Hierarchical table

Hi experts,
I have a hierarchical table. This is a normal Table with a mastercolumn, and the mastercolumn is binded to a recursive context node. The context node has a supply function which reads the data when the tree is selected in the table.
My question is: Is there a was to expand all nodes of the table? As I see this cannot be done, because even if I call the supply function, with the parent element, I cant provide the "node" parameter of the supply function..
Am I right?
Thanks

Hello everyone,
It's possible here is the solution (You start calling this recursive method form an action where you get the root of your tree):
METHOD rec_subobj .
DATA: ls_nodes      TYPE wdr_context_child,
        lt_nodes      TYPE wdr_context_child_map,
        lt_all_nodes TYPE wdr_context_child_map,
        lt_elements   TYPE wdr_context_element_set,
        lref_element TYPE REF TO if_wd_context_element,
        lt_subobj TYPE wd_this->elements_bonus_sub_obj,
        ls_subobj TYPE wd_this->element_bonus_sub_obj,
        lv_counter TYPE NUMC3.
LOOP AT pt_nodes INTO ls_nodes.
*    First set the expanded flag.
    CALL METHOD ls_nodes-node->get_static_attributes_table
      IMPORTING
        table = lt_subobj.
    LOOP AT lt_subobj INTO ls_subobj.
      ls_subobj-expanded = abap_true.
      MODIFY lt_subobj FROM ls_subobj.
    ENDLOOP.
    ls_nodes-node->bind_table( lt_subobj ).
*   We've expanded on the current level, now colect the subobjects and recall this function
    CALL METHOD ls_nodes-node->get_elements
      RECEIVING
        set = lt_elements.
    LOOP AT lt_elements INTO lref_element.
      lref_element->get_static_attributes( IMPORTING    static_attributes = ls_subobj ).
      CALL METHOD lref_element->get_child_nodes
        RECEIVING
          child_nodes = lt_nodes.
*     lt nodes is a hashed table
      LOOP AT lt_nodes INTO ls_nodes.
*       lt_nodes is a hashed table, so we have to change the name :)
        CONCATENATE ls_nodes-name lv_counter INTO ls_nodes-name.
        INSERT ls_nodes INTO TABLE lt_all_nodes.
        lv_counter = lv_counter + 1.
      ENDLOOP.
    ENDLOOP.
ENDLOOP.
IF lt_all_nodes IS NOT INITIAL.
    wd_this->rec_subobj( pt_nodes = lt_all_nodes    ).
ENDIF.
ENDMETHOD.
I should be able to give points to myself

How can I use one hierarchical table as a node of another hierarchical tabl

I have a requirement where I have two hierarchical tables and one table should work as node for other table . How to achieve this??
To elaborate more the structure is like
Main Table (Company Structure)
Sub table Consolidation Groups which has got hierarchical structure
Sub table Entity which is also hierarchical.
The Entity table should act as a node for table Consolidation Groups
How can I achieve this functionality??
Thanks
Suvarna

you misunderstood me apparently. I said you can't organinze to tables so one serves as a node's value of the other. Let me show you wnat I suggested by an example.
First table has such values:
-A
|-B
|-C
and the second one is
-x
|-y
|-z
-p
|-r
|-s
I thought you wanted to confine relationships between them so fo B node be able to select only x's branch and for C - only p's branch. If it's similar to the truth then let's create another table with two fields. Field one points to table containing capital letters and field two - lower case letters. Both fields are of type lookup pointing to an hierachial tables. Now when you populate this table you'll create records like (I list two columns):
B - y
B - z
C - r
C - s
from your orinal table from now you should point to the above table. So instead of having two fields each pointing to its own table and compeling you to think how to organize two hierarchies, now you have only one field pointing to a table with all valid combinations. When you populate this table though YOU have to decide what such combinations are. It may make sense (if you have different users) to restrict access to this table on read-only level for regular users to preserve the valid combinations.
Hope it helps but if I understood your wrong give a concrete example.

How to query 2 hierarchical tables and join?

Hi
I've been bashing my head against a well to get this to work efficiently in 10g. I can solve the following writing some pretty horrible SQL, but can't figure out how to do it elegantly and optimally.
We have two hierarchical tables as follows:
select * from data_categories dac
dac_code name parent_dac_code
10 MANAGEMENT
20 MEDICATION 10
30 PROCEDURE 10
40 SURVEY
50 ASSESS
60 NATURE 50
70 OBSERVE 60
select * from data_elements des
des_id name parent_des_id dac_code display_seq
100 DOSE MEDICATION 1
110 1MG 100 1
120 2MG 100 2
130 3MG 100 3
140 ROUTE MEDICATION 2
150 ET 140 1
160 EM 140 2
170 RESPONSE MEDICATION 3
180 IMPROVED 170 1
190 NOCHANGE 170 2
200 FILED MANAGEMENT 1
210 INPUT OBSERVE 1
You'll note:
1) We have hierarchies in both tables, and a fk from data_elements to data_categories via the dac_code.
2) The depth of both data_categories and data_elements is unlimited.
3) There is no single root node record in either table.
4) The appropriate PK and FK indexes exist.
We need to write a query that returns the following results:
root_dac_code parent_dac_code des_level des_id name display_seq
ASSESS OBSERVE 1 210 INPUT 1
MANAGEMENT MEDICATION 1 100 DOSE 1
MANAGEMENT MEDICATION 2 110 1MG 1
MANAGEMENT MEDICATION 2 120 2MG 2
MANAGEMENT MEDICATION 2 130 3MG 3
MANAGEMENT MEDICATION 1 140 ROUTE 1
MANAGEMENT MEDICATION 2 150 ET 1
MANAGEMENT MEDICATION 2 160 EM 2
MANAGEMENT MEDICATION 1 170 RESPONSE 3
MANAGEMENT MEDICATION 2 180 IMPROVED 1
MANAGEMENT MEDICATION 2 190 NOCHANGE 2
MANAGEMENT MANAGEMENT 1 200 FILED 1
You'll also note we need to return the data in order of the root_dac_code, then parent_dac_code, followed by the display_seq.
Does anybody know how to write this query in an elegant and optimal manner?
Many thanks for any help!
Cheers,
CM.

Flakey model.
Why does data_elements.dac_code appear to refer to data_categories.name rather than data_categories.dac_code?
You do not appear to be ordering by root_dac_code, parent_dac_code and display_seq (if you were MANAGEMENT/MANAGEMENT would not be at the end). Did you perhaps mean ORDER BY root_dac_code, des_id, display_seq?
Something like this perhaps?

Hierarchical Table Commands in MDM API

Hi,
I found only RetrieveLimitedHierTreeCommand,RetrieveLimitedHierChildrenCommand in MDM API for hierarchical tables.
So how can we add a child or a sibling, delete a child or sibling to the nodes of the tree.
Can anyone please give me links or some documentation on how to proceed with this.
The other problem we are facing when retrieving the children using RetrieveLimitedHierTreeCommand
When we add a search on the command it does not retrieve the children. it says the children for the level one node are null but if i donto set search it retrieves the children for all the nodes.
Is there any specific setting that has to be done for using the search.
Please let me know
Thanks,
Padmaja

Hi Greg,
I am adding the code snippet below. Can you please look into this and check if there are any problems
RetrieveLimitedHierTreeCommand hr=new RetrieveLimitedHierTreeCommand(conAccessor);
Search ser=new Search(repoSchemacmd.getRepositorySchema().getTable("New_Code").getId());
FieldId fldId =repoSchemacmd.getRepositorySchema().getTableSchema("New_Code").getField("New_Code").getId();
StringValue fldVal = new StringValue("G0440");
ser.addSearchItem(new FieldSearchDimension(fldId),new TextSearchConstraint(fldVal.getString(),TextSearchConstraint.EQUALS));
hr.setSearch(ser);
ResultDefinition rd=new ResultDefinition(repoSchemacmd.getRepositorySchema().getTable("New_Code").getId());
rd.setSelectFields(repoSchemacmd.getRepositorySchema().getTableSchema("New_Code").getFieldIds());
hr.setResultDefinition(rd);
hr.setSession(userSessionID);
try {
hr.execute();
} catch (CommandException e) {
e.printStackTrace();
When i execute this part of code and get the children. i get the children as null.
Thanks,
Padmaja

Navigate to needed row in hierarchical table

Hello everyone.
I have a problem related to Table UI Element. In my case it has hierarchical structure. By default, all nodes are collapsed. I need to provide user with ability to find nessesary element: if it's leaf, then all parents above have to be expanded and row is selected. I did this. Unfortunately, if found row has big index, it isn't displayed and I have to scroll down to find my selected row. I know that I can set "FIRST_VISIBLE_ROW" property of table. But how can I determine index? Internal table which is the source for hierarchical table has different number of rows. For example my internal table has 700 rows, when in the UI table only 120 rows are displayed.

Does anybody know?

Best way to create hierarchies tables

Good morning all,
I wanted to discuss the best practices of creating hierarchies to be consumed by OBIEE. As far as I understand, OBIEE has been optimized to use flattened hierarchies, such as:
ROW_WID CITY COUNTRY
1 NEW YORK CITY USA
2 MOSCOW RUSSIA
3 KIEV UKRAINE
4 SYDNEY AUSTRALIA
5 ATLANTA USA
Let's call it option 1. The only problem with this is that it has a potential to grow very wide. Also, There's a chance for confusion when there're duplicate entries, such as "New York" (city) and "New York State". Also, it's not always possible to define hierarchical relationships between data in a flat table - so-called ragged hierarchies. I found two major way of dealing with those (stack and flattening them out). Are there any other ways to deal with those? Specifically, I'm interested in dealing with hierarchies that involve complex positioning (a person might be a manager vertically, but managed horizontally - or - a person can have 2 managers - on different levels).
Also, in the example above - can I create dimensional outriggers (assign surrogate keys instead of text values to the dim - such as having NEW YORK as 100, MOSCOW as 200)? Sort of snowflaking a dimension. I was asked to do a proof of concept for this - but haven't been successful so far. If yes, could you please provide a simple Dim Outrigger < Dim < Fact diagram.
Thank you

Thanks Peter - I've checked that document before (I believe it's based on Kurt Wolffe's document on Siebel Analytics which I checked as well).
This option is fine if you're not going to do frequent changes - but in my case - it'll be a hell to maintain. We're sort of trying to prototype best solution - and it seems as flattening hierarchies is the best option, of course, given its limitations.
Also, there's another option of taking a different path and splitting and then building separate hierarchies

How to calculate level summary in Hierarchical tables by level

Hi ,
We all know how to present the data in hieararchical tables using CONNECT BY PRIOR and START WITH clause.
Did anybody get the sum on each level , rolling up this informations up to Top level.
Ex. Table Project_Task
(Task_id number,
Task_name varchar2(20),
Parent_task_id number,
Budget number).
Need to get report having sum(budget) on different level.
Level Task Name Total Budget

I don't have 8.1.7 to test with anymore, but as I recall, you can create a new table from a join of your original tables, then query the new table. I believe you could also create a temporary table and insert into it, then select from that. What I am not sure about is whether 8.1.7 will allow the hierarchical subquery in the select clause or not. Please test the following and let us know. If not, then you will probably have to use PL/SQL.

Do you really want attributes displayed that way?

Best way to pass back data from hierarchical table view?

Hi,
I have a view hierarchy using a navigation controller that's working pretty well. One of the bottom level views is a table view where the user selects an item from the list. This bottom view checks the list item, saves the selected item in a property, and then pops the view off the stack.
What's the best way to alert the parent view that the child view has been popped off so it can retrieve the value in the property? The calling push returns immediately, so it doesn't appear to be a modal call. I want to be able to use the same controller from other parent forms, so I need to be able to do this without referencing the parent in the child form ideally.
Thanks
Ray

Hi, well let me try to explain it a bit more
- Add a "delegate" property to your child-viewcontroller-class
- Define a protocoll within each chil-viewController-class
In this example let us name it "didSelectValue:(NSString *)value"
- In the parent-viewcontroller before pushing a child-viewcontroller set it's delegate property to "self" (parent-viewcontroller)
- In the parent-viewcontroller implement to protocoll-method "didSelectValue:(NSTring *)value"
- In the child view-controller in (assuming it is a tableViewcontroller) add some code in didSelectRowAtIndexPath that checks if the delegate is set and check if it responds to selector "didSelectValue:(NSString *)value". If so, call it with the selected value.

Managing Hierarchical tables

Hi all,
I need a query to get the emp hirarchical table as follows: (BASED ON EMP TABLE)
KING --> JONES --> SCOTT
KING --> JONES --> FORD
and so on...
In other words, all the path from the president to the last level of the organization in one line each. For example:
King is manager of Jones, and Jones is chief of Scott and Ford, so I want to display both paths.
Moreover, I don't want to filter anything, I want to show all the possible paths for all the employees.
I would appreciate your help.
Thanks.

In Oracle 8i, you can do the same thing, using the following packaged function by Solomon Yakobson:

                        vDelimiter      IN VARCHAR2 DEFAULT CHR(0))
                        RETURN VARCHAR2;
        PRAGMA RESTRICT_REFERENCES(Branch,WNDS);

Troubles when trying to transfer a table with hierarchical column to a tree

In WD for ABAP, I encounter many troubles when trying to transfer a table with hierarchical column to an actual tree. In my UI, the tree is in the left pane and the detail for a node is in the right.
1. With hierarchical table, I can bind the dataSource of the table directly to the context node in View which is mapped to a context node in component controller which is a DDIC structure. But with a tree, is it possible to map the dataSource of the tree or node in tree to context node in component controller?
2. With hierarchical table, when lead selection changed, the detail info in the right pane will change automatically. But with a tree, it seems to have to be implemented via action by myself.
Can anyone give some suggestions to overcome these troubles?

Wei,
<i>With tree table, the dataSource of the table is just bound to the context node ORG_UNIT</i>
Hmmm... You said, that this node resides in component controller, not in view controller. Or does it?
Any recursive node that can be displayed with tree table can be displayed with tree as well. Period.
1. Create tree and bind data source to the same node as table data source.
2. Create tree node type and bind it to the same node again.
3. Create one additional calculated attribute in forementioned node (type boolean) that inverts/negates attribute for table column "hasChildren" to tree node "isLeaf".
4. That's all.

Hierarchical Tree Table

Hello! There,
     I have to add a JTable in java application, It is so simple but I have problem when requirements has changed like Table/Grid should be in Hierarchical. Means Hierarchical Table like Table with Tree. I have a Hierarchical Tree Table sample but this is a XUL example. So, If you want to see, create a sample.xul file and put below code to that and open using mozilla browser.

Hi,
A well implemented JTreeTable can you found as a part from the SwingX-library.

Sql query to retrieve records in parent sibling relationship in a table

I need help to write this Sql query on a table where it has the primary_id, parent_id, and sibling_id. A new row can be created with or without the parent_id and sibling_id. However most of the new rows are created from an existing row and the primary_id
of the existing row is inserted to the parent_id of the new row. This can go on for many many rows such as (B's parent_id has A primary_id, A's sibling_id has B primary_id), (C's parent_id has B primary_id, B's sibling_id has C primary_id), (D's
parent_id has C primary_id, C's sibling_id has D primary_id), What I want is when user pass on a primary_id on a row, the query will give me back all the related parent_id or sibling_id records. For example User pass the A's primary_id the query will
give me back the Row B and Row C as a sibling rows or user pass the C's primary_id the query should give me back row B and Row A as parent rows. Thanks

Webdynpro :: Hierarchical ALV display

Hello All,
I am new to Webdynpro ABAP. I am having a problem in ALV Hierarchical List display.
As per my requirement, I need to display an ALV Hierarchical List with first column as Hierarchical column.
Hierarchical level shpuld be up to 6 levels.
I have made the table as Hierarchical table , set the column as hierarchy.
I am able to display only one node and one leaf.
Sample Code:
data : alv_config_table type ref to CL_SALV_WD_CONFIG_TABLE.
wd_this->alv_config_table->if_salv_wd_table_settings~set_display_type(
if_salv_wd_c_table_settings=>display_type_hierarchy ).
DATA : lr_column_hier TYPE REF TO cl_salv_wd_column.
lr_column_hier = wd_this->alv_config_table->if_salv_wd_column_settings~get_column( 'NODE_CONTENT' ).
lr_column_hier->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).
Anyone can suggest, how I can display multi level hierarchy for the same column.
Thanks in advance for yours inputs.
