MDM com API: Retriving Attribute priority in C++

Has anyone been able to retrive attribute priority using C++ in MDM 5.5sp3? We're in the process of upgrading from mdme4 to 5.5sp3 and the code that has worked for us in the past is failing to return the priority value:
unsigned char ucPriority;
ucPriority = a2iAttribute->Priority;
(Where a2iAttributre is a valid IAttribute object)
Is now always returning a value of 0 irregardless of the true value of the priority.
When we access the priority in either VB 6.0 and c# (.net 1.1) it works fine.
We're using build 5.0.28.17 from Jan 17th, 2006.
Any ideas?
Thanks,
-glenn

It turns out this problem occured only when we tried accessing an attribute's priority via icatalog.GetLimitedAttributes.
Many thanks to Nick Luu and Stanley Levin at SAP for their help in narrowing down on the exact problem and getting it fixed in time for the release of mdm 5.5 SP3 Hotfix 5 on 8-11.

  • MDM COM API Installation

    Hi All,
    How can we install MDM COM API on the server. I mean what are the requirements.
    I have to run MDM UOM manager for which it is required.
    Thanks
    Devinderpal Yadav

    Hi,
    first of all you should consider installing the COM API and the UOM Manager on a client machine as it is a client software.
    1. Download COM API from service marketplace
    2. Copy the installer to the according server / desktop pc
    3. Start installation
    Prerequsite:
    Runs only on windows platforms (as a matter of course due to the fact that it is a COM lib).

  • COM API Product attributes

    I'm using the COM API with C# to develop a web application.
    I have a list of products on a web page. When someone clicks on the product I would like to show some, not all, of the attributes.
    How can I retrieve the value of a particular attribute?

    If I try the following I always get "Incorrect parameter". If I pass the index of the attribute, it works. Will this not work for attributes with spaces in their name?
    XCATCOMLib.Search search = new XCATCOMLib.SearchClass();
    XCATCOMLib.ResultSetDefinition productsRsDef = null;
    XCATCOMLib.Tables tables = catalog.Tables;
    XCATCOMLib.Table prodTable = tables.Item(PRODUCT_TABLE);
    productsRsDef = new XCATCOMLib.ResultSetDefinitionClass();
    productsRsDef.Table = prodTable.Name;
    productsRsDef.IncludeAttributes = true;
    productsRsDef.ShowEmptyAttributes = false;
    for (int j = 0; j < prodTable.Fields.Count; j++)
       productsRsDef.Fields.Add(prodTable.Fields.Item(j));

  • MDM ABAP API - Language information not valid for repository

    Dear all,
    We're programming an interface in SAP R/3 to MDM catalog through 'MDM ABAP API's'. Automatically, it creates an RFC connection to MMD, but we're getting the following connection errorwhen executing the API:
    E MDM_ABAP_API         078 Language information ENG US USA not valid for MDM repository XXXYYYZZZ*.
    *where XXXYYYZZZ is the repository name. 
    W'e've established the connection in R/3 through transaction MDMAPIC and we've created the same user in R/3 and MDM Console.
    This is the code written on the program where we are defining the language (ENG), country (US) and region (USA).
    *maintain logon language information
    ls_repository_language-language = 'ENG'.
    ls_repository_language-country = 'US'.
    **no region information needed here
    ls_repository_language-region = 'USA'.
    How can I see the repository language definition?
    Which are the correct codes to be used for language 'English', Country 'United States' and Region 'USA'?  And for other countries, like spanish language, country Spain and Region ¿spain?
    In fact, we copied this code from website:
    http://help.sap.com/saphelp_nwmdm71/helpdata/en/44/93ad8931381053e10000000a422035/frameset.htm
    Maybe the problem is that any RFC configuration is missing, and it has to be done in transaction SM59?
    Thanks for your feecback,
    Carlos Santamaría.

    The problem is now solved.
    The correct languague information codes for Language Spanish, Country Spain and Region, are as follows:
    Language: 'spa'
    Country: 'ES'
    Region: '___'
    It is important to respect the CAPS, otherwise it doesn't work.
    Regards,
    Carlos Santamaría.

    Hi Suresh,
    You can have the MDM JAVA API javadocs from the link
    http://help.sap.com/javadocs/MDM/SP06P2/index.html
    There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
    You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
    Right click on project-> properties->Java Build Path - > Add external JARs
    At run time you can add them the reference in
    Right click on project-> properties->web dynpro references->library reference.

    Hi Nitin,
    Thanks for the prompt Response.
    Even I am guessing that its becose of Connection pool.
    I am destroying session as follows
                   DestroySessionCommand destroySessionCommand =
                   new DestroySessionCommand(p_pool);
              destroySessionCommand.setSession(p_repsession);
              try {
                   destroySessionCommand.execute();
              } catch (CommandException e) {
                   e.printStackTrace();
              destroySessionCommand.setSession(p_Uesrsession);
                   try {
                        destroySessionCommand.execute();
                   } catch (CommandException e) {
                        e.printStackTrace();
    But I didnot find any method by which i can close realsse connection from connection pool.
    It would be great if you can help me how close or realese those connection.In MDM Console i am able to see those sessions even after destroying them.
    Regards Shruti.

  • MDM Hierarchy Table Into Tree UI Control in ABAP WebDynpro & MDM ABAP APIs

    Experts,
    I am a newbie to ABAP / MDM ABAP APIs. I am looking into the possibility of using Tree as as a UI control in a webdynpro abap application to represent hierarchy tables, perform hierarchy / taxonomy search, create and update records involving hierarchy fields, using MDM ABAP APIs.
    I would like to seek inputs to check whether and how, is it possible to use MDM ABAP APIs to:
    1. To perform taxonomy search on material table
    2. To Create material records in the main table involving taxonomy fields.
    3. To search on main table records using taxonomy attribute values as search parameters.
    4. To use Tree UI control with in WebDynPro ABAP, to peform above operations.
    We intend to use function modules - service calls from within WebDynPro ABAP applications, hence would like to know the feasibility, actual build effort and complexity of function modules.
    Inputs and advice on same will be highly appreciated and duly rewarded.
    Regards,
    Paras

    1. To perform taxonomy search on material table - if material table is of type Taxonomy then possible
    2. To Create material records in the main table involving taxonomy fields - possible . you create records in main table and assign value of field to that of taxonomy table entry
    3. To search on main table records using taxonomy attribute values as search parameters. - possiblr
    4. To use Tree UI control with in WebDynPro ABAP, to peform above operations. - yes possible
    dont mix between hierarchy table and taxonomy table
    they are diff in MDM , but it is possible to build UI with WD tree element for each of these types.
    all that you said are supported in ABAP APIs
    thanks

  • MDM Java API guide

    Do any other guides about MDM Java API exist (except MDM_API_Tutorial and MDM 5.5 SP05 - Java API Migration Guide.pdf) ?
    Especially MDM Search Java API interesting.
