Master Column Sequence in Table
Hello,
Is there any way to move Master Column like TableTree to the second place and let a normal column have the first seat?
Thanks
Alternatively:
SQL> select table_name,
trim (dbms_xmlgen.getxmltype ('select max(sal) m from ' || table_name).extract ('//text()')) max_sal
from user_tab_cols
where column_name = 'SAL'
TABLE_NAME MAX_SAL

How to populate the master column in a table
Hi Experts,
I am trying to implement a hierarchy structure in a table. For that I have inserted a master column of TreeByNestingTableColumn type. The value which are getting displayed in a table are hard coded by me, but I am not able to understand how should I populate the values so that when the table initially appears, it should contain some data (which I hard code) and when I click the master column, it should expand and display value according the master column selected(which I again hard code).
Please help me in achieving it.
Regards
ArjunHi,
Go throgh the tutorial "Creating a Tree Structure in a Table" in the blow link.
Web Dynpro Java Tutorials and Samples NW 2004 [original link is broken]
In these example only the souce of data changes as per your requriement. In the examples they are reading data from java class.
1. First you need to create a value node with (Parent Id, Boolean Type: isLeaf, Expanded, ChildernLoaded), attributes.
2. Then you have to create one recursive node under that Value node by selecting that node as reference.
3. As given in the example create one method called addChildern(Node, ParentId).
4. Now in the wdDoInit method call this method by passing the Value node and "ROOT" as parent Ids
5. In addChildern method if parentId is ''ROOT" then populate all the root elements in the parent node.
6. Now root elements will be populated.
7. When user clicks on any of the root element then invoke the action loadChildern(this should be binded to Master column) and pass recursive node of that parent element and the parenId (as given in the exmaple).
8. Based on this parentId now populate the chids in addChildern method.

Insert master column on table not found in NW CE EHP1
I installed SAP Netweaver CE EHP1 sneak preview. I inserted the table UI element. I am trying to insert a master column in the table. But I was not able to find the option to insert master column from the context menu of the table in NW CE EHP1 sneak preview. I was able to do it with previous versions. I am not sure whether it is a bug on this version. Any help is appreciated.
ThanksGo to Context Menu of the table and select to insert Row arrangement then you see tree by nesting table column.

Table with tree view on master column
Hi,
I'm trying to generate a table with tree view on the master column and I get the table values from an RFC.
The problem is that I need to control some properties like "expanded" or "isLeaf" and I can't add the value attributes to the model node to control the rows.
Any ideia on how to overcome this (what i think is a) problem?
Thanks for the help.
Pedro BarbosaHi Subramanian,
Maybe I didn't explain myself right. I also followed that tutorial with success but in this case i have on my custom controller:
-MyNode (model node)
- Output
- MyTable
- attribute 1 (model attribute)
In my context/view controller the only way i can map that node is by using a model node referecing "MyTable" but this way i can't add any of my attributes to same level of the attributes (is that the ideia right?).
I also tried to recreate the structure in the view with value nodes and value attributes with the same type as the model attributes and then bind them but i always get "Incompatible context element type".
Am i missing something?

How to use Radiobutton Cell Editor in Table using Master Column
Hi Guys,
I have a Table that uses a Master Column. I need to have a field that uses a Radio Button type cell editor. A user should only be ably to select ONE row via the Radio Button at a time.
I have done all this but I only seem to be able to select multiple radio buttons instead of only one. It is like the radio buttons do not get "regognised" as a group. Could you please advise as I probably set the "keyToSelect" and "selectedKey" properties incorrectly.
tks
ChristiaanI think the following should work:
Context:
Rows (node,c=0:n)
--- rowIndex (integer)
selectedRowIndex (integer)
Bind the "selectedKey" property of the radio button (cell editor) to attribute "selectedRowIndex" (outside table data source node) and bind "keyToSelect" to attribute "Rows.rowIndex". Make sure that the "rowIndex" attribute will contain the index of the node element in node "Rows".

Hello WD-Experts,
I have bind a table into WD dynpro using table UI-Element. The data will shown perfectly.
My issue: I like to change the sequence of the different columns.
Example:
col1 col2 col3
col3 col1 col2
Changing the columns by track and drop is just visible in the ROOTUIELEMENTCONTAINER, but not in the layout itself.
Has anybody an idea how i can change the column sequence?
Thank you very much in advance.
regards
AxelHi Axel,
We can change the sequence of table column. For this Chose the Edit Mode for your view. Navigate to your Table UI element. Click on it so it shows you all the Columns. Now select a column u wish to move and just right click on that . u will see a option called up and down . With this u ws will move ur column in upper and downward direction. So by this u can change the sequence of any column in ur table.

Multiselection in Tables with Master Column
The use case is the following:
I have a table with a master column in which I display a tree. The table is bound to a dataSource with a recursive node.
I'd like to implement multiple selection for the rows of this table, but it doesn't work (even when making context node's selection 0..n).
Is there any work-around for solving this problem?Thanks for the suggestion.
But there is still problem with this:
I will have have two methods for selection of rows of the table - there will be standart one which is provided by webdynpro and additionaly I will have a column of checkboxes. It is not convinient form user-perspective. Furthermore I can't put columns on the left of the master column which is also a problem, the checkboxes should be situated in the firs column.

WDA Table: Getting column sequence as it really is for the user
Hi Folks!
I need the current sequence of table columns as it really is for the user. He may have personalized his table: he may have removed some columns and may have changed the sequence of some columns. And this is what I need to know.
But unfortunately so far I could only get the column sequence as it is defined in the View Layout using this coding:
DATA lo_table TYPE REF TO cl_wd_table.
DATA lo_table_columns TYPE cl_wd_table_column=>tt_table_column.
DATA lo_table_column TYPE REF TO cl_wd_table_column.
DATA lt_abstr_table_columns TYPE STANDARD TABLE OF REF TO cl_wd_abstr_table_column.
DATA ls_abstr_table_column TYPE REF TO cl_wd_abstr_table_column.
lo_table ?= wd_this->mv_view->get_element( 'RLTAB' ).
lt_abstr_table_columns = lo_table->get_grouped_columns( ).
LOOP AT lt_abstr_table_columns INTO ls_abstr_table_column.
lo_table_column ?= ls_abstr_table_column.
ENDLOOP.
Thus: How to get the table column information as they are currently outside in the reald user world (only visible columns in the displayed sequence).
Background: I need this information, because I want to export the table to excel and/or print it in exactly the state the user currently sees it (in personalized state).
Thanx and points for any useful hints - ideally coding snippets!
Regards,
VolkerHi both!
1) I have searched the framework like a mad man an dI think I will dream of all these IF_WD... and CL_WD... most having the useful information in protected or even private areas. A fact I cannot really understand.
2) Although some kind of "criminal" I trewd to go the way in the second answer by creating child classes for cl_wd_abstr_table_column and cl_wd_table_column both containing the protected attribute PERSINDEX I need.
I added a public class get_pers_index to the child classes. So far so good.
But when I try to type-cast SAP standard instance to my instance vairables I get type-cast errors in both cases.
Any ideas?
Here's the relevant coding snippet:
DATA lo_table TYPE REF TO cl_wd_table.
DATA lo_table_columns TYPE cl_wd_table_column=>tt_table_column.
DATA lo_table_column TYPE REF TO cl_wd_table_column.
DATA lo_table_column2 TYPE REF TO /rand/cl_wd_table_column.
DATA lt_abstr_table_columns TYPE STANDARD TABLE OF REF TO cl_wd_abstr_table_column.
DATA ls_abstr_table_column TYPE REF TO cl_wd_abstr_table_column.
data lo_abstr_table_column type ref to /rand/cl_wd_abstr_table_column.
data lv_pers_index type i.
lo_table ?= wd_this->mv_view->get_element( 'RLTAB' ).
lt_abstr_table_columns = lo_table->get_grouped_columns( ).
LOOP AT lt_abstr_table_columns INTO ls_abstr_table_column.
lo_table_column ?= ls_abstr_table_column. "this casting is successful
lo_table_column2 ?= lo_table_column. "this casting throws type-cast exception
lv_pers_index = lo_table_column2->get_pers_index( ).
lo_abstr_table_column ?= ls_abstr_table_column. "this casting throws type-cast exception, too
lv_pers_index = lo_abstr_table_column->get_pers_index( ).
ENDLOOP.
Any help very welcome.

Selection in table with Master Column
Hi,
can anybody explain me how selection works in table with MasterColumn (TreeByNestingTableColumn)?
I've created a table with several columns and the "master" one behaves differently from others.
First of all, leaf elements of master column are not clickable (i.e. I don't receive notification "onLeadSelect" from the table, when user clicks in the cell of leaf element of the column). With expandable elements I receive loadchildren event and can react on selection.
I'm using TextView as cell editor, will try LinkToAction, may be it will resolve situation, but it's rather workaround as solution
Second, getLeadSelection doesn't work anymore for the table - it works with indexes of top level elements only.
However onLeadSelect action brings me selected row number, which I somehow should map to the tree.
I.e. when I get "25" as selected element, I recursively traverse context node to find 25th element. Which is rather slow operation as for any selection I have to reiterate whole structure and I hope that visual appearance is similar to context element order.
May be there is simplier ways to get selected element by its index in "flat" list?
And one another strange thing: first click on the table sends me onLeadSelect "0", but highlight points to the element user clicked - not necessary first one.
Context node is "single" selection, initLeadSelect=true,
selection = 0..1 (with 1..1 setTreeSelection doesn't work - method I want to use to be able to select a node in hierarchy on my own)
all quite similar to other tables I have, which works well. Just the problems with the table, where Master Column is used.
Thank you!
Best regards,
Nick>Valery's proposal was to perform reverse traverse from current element to root and summarize parent element indexes.
It seems to work:
in method, which sets selection I applied
// we need to know index of the element not in whole context, but in scope of table-relevant node
int index = getIndexInContext(selElement, wdContext.currentXXXElement());
IContextElement curContext = wdContext.currentContextElement();
int firstVisibleRow = curContext.getTableFirstVisibleRow();
int visibleRows = curContext.getTableVisibleRows();
if (index < firstVisibleRow || index > firstVisibleRow + visibleRows) {
curContext.setTableFirstVisibleRow(index);
and method getIndexInContext looks as:
private int getIndexInContext (IWDNodeElement element, IWDNodeElement root) {
int index = element.index();
if (element == root) {
return index;
IWDNodeElement parent = element.node().getParentElement();
if (parent == null) {
// do whatever you like here for error diagnostic
myMsgMgr.reportException("Internal Error: getIndexInContext - element is not under passed root", false);
return 0;
// +1 - every level adds 1 (otherwise indexes of first children of hierarchy will be 0)
return index + getIndexInContext(parent, root) + 1;
Best regards,

Unable to see a column of a table in portal for a particular User
Hi,
A particular user is unable to see a particular column of a table in the portal . The application is developed in Webdynpro ABAP. The table contains two columns. Both the columns contain text type fields. What appears to the user is that the left column has disappeared and the right hand column has shifted to the left.
This is occuring for a particular user only. We have checked in our development and quality systems but we are unable to replicate the issue. Please help.
Thanks and regards,
Satya.Hi Vikas.
You can use BAPI in LSMW to craete Material or You can use direct input method. Both methods as follows below:
Using BAPI in LSMW:
First maintain IDOC Inbound Processing steps by giving PORT and Partner Type and Partner Numberby clicking 'settings' icon in menu path in LSMW Screen.
Adn then execute LSMW and maintain the values as below in the first step.
BusinessObject Method(BAPI)
Business Object BUS1001006 Standard material
Method SAVEDATA Create and change materia
Message Type MATMAS_BAPI Create and change materia
Basic Type MATMAS_BAPI03 Create and Change Materia.
For the selecting of views, you can maintain fields for all views(From Basic view to costing view) in your excel and populate with 'X' in respective fields for activating views.
In the 6th step (Maintain field mapping and conversion rules). you can map those fields for views which you want to activate since we have all views are in the standard structure.
Using Direct Input Method:
Standard Batch/Direct Input
Object 0020 Material master
Method 0000
Program Name RMDATIND
Program Type D Direct Input
For the selecting of views, you can maintain fields for all views(From Basic view to costing view) in your excel and populate with 'X' in respective fields for activating views.

How can we change the column sequence from 1st to 7th position
Hi
I have a table in which I have a column naming DNAME and it is is on the first position I want to change its position to 7 that is the last one. The table is huge filled with data.
Is there ant way in which I can cange the position of the column with out recreating in into another table and then renaming it.
ThanksHello,
The sequence of a column in a table is meaningless and you should treat it as such. The column ordering you see when you run a "select * from ..." query is based on the physical implementation of the table, which is completely separate from the logical interpretation, and should not be relied on in a programmatic context. It should essentially be viewed as "random" and prone to change with the physical storage properties of the table (although this is not always the case, there is no assurance of this).
One way to do this (which happens to be the easiest and least resource-intensive in this case) is to create a view (derived relation) of the base table, with the columns ordered in the specific sequence you desire. But really, the column ordering here is still meaningless, and the only time your application should rely on the order is when you specifically list the columns you require in a query -- but NEVER a "select *".
cheers,

Cannot find Master Column in Outline view
Hi Guys,
We are using NWDS 7.1 Composition Environment SP05 for development.
I am trying to do a Tree control nested in a Table. I am at the point where I'm supposed to add the Master Column from the context menu in the Outline perspective - but it is not there! I mean there is no entry called "Add Master Column" or somehting like that.
What am I missing?
Thank you.
ChristiaanHi,
Following is the way to add a master column in CE
Right click on the table.
Select Insert-> Row Arrangement->Tree ByNesting Table column.

How to encrypt column of some table with the single method ?
How to encrypt column of some table with the single
method ?How to encrypt column of some table with the single
method ?
using dbms_crypto package
Assumption: TE is a user in oracle 10g
we have a table need encrypt a column, this column SYSDBA can not look at, it's credit card number.
tha table is
SQL> desc TE.temp_sales
Name Null? Type
CUST_CREDIT_ID NOT NULL NUMBER
CARD_TYPE VARCHAR2(10)
CARD_NUMBER NUMBER
EXPIRY_DATE DATE
CUST_ID NUMBER
1. grant execute on dbms_crypto to te;
2. Create a table with a encrypted columns
SQL> CREATE TABLE te.customer_credit_info(
2 cust_credit_id number
