ABAP API and Key Mapping

Hello there,
I am trying to use the MDM 7.1 ABAP API to access MDM data from within a BI system.
Now I am wondering how to access key mapping for records in the Main Table.
In the Java API there is the RetrieveRecordsKeyMappingsCommand which returns all key mapping information for a list of record IDs. But I cannot find something similar in the ABAP API.
Who knows where to start?
Thanks for hints
Ingo

Hi ,
In ABAP API also you can retrieve key mapping of main table records using function 'MDM_API_RETR_CLIENT_SYS_KEYS'.
You will get details of this function in sap library or ABAP API documentation provided by SAP.
For any further queries kindly reply.

Intercompany and Key Mapping Price List

Hi expert,
I have the Intercompany Add-ON version 2.0.8.30 installed on a SAP Business One 9.0 PL15 for 4 localization:
Head Office (H000): IT
Branch 001 (B001): FR
Branch 002 (B002): DE
Branch 003 (B003): CH
This is the scenario:
I started two weeks ago without Key Mapping the Price List because the first choice was that to use different price lists for each country.
Now, I need to replicate the H000 price lists in new created rice List in each brench.
We created new Price lists named "ZZ IT 01", "ZZ IT 02" and so on and we Key Mapped them.
Here the screenshot for Key Mapping:
Problem is that:
NO REPLICATION APPENS!
The Mapping was created 1 week ago but NO syncronization appened...
So, the question is: How I can syncronize the Price Lists?
thanks in advance,

MDM API for key Mapping.

Hi All,
Can anyone tell me how to use MDM API for updating key mapping ?
I want to create a webservice which will take customer,client system and key for updating key mapping in mdm.
Can anyone give me clue on this

Hello Rama:
Under Java you can do these things:
Delete key mapping:
CatalogData.DeleteKeyMapping(ClientSystem : String, Table :
String, RecordID : int, Keys : String[])
Argument Description
ClientSystem -> Client system name
Table -> Table name
RecordID -> Record ID
Keys -> Remote keys to remove
Set a new keymapping:
CatalogData.SetKeyMapping(ClientSystem : String, Table :
String, RecordID : int, Keys : String[], DefaultKeyIndex
: int)
Argument Description
ClientSystem ->    ClientSystem name
Table ->           Table name
RecordID ->        Record ID.
Keys ->            Remote Keys you want to add
DefaultKeyIndex -> Index entry into the key parameter
indicating the key value as the default.
I hope that helps

SAP MDM 7.1 Vendor Number and key mapping

We are importing data for vendors whcih DO NOT have any VendorNumber now. (they have some the VendorNumber but not one which can be used in the field Vendor Number.)
We have to generate the VendorNumber during oar - better - after the import.
There is not problem creating is after the import with a simple assigmment statemen which contains some rules.
So far so good.
The pitfall in creating the number AFTER the import is that NO remote keys are generated.
Any idea how to create these keys AFTER or DURING import IF hte venoder number is assigned during or after import?

Hi Lutz-Peter,
Any idea how to create these keys AFTER or DURING import IF the venoder number is assigned during or after import?
During Import, if you have local keys for each of these remote system, you can maintain it using Remote key concept.
But you must have one Matching field(Global ID) for this. Since you are creating Vendor key centrally in MDM using MDM Data Manager. Are you exporting data to different remote systems after creating Vendor number centrally in MDM(which can acts as Global ID) If yes then after data created into Remote systems, you can bring Local ID of remote system with this Global ID during import. 1stly, for this your main table property Key Mapping = yes should be enabled in MDM console.
So during import you should open MDM Import Manager by selecting required Remote system, you will get one more field in target Remote Key, map this target field with with source Local ID field along with other fields like Global ID etc. So in this you will have your Remote Key for Remote systems.
However Remote Keys depends on how are you creating Local ID(remote Keys) for remote systems, i mean in Remote systems itself or through MDM Syndicator using Remote system Key Generation concept.

ABAP API Connection Problem

Hi folks,
I am working with the MDM ABAP API and there are some errors that do not make any sense to me.
Here is a list with the technical information:
MDM 5.5 SP 5 (5.5.40.83)
SAP NetWeaver 2004s (700)
MDM API 555/700
I have set up the Repository information in MDMAPIC, using a new created provider of the type CL_MDM_PROVIDER_55_SP05_PL00 ( MDM5.5 SP05 Patch 0, Server Build 5.5.40.79 - 5.5.40.xx ).
I then have tried to establish the connection to the server and repository and so on according to the HowTo Guides.
When I finished yesterday, I managed to connect to my local MDM Server and to retrieve the names of the mounted repositories, but I was not able to retrieve records from a certain repository. When I wanted to solve that problem today, I was not able to connect to my MDM server anymore. There have been no changes in the coding or the configuration since then, only the MDM server has been restarted and the repository has been reloaded. But apart from that, nothing has changed but still I am not able to establish the connection anymore ( Connection refused ). Then I have tried to connect to another MDM server, but there I get another error ( Connection is not trusted ), although I have rechecked a dozen times that there is the allow.ip with the proper ID of my SAP system and the according user in the MDM repository.
From time to time, the errors change without changing anything else, just by trying to execute it a couple of times. I have figured out, that sometimes I get an error out of the above mentioned provider class ( CL_MDM_PROVIDER_55_SP05_PL00 ). Is it possible, that the MDM API is not working properly with the PL00?
Hints are appreciated a lot...!
Thanks and best regards,
Sabine

Hi,
Check whether the server is down or not. If the server is down, u will get the same error message

ABAP API for MDM work flow

Hi SDN,
I need some information related to ABAP API for MDM workflow. I did search in SDN and I found one solution in a thered posted on Jul-2008.
ABAP API - MDM Workflow execute
My dought is: Do we have any ABAP API for call MDM work flow. Please provide me the solution ASAP. Apprciate for your immediate response.
Regards,
Kumar.

Hi LAKSHMAN ,
To answer your question specifically
Using ABAP api you cannot call MDM workflows as of mdm 5.5 there are no functions specific to calling MDM workflows in ABAP.If you want to implement workflows on ABAP side you need to go for SAP ECC workflows which is a different topic than MDM>
To call MDM workflows over the Java stack ie WAS (SAP portal),You have 2 ways
- UWL
- Guided Procedures.
- UWL is a way of calling MDM workflows on EP.Wherein the workflow design will be done in MDM and it will only be called in portal using appropiate connections and configurations.
You can refer the below links to know more on them:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/771f1a61-0e01-0010-daa9-93a52905da09 (uwl)

- GP is a way where by you need to design the entire workflow on SAP portal the logic can be pertaining to MDM but the design is completely on portal using webdynpros and api.
You can refer the below links to know more on them:

Java ,abap and XSLT mapping

Hi all,
can any one provide some material on java ,ABA and XSLT mapping(as i got requirement on my current project)..
thanks in advance.
regards
krish..

Hi
All mapping related links
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 any complex logic.
Java and XSLT mapping are used when graphical mapping cannot help you and you have multilevel hierarchy structure data.
When the choice is between Java and XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. One among them being that you cannot use Java APIs and Classes in it. There might be cases in your mapping when you will have to perform something like a properties file look up or a DB lookup, such scenarios are not possible in XSLT and so, when you want to use some specific Java API's you will have to go for 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 exactly easy to develop either.
To know more about each of them please go thru the following links. And if you ask me your which is better, it depends basically on the scenario you implementing and the complexity involved. Anyways please go thru the following links:

ABAP and Java mapping

Wanted to confirm my understaing for ABAP and JAVA mapping.
Am I correct in my assumption that these mapping techniques can be used only if input and ouput is in XML format ?
So if XI is receiving a flat comma separated text/non-XML file or an IDOC for that matter and output is NOT in XML format, say again flat text file or IDOC, I cannot use above two techniques?
All the docs I have read suggest that 'Execute' method is called when XML file/data is received, paresed using DOM/SAX/JAXB (for Java mapping) or IXML lib (for ABAP mapping) and then create a output XML file.
-Thanks in advance

Hi Bob,
Here you have a code sample for deescaping. I have have written this code a couple of time ago. The incoming file can be any text format. It might be XML, but not necessarily.
The main method is not reqired, but good for testing.

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

Remote System and Remote Key Mapping at a glance

Hi,
I want to discuss the concept of Remote System and Remote Key Mapping.
Remote System is a logical system which is defined in MDM Console for a MDM Repository.
We can define key mapping enabled at each table level.
The key mapping is used to distinguish records at Data Manager after running the Data Import.
Now 1 record can have 1 remote system with two different keys but two different records cannot have same remote system with same remote key. So, Remote key is an unique identifier for record for any remote system for each individual records.
Now whenever we import data from a Remote System, the remote system and remote key are mapped for each individual records. Usually all records have different remote keys.
Now, when syndicating back the record with default remote key is updated in the remote system that is sent by xml file format.
If same record is updated two times from a same remote system, the remote key will be different and the record which is latest contains highest remote key.
Now, I have to look at Data Syndication and Remote key.
I have not done Data Syndication but my concept tell if there is duplicate record with same remote system but different remote keys both will be syndicated back. But if same record have two remote keys for same remote system then only the default remote key is syndicated back.
Regards
Kaushik Banerjee

You are right Kaushik,
I have not done Data Syndication but my concept tell if there is duplicate record with same remote system but different remote keys both will be syndicated back.
Yes, but if they are duplicate, they needs to be merged.
But if same record have two remote keys for same remote system then only the default remote key is syndicated back.
This is after merging. So whichever remote key has tick mark in key mapping option(default) , it will be syndicated back.
Pls refer to these links for better understanding.

Problem with childs nodes and automatic key mapping in a Data Object

Hi experts!
I'm doing the service order tutorial from the mobile help at [this link|http://help.sap.com/saphelp_nwmobile71/helpdata/en/21/9b5b924c3b434fba4767731794b029/frameset.htm] and I have a problem...
In the topic "Modeling the Equipment Data Object", says you have to mark the "Automatic Key Mapping" checkbox. So when I had to create a third child node ( the location node ) the system raised an exception with the message "Deselect automatic key mapping flag for more than two-level nodes". I'm trying deselecting the flag and creating the location node, but when I want mark again the automatic key mapping flag, this is disabled.
What can I do to solve this and create the three child nodes with the flag marked? It's a configuration thing?
Any help it's very welcome. Thanks in advance.
Best regards,
Simon.

The thing is: Its not allowed to use automatic keymapping if you have more than two levels. This is why the message showed up, and this is why its been disabled.
What automatic keymapping does: Figures out automatically which child node belongs to which parent (by guessing from the field name and type, which fields in the child correspond to which key fields of the parent).
On three levels, this becomes more complicated => Its disabled.
How to do keymapping yourself instead of having the DOE do it automatically: Do 'Explicit keymapping' from each child to its parent. Explicit keymapping is done by clicking on the corresponding menu button in the child node. Here you need to associate child node fields (they need not be key fields of the child, but they are allowed to be that as well) to each of its parent nodes key fields (so that each child can be associated to its parent).

MDM API to read the Record Key Mapping table

Hi,
Does anybody know what class/method I can use to read the Record Key Mapping table?
For the Business Partner table the Key Mapping table has this columns:
Default / MDM Partner ID / Remote System / Key
I have everything but the Key. How can I read it?
Thanks in advance,
Diego.

GetKey Mapping is one of the available Web Services as of SP4.
Else you could use the Java API to get the Key Mapping.
CatalogData class has the following method
GetKeyMapping
public java.lang.String[][] GetKeyMapping(java.lang.String agency,
 java.lang.String table,
 int[] recordIDs,
 boolean isDefaultKeyOnly)
 throws StringExceptionRetrieves the key mapping for each record.
Parameters:
agency - the agency name.
table - the table name.
recordIDs - the list of records.
isDefaultKeyOnly - True to retrieve only the default value, False to all key values.
Returns: the key values for each record.
