Hi Munna,
Try Creating a UDF in your mapping name it like: "Create"
Paste the below mentioned code in it
========================
String str = a;
if(str != null && str.length()>0)
return "true";
else
return "false";
========================
2) Save this function .
3) Now Map like this
(Source Node->UDF Create)->Check if it returns a string "true"--> if yes Map it with source node->add this in the "then" of an "if with out else"---->Target node.
4) Test now in testing tool in Message mapping.
Try it.
it will work

Pl: reward points if it worked

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.

How to remove browser warning message in HTML 5 Cap 8 projects?

How to remove browser warning message in HTML 5 Cap 8 projects?

My conclusion after a morning struggling with this, is that there's no point in suppressing the message if your html5 content then goes on to misbehave in Firefox (like mine does). I've chosen to keep the popup, but change the wording to refer Firefox users to a completely separate Flash version. The wording of the popup is also in CPM.js.
Before you all shout at me, no I can't use the multiscreen.html approach, because my Flash version will have to be non-rescaleable, because web objects don't rescale in Flash.

Missing node in Message Mapping when test mapping??

Experts,
I have the following Mapping Structures:
Sender:
<Recordset> 1-1
   <Records> 1:unbounded
        <field1>1:1
        <field2>1:1
Receiver:
<Recordset> 1-1
    <Header> 1-1
     <Records> 0-unbounded
           <field1>
           < field2>
     <Trailer> 1-1
Mapping is completed for all fields here.But one thing I notice is on Receiver side : all nodes are Green exept Records - it is Gray with some red smal dot in the gray..
1.Question: What this means?Shouldn't all nodes turn green after mapping is done??
2.When click on TEST on Message MApping I dont even see the Receiver Records node appearing on right(receiver side) But I was able to see Header and Trailer...Why the Records is missing??
On the other hand the result from the test is successfull which is even more confusing ,How come it can be succesful since Records is not there...
I can provide screenshots if needed for more clarity ..Any help is appreciated asap..Thanks much to all!
J...

Hi John,
   It is very simple and there is no complexity with this problem.
<b> 1.Question: What this means?Shouldn't all nodes turn green after mapping is done??</b>
        If you mapped the source field to the correspoding target field..all the target fields get turn to green color. If you didn't mapp any target field that filed should appear with gray color..comming to the small circle in the recordset field...it is indicates that ..that field is "Unbounded".
   For resolving the above issue...do the mapping like this.
   <Recordset>---><Recordset>
   <Records>-------><Records>
   <field1>----><field1>
   <field2>-----> <field2>1
Keep the empty constant value for the target field Header...
   empty constatnt---->Header.
So once you done this check the mappping it will execute fine and even you able to see the recods node in the target structure.
Please let me know if you have any queries...!
Thanks and Regards,
Chandu.

How to remove red pin om map app

how do i remove red pin on map app,im talking about red pin not the blue pin?

The label that is with the pin. Touch the blue arrow to the side of it and then touch where it says Remove Pin.
EDIT: I just re-read what you said. If it is a red pin, it is from a searched address. In that one, you have to cancel the search and the pin will go away.

How do I resolve error message "mapi was unable to load aplzod.dll"? Outlook2010 on Win7

Attempts to open Outlook calendar files (apparently located) on iCloud result in the error message "MAPI was unable to load the information service C:\PROGRA~2\COMMON~1\Apple\Internet Services\APLZOD.dll". Be sure the service is correctly installed and configured."
I am running Outlook 2010 on Windows 7. I have uninstalled and reinstalled iTunes with no apparent effect. Is this a problem with iTunes or Outlook, how do I resolve it?

That's part of my problem - I was getting the error message when I tried to click on iCloud in the Calendar portion of Outlook 2010. I don't know where it was generated (iCloud, iTunes, or as an add-in to Outlook).
After my original post I tried restoring my computer to a date when I knew this worked, the restoration worked, and I can access my calendar. So that problem resolved itself.
I do have another question, but I'll post it separately. Thanks for your response.

How to implement validations in message mapping?

Hi experts,
I have a simple requirement:
I have a simple synchronous scenario:
SOAP -> XI -> RFC
In a message mapping, one of the fields in the source message is of type String.
However, the target application (RFC) does not expect a non-numeric characters in this string.
My question is how can I perform the validation in XI and tell the sender that this field contains Non-numeric characters?
Please help.
Thanks.

Hi Jai
I already have alerts configured.
But what I had in mind is to send a response to the sender (The sender is waiting for a reply since this is synchronous), instead of telling the sender through an alternative means such as email, sms, etc.
Is this possible?

How to pass GUID in message mapping

Hi ALL
I would like to populate one of the target fields with SAP PI GUID or Message ID.
Can you please let me know, how to get the GUID in my message mapping and map it to the target field.
Thank you,
Ritu

Hi Ritu ,
its simple you can pick the messageID from the streamtransformation constant and map it to ur target field .
use this UDF it does not taes any input and its output can be mapped to target field where you want to populate the messageid.
java.util.Map param = container.getTransformationParameters();
String MSGID = (String) param.get (StreamTransformationConstants.MESSAGE_ID);
return MSGID

How to remove browser warning message in HTML 5 Cap 6 projects?

Hello,
Is there any way to remove the following pop-up message from published HTML 5 Captivate 6 projects?
Adobe Captivate
This browser does not support some of the content in the file you are trying to view. Use one of the following browsers:
Internet Explorer 9 or later
Safari 5.1 or later
Google Chrome 17 or later
Our Blackboard 9.1 tech analysts recommend that all students use Firefox, and I'd rather that they don't have to read the above warning message every time they open a module. (The module did work as expected, even in Firefox.)
Thank you,
JAB

Changing .ini is the advice eventually given in the Phonegap forum. (Browser compatibility error in Captivate conversions).
But there's a much simpler solution offered at the bottom of this page - just a few lines of code at the end of
function initializeCP() { in the index.html file header.
A More Mobile-Friendly Captivate HTML Template | Float Mobile Learning
Even better, that blog post also shows how to remove the play button for autoplay and make touch response times faster (for mobiles) - refer to blog for how.
var _onComplete = cp.complete;
cp.complete = function() {
    _onComplete();
    $("#CPUnSupportedBrowserWarning_ID").remove(); // Removes browser warning
    setTimeout(function() {
        cp.movie.play(); // Skips the play button
    }, 1);

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 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"
http://help.sap.com/saphelp_nwpi71/helpdata/en/27/db283fd0ca8443e10000000a114084/content.htm
Regards,
Prateek

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

Remove segment in Message Mapping

Hello,
I am sending the ORDRSP.ORDERS05 to an external message ORDERS05 which is based on the
same structure as the ORDERS05.
However I should not be sending all E1EDP01 segments. If the item belongs to a higher level item, then it should not be sent. If the item belongs to a higher level item then the field E1EDP01-UEPOS exists and has a value. In that case I should not transfer the E1EDP01 segment.
See example for what I mean. This would be the source message:
- <E1EDP01 SEGMENT="1">
<POSEX>000010</POSEX>
<ACTION>000</ACTION>
<MENGE>1.000</MENGE>
<MENEE>PCE</MENEE>
<PMENE>PCE</PMENE>
- <E1EDP01 SEGMENT="1">
<POSEX>000020</POSEX>
<ACTION>000</ACTION>
<MENGE>1.000</MENGE>
<MENEE>PCE</MENEE>
<PMENE>PCE</PMENE>
<UEPOS>000010</UEPOS>
- <E1EDP01 SEGMENT="1">
<POSEX>000030</POSEX>
<ACTION>000</ACTION>
<MENGE>1.000</MENGE>
<MENEE>PCE</MENEE>
<PMENE>PCE</PMENE>
<UEPOS>000010</UEPOS>
This first item is the header item and does not contain the field UEPOS.
The next two items belongs to item 000010 and should not be sent.
In this case only the POSEX 000010 should be sent.
The target message should then look like this:
<E1EDP01 SEGMENT="1">
<POSEX>000010</POSEX>
<ACTION>000</ACTION>
<MENGE>1.000</MENGE>
<MENEE>PCE</MENEE>
<PMENE>PCE</PMENE>
I think this should be possible with the standard functions in Message Mapping, and I have been playing around with CREATEIF and EXISTS, but have had no success. Anybody has any idea what to do?
Regards,
Per Rune

Hi Per,
If I understood correctly ,Do like this and let us know.
UEPOS---> Exists ----------->
and------>Not-------> IfWithoutElse --> E1EDP01----->E1EDP01
UEPOS-> Equals -> POSEX
Thanks!
