Sorting in Message Mapping

Hi,
My interface (JDBC to File) from source side I am having 3 fields and from target side I am having 2 fields.
Thing is that if third field (Unbranded Material Number) having some value then we have to create new record from target side with plant and product. I am able to do that with Context Change..
I am getting the proper o/p but not in proper format.
I/p
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Plant2product xmlns:ns0="urn:bp:xi:dwn:re:cbt:alps:planttoproduct:100">
 <Item>
 <PLAN>1</PLAN>
 <MATERIAL_NO>2</MATERIAL_NO>
 <UNBRND_MATERIAL_NO>3</UNBRND_MATERIAL_NO>
 </Item>
 <Item>
 <PLAN>a</PLAN>
 <MATERIAL_NO>b</MATERIAL_NO>
 <UNBRND_MATERIAL_NO/>
 </Item>
 <Item>
 <PLAN>x</PLAN>
 <MATERIAL_NO>y</MATERIAL_NO>
 <UNBRND_MATERIAL_NO>z</UNBRND_MATERIAL_NO>
 </Item>
</ns0:MT_Plant2product>
O/p which is coming
<MTPlanttoproductPROS>
 <Plant_Product_Record>
 <PLANT>1</PLANT>
 <PRODUCT>2</PRODUCT>
</Plant_Product_Record >
 <Plant_Product_Record>
 <PLANT>a</PLANT>
 <PRODUCT>b</PRODUCT>
</Plant_Product_Record >
 <Plant_Product_Record>
 <PLANT>x</PLANT>
 <PRODUCT>y</PRODUCT>
</Plant_Product_Record >
 <Plant_Product_Record>
 <PLANT>1</PLANT>
 <PRODUCT>3</PRODUCT>
<Plant_Product_Record>
 <PLANT>x</PLANT>
 <PRODUCT>z</PRODUCT>
</Plant_Product_Record>
</MTPlanttoproductPROS>
I want O/p something like that
<MTPlanttoproductPROS>
 <Plant_Product_Record>
 <PLANT>1</PLANT>
 <PRODUCT>2</PRODUCT>
</Plant_Product_Record >
 <Plant_Product_Record>
 <PLANT>1</PLANT>
 <PRODUCT>3</PRODUCT>
</Plant_Product_Record >
 <Plant_Product_Record>
 <PLANT>a</PLANT>
 <PRODUCT>b</PRODUCT>

 <PRODUCT>y</PRODUCT>
<Plant_Product_Record>
 <PLANT>x</PLANT>
 <PRODUCT>z</PRODUCT>
</Plant_Product_Record>
</MTPlanttoproductPROS>

Hi Anuj,
I have resolved your mapping issue using 3 UDFs.
1.Context NodeUDF
 This UDF used to derive Plant_Product_Record node in Target.
UNBRND_MATERIAL_NO -> NodeUDF -> removeContexts->Plant_Product_Record
 UDF Code:-
 if((a[0].trim()).equals(""))
 result.addValue("");
else
 for(int k = 0;k< 2;k++)
 result.addValue("");
2. Context PlantUDF
This UDF used to populate values in PLANT element in Target.
 PlantUDF takes 2 inputs - PLAN and UNBRND_MATERIAL_NO from Source
2 inputs ->PlantUDF->PLANT(Target)
 UDF Code:-
if((b[0].trim()).equals(""))
 result.addValue(a[0]);
else
 result.addValue(a[0]);
 result.addValue(ResultList.CC);
 result.addValue(a[0]);
3. Context ProductUDF
This UDF used to populate values in PRODUCT element in Target.
 PlantUDF takes 2 inputs - MATERIAL_NO and UNBRND_MATERIAL_NO from Source
2 inputs ->ProductUDF->PRODUCT(Target)
 UDF Code:-
if((b[0].trim()).equals(""))
 result.addValue(a[0]);
else
 result.addValue(a[0]);
 result.addValue(ResultList.CC);
 result.addValue(b[0]);
Please let me know if you have any doubts in this solution.
Cheers,
Jag

I need to sort the incoming file contents before message mapping

Hi All,
I have requirement like i have to sort the file contents before message mapping in Xi. is there any option please suggest me with your value information.i dont want to sort in message mapping before that i want file contents to be sorted order.waiting for your quick reply.
Thanks,
seshagiri

Hi,
You can do this in one scenario.
Lets say you have MT_Source and MT_Target as two message types.
Now your MM1 will be between MT_Source & MT_Source, that is same message type. Here you built your sorting logic.
Now create MM2, between MT_Source & MT_Target. Here your actual mapping logic will be implemented. The input payload for MM2 will be sorted data.
Now in operation mapping, first call MM1 and then call MM2 (You have a plus + sign to add multiple mapping programs). Due to this sequence, at run time first MM1 will be executed and after that its oupt will be given to MM2 as source payload.
Hope its clear. Plz let me know if you have any doubts.

Ihave to map by following rules:
1. Sort output message by taking inputmessage Details- Manager
2. Have to count totla no of employee of respective manager
3. have to check how many department under that manager.
Thanks in advance.

Unable to save the message mapping

Hi..
I have completed the Message Mapping. when i am trying to save the Message Mapping i am getting the Error while executing save "The length 0 of the array ' Sorted Function keys' is not equal to the number of 1 functions".
can you pls suggest me, how can i rectify this type of strange error.
Regards,
Prasad

Hi,
that means that one of your Sorted Functions does not have correct input
as the error says
you probably placed it in a wrong way - check the functions
desciption on help.sap.com or an example on SDN blogs
and correct it - then it will work

Message Mapping error: RuntimeException in Message-Mapping transformation

Hi,
Being new to XI, I am struglling to sort out a basic mapping error. Appreciate if you could help out.
Its an File->XI->R/3 scenario.
My FCC successfully reads the File and creates an XML. However this XML is not transferred to the target XML structure which is exactly same except the root element name is different at top.
I tried various forum tips but I still am getting the error.
( When I Test the Message mapping in test mode..it seems fine, however if I copy the XML from SXMB_MONI, it then throws the above error)
I looked at the MM in text mode: below is the extract
/ns0:MT_REQUEST_TO_SAP/REQUEST_DETAILS/MSG_HEADER=/ns0:MT_REQUEST/REQUEST_DETAILS/MSG_HEADER=
/ns0:MT_REQUEST_TO_SAP/REQUEST_DETAILS/MSG_HEADER/SOURCE=/ns0:MT_REQUEST/REQUEST_DETAILS/MSG_HEADER/SOURCE=
/ns0:MT_REQUEST_TO_SAP/REQUEST_DETAILS/MSG_HEADER/DESTINATION=/ns0:MT_REQUEST/REQUEST_DETAILS/MSG_HEADER/DESTINATION=
/ns0:MT_REQUEST_TO_SAP/REQUEST_DETAILS/MSG_HEADER/MESSAGE_ID=/ns0:MT_REQUEST/REQUEST_DETAILS/MSG_HEADER/MESSAGE_ID=
As seen the name space in both starts with nS0 and end of each line has '=' sign. Is that ok.
I have run out of options and dont know , whats the problem. Please help.
The target and Source XML structures are exactly same as shown below
MT_REQUEST MT_REQUEST_TO_SAP
 |__MSG_HEADER |__MSG_HEADER
 |__SOURCE |__SOURCE
 |__DESTINATION |__DESTINATION
 |__MESSAGE_ID |__MESSAGE_ID
And the SXMB_MONI Trace shows the following error
<Trace level="1" type="T">com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation:
Cannot produce target element /ns0:MT_REQUEST_TO_SAP.
Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at ..
Thanks

Hi Prakasu,
As structure are exactly same, I have done 1:1 mapping. So all the fields in target structure are mapped, so no field has beeen left.
In this structure, I do not have any 1:n relation. So 1:1 mapping should be fine.
Apart from this could teher be any other reason.

How do I create a new record for all unquie combinations of KOSTL and POSID? And total the FTE field for each line? Can this be done in a message mapping?

Hello,
How do I create a new record for all unquie combinations of KOSTL and POSID? And total the FTE field for each line? Can this be done in a message mapping?
Yes, very much possible with or without UDF. See sample mapping below without using UDF:
For ROW:
KOSTL(set context to row) -> concat: -> sort: case insensitive ascending -> splitByValue:valueChanged -> collapseContext -> ROW
POSID(set context to row) -> /
For KOSTL:
KOSTL(set context to row) -> concat: ----------------> sortByKey: case insensitive ascending -> formatByExample -> collapseContext -> splitByValue:eachValue -> KOSTL
POSID(set context to row) -> / KOSTL(set context to row) ->/ /
KOSTL(set context to row) -> concat: -> sort: case insensitive ascending -> splitByValue:valueChanged -> /
POSID(set context to row) -> /
For POSID:
KOSTL(set context to row) -> concat: ----------------> sortByKey: case insensitive ascending -> formatByExample -> collapseContext -> splitByValue:eachValue -> POSID
POSID(set context to row) -> / POSID(set context to row) ->/ /
KOSTL(set context to row) -> concat: -> sort: case insensitive ascending -> splitByValue:valueChanged -> /
POSID(set context to row) -> /
For FTE:
KOSTL(set context to row) -> concat: ----------------> sortByKey: case insensitive ascending -> formatByExample -> sum -> splitByValue:eachValue -> FTE
POSID(set context to row) -> / FTE(set context to row) ->/ /
KOSTL(set context to row) -> concat: -> sort: case insensitive ascending -> splitByValue:valueChanged -> /
POSID(set context to row) -> /
Hope this helps,

Caching values between different executions of a message mapping

Hi all
Like global container object is used for caching values between different user defined functions
within the same message mapping.
Can v have some sort of cachingvalues
between simultaneos exceutions of same message mapping?
Thanks and Regards
Bhasker

Hi Bhasker raj,
This facility is there if you are using seeburger adapters.
YOu can use something called seeburger variables which can hold the data beyong the mapping in some permanent memory.
Alternatively, you can think of creating a ZTABLE in the ABAP stack of XI and storing the data you want in it, using a UDF and get it back in another UDF.
YOu can use the first UDF at last node/field in the message mapping and the
secomd UDF in the first node/field in the mapping.

Require a Message mapping for this Logic.

Hi Experts,
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field in the Target Side. ike wise the process goes on upto 3.Kindly do the needy..
Thanq very much in advance..
Edited by: Prashanth Bharadwaj on Oct 17, 2011 1:29 PM

Hi Prashanth,
Concatinate the two fields OrderNo and MaterialNo and follow the below logic which will resolve your problem.
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext-->IDOC
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext>splitByEachValue>subString(0,1)-->Delivery_Order_No
formatByExample>collapseContext>SplitByEachValue-->Recv_Date
FormatByExample:
input1:resulrOfSortByKey
input2:concatination>removecontext>sort-->SplitByValuChange
sortByKey:
input1:concatination-->removecontext
input2:date-->removecontext
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext>splitByEachValue>subString(1,1)-->Material_Num
formatByExample>sum>Recv_Quantity
FormatByExample:
input1:sortByKey
input2:concatination>removecontext>sort-->SplitByValueChange
SortByKey:
input1:concatination-->removecontext
input2:Quantity-->removeContext

Need Help with Message Mapping in PI 7.1 - JDBC to IDOC

I have an outgoing SQL function that sends multiple rows of data for use in creating an IDOC in ECC. I am trying to key the creation of new IDOCs (already did the maxOccurs trick to the IDOC definition) based on a field in the JDBC return data...
JDBC Message Format...
SEGNAM - TRANS_ID - MATERIAL - VKORG...ETC
MARA - 00001 - 1234 - <space> - ...
MARC - 00001 - 1234 - VK01 - ...
MARA - 00002 - 9876 - <space> - ...
MAKT - 00002 - 9876 - <space> - material description - ...
Each time there is a new TRANS_ID, I need to indicate a new IDOC in the message mapping. I have tried all kinds of combinations of TRANS_ID --> dropContext --> splitValue and TRANS_ID --> collapseContext --> splitValue, but nothing has worked.
Has anyone done this kind of message map (without any BPM please)?
Thanks,
Nathan

Hello Nathan,
For this one, you have to play with contexts.
row 1 SEGNAM = MARA, TRANS_ID = 1, MATNR = 123...
row 2 SEGNAM = MARC, TRANS_ID = 1, MATNR = 123, WERKS = PL01...
row 3 SEGNAM = MARA, TRANS_ID = 2, MATNR = 987
This also depends on the occurrence of the parent node. example, if I want MATNR to be populated, the logic would be like
ex:
IDOC1..unbounded) (The logic is the already provided in an earlier response)
-->MATNR (1..1)
MATNR --------> removeContext ----------------> FormatByExample --> MATNR
TRANS_ID --> removeContext --> splitByValue:ValueChange --> /
If the rows are not in order of trans_id, then you need to incorporate sorting into the logic above.
Hope this helps,
Mark

DTW Sort Error - after mapping during import

I got the "Sort Error - after mapping during import" message in DTW. (version 8.8)
I would like to import warehouse info for items.
My itemcodes are fix 15 character numbers, like this: 10204150020011
The note nr. [1331130|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/oss_notes/sdn_oss_sbo_dtw/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d31333331313330%7d] said that I can't use recordkey like this.
Do you have any idea how can I import thees information with DTW?
Thank you,
Attila Sarkady

Dear All
Please give correct and complete information
i have tested every kind of combination;
- recreate the template with the dtw for Items = i have UDF's
- ADD the column RecordKey !!! unbelievable that we have to do this
- i have entered a nr 1 in it (even when we had already 850 items in the database)
(and of course the hints of Gordon - columns as text, start with basic... - and use CSV format)
now at last i can import the record line

Hi , friends pls explain abap mapping and message mapping

1) pls explain abap mapping and message mapping
send me screen shorts also.

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

Error while activating any message mapping in IR: very strange

hi forum i m getting an error in IR while activating any messageMapping.
the error is too long to be posted....i m posting a few lines of that:

Sudeep,
Let we try this way. I'm sure you might have some existing mapping objects in IR.
Try to change that object(Description give some name) and activate again the object.
Reply your results whether you are getting the same error.
One sec before changing the object just test the mapping and change the object.
Best regards,
raj.

Error while activating message mapping

Hi,
We are trying to activate message mappings and getting error as CHECK_EXCEPTION and in error details its showing that usr/sap/server.........................../classpath_resolver/Map.......................no such file or directory.........
What can be the issue?We can activate all other objects(DT,MT,IM,etc)
Best Regards,
Harleen Kaur Chadha

Hi

Error while opening Message Mapping

Hi All,
I have one MM in ESR, IDoc to EDI, it has been developed before, and the interface is working successfully.But when I open this MM in ESR, it given a STOP error with desc as 'For input string: ""'.
and then there is nothing displayed on Screen under Definition,Test and Functions tab of MM.The Signature tab content is visible properly.
I am working on PI 7.1.
Is this issue is because of version comapatibilty or missing object. Please provide your inputs to resolve this issue,
Thanks,
Ruchi

Hi All,
I have checked with my basis team, but they suggested that the patches can not be installed as this problem is happening with single message mapping.
When I open this MM, it gives the same STOP error :For input string: "". and when I click on Message Mapping -> Check button, it prompts a message 'Parameter #ParamName# has the invalid value null'.
Please help me to resolve this.As the mapping itself is not getting loaded, so not getting how to set this parameter value(if it is used in MM).
