Ho to get the structure for a subnode

Hi Experts,
I am an beginner in webdynpro abap - sorry for this simple question, but I have not found an answer.
I have a context node generated from a interactive form. Let's call this node 'node1'.
Within this node I have a subnode 'subnode1' containing the elements for an internal table.
My simple question is: Ho can I get the structure of the subnote element?
I mean, this is clear for me:
DATA:
ls_node1 TYPE wd_this->element_node1.
But how about:
ls_subnode1 type ?????????????????
I guess the answer is quite simple... Thanks for your help.
Andreas

Hi,
This will be of the same type that you declared while creating the context node element node1. You may go to the context node tab to see the dictionary structure. Alternatively you double click on wd_this which would display the inferface for wd_this and search for element_node1 there.
Let me know if this helps.
Regards
Prasenjit

Dynamically get the Max value from table and insert max value + 1 in Target

Hi All, I have a requirement given below, need help in building a solution for this: A mapping that will get the dynamically get the max value(Basically a number) from table , this target table is used by many other concurrent jobs and updated very frequently. My requirement is to get max value from this target table dynamically (Using dynamic look up) and then have an expression to increment by 1 and then load it to Target.I tried using SELCT max(col1) from target in dynamic look up override but this does not seem to work.Any work around here? I dont insist on using a SQL transformation here as Production DB could have 3 Million + records! Thanks in advance, -KRB

How to dynamically get the SOM expression of a field?

As a follow up to the note below, I would really appreciate any help as of how to get the SOM expression of a field dynamically, by this, I mean how to get the SOM expression of a field at running time using JavaScript.
Thanks,
Isis
That does make things clearer. You will have to save the change information in the XML. I realize that you don't want to save an xml node for every field, but there is a better way. You can use scripting to add data nodes to the XML data in the form. I'm thinking of the following:
Include an empty container node in your XML schema: <HighlightedFields></HighlightedFields>
When a field is changed, in the field's change event call a common script: HighlightChangedField, passing in the object. The script will highlight the field (set the border a certain color or whatever). It will also add node underneath the HighlightedFields data node with the SOM expression of the field. The SOM expression is the "path" of the object in the form heirarchy, sort of like an xpath. So if you have a subform named Subform1 and you change the Name and Address textfields, you might end up with something like:
<HighlightedFields>
    <HighlightedField>
        <SOMExpression>xfa[0].form[0].myform[0].Subform1[0].Name[0]</SOMExpre ssion>
     </HighlightedField>
    <HighlightedField>
        <SOMExpression>xfa[0].form[0].myform[0].Subform1[0].Address[0]</SOMEx pression>
     </HighlightedField>
</HighlighedFields>
The upside of this is that you only store XML nodes for what is changed instead of needing a specific XML node for each field. The downside is that you will need a call to the common script in every field's change event: HighlightChangedField(this);
Now, to make this work when a form is loaded the next time, in the initialize event at the topmost subform in the hierarchy you add a script that walks the HighlightedFields data node, and for each HighlighedField entry you highlight the contained object. You can get a reference to an object using its SOM expression, so just take the SOM expression from each entry and do an xfa.resolveNode(SOMExpression) to get the object, then set whatever attributes you want to highlight the field.
The big issue I see with this would be if you have dynamically added objects on your form. In that case you would probably need to store the instance index along with the SOM expression for each changed object, then use that instance number when highlighting on form load.

As a follow-up, I had said I would try to put together an example for you. The setting of the change indications and the highlighting of the fields is not a problem, but I did have an issue that perhaps one of the experts on the forum can help with:
The problem is how to detect a change in a text field without a lot of overhead. You can't just place a call to the highlight method in the Exit event without checking for a change, since the user can just tab from field to field without changing anything. Unfortunately the properties that show the old text and new text of a field are not valid on the Exit event. An alternative is to use the Change event, but with a text field the event fires for every character typed. This seems like a lot of extra processing..
Anyone know a better way? I went as far as using the extras collection on fields to hold the last value, but that adds a lot of complexity since it needs to be set to the initial raw value when the form is first loaded. I'd like to find a solution that doesn't require a lot of code to be added to every field on the form.

Dynamic passing of the structure in LVC_FIELDCATALOG_MERGE

Hi ABAP Gurus,
I'am doing report to read cluster results
My requirement is :
The report uses LDB -PNP in the selection screen in addition to that Clusterid is passed and what ever cluster id we select for the pernr that cluSter id results has to show in the report output
The report has to dynamically change in the output (whole structure of the cluster id) how to pass in selected cluster id (what we selected in the selection screen) in the function module
LVC_FIELDCATALOG_MERGE
Importing
I_STRUCTURE_NAME - (HERE I WANT TO GET THE STRUCTURE OF THE SELECTED CLUSTER ID IN THE SELECTION SCREEN)
Thanks and Regards,
Deepthi.

Recently I have been working on generic cluster access and I must say the task was challenging. What I've discovered is:
- generic access as per cluster ID is impossible via [IMPORT ... FROM DATABASE...|http://help.sap.com/abapdocu_70/en/ABAPIMPORT_SHORTREF.htm] -> in order to create a fully flexible access you would have to go for pure dynamic program generation by means of [GENERATE SUBROUTINE POOL|http://help.sap.com/abapdocu_70/en/ABAPGENERATE_SHORTREF.htm]
- as there are houndreds of available cluster IDs it is very difficult to determine those relevant to particular employee. For just one table PCL2 there are multiple of unknown to me areas which are hard to distinguish from those (un)relevant to employee. First look at fixed values from domain RELID_PCL2 gives the feeling what we are struggling with.
- focusing on all common clusters (only from PCL2) like CU, RX, ZL, B2, PS, PT can narrow the search result but still is a lot to be handled by one program
- eventually looking deeper only on RX and possibly B2 areas seemed to be the best choice (as mostly we use only those - at least I do). So I focused on this area as generic payroll result can be easily extracted. What I needed was extracting relid for given EE molga, then py result type for this relid, the simply using FM PYXX_READ_PAYROLL_RESULT to access py results itself for given cluster directory entry (table hrpy_rgdir )
- the final challenge was how to show the results in user friendly form. As the result table I had was not only nested but deep too it wasn't so obvious. Luckily to me I was using Web Dynpro which allows to create table popins (showing the table within the table) but I don't think there is corresponding GUI control in SAP GUI. So considering how you want to show this data is really not an easy thing to do.
- As for the structure of payroll result itself (or rather structure of each of its components) can be delivered using RTTI but you will also sweat a bit before getting that done.
To conclude. There is no easy way of accessing clusters by just giving its RELID Even though you would focus on some specific part, it will take you more time then you expect at the beggining. So I would try to suppress the tempation for a moment and consider all these discussed (and those which I didn't think of) aspects.

Little tip to get the nr of elements in a local structure using RTTI

sometimes you need to know the number of elements in a structure for manpulating data
for example you might need to convert the elements in an internal table to a special file format such as "field","field",......"field".
instead of something like this where you have counted the number of elements in your structure
you can obtain the number of elements dynamically. This saves changing the code each time you change the structure and can avoid errors.
data: zstring type string
data: zstring1 type string.
lv_index = 1.
    WHILE lv_index LE 47.
      .CLEAR zstring.
      ASSIGN COMPONENT lv_index OF STRUCTURE your_ structure TO <fsa>.
      CONCATENATE '"' <fsa> '"' INTO zstring.
      CONCATENATE zstring1 zstring INTO zstring1.
      CONCATENATE zstring1 ',' INTO zstring1.
      lv_index = lv_index + 1.
      CLEAR zstring.
    endwhile
lv_index = 48.
    ASSIGN COMPONENT lv_index OF STRUCTURE wa_interface_contracts TO <fsa>.
    CONCATENATE '"' <fsa> '"' INTO zstring.
    CONCATENATE zstring1 zstring INTO zstring1.
    CONDENSE zstring1.    "Left align all data fields within the string
    APPEND zstring1 TO ta_string1.
    CLEAR zstring.
    CLEAR zstring1.
    lv_index = 1.
Using the RTTI
DATA lr_rtti_struc TYPE REF TO cl_abap_structdescr .
DATA: zog    LIKE LINE OF lr_rtti_struc->components .
DATA: zogt                    LIKE TABLE OF zog,
CREATE DATA dref TYPE your_structure
ASSIGN dref->* TO <fs>.
lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <fs> ).
* get the structure details into a table.
* table zogt[] contains the structure details
zogt[] = lr_rtti_struc->components.
now the nr of rows in this table contains the number of elements in your structure.

FM to get the date specific structural help

I am working on structural help for Org id for a selection screen parameter.
I am using FM RH_OBJID_REQUEST. It is giving the structure valid ion today. My requirement is to get the structure valid on given period in the above selection field.
Please let me know is there any other way(other FM) to get the date specific structural help.

Pass your dates to ORGBEG     & ORGEND
Description
This parameter only applies to the search function.
The parameters ORGEND and ORGBEG together determine the period in which
     the organizational assignment data for positions is read. The entry in
     ORGBEG specifies the start of the search period.
Value range
Allowed values are all dates smaller than the date in ORGEND.
Default
The default value is the smallest system date.

Get the type of collecion elements

Hi,
I would like to get the type of the elements of a collection when I give the name the collection. Does anybody suggest anything about the SQL code?
For example
CREATE OR REPLACE TYPE CourseList AS TABLE OF VARCHAR2(64);
CREATE TABLE department (
name VARCHAR2(20),
director VARCHAR2(20),
office VARCHAR2(20),
courses CourseList)
NESTED TABLE courses STORE AS courses_tab;
How it is possible to get the type of elements of CourseList (in the example it is VARCHAR2(64)) if I give the name of the nested table courses?
Thank you

Smells like some kind of dynamic SQL or dynamic PL/SQL thing. It usually stinks.
If the dynamic part comes into play at rendering time (like in APEX for example that executes a SQL and then needs to dynamically render the projection) - use DBMS_SQL cursors (or ref cursors when rendering in an external client). Use the describe interface to dynamically determine the structure of the SQL projection.
Anything more than that - think carefully. Especially at it seems you want to deal with actual relational data structure dynamically. 99% of the time it is flawed and the remaining 1% of the time the person usually have no idea what he (or she) is really doing... ;-)

Check box als column in a standard table, how to get the selected row

Dear experts,
I habe standard tablt with check box as column. Now I want to get the current selected row structure and do some changes. How could I solve this problem? till now I just know to get the structure via lead selection.
lo_node->get_element().
lo_element = lo_node->get_static_attributes ( static_attributes = ls_row).
How could I get the element through check-box in stead of lead selection. Many thanks!

check this code
To get the selected row number
data: lr_element type ref to if_wd_context_element,
lv_index type i.
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
lv_index = lr_element->get_index( ).
Thanks

What is the code to get the Label of radio button item at runtime?

Hi All
I am working on forms 10g(version 10.1.2.0.2 ) with Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 on windows 2000 platform.
My requirement is to dynamically get the label of the radio button item in a radio group.I am able to get the label of the radio group as shown below
Item :Radio group
Label : Gender
IF m_type = 'RADIO GROUP' THEN
m_label:=Get_Item_Property(m_Item ,label);
END IF;
There two Radio buttons inside this radio group which are
item : Radio button
Label : Male
item :Radio button
Label :female
What is the code to get the label of radio button(i.e) male and female ?
How will I get the count of radio buttons in a radio group at runtime?

But you have to provide the button name which cannot be get at runtime.
This is a lack of information that the Dev team would correct !

Hi stephan,
1. In oracle , there is one standard view
eg. V_ALL_TAB_FIELDS
in which we pass the table name,
and it returns, the records,
for the fieldnames, field type, its length, its sequence number etc.
2. Similarly u may discover for PS also.
