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 Hierarchy Table Into Tree (Java WebDynpro)

Hello all,
 I have a requirement of showing a MDM Hierarchy Table into Tree UI element.
These are the steps am following:
1) MDM Connectivity
2) Using RetrieveLimitedHierTreeCommand command to retrieve tree structure of the table
3) Using getChildren() method of each node to get the children
4) Made a tree ui element with a recursive node
Now since the Hierarchy table can reach any level of nodes how do i write code for dynamic tree node/leaf generation?
Please guide me through with detailed steps/code if possible?
Regards,
Yogesh Bhatia

Hi Yogesh,
After getting the HierNode you have to recursively populate the hierarchy tree using the below code:
private void createHierarchyTree( parent_element, com.sap.mdm.data.HierNode HierNode)
 if(HierNode != null && HierNode .getChildren() != null)
 for(int iChildCount=0 ; iChildCount < HierNode .getChildren().length ; iChildCount++)
 IPublic<comp name>.Iparent_element objTreeElement = parent_element.node<Recursive node name>().create<name>Element();
 objTreeElement.setattr1(HierNode.getChildren()[iChildCount].getDisplayValue());
 objTreeElement.setattr1_Recid(HierNode.getChildren()[iChildCount].getId().id);
 parent_element.node<Recursive node name>().addElement(objTreeElement);
// call the method recursively
createHierarchyTree(objTreeElement, HierNode.getChildren()[iChildCount]);
This will populate the tree, you need to create an action in the tree view and link it to TreeNode Type action property using which you can get the selected value.
Hope this helps!!
Cheers,
Arafat

Editing Tree UI for MDM Hierarchy tables ina WDJ application

Hi ,
We have a requirement where MDM hierarchy tables are displayed using a tree UI in WDJ application.
However, tree UI is used only for the display purpose. Is there anyway or any other UI available
using which we can achive edit option in the tree as well?
Not only this, we are supposed to provide functionality to support moves across the nodes of hierarchy.
Like PC move or SBU move from one hierarchy to another.
First of all, can we achive this in WDJ or MDM WebDynpro COnfigurator? If we can, then how? Any links or pointers for this?
Thank You,
Apoorva Dave

You could use a Tree UI element together with a detail view for editing the selected tree node. Or you could use a "TreeTable" which is a Web Dynpro Table with a TreeByNestingTableColumn.

i think u can use the method addNodeType (IWDAbstractTreeNodeType nodeType, int index) to add/edit an element at a particular index in the tree.
but drag drop features i think are not supported in standard WD and u need to use a java script in the view to achieve this ?

Problem while populating RFC table into HTMLB tableView control

Hi, We are trying to populate some data from R/3 into the front end. For this we are using tableView control in HTMLB. But the problem is, one particular field is behaving strangely where as all other fields are displayed correctly. This value is sometimes displayed correctly and sometimes not. The FM if executed at the back end is giving correct result always. In Java there is a single line code i.e. table.getString("FIELD_NAME_IN_RFC");. Please guide us to find out the problem if somebody has already faced this before.

Develop MDM Heirarchy table using Webdynpro Tree

Hi
Can anyone let me know how i can build a MDM Heirarchy table using webdynpro tree.
Thanks

Can you be more specific? Is your problem with MDM or Web Dynpro? And what do you mean by "build an MDM Hierarchy Table"?

Can we import multiple language descriptions in Hierarchy tables of MDM

Hello Experts,
I am using MDM 7.1 SPS4 and working on the Vendor Repository standard content.
My source file of Regions table contains data in multiple languages for each region record. All the required destination language fields have been mapped properly in the standard map. Import action is set to 'Create' for new records and 'Update Mapped only fileds' for existing records. Matching criteria has Name<English> filed defined in it.
However, after importing these hierarchy records, in data manager only the Name description of English is populated while all other language descriptions for the same record is shown in Red (i.e not populated with the expected data).
Is this a limitation of MDM itself or am I missing some setting?
Thanks in advance,
Elizabeth.

Hi Elizabeth,
steps for importing into hierarchy tables
To add new multilingual records:
1 If necessary, create the hierarchy from the current language layer Name field that contains the hierarchy information (e.g. using the Split Hierarchy command).
2Map the current language layer Name field and then Map/Add the entire set of hierarchy values.
3 Map the other language layer Name field(s). No value mapping is necessary.
4 Map the [Remote Key] field.
5 Record match using: (a) the Name field; (b) the [Remote Key] field (if the Name field was not value mapped); or (c) the combination of both.
To update the language layer of existing records:
Map the other language layer Name field(s). No value mapping is necessary.
Map the [Remote Key] field.
Record match using the [Remote Key] field and set the import action to Update (All Mapped Fields).
Just try and if you need any other info then please get back to me.
Thanks,

Tree view control - populating speed - over 100 nodes

I have a few questions about a tree view control:
1. If you put more than approximately 100 nodes in a tree, it populates too slow. There is no change if you try with query or record group. I figured that the populating of the record group makes all problems, but there is no chance to enlarge the array siye of the record group. Developer 6 has some built-ins which can do that, bu after many unsuccesful tries I don't see a solution.
I tried to make fetches from cursor into a record group (30 nodes on a "page", but it looses a real hierarchy and you should do a lot of programming). If anybody knows how to make the population of the tree faster or have some template / please forward.
2. After we put the patch 5 of developer6, tree view control is totally unpredictable. Usually its when you programmaticaly try to select a node (ftree.set_tree_selection)...Anybody have the same problems?

Try taking out the 'start with' and 'connect by' clauses in your select statement if you're using them. However, this will mean that you will have to determine the levels of the tree manually and ensure that the data comes out in the same order each time you execute the select statement.

Has any body worked with below senario to create a Hierarchy table through Import Manager. If so how did you do it?

Hi SDN Powered,
For Hierarchy Table - Parent/Child Value Pairs w/o Node Name just do as follows:
1) In the Source Hierarchy tree, select the Parent and Child field nodes which you want to use to build hierarchy.
2) Right-click on one of the nodes and choose Create Hierarchy Field from the context menu, or choose Source > Create Hierarchy Field from the main menu.
3) MDM opens the Create Hierarchy Field dialog box. This dialog box contains 4 feilds, viz Hierarchy Field Name, Parent Field, Child Field, and Node Name Field. In the Hierarchy Field Name, type the name for the new field.In the Parent Field, Child Field. For Parent/Child Value Pairs w/o Node Name , set the Node Name Field to None.
4) Click OK to close the Create Hierarchy Field dialog box. The MDM Import Manager creates Hierarchy using the values you have provided.
I hope I am able to solve your problem.
Thanks & Regards

My problem is
1) i want to import the data in the corresponding fields
2) at the same time after importing, i want the data of the this fields should appear as a parent child relationship in the data manager.
if any one know the solution for this , please explain in step by step process.
if you have any PDF's on every Import operation in the MDM please provide to me.
It will be greatful for me.
Thanks in Advance.......

Hi bharat,
if your source data is like this ex:
1. Consumables & Maintenance Solutions;Cleaning, Freshening & Softening;Cleaners;Cleaner Compounds
2. Hand, Power, Machine, & Measuring Tools;Assembly & Fastening;Wrenches;Manual Wrenches;Manual Wrench Parts & Accessories
you can follow this process:
1. select the category and right click, in the context menu set the split delimeter, in that choose split hierarchy.
2. select the category and right click, from the context menu select split into hierarchy.
3. In Map fields/values tab, in source fields you will see new split hierachy field, map this field to corresponding destination cateory field.
4. in values pane, you can see the source values in a hierarchy.
5. Map these values to the corresponding destination values, other wise you can add to the destination in a new category, ( select the source values node and click on add button and you can selcect Add branch as child Or Add branch as sibling)
6. Once value mapping is over, do the importing and you can see these results in Data manager Taxonomy mode.
as you said: you have data like field1 field 2 field 3
You have to select all the fields in Import Manager which u need to hierarchies and select the option Create Hierarchy field . You will see a new popup window in which you have to fill the fields like ( parent field/ child filed and node) and your hierarchy will be created.
hope this may help You,
