N:1 Multi mapping issue at PI 7.1

Hi Experts,
I have 2 different source message types (824 & 997) to be mapped to target mail package (N:1 mapping).
I have added both the source messages (provided xsd for 824 & 997 as External defination) under Tab "Signature" .
Now when I go back to the Tab "Defination" it loads 2 messages but of similar message Type (either 824 or 997).
e.g
Messages
--Msg1
    -- 824
--Msg2
   -- 824   OR
Messages
--Msg1
    -- 997
--Msg2
   -- 997   INSTEAD OF
Messages
--Msg1
    -- 824
--Msg2
   -- 997
Please help , what could be the problem?
Thanks,
Jyoti Acharya

Hi Jyoti ,
this problem will come in case of IDOC also if you have two IDOC fo same Basic type but different message type .
basically Basic type is responsible for the IDOC structure message type just signifies what message is being populated in that structure .
so in case of idoc If your basic type is same and message type is different then you can use one source XSD in both the message mapping and then you can use two Interface mapping , there in source you can give the correct IDOC name and in message mapping section you can copy the MM manually .
then in interface determination we can use conditional ID to select the required Interface mapping .
However your scenario looks to be different but I shared this information as I have faced similar issue while using IDOC of same basic type but different messagetype.

Multi Mapping issue - *Split mapping created no messages*

Hi,
The scenario I am trying to test is a multi mapping scenario where I am trying to split one source message and create two target messages by using two different inbound service interfaces, one for each message type.
I am on PI 7.1 and when I test message mapping and operation mapping using the payload from SXMB_MONI, it is successful. Whereas when I test the scenario end to end I am getting the following error messages:
Runtime error
*Split mapping created no messages*
Start tag ns0:MessagesStart tag ns0:Message1Close tag ns0:Message1Start tag ns0:Message2Close tag ns0:Message2Close tag ns0:Messages
Could someone please help
Cheers,
S

Hi,
(1)First change the occurrence of target message to 0..unbounded.
(2) Do the mapping and test it under test tab of mapping whether your mapping is working fine creating target records.
(3) Copy the source code from mapping and remove the unwanted tags "as Mark said " those were created due to multimapping.
Then test that file and that will work.
You can follow this link .

Multi mapping issue

Hi ,
I am using a multi mapping(with out bpm) in my scenario. One source structure is mapped to 3 different targets and these 3 different targets are using 3 different adapters.
There will be a indicator from the source structure which descriminates all the 3 targets.
How can I restrict the XI to send only to one target based on indicator in the source structure?
EX: If the indicator in the source structure is 1000 then I want to send this message to only one target specified in the mapping.
So my problem arises where in, because we are using multimapping 1:n, if I trigger a message in the proxy it will be sending to all the 3 targets. I don't want this.
Appreciate your help on this.
Thanks
bpr

HI
You need to have 3 different channels for 3 receivers with receiver agreement for all three.
Go to Receiver determination and under configured receivers you can specify condition you want.
If the indicator in the source structure is 1000 then I want to send this message to only one target specified in the mapping.
select the left operand as indicator field from source type
= as Op
right side is 1000
Against this configure the receiver you want to send data.
Thanks

Duplicate Message ID issue in case of Multi mapping (without BPM)

Hi Experts,
I am doing one sample Example for my requirement of converting the single source message data into the multiple Target messages.
for example, when sender system is sending the 5 sale order details into a single message in PI then my Inbound proxy class of ECC R/3 receiver system must get this sale orders separately, that means inbound proxy class method must be triggered separately for 5 sale orders from sender system. for achieving this, I have used the Multi mapping concept in ESR (without BPM).
This scenario is in Asynchronous mode.
The below screen shots give the details on what I have configures so far.
IN ESR
IN ID
IN SXMB_MONI of PI
IN SXMB_MONI of ECC R/3 Receiver system (Error in Processing)
due to this error, inbound Proxy class method is not being triggered for the single Sale order details as well,
please let me know how to tackle this duplicate message ID issue when we have multiple payloads to process in a single message.
please also let me know if is there any other workaround to fulfil this requirement.
Thank you,
Regards,
Jagesh

Hi Nunu,
Check the below blog for restrictions.
Multi-Mapping without BPM - Yes, it’s possible!
Restrictions
Messages that result from the split in a mapping-based message split are sent using one AE. So only adapters running on the AE are supported. In particular, this means that target IDOC message splits are not supported since the IDOC adapter is not part of the AE.

Issue with java mapping in a multi-mapping scenario

Hi
    We have a 1:n multiple mapping scenario in XI and the source is R3 proxy and target side is files. So, creating multiple file from a single message from R3 .
R3 --> XI --> Multiple files
Structure of the output of the multi-mapping is
- <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
- <ns0:Message1>
<Transaction>
</Transaction>
<Transaction>
</Transaction></ns0:Message1>
</ns0:Messages>
wherein each Transaction node represents a file.
Now, we need to introduce a constant /string like
<!DOCTYPE Transaction PUBLIC \"-//XXXXXX//DTD BatchReceiptAuthorization//EN\" \"http://dtd.XXXXXXX.com/dtds/ReceiptAuthorization.dtd\">
on each of the files at the very beginning - i.e within each transaction node , in the above structure, we need the above DTD string to be written. To do this, we added a java mapping as the second mapping after the message mapping that creates this string. Is this the right approach and would it produce what we are expecting ?

Hi XI Gurus
                   In my scenario, I sent the inputstream that is being passed to the Java execute method - to trace and I see that the whole of the xml file - as shown below - which is the output of message mapping ( from the first mapping step ) in sent to the execute method of the java mapping a single call
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<Transaction> </Transaction>
<Transaction> </Transaction>
</ns0:Message1>
<ns0:Messages>
So, I modified Java mapping program to look for multiple occurences of <Transaction> tag and prefix them with my constant DTD Literal - which is the primary reason , why I had to use Java mappings after the message mapping.
Now, I get an error is XI- SXMB_MONI
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

Should I create multiple outputs - as many as the numberof target split files ( of type outputstream ) from the execute method in the java program ?

Multi-Mapping runtime issue

Hi, Friend:
We are using BPM to collect two type of message (Msg1 and Msg2) and map to target message (Msg3),
                          ------Receive1-------
Start --Fork(start)                            Fork(stop) ---Transformation--Send
                          ------Receive2-------
When we created all the messages from scratch, the process works, the process worked.
After we use external definition (xsd), it always fails on transformation step.
However,if we put the payload to test in message mapping, it success.
Any thoughts ?
Thanks
Liang

Hi, Praba:
We have tested in both multi-mapping, and also interface mapping by using the same payload the causes error in runtime, they are all fine.
The error happens on tranformation step: some nodes have very simple mapping like one to one, it can not create target node (see attached part of trace).
Once we change the complained node mapping from a constant value, the next test shows next target node can not be produced.
If the node is attribute, only required attribute complains, if the node is element, the node with min occurence of 1 complains

Multi mapping problem

Hi All,
I tried a simple BPM with a transformation step involved. I have done a multi mapping here. One source msg to 2 target msgs.When I test the mapping using test tab with the incoming payload from SXMB_MONI, I am getting 2 msgs as expected. But during runtime, this is not happening.
These are the output msgs I am getting. It does not have any node in it. The second msg doesnot even have a closing tag for namespace.
<?xml version="1.0" encoding="utf-8" ?>
<ns:MT_TGT xmlns:ns="urn:bpm:file:2rec">
<Header />
</ns:MT_TGT>
<?xml version="1.0" encoding="utf-8" ?>
<ns:MT_RECR xmlns:ns="urn:bpm:file:2rec" />
Any pointers on this issue.
Thanks & Regards,
Jai Shankar.

Hi Bhavesh,
Yes. I checked the source msg in BPM container element. I tested the mapping with thet payload. It is working fine. I can see the source payload in container element as expected. But the MESSAGES_OUT has 2 msgs in the format I pasted above.
Thanks & Regards,
Jai Shankar.

SAP PI 7.3 AEX Multi mapping: Mapping failed with exception

Hi
I am encountering an issue with the multi mapping in SAP PI 7.3 AEX system.
Requirement for my interface is to pull a single file which has multiple records from the file directory.
Interface need to split the single file to multiple files.
For this I have implemented multi mapping in SAP PI 7.3(Stand alone Java) to split the single file to multiple files just like the way it is done in SAP PI 7.1. Tried this interface in SAP PI 7.1 system and works fine end to end.
I have done the testing in mapping(Test tab) in operational mapping, I could see response is getting generated successfully.
But when testing end to end,
I could see message is getting failed during mapping with the exception "failed to execute: ArrayIndexOutOfBoundsException: 1” .
Note:
Occurrence has been changed to 0..unbounded in the Signature tab of the message mapping & same interface works fine in SAP PI 7.1
Our system is currently on SAP PI 7.31 (AEX) SP05 Patch "0".
Kindly let me know if someone has any idea on this particular exception in SAP PI 7.31 multi mapping Interface.
Thanks & Regards
Ram

Hi Jegathees,
Thanks for your reply.
In PI 7.31:
As we are doing 1:n mapping, I have maintained the source side occurrence as "1" and target side occurrence as "0..unbounded" in the signature tab of message mapping.
Even in PI 7.11 Occurrences were maintained in the same way.
Can you please give me more details of how exactly multimapping in PI 7.31 is different with respect to PI 7.1
Thanks & Regards
Ram

Multi-Mapping Error in PI 7.1 - External Definitions

Hi all,
We have just upgraded to PI 7.1 from 7.0 and run into an issue with message multi-mappings, just wondered if anyone else had met the same issue and worked it out...
When creating a message mapping, we are using as the target an external definition which is defined by an XSD generated by a third party tool (Seeburger).
When I map 1:1 (1 source message to one target message) in the message mapper, all is fine but if I try to create a multi mapping, I get an error. The process is:
a) I have a message mapping with one target message, defined as an External Definition.
b) I then go to Signature tab and add a second target message as an External Definition
c) Click back to Definition tab
d) Get the error "Object XXXXX | YYYYY not found" - where XXXXX is the external def name and YYYYY is the namespace (the SWCV namespace that is, not the XML namespace)
This only seems to happen with External Definitions which are autogenerated and I strongly suspect that is has to do with the fact that the tool that generates them always does so without an XML namespace. I have not proved this though (other Ext Defs with namespaces work for multi-mappings but that is not the only difference so I can't be sure that is the issue but have a strong hunch. This problem did not occur in 7.0.
Anyone got any ideas?
Thanks,
Chris

Hi,
This would not be of much help but, I was able to encounter this issue in XI 3.0.
What we did was to manually edit the XSD and add a namespace to it. I'm not sure if PI 7.1 is able to handle mutiple namespaces, so we limited it to this value <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> and made sure that this value is used for all the External Definitions used in the multi-mapping.
Regards,

How to achieve Java Multi-mapping in PI 7.31?

Hi,
I have a simple file to file scenario. Want to do 1:n transformation using java mapping.
Followed this link Multi-Mapping using Java Mapping - Process Integration - SCN Wiki . But the result was a single message with three root segments. where as the requirement is to get three messages each having one root segment. Please suggest how can we achieve this.
PS: Please suggest a solution specifically using java mapping.
Thanks

Hi Nisar,
I had the same issue when I was trying to achieve this. I am able to create the target structure with multiple subsegments but unable to get them in individual multiple messages.

Multi Mapping

Hi all,
I need a help on how to go about the following scenerio.
XI first performs a multi-mapping that creates two output messages:
One is the target message in Flat File Format. The mapping also generates the filename for the output message which should follow the format 11_<Unique ID>.txt. This filename is written into the XML Payload of the message. The File Adapter later does a flat file conversion on the message. In this step, the filename is not written into the flat file. Instead, it is used by the file adapter as the target filename.
The file should be placed in a specified directory.
The mapping also creates a second message, which only contains the same filename in the payload. This message goes to a second File Adapter, which also does a flat file conversion. Its output only contains the filename that was created by the mapping, followed by a line break. The output of this File Adapter is written into the same directory as the first file. The name of the output file is 11.catlg. If the file already exists in the target directory, the output needs to be appended to this file.
Thankyou.

Shruthi,
It seems the payload contains the filename and this filename as to be used in the Communication Channel of file adapter.If my understanding is correct the problem can be solved by the Variable substitution. Refer the below link:[http://****************/Tutorials/XI/Variable/substitution.htm]

XSLT mapping issue in parent child relation

Hi Guys,
i have one XSLT mapping issue. Mapping scenario is from IDoc to file.
IDoc structure is as below
<ZLOIPRO1>
<E1AFKOL>
     <A></A>
     <B></B>
     <E1RESBL>
         <MATNR>1</MATNR>
         <CHARG>1</CHARG>
         <ZSBL>
             <MTART>ABC</MTART>
         </ZSB>
     </E1RESBL>
     <E1RESBL>
         <MATNR>2</MATNR>
         <CHARG>2</CHARG>
         <ZSBL>
             <MTART>ZHA1</MTART>
         </ZSB>
     </E1RESBL>
     <E1RESBL>
         <MATNR>3</MATNR>
         <CHARG>3</CHARG>
         <ZSBL>
             <MTART>ZHA1</MTART>
         </ZSB>
     </E1RESBL>
</E1AFKOL>
</ZLOIPRO1>
As you can see 'E1RESBL' is repeatative. Now my issue is i need to select 'MATNR' and 'CHARG' from 'E1RESBL' segment when first occurance of 'ZSBL/MTART' with value 'ZHA1' appears. i.e. my output would be MATNR = 2 and CHARG = 2.
I hope i am clear. Please let me know if any solution for this.

Hi,
Try this
<xsl:if test="./ZSBL/MTART == 'ZHA1'">
<xsl:for-each select="./E1RESBL">
<MATNR>
   <xsl:value-of select="./MATNR"/>
</MATNR>
<BATCH>
   <xsl:value-of select="./CHARG"/>
</BATCH>
</xsl:for-each>
</xsl:if>
You might need to do some changes in the above.
Thanks,
Prakash

Multi Mapping error

Hi,
I am required to have a IP recieve 3 IDOC types triggered from BD10 . It can trigger 3 or more IDOCs. For Eg.
1 ARTMAS (only 1) , 2 INFRECs and 1 LIKOND.
If anyone IDOC has come then after a waiting period of 1 minute it should come out of FORK.
My IP is like this.
In a FORK there are 4 branches.
1) ARTMAS receiver
2) Loop(infinite) with INFREC Receiver and a Container Operation to collect all IDOCs
3) Loop(infinite) with LIKOND Receiver and a Container Operation to collect all IDOCs
4) A wait Step with a container operation to initialize endtime variable
necesary branches: 4
The Fork Comes out when the end condition is met ie the End variable is Set or if all the IDOCS have come.
Corelation on MATNR.
Next I have the transormation and send step.
In the MM i have 3 Source and 1 Target.
Artmas 0-1 occurance
INFREC 0 - unbounded
LINKND 0-unbounded
I have created the Target with External Definition and have set the correct occurance in the XSD file
I have mapped the neceessary Segments from INFREC and LIKOND and all the Segments of ARTMAS to the Target structure.
In SXMBMONI it says error on Outbound side and
I see Mapping Exception when I seen in WORKFLOW.
Is my design Correct?
I have tested the Interface & Message Mapping they are correct
Request your help.

2. Inside interface mapping, when u say read interface, is it diplaying both the interface.
Also check ur input

EA4500 – Smart Wi-Fi interface and Windows Network Map issues

I purchased this Router about 2 weeks ago as a phased upgrade of our Home Network, primarily to enhance media streaming. It has the latest firmware preinstalled from the factory. Prior to the purchase and installation of the EA4500 Router I replaced my old Motorola SurfBoard SB6120 DOCSIS 3.0 Cable Modem with a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem. My old Linksys E2000 Router worked perfectly with the SB6141, with the exception that the E2000 wasn’t IPv6 enabled, but does have 10/100/1000Base-T Ethernet (RJ-45) and Internet ports.
The EA4500 has been installed for about 10 days and seems to have improved local network speeds and I don’t seem to be having any Internet connectivity issues. However, there are some disturbing issues with the EA4500 and the AE3000 I purchased. There are 11 devices connected through the Router; a Dell Desktop (wireless with the AE3000), a Dell Desktop (Ethernet), a Dell Laptop (wireless), 2 Canon Printers (1 Ethernet and 1 Wireless), 2 Western Digital 1TB MyBookLive Network Drives (both Ethernet), a WD TV Live Streaming Media Player (wireless), an Apple TV media player (wireless), an iPad (wireless), and an Android Smartphone (wireless).
Issue 1 – The Linksys Smart Wi-Fi interface appears to be unreliable at times!!! I’ve read about this problem here on the Community involving the EA6500, so I don’t know if this is a Linksys Server issue, as suggested in a few responses, or a bug in the Router firmware, or defective hardware. However, when the interface locks up, it can’t be accessed from a wireless or wired connection. Usually, powering down the Router and then powering it back up and restart will allow it to function again. However, at times before the interface completely locks up it shows either just a white screen or the security screen will show no firewall features enabled. This is a little scary, so I’ll do a complete reset and setup; this is becoming a pain in the rear!!!!! Is there any hope for this being fixed, in this Router, not the next generation??????????
Issue 2 - All of my network devices show up in the Router’s Device List. Except for the Apple devices they also show up, when they are online, in Windows 7 Explorer under Network and when you click on Network they are correctly displayed as Computers, Media Devices, Network Infrastructure, or Storage. However, when you click on “Open Network and Sharing Center” and then click on “See Full Map”; it fails with the response “Windows cannot create the network map. Responses from other devices on the network are delayed or there is an incompatible router on the network”; no device map is shown. When I follow the link for more information, the only thing that stands out is “A device on the network, such as a hub or switch, is not working properly or is not compatible with the Link Layer Topology Discovery (LLTD) protocol, which Windows uses to create the map. To fix this problem, disable the device, turn it off, or remove it from your network”. All of my network devices showed up on the Network Map with the old E2000. This issue is the same on all of my computers, either wired or wireless. Any known solutions for this, or is it as Windows suggests; an incompatible Router????
Thanks in advance for any insight or solutions. With the issues I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.

thebluemamba_24; Thank you for your suggestion; I finally found time yesterday to perform an extensive evaluation before I return the Router. However, rather than trying to add devices manually, my rationale was if the EA4500 can’t process them correctly, automatically, it needs to be returned anyway, so I added devices normally letting the device an Router handle the process.
In thinking through this issue, all devices on our network are detected and identified by Windows Explorer on Windows 7 computers; except of course the Apple and Android devices (Apple TV, iPad, and Smartphone). So, I wondered if one of those three devices being added to the Router’s device list was somehow causing issues or interfering with Windows 7’s ability to generate a Network Map. Therefore, my approach was to turn off or disable all devices on our network, reset the Router to factory defaults, reestablish the Router to my custom Home Network configuration using a Windows 7 PC that has LAN and Wireless access to the Router, then add one device at a time and check with each addition to see if Windows 7 could still generate a Network Map.
With the Router reset and reestablishment complete; I began the process of adding one device at a time and checking to see if a Network Map was being generated. What I discovered was when a recent addition to the network, a Western Digital WD TV Live Streaming Media Player, was connected (wirelessly), Windows 7 could no longer generate the Network Map and the failure was consistent. The only way to get the Network Map to work again was to remove power from the WD TV Live, although it remained in the EA4500’s Device List; simply turning it off didn’t help. Since I’d originally witnessed the Windows 7 Network Map working with the Linksys E2000 Router that the EA4500 replaced, I decided to test the WD TV Live with that Router. It worked initially, but it failed consistently after the first success. Interestingly, the failure indication was a little different, but nevertheless generation of the Network Map failed.
I’ve tried changing a few settings on the EA4500 as well as the WD TV Live, but nothing helped. There was a recent firmware update to the WD TV Live, so I might try rolling back the firmware to see if it makes a difference.
The Network Map issue might very well be an issue with the WD TV Live, not the Router, but after reading many threads on this Community I have reservations that the problems I’m experiencing with the Smart interface lockup will be fixed. I suspect new emerging replacement products will be the focus and these older products will be abandoned and no more firmware fixes will be forthcoming and I don’t want to spend more money for a new product just to fix old problems and get something that works properly. The Network Map issue is troublesome, but the lockup of the Router’s “Linksys Smart Wi-Fi” interface is a serious matter to me. It appears that once it locks up, the only way to correct it is a power off restart; not practical if you’re traveling and trying to access settings remotely; the selling point for this feature.
Given the problems I’m experiencing with the EA4500 and AE3000, I guess I’ll return them. Too bad, because otherwise the EA4500 seems like it’s a good Router. I’ve been brand loyal since the Linksys WRT54G came out, but after reading this Community and with my personal experience with the EA4500 and AE3000, now I’ll probably give the NETGEAR N900 equivalents a try.
