How to export parameters from Message Mapping

You can make use of this export parameter only in transformation step of Integration Process. You may use the following "Parameterized Mapping Programs"

If you have defined the signature of your UDF then the return value of the UDF must be assigned to the Export paramter of message mapping.
Basically import parametrs represents the inputs to be passed for that function(message mapping here)
and export represents the output of that function.
so in your case if you want toassign the value to Export parameter (ERROR_TEXT) in UDF catch block
assign the error returned to the ERROR_TEXT field

Hope this is clear

How to set EXPORT parameter from message mapping

Again, ask the question of export parameter.
I wrote a java version transformation and it worked good with export parameter.
However I can not work it out in graphical message mapping. I refered http://help.sap.com/saphelp_nwpi71/helpdata/en/43/c3e1fa6c31599ee10000000a1553f6/frameset.htm.
In PI7.1, I add an export parameter "EXPORT_PARA" in the "Signature" tab. Are there any special step to assign this parameter to an UDF? I did not find a way to do it.
And then I define an UDF,
public String SetExportPara(String sss, Container container) throws StreamTransformationException{
String str = "GOOD";
GlobalContainer gc = container.getGlobalContainer();
OutputParameters paras= gc.getOutputParameters();
if(paras.exists("EXPORT_PARA ") == true) {
paras.setString("EXPORT_PARA ", str);
}else {
str = "NOT FOUND EXPORT_PARA";
return str;
And I assign this UDF to one element of my output XML, I tried to run it in IE, it always output "NOT FOUND EXPORT_PARA.
why?????
I know there is a blog : https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/8654. [original link is broken] [original link is broken] [original link is broken]
But it did not talk how to set export parameters.

Hi,
i read thread
How to export parameters from Message Mapping
and blog
/people/jin.shin/blog/2008/02/14/sap-pi-71-mapping-enhancements-series-parameterized-message-mappings
but not found issue
in this topic
http://help.sap.com/saphelp_nwpi71/helpdata/en/43/c3e1fa6c31599ee10000000a1553f6/frameset.htm.
if i writting this code in UDF, i getting an error.
If use this code:
GlobalContainer gc = container.getGlobalContainer();
OutputParameters paras= gc.getOutputParameters();
paras.setString("EXPORT_PARA ", str);
the export parameter is defined locally (in transformation step area). In integration process area parameter is equal to NULL.
How send export parameter to Integration Process? For exapmple, i wanna send parameter to other transformation step in my integration process.
thx.

Use exported parameter from message mapping (via UDF) in next mapping prog

Is there any chance to assign an exported parameter from one message mapping to another mapping program within an operation mapping?

Hi,
Try using dynamic configuration
1. Set value in message mapping and
2. Get value in java mapping
Refer this link http://help.sap.com/saphelp_nw04/helpdata/en/43/03612cdecc6e76e10000000a422035/content.htm

Error exporting XIM file from message mapping

Hi.
We are trying to export XIM files from message mapping with CTRL + SHIFT + 0 but is not working. Iu2019ve tried to solve it with this link:
[http://support.microsoft.com/kb/967893]
but is still not working.
We are with SAP PI 7.11 SP 07. Is there any SP level prerequisite to be able to export message mappings in xim files?
Thanks a lot.

I think you can't use 1.4 in SAP PI 7.1.
I've downlaned the JDK 5 and I've associated it to enviroment variables PATH and JAVA_PATH but the application is still opening with JAVA 6.....
Any idea?
Regards.

Export parameter in Message mapping UDF

Hi, I use PI7.1.
I defined an Export parameter in Message mapping "Signature" tab.
And as http://help.sap.com/saphelp_nwpi71/helpdata/en/43/c3e1fa6c31599ee10000000a1553f6/frameset.htm,
I wrote in my UDF as follows:
public String myudf(int var1) {
String str="test";
if(exists("MY_PARA") == true) {
getOutputParameters.setString("MY_PARA", str);
return str;
However when I ran the test, it said there is "syntax error".
I guess the reason is not found the method exitst() or getOutputParameters. Anybody can help? thanks

Data lookup in R/3 database from message mapping

Hi,
I am trying to lookup R/3 database from Message mapping.
Instead of creating Java class outside XI and then importing into Integration Repository, I have defined an advanced function in message mapping and trying to connect to R/3 using JCo API. But System is giving syntax errors as listed below:
Check Result for Object CustomerDetailsMap Source code has syntax error:

Can somebody help in rectifying the problem?
Thanks and Regards,

Hi,
can u post the java code which u have used in mapping.
There is a doc in XI-Articles. "How to Perform SAP Data Lookups Within XI Mappings" By Jerome Delune 16 October, 2003. Try looking at this article and do ur mapping.
Hope this helps you.

How to export photos from photo gallery to my iPad

How to export photos from photo gallery to my iPad

I had no trouble finding the "Export" tools in the "File" menu. They are greyed out when no photo is selected, but they are functional after selecting one or more photos.
I agree that it would be nice to have the "Reveal in Finder" option back, but they probably don't want us mucking about inside the Photos library structure.

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.

Mark
