any idea which might put me in the direction to my quest for solution.
thank you,

Hi Raj - in your content conversion for lineitem .. read the additional attribute as well.
Change your source strcture and additional field company_code
As you are already sending the filename for each line item using the UDF.. it's just you need to modify your UDF to take another input i.e. Company Code.
or
If your PI version is > 7.1 use the graphical variable to hold the filename..
and while sending the company code information for every item just use the concat function to append filename & company code..

Global variable in XSLT

Hi,
I have a requirement in XSLT mapping where i sum up all the data related to amount field and then want to display total that i have added in the another node
eg.
<Detail>
<xsl:variable name="etotal" select="sum(ns0:pay/ns0:checkList/ns0:check/ns0:deductionList/ns0:adjustment/ns0:amount/ns0:amount)"/>
</Detail>
<Trailer>
<TotalDeductionAmount><xsl:value-of select="$etotal"/>
</TotalDeductionAmount>
</Trailer>
how to do ?
since the above example the scope of the variable is local and cannot be accessed globally. how to declare a global variable and then assign value to the variable
or is there any other method to do this in XSLT
Thanks in advance

Hi,
Please see below sample code is solving your problem. Global variable can not solve the problem, you need to use templates and call then appropriately.

Reg Global Variable in PI 7.1

Dear All
We have a scenario where we need to validate contents of variuos fields in an xml file. As the validations are complex we want to store the exceptions inside a global variable so that all the exceptions can be segregated at a single point.
Consider the following source structure
Vendor No.
Order No.
Invoice No.
Claim No.
Customer No.
CustomerName
Needs to be maaped to following target structure
Vendor No.
Order No.
ClientName
Exception
Text
if in the Sender side, Vendor no/orderno/invoice no is not there then the text fied should be populated in the Reciever side with the exception , this challenge has to to be achived using the Global Variable.
Regrads,
Sourabh

Hi Nirmal,
The exception you are going to send is a Type of Text message or its like java exceptions??
If you are validating 5 or 6 fields then its better to do it at Message mapping level,use Global variale ,first create a global variable and check the condition if Vendor not exists pass exception message to Global Variable.
Then map this global variable to Text message segment in Receiver side.
I had done validating Two CIDX Orderchange documents using JAVA Mapping,its worked perfectly for my requirement(bit complex requirement).

Raj

Global Variable as an array

Hi All,
Culd you please tell me where I can declare a global variable as an array in PI 7.1.
In PI 7.O we used to store global variables in java sections and it was recognized across mapping in message mapping
In PI 7.1 I have declared a variable in init function in functions tab in message mapping but its not recognized in my mapping.
Could you please help me with this?
Where I have to declare a global variable so that I can use it anywhere in mapping?
Thanks in advance

Global Variable in entity beans

Dear Friends,
For example let us think that we have an entity bean for Customer.
and we created an instance of that bean for customer A and then for customer B.
So will the global variables in Customer bean be shared across Customer A and Customer B or will there be seperate instances for both Customers.
Thanking You,
Chamal.

Your concepts seem to be a little messed up.
For entity bean, remember the following:
1. each object/instance of entity bean represents a record in a database
2. when a client looks up an entity bean (typcially by using findByPrimaryKey method on home object), the record from database is searched and its values are stored in Entity Beans variables (this is probably what you mean by Global Variable. But thats an incorrect terminology in Java/J2EE. Class attribute is the correct word)
3. In step 2, you fetched a record and that record is represented by a java object, which is nothing but entity bean.
4. Now if you make changes to this java object, these changes will persist in the database. That is the essence of entity bean.
5. If you use the home object's findByPrimaryKey method and look for the same record, no new object will be created. The 2 remote objects will point to the same entity bean on the server.
6. If yo use the home object's findByPrimaryKey method and look for another record/customer, a new object will be created on the server. This new entity bean will map to the new record.
Note taht the attribtues of CustomerA and customerB will never be shared.
hope that helps

Reading a global variable from tomcat with JNDI. Example not working

Hi you can help me to make this example work?
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup("java:comp/env");
Object o = envCtx.lookup("testvariable");
<GlobalNamingResources>
<Environment name="testvariable" type="java.lang.Boolean" value="false"/>
Nice greetings Christian

I found out that in addition to having the JNDI lookup code, you have to
- have the environment variable declared in the app server configuration
- have a resource-env-ref entry in your webapp module
- have the application container bind your named variable with the global variable
I am using tomcat 5.5, and have done the following. with success.
the following example uses the default sample environment variable in the tomcat server.xml
in tomcat server.xml:
<GlobalNamingResources>
<Environment
name="simpleValue"
type="java.lang.Integer"
value="30"/>
</GlobalNamingResources>
in my application's web.xml:
<resource-env-ref>
<description>Test read resource environment variable</description>
<resource-env-ref-name>simpleValue</resource-env-ref-name>
<resource-env-ref-type>java.lang.Integer</resource-env-ref-type>
</resource-env-ref>
in my META-INF/context.xml (or otherwise, in tomcat's context deployment configuration)
<ResourceLink name="simpleValue" global="simpleValue"
type="java.lang.Integer"/>
Note: in theory, the named resource by your web app could be different from the global environment variable, but here they are the same 'simpleValue'
This is the really important step, that with out it, nothing works.,
the context.xml is known to work with tomcat when it exists in META-INF/context.xml inside the .war file (i use war files to deploy, but you should be able to create META-INF/context in an unpacked webapp directory too, and tomcat will find it.,
I can not say what it is like for other app servers, but this mapping step is the critical point that i discovered after A LOT of hair pulling.
then, make use of it, i created a jndiTest.jsp:
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.naming.InitialContext" %>
<%@ page import="javax.naming.NamingException" %>
<%
try {
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:/comp/env");
Object o = ctx.lookup("simpleValue");
%>
<%=o%> 
<%
catch (NamingException ex) {
System.err.println(ex);
%>
since my server.xml defines the value for 'simpleValue' to be 30, this page displays 30

Using Global Variables in Data Quality Address Cleanse Transforms

I am currently developing in Data Services 12.2.
I am trying to dynamically populate the List Owner information in the option tabs of the USA Regulatory Address Cleanse by using global variables. It populates the 3553 with the variable name instead of the value assigned.
According to the Technical Manual, it is possible to use global variables in Data Quality Address Cleanse transforms:
However, you can use substitution parameters in all places where global variables are supported, for example:
Query transform WHERE clauses
Mappings
SQL transform SQL statement identifiers
Flat-file options
User-defined transforms
Address cleanse transform options
Matching thresholds
Does anyone know if it is possible to use global variables in the option tab of the Address Cleanse; if so, can you describe how it is done?
Thanks in advance,
Rick
