ABAP mapping split messages and dynamic filename

Hello,
i have set up a IDOC to file scenario where the IDOC is split into several files, which works fine. In addition to this it is required to set a dynamic filename out of the ABAP mapping for each file. If only one file is created this works already as well but how do you set the dynamic configuration when the messages are split?

Andreas

you cannot do dynamic configuration for message splits. The below is from SAP help.
Adapter-Specific Attributes and Multi-Mappings
In multi-mappings, there are multiple message headers with adapter-specific attributes. The mapping API can only access one message header. This has the following consequences depending on whether there are multiple source or target messages:
u25CF     1:n Transformation
If there are multiple target messages, the header for the adapter-specific attributes is copied for each message. This means that you can only create one header for all adapter-specific attributes, and not individual headers.
u25CF     n:1 Transformation
This variant is only possible for multi-mappings in integration processes. If there is more than one source message, read-access to the adapter-specific attributes of the various message headers is not possible at runtime.
u25CF     m:n Transformation
All afore-mentioned restrictions apply here. Developers can at most write the same adapter-specific attributes for all target messages to the header, without read-access to the attributes of the source messages. m:n transformations are only supported within integration processes.
What i will suggest is to use BPM to have the message split i.e 1:N mapping and then after that have another mapping 1-1 to have the dynamic configuration

Multi-Message-split with ABAP mapping and adapter specific attributes

Hi all,
With ABAP-Mapping I split 1 message to n messages.
So many files are generated in file-Adapter.
Everything fine.
But now I want the file names different using adapter specific attributes.
It is not possible to use variable substitution and write the file name in payload because of receiver restrictions.
I tried this with following similar coding in ABAP-Mapping:
data: lt_records TYPE MPP_DYNAMIC_TAB.
 Loop.
 l_file_name = "payload-Inbound"-information
 ls_record-namespace = 'http://sap.com/xi/XI/System/File'.
 ls_record-name = 'FileName'.
 ls_record-value = l_file_name. "l_file_name comes from inbound-payload
 append ls_record to lt_records.
 Endloop.
CALL METHOD dynamic_configuration->set_all_records
 EXPORTING
 records = lt_records.
If I start the interface I see in the monitoring the dynamic configuration with many entries for file-name in the the SOAP-Header mapping of the request message (following extract):
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:DynamicConfiguration xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPAADDRESS.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPABROKERROLE.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPACOMPANYSEGMENT.XML</SAP:Record>
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">BPACUSTOMERROLE.XML</SAP:Record>
The result is that all files have the same file name (last entry in dynamic configuration).
Is it possible to write the adapter specific configuration in ABAP-mapping for every single result message??
Thank you for your help,
Florian

Hi Florian,
I've a different idea...I dont think its a "right solution" but just another work around..it involves a BPM...
In your ABAP mapping..set the dynamic config with as many variables as number of different messages...i.e. use the variables like 'FileName1', 'FileName2'...'FileName6' instead of 'FileName'. But use the same namespace 'http://sap.com/xi/XI/System/File'
Call the above mapping in a BPM and capture the individual messages and set the attribute 'FileName' from the values of 'FileName1' to 'FileName6' accordingly using Message Mapping and then send the message using the 'Send' step.
before you try this, try using the variable names 'FileName1' ...'FileName6' in the receiver adapters...enable the ASMS. I know we need to select which variables from the dynamic config to be used by the adapter by specifically selecting 'FileName', 'Directory' etc...but just give it a try and see if it works..
Or..instead of using a BPM..you can combine Henrique's idea...use Adapter module to set the value for 'FileName' from variables 'FileName1'...'FileName6' accordingly.
hope I'm clear..lemme know if you have any questions..
cheers

Dynamic configuration in integration process using abap mapping

Hi everybody,
i have the following scenario:
file adapter -> integration process -> file adapter
The integration process uses an ABAP mapping and sets the filename in dynamic configuration as follows:
*-- Set Parameter
 clear ls_dyn_record.
 ls_dyn_record-name = gc_dyn_config_name.
 ls_dyn_record-namespace = gc_dyn_config_ns.
 ls_dyn_record-value = <new_file_name>
*-- Write configuration
 ir_dyn_config->add_record( ls_dyn_record ).
But now the new filename is not reflected in the file adapter (receiver). In the integration monitor (SXMB_MONI) i still find the old filename.
Whats wrong?
Elko

The ABAP mapping is more complex, setting filename in Dyn. Conf. is just one step in mapping.
If I check the Workflow protocol of the Integration Process, I find the following in the Trace of the ABAP-Mapping:
The filename has been set to 3233340.SWNF00HW.P10I. The Suffix P10I has been added in the ABAP mapping.
When I check the subsequent message in SXMB_MONI I find:
The added suffix is missing in the filename !!

ABAP Mapping Questions

Hi,
I am trying to get my head around ABAP mappings and have a few questions.
In the below code sample which I find in every example and blog it talks about specific steps -
*initialize iXML, * create iXML factory object, * create streamfactory object, * create input stream object, * initialize the input xml document, * parse the input xml document
In these steps the code is always exactly the same so my question is are these just standard steps that are implemented every single time an abap mapping is used and hence only standard lines that never have to be changed or will they be different depending on the mapping.
I am trying to work out where I will begin my coding.
So would somebody be so kind as to give me a brief explanation of the above mentioned steps.
Thank you
METHOD if_mapping~execute.
* initialize iXML
TYPE-POOLS: ixml.
CLASS cl_ixml DEFINITION LOAD.
* create iXML factory object
DATA: ixmlfactory TYPE REF TO if_ixml.
ixmlfactory = cl_ixml=>create( ).
* create streamfactory object
DATA: streamfactory TYPE REF TO
if_ixml_stream_factory.
streamfactory = ixmlfactory->create_stream_factory( ).
* create input stream object
DATA: istream TYPE REF TO if_ixml_istream.
istream = streamfactory->create_istream_xstring( source ).
* initialize the input xml document
DATA: idocument TYPE REF TO if_ixml_document.
idocument = ixmlfactory->create_document( ).
* parse the input xml document
DATA: iparser TYPE REF TO if_ixml_parser.
iparser = ixmlfactory->create_parser(
stream_factory = streamfactory
istream = istream
document = idocument ).
iparser->parse( ).

Hi,
The above lines you mentioned deal with initialization of the iXML parser for parsing through the XML payload, so they would remain the same for all mapping where you are parsing the input payload.
The coding for you specific mapping will begin after this, something like :
* Implements the DOM generating interface to the parser
iparser->parse( ).
emp_node_collection = idocument->get_elements_by_tag_name_ns( name = 'Order' ).
emp_node_length = emp_node_collection->get_length( ).
emp_node_iterator = emp_node_collection->create_iterator( ).
where you start reading the xml node values.
Hope this helps.
Regards

Splitting, Staging and Sending

HI,
I am trying to create a solution where I am looking to Split one xml into three xmls using Multimapping. The three xmls are like the staging tables. These three xmls then will be transformed into three output xmls and send to three different locations in File Directory.
Scenario:
                                      -----> Staging xml    -------> Output Message (xml)
Third party sysytem (xml) ---> SAP PI -----> Staging xml    -------> Output Message (xml)
                                       -----> Staging xml    -------> Output Message (xml)
I am looking for a solution without BPM.

Messaging and remoting through coherence

Hi all
I'm really coherence noob...
But I want to implement subj by coherence...
How to implement reliable delivery to queue and/or topic (just done what jms can do) ?
(now I'm listen a map with messages, and remove received messages from the map.. damn... it's to messy)
How to allow client call service in any available node once? (i do it by the same way but with blocking queue in client)
I think it would be great to describe such common "EA patterns" implementations in coherence wiki... isn't it?

Hi,
first of all, Coherence might not be the best option to do messaging and remoting, as it is not the purpose of Coherence to solve these problems.
However, the listener for a map with messages is not a bad start. Backing map listeners are also something you might want to look at.
Compared to the cache listener they give you a balancing of the load across storage enabled nodes at the price of the backing map listener being able to listen only for events for keys it owns.
You could also look at InvocationService. That is most similar to remoting and messaging, however InvocationService is not fire&forget, if the invoked node goes down, nothing guarantees the execution of the invocable instance, so you would have to implement failover (retry, redelivery and duplication detection).
Best regards,
Robert

Acces dynamic configuration variable (e.g. filename) in ABAP mapping class

Hi experts
I am searching for a possibility to acces a dynamic configuration variable (DCV) in an ABAP mapping class. Since I could not find a solution in SDN and other sources, I hope somebody in this forum can help me.
What I already found is the following code which can be used to set a DCV, but what I would be interested in is how to read a DCV.
Any help is appreciated.

Message split ABAP mapping

Hello everybody,
for a special mappging I use ABAP mapping -everything fine.
But I need to split the message with ABAP mapping.
Does anybody know if this is possible ?
In the ABAP-class I use the interface IF_MAPPING. This has as a result parameter the parameter RESULT Type XSTRING (no table).
It only works to add to XMLs in 1 XML string, but my result have to be 2 XML files.
Alternatively would it be an idea to use multi message mapping (graphical first) AND then ABAP-mapping for special mappings?
Thanks a lot,
Florian

Florian,
for multimappings in coded mappings (xslt, java and abap mappings) you'll also create a single stream, but in this case, the stream may have the following format:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
 <enter your first message here>
</ns0:Message1>
<ns0:Message2>
 <enter your second message here>
</ns0:Message2>
</ns0:Messages>
where <ns0:MessageX> tags refer to each different target message type.
In the case you have a 1:n split, you'll have only 1 message type, but may have several messages within it.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
 <My_message id=1>
 </My_message>
 <My_message id=2>
 </My_message>
</ns0:Message1>
</ns0:Messages>
Also, remember that, when you define an interface mapping as multimapping (meaning, you set either source, target or both interfaces to multiple messages, your input stream will also contain the <ns0:Messages> and <ns0:MessageX> tags, so you need to treat them in your mapping program.

Henrique.

Message Splitting in ABAP Mapping

Hi Everybody,
I have Implemented ABAP mapping in my Scenario and have used message splitting. That is for each header node of source corresponding number of target nodes should be created.I have a source node under which i have 5 subnodes and when this source node repeats again i need to generate two target nodes with 5 subnodes in each of the target header node.
I have tested the scenario in SXI_MAPPING_TEST by making the following changes in IR and ID.
1. Changed the cardinality to 0 to unbounded in Interface mapping.
2. Have kept the Interface determination type to Enchanced.
I am getting the ERROR" split mapping created no messages" in sxi_mapping_test.
Can anyone help me out on this.Good answers will be rewarded.
Thanks all,
Zabiulla

Prabhu,
what needs to rely on Java stack is the adapter, not the mapping.
Mohammed,
make sure you create Messages/MessageX tags (with proper namespace) in your multimapping. Also, expect these tags in your input mapping.
You can get the exact Messages/Message1 tags (with the namespace) in a message mapping with multiple input or output messages. Create it and go to test tab, just to check the tags you should read/create in your abap mapping.
Regards,
Henrique.

ABAP Mapping and Message Mapping

Hello
I want to do the followig mapping
File - > IDOC
field1 ->field_idoc1
field2 ->field_idoc2
field3 ->field_idoc3
field4 -> (based on an dictionary table in the R/3)
For the first 3 fields I will use message-mapping.
For field4 I heard about ABAP Mapping. Select with the value of field4 in an ABAP Table and response the new value to the mapping back.
Would both mappings in one Interface-Mapping work?
Regards
Christoph

Christoph, There was an article previously available in articles section, now i dont find the link.
I have given a sample code below. You can find lot of sample JCO code provided along with the JCO library that can be downloaded from service.sap.com.
JCO.Repository mRepository;
JCO.Client mConnection = JCO.createClient(
               sapClient,
               userName,
               password,
               language,
               hostName,
               systemNumber );
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "sample", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("Z_TEST");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( param1_value , "P_PARM1");
input.setValue( param2_value , "P_PARM2");
JCO.ParameterList tabInput = function.getTableParameterList();
JCO.Table inputTable = tabInput.getTable("T_PARM3");
inputTable.appendRow();
inputTable.setValue("test" , "IDOC");
mConnection.execute( function );
String ret = function.getExportParameterList().getString( "P_GEN_NUM" );
mConnection.disconnect();
return ret ;

Get Message ID and namespace from ABAP Mapping

Hi XI Expert,
Please advise how to get the message ID and namespace from ABAP Mapping.
Thank You and best Regards
Fernand

Hi,
To access the message ID, use the method GET_MESSAGE_ID of the controller object:
1. Fetch a protocol instance for the protocol IF_WSPROTOCOL_MESSAGE_ID.
2. To have the system return the message ID after the sender has sent a request message or the receiver has received a request message, use the method GET_MESSAGE_ID of this instance. This returns the ID by using the parameter MESSAGE_ID of type SXMSGUID.
Also you could do the same by this way also:
IF_WSPROTOCOL_XI_HEADER
has attributes messageid and interface namespace.
using this you can read the XI message header

Hi
Mapping Techniques
XI provides 3 standard ways of interface mapping between source and target.
Graphical mapping
Java Mapping
XSLT Mapping
Two more additional mapping types can be activated in XI by making changes to the exchange profile. Those two mappings are
ABAP mapping
XSLT mapping with ABAP Extensions
Graphical Mapping
Graphical mapping is a common approach followed by everyone for generating desired target structure. It involves simple drag-n-drop to correlate respective nodes (fields) from source and target structure. It hardly involves coding. (Exception - User defined functions). But sometimes with graphical mapping it is difficult to produce required output. For example ... text/html output, namespace change, sorting or grouping of records etc.
ABAP Mapping
A person comfortable with Object Oriented ABAP can go for ABAP mapping instead.
Java Mapping
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.
XSLT Mapping
One can also think of Java mapping as another option but it is a bit complex and required knowledge of Java. In such cases, XSLT mapping can be the best approach to meet the requirements.
A few example cases in which an XSLT mapping can be used:-
When the required output is other than XML like Text, Html or XHTML (html displayed as XML)
When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
When data is to be filtered based on certain fields (considering File as source)
When data is to be sorted based on certain field (considering File as source)
When data is to be grouped based on certain field (considering File as source)\
Advantages of using XSLT mapping
XSLT program itself defines its own target structure.
XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.
XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
File content conversion at receiver side can be avoided in case of text or html output.
Multiple occurrences of node within tree (source XML) can be handled easily.
XSLT can be used in combination with graphical mapping.
Multi-mapping is also possible using xslt.
XSLT can be used with ABAP and JAVA Extensions.
Disadvantages of using XSLT mapping
Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.
XSLT mapping requires more memory than mapping classes generated in Java.
XSLT program become lengthier as source structure fields grows in numbers.
XSLT program sometimes become complex to meet desired functionality.
Some XSL functions are dependent on version of browser.
Different types of Mappings
MAPPING SUPPORTED BY XI
Message Mapping -> Graphical Design and testing environment. Default Provided By XI. Queue based modelling allow handling or large documents. Extensible via user defined functions
XSLT Mapping - > Based on openstandard, Portable across application platform, Extensible using user defined functions kewl but disadvantage is Memory overload while handling large documents.
SAX -> Simple Api For XML. -> Allows you to parse through a XML document. Doesn't consume any memory. But the message can be parsed only once from top to bottom. It Has evolved by contributions made by group of ppl itz a open architecture.
DOM -> Document Object Model -> Itz designed by W3C. Consumes Memory as the message will be loaded. Allows parsing of document in both way top down and bottom up.
Send me your email id.Shall send you very good docs for both ABAP Mapping and message mapping.
Thanks
