Query on Graphical mapping

Hi All,
I have a requirement to do a graphical mapping from a Single row in Source to Multiple rows in target.
Source:
<SingleRow>
quanutity_1
quanutity_2
quanutity_3
</SingleRow>
Target:
<SingleRow>
 <item>
 quantity
 </item>
 <item>
 quantity
 </item>
 <item>
 quantity
 </item>
</SingleRow>
please suggest.
regards,
Piyush

Usage of useOneAsMany:
The first input parameter expects the list of values that we want to propagate to the target message.
The second input parameter expects the number of iterations or how many times we want to replicate the value given in the first parameter.
The third input parameter is the list of context changes. Depending on this parameter the source values will be propagated to the target after every context change.
Also,For this function to work as expected, the first two parameters must contain the same number of contexts while the last two parameters must contain the same number of values
Thanks

Is it possible to replace XSLT mapping in place of Graphical mapping

Is it possible to do XSLT mapping in place of Graphical mapping, in any normal scenario?
Means the fuctionality we do by using Graphical mapping(like the operations by using node functions etc...) could possible to do with XSLT Mapping?

HI
yes it is possible to replace the graphical mapping with the XSLT mapping.
But using XSLTs degrade the performance of the interface and moreover they are not easily maintainable.

Handling PI 7.1 RFC Lookup Exception in Graphical Mapping

Dear Experts,
I would like to know the better way of handling PI 7.1 - RFC Lookup Exception in Graphical Mapping without using BPM. Say I perform a RFC Lookup from PI 7.1 Graphical Mapping and it fails due to RFC server down. In this case I suppose the RFC exception would be returned as response to the mapping? But, am really not sure how this response (RFC Exception) could be effectively used. Please clarify.
Thanks,
Hussain.
Edited by: HussainShaik on Oct 26, 2009 8:24 AM

Hi Hussain,
I am not sure if I understood you query completely.
IF the RFC look up raised some exception then how this is going to impact your interface will depend your mapping (which you did in ESR)
(the following is adopted from help.sap,com)
If you handled exceptions by selecting Use Exceptions checkbox in the function properties of the standard function, the mapping editor adds an additional parameter in red (the bottommost return parameter) to the standard function in the data-flow editor. If you do not assign a target field to this return parameter, ignore the RFC exceptions (the message mapping is not terminated at runtime). Otherwise the mapping runtime transfers the exception as an XML structure and it can then be evaluated in a user-defined function, for example. If there is no exception, the mapping runtime transfers an empty context.
If you have not selected the Use Exceptions checkbox, the mapping runtime terminates the message mapping if an exception occurs during the RFC lookup.
Is this you are looking here?

Conditional mapping in Graphical mapping

Hi All,
I have a conditional mapping requirement i.e.I have 2 nodes ( collections/collection/object and extensions/collection/@name) in the source structres. Both nodes are identical and have unbound occurences. Based on certain condtions I need to map second node in the source node to target node ( Items ). Below is the condition.
If first node '/MT_FCI_CONTRACT_EXPORT/fcidataexport/objects/object/collections/collection/object/@classname' (Occurs Unbounded ) value is not 'contracts.LineItem' and second node '/MT_FCI_CONTRACT_EXPORT/fcidataexport/objects/object/extensions/collection/@name' ( Occurs Unbounded ) value is 'MATGRP_COLLN' then only map source field '/MT_FCI_CONTRACT_EXPORT/fcidataexport/objects/object/extensions/collection/row' ( occurs unbounded ) to target node 'Items' ( Occurs unbounded ).
I have done this mapping using If condtions and did some context changes. My second condition is working fine but my first condition is not working as expected. Its only taking value in the first occurences and based on that passing first condition. But I need to check in all occurences whether value 'contracts.LineItem' is not exist then only I need to pass that condition. Please let me know how to achieve this.
Please help me to achieve my requirement.Thanks.
Regards,
Rajesh

Hi Rajesh,
To reply your query first we have to understand the exact requirement . So I am writing my understanding below and solution for it .Kindly reply if your requirement is different.
you have three source field which is involved in mapping .@classname, @name, and row and target side you have node item .
Now you have to check for all classname and name that if classname is not equal to contracts.LineItem and @name is equal to MATGRP_COLLN ( both the values I have considered as constant) then map row to target node item. i.e if classname and lineitem is occuring 4 time and two time both are satisfying both the codition then generate two target Item node .
Solution.
classname -> (CollapseContext)->equals to ContractLineitem --not -->
AND -
IIF WITHOUT ELSE
Name -
>(CollapseContext)-->equals to MATGRP_COLLN--
>
the condition of if without else function will be output of AND and in then map row----.(collpasecontext) finally the output of if without else will be mapped to item
note :all ittalic is Graphical mapping functions .

Bug in exists() function of XI Graphical Mapping Tool?

Hi!
If I connect a source field with the exists() function in XI Graphical Mapping Tool and the tag exists it returns TRUE, otherwise it returns FALSE, so everything works as expected.
But I have to connect a user-defined function with exists(). The user-defined function will either calculate a value or set Resultset.SUPPRESS.
If there is a value the exits() function returns TRUE, however if Resultset.SUPPRESS is set it does also return TRUE! This looks to me like a bug in exists() function. Shouldn't it always return FALSE if the input is Resultset.SUPPRESS?
Regards, Tanja

Hi Stefan!
> The exists() function checks, if a queue is empty.
> An empty queue is not represented by the
> SUPPRESS value.
> If inside a queue there is a SUPPRESS value, the
> queue is not empty.
Ok, so it's not a bug and the exists() function is working as expected.
> If you want the exist() function after a UDF, provide
> an empty queue, or easier: return the values "true"
> or "false" directly from the UDF.
Yes, that's how I actually solved the problem. The UDF was used at several places where the ResultList.SUPPRESS output was needed. So I copied the UDF and changed it so that the output was TRUE or FALSE instead.

Graphical Mapping Vs XSLT mapping Vs Java Mapping Vs ABAP Mapping

Hi Experts,
I have a question regarding different message mapping options available in XI namely
Graphical Mapping
XSLT mapping
Java Mapping
ABAP Mapping
Q1: Which amoung the above mappings is the best and why?
Q2: On what cases Graphical, XSLT, Java and ABAP Mapping should be used?
Q3: Is it true that graphical and XSLT mappings are converted into Java class internally?
Kindly help!

Hi,
There is no hard and fast rule for using the mapping techniques.
Graphical Mapping is used for simple mapping cases. When, the logic for your mapping is simple and straight forward and it does not involve mult hiearchical mapping requirement. and context handling.
Java and XSLT mapping are used when graphical mapping cannot help you.
When the choice is between Java And XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. XSLT can lead to a bad perfrormance if the Source XML is huge.
Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.
SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.

How to use Advance java function in graphical mapping in XI 2.0?

Hi,
currently I am using a simple java function to make an RFC call to R3 system.
I want to avoid making connection for each lookup. Instead I want to make a single connection for whole message queue and get the corresponding values in some array or container object.
please suggest a solution.
I think this is possible using Advance java function, but I am not able to find any example on using Advance java function at help.sap.com.
thaks in advance.

Hi!!!
I'm not sure if I understood you well.
Do you want to preload some data into your structures in the memory and keep them there so you don't need to make a new connection during processing the whole message or every message?
In my opinion you can cache some data during processing a message, but it's impossible to cache some data between processing messages.
If you write your java mapping or you use graphical mapping (even with user-defined function), then you have a java class. The problem is that XI 2.0 reloads this class during processing every message, so even if you load some data from your data source into your structures in the memory, this data will be lost after reloading your mapping class.

How to debug global values in UDF in a graphical mapping

Hi Every one,
I got a situation in PI where i have to use global values in graphical mapping UDF.
I can't able to get the values in "Display Queue " option.
Can you please tell me what is the best way of debugging global variable in graphical mapping UDF.
1. I declare one array list in the global values
2. store some values using another UDF to the arraylist.
3. I am traversing the values in the arraylist, but the values are not showing in "Display Queue".
What is the solution to this.

Did you try with trace.addInfo?

Should we avoid Graphical mapping and stick with Java mapping?

After developing mappings in XI for a month, I just don't see any good reasons to use Graphical mappings over Java mappings. Maybe some experienced users here can give me some valid reasons why we should choose Graphical mappings. Here is what I think:
Disadvantages of Graphical mappings:
1. No way to perform automated unit testings. This is probably the biggest reason I hate it. You can do some tests manually when you work in Integration Builder. But there is no way you can write some unit testing utilities to automate the task.
2. Complexity. Even for some simple requirements, your Graphical mappings can become complicated and hard to understand. A lot of times, I find myself staring at several dozens of graphical nodes and try to understand what it does.
3. Impossible to reuse. This is totally against the DRY (Don't repeat yourself) principle. For example, to generate messages for JDBC adapter, it is common to have two identical fields for primary keys: one in the access node and another in the key node. If you change the mapping logic in one, you have to remember to change the other.
Advantage with Java mappings:
1. Fully automated unit testing. You can create JUnit tests along with your Java mapping classes and use Maven or other build tools to perform automated unit testing.
2. Your choice of XML parsing and binding. With Java mapping, you can choose any open source framework for XML parsing and binding. For example, with XMLBeans, I can convert XML input message to a Java object, transform to another Java object and write to output message. And each Java object is generated from its corresponding XML schema.
3. Highly reusable. We can use fundamental object-oriented designs to create highly reusable mapping components.
4. Better version control. Since the mappings are just Java classes, we can use CVS or SVN to track code changes.
5. Better build tools. We can fully utilize build tools like Ant and Maven to automate the build, unit tests, or even generate documents and mapping web sites.
So do you guys agree? Maybe I am still new to XI or I am missing some important things. But at this point, I just don't see why I should use Graphical mappings. Is there anyone developing XI interfaces completely with Java mappings?
Thanks in advance for any comments!

Could you explain more why the graphical mapping has better performance? I thought the graphical mapping is compiled into a Java class in the runtime anyway.

> right (if you haven't mentioned it as constants)
I mainly think about inheritance. If I have to build 10 interfaces and they all have some common behavior, I can create a base interface class to encapsulate the common logic. But with graphical mapping, you have to duplicate them in each interface.
> Disadvantages of Java mapping:
> 1. Performance
Same as above. I just don't see why Java has worse performance. I actually think Java should have better performance. You can optimize the code anyway you want. In some cases, you have to use queue functions in graphical mapping but it's not necessary in Java.
> 2. All might not be well versed with Java Code(though

I am not asking everyone to abandon graphical mapping. I am just wondering which one is better when you have skills for both.

You can create functions in Java too. All you have to do is to remember the function name.

Graphical mapping issue with useOneAsMany if segment does not exist

Hi all
I have an issue with graphical mapping in an IDoc to file scenario. I need to have header level fields mapped to line item fields. Whether or not and how many source header segments of the same type exist depends on a qualifier (QUALF). This is generally working if I use the following graphical mapping:
if QUALF = 001 then <source> -> removeContext -> useOneAsMany -> splitByValue -> <target>
... with setting QUALF, <source>, and the second input for the useOneAsMany to the highest possible context node.
Nevertheless, if the segment with the qualifier 001 does not exist in the source then the mapping throws the error "Too few values in first queue in fuction useOneAsMany". Whatever I've tried, the mapping wants to execute the useOneAsMany statement anyway and I haven't found a way to omit this. Whether the target would be created with an empty value or not created at all would be secondary. Would eventually somebody have a solution to this problem?
Thanks in advance,
Daniel

Daniel,
try using mapWithDefault function before useAsmany
if QUALF = 001 then <source> -> removeContext -> MapwithDefault->useOneAsMany -> splitByValue -> <target>
I think it takes care even if the value occur in the contaxt or.

Graphic Mapping:IDOC to File-Avoid Error in Adapter Engine

Hi all,
I'm using Graphic Mapping in my IDOC to File scenario in which each segment in source IDOC will generate a ROW in target File with the condition: DATBI >= currentdate (and some other conditions)
I have a UDF and use the mapping function CREATEIF for this purpose:
DATBI -> UDF -> CREATEIF -> ROW
Problem scenario: In the source IDOC if all the segments have DATBI < currentdate then there is no ROW created, and I get the error in Adapter Engine
Exception in XML Parser (format problem?):'java.lang.Exception: Message processing failed in XML parser: 'Conversion configuration error: Unknown structure ...
How can I avoid this?
I've tried to put this condition using XPATH in Interface Determination and got the error.
There is a way to use function current-date() in XPATH condition?
Thanks for your help,

Hi all,
How can I "suppress the row node if condition fails"? I'm new in PI, so please give more details.
My FCC as follows:
Record Structure: Record, Row
Row.addHeaderLine 0
Row.fieldSeparator ,
Record.fieldSeparator 'nl'
Row.endSeparator ; 'nl'
It works fine if the condition satisfied.
In Message Mapping, I've use Test to double check my mapping, and in the scenario that conditions fails, there is no Row in the target message.
Please advise.
Thanks,
Elaine

Non-XML payload in graphical mapping

Experts,
I have a scenario where I need to trigger a graphical map which eventually populates an IDoc (custom) structure but the Idoc is not being populated with any of the source field.
My source data is a flat file.
1. I dont want the src file content to be transformed to XML.
2. But need to trigger the map (graphical map) to populate the constant values in IDoc.
However, even with a src message type with a single String type element (no sub-element), the mapping is failing giving XML parsing error.
Question is:
1. If it is possible to call a Graphical map without the XML conversion of the source? if yes.. how?
2. Otherwise can I use Java / ABAP mapping? because since the input parameter for IF_MAPPING~EXECUTE - source is XSTRING type. So can I pass a flat file instead?
- Shibaji

HI Shibaji
1. I dont want the src file content to be transformed to XML.
2. But need to trigger the map (graphical map) to populate the constant values in IDoc.
XI expects some XML if it is empty also it will work but you need to send dummy XML for triggering the mapping. You can pass just a blank field as source to trigger this.
. If it is possible to call a Graphical map without the XML conversion of the source? if yes.. how?
IE expects XML to process so you need to send some data to execute mapping. I don't think you can avoid XML conversion.
Otherwise can I use Java / ABAP mapping? because since the input parameter for IF_MAPPING~EXECUTE - source is XSTRING type. So can I pass a flat file instead?
Java or ABAP mapping also require some source and target to be formed and when you can meet the requirement for triggering the mapping from Graphical. It will complicate using Java/ABAP mapping
I think if you have a source dummy message with single field with 0..1 occurrence then it should trigger your mapping without any error
Thanks

Create Attachment within Graphical Mapping using UDF

Hi!
We want to create an attachment witihn a graphical mapping using an UDF function.
I use that function:
public String addAttachment(String filename, String mimeType, String content, Container container) throws StreamTransformationException{
 BASE64Decoder decoder=new BASE64Decoder();
 try {
 GlobalContainer globalContainer = container.getGlobalContainer();
 OutputAttachments outputAttachments = globalContainer.getOutputAttachments();
 Attachment attachments = outputAttachments.create(filename, mimeType,decoder.decodeBuffer(content));
 outputAttachments.setAttachment(attachments);
 return "Adde1: "+filename;
 } catch (Exception e) {
 return e.toString();
(SDN helped me much in creating that
This function has no compiling errors, anything workes fine:
It takes 3 input-parameters, see also: http://help.sap.com/javadocs/pi/SP3/xpi/com/sap/aii/mapping/api/OutputAttachments.html
filename (ok, more or less contentID)
mimeType (more or less contentType)
content: Base64-encoded String which should be set as content
In my sample I use the following constants for that function:
filename = "fn1.txt"
mimeType="application/xml"
content = "UG9seWZvbiB6d2l0c2NoZXJuZCBhw59lbiBNw6R4Y2hlbnMgVsO2Z2VsIFLDvGJlbiwgSm9naHVydCB1bmQgUXVhcms=" --> cames directly from http://de.wikipedia.org/wiki/Base64
When using the message, I got this error within SXMB_MONI:
<SAP:AdditionalText>com.sap.engine.interfaces.messaging.api.exception.MessagingException: Could not queue receive for
message 0022642d-b106-02df-8e8c-f41c243bd112(INBOUND). Reason: java.lang.NullPointerException: while trying to
invoke the method com.sap.aii.af.sdk.xi.lang.Binary.getBytes() of an object returned from
com.sap.aii.af.sdk.xi.mo.xmb.XMBPayload.getContent()</SAP:AdditionalText>
This looks pretty much the same as Add Attachment from ABAP Mapping but this tread is also not answered.
Adding attachment from PI level looks also in that direction, again, no answer.
So, I was wondering if someone has solved such problem?

Hi Divyesh!
We did it that way:
1. Choosing the XML-Mailstructure as Destination as described in Configuring the Receiver Mail Adapter - Advanced Adapter Engine - SAP Library - Example (XI payload with mail package)
2. now we have created a UDF for creating the "content"
public void getContent(String[] text, String[] attFname, String[] attType, String[] attContent, ResultList result, Container container) throws StreamTransformationException{
// vergleich ob alle att-Arrays selbe anzahl haben
if (attFname.length!=attType.length || attFname.length!=attContent.length) {
 result.addValue(Integer.parseInt("Fehler: alle Attachment-Eingänge müssen die selbe Anzahl an Elementen haben!"));
 String CRLF = "\r\n";
 String output="This is a multi-part message in MIME format."+CRLF+CRLF+
 "--"+getBoundary(container)+CRLF+
 "Content-Type: text/plain; charset=UTF-8"+CRLF+
 "Content-Disposition: inline" + CRLF + CRLF +
 text[0]+CRLF;
for (int i=0;i<attFname.length;i++) {
 output+="--"+getBoundary(container)+CRLF+
 "Content-Type: "+attType[i]+"; name="+((char)34)+attFname[i]+((char)34)+CRLF+
 "Content-Disposition: attachment; filename="+((char)34)+attFname[i]+((char)34)+CRLF+
 "Content-Transfer-Encoding: Base64"+CRLF+CRLF+attContent[i]+CRLF;
output+="--"+getBoundary(container)+CRLF;
result.addValue(output);
This UDF is configured as "QUEUE"
We have configured this input-structure
The Content itself is allready base64.
So we can call this mapping and it creates a Multipart-Mail for us.

Graphical mapping is Java Mapping??

Someone told me that ABAP mapping is faster than Java mapping cause it runs on ABAP stack straight away, where as Java mapping runs on Java stack and then transfers the result to ABAP stack whic reduces effieciency. Does that mean me should prefer ABAP mapping over Graphical mapping as that is also java mapping in the background??
Regards,
Ashish

according to SAP, the graphical mapping (which generates java code) is the fastest mapping and hence the first choice. Personally I prefer XSLT even though it is said to be the slowest because of the way XSLT runs the mapping. However, I never experienced any problems but found it much easier to handle than the graphical mapping especially when the mapping gets a bit tricky and you have to work with many queues.
I doubt that the Abap is necessarily faster because it depends how you write your source code, whereas the graphical mapping is already optimized

ABAP mapping Vs Graphical mapping

Hi
I have an inbound scenario to R/3 where the purchase requisition has 300 line items. I was wondering if it is easier to do ABAP mapping for such scenarios instead of Graphical mapping as it would be better performace as ABAP mapping is executed on ABAP engine?
I would appreciate valuable inputs.
Thanks,
Arjun.

Hi Arjun
As mentioned above in the comparison Blog between 2 mappings, i dont think it gives clear picture, if you have some specific work which getting Dynamic Configuration stuff for example, then you will have to Look for ABAP mapping Class, my thinking is that it depends completely on the requirment.
For ABAP mapping you can go to
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/e3ead790-0201-0010-64bb-9e4d67a466b4
