Can anyone give me an example of a custom TableColumn

I just can't get to grips with creating a custom TableColumn
can somone give me a hand or a pointer to a tutorial, I just cant find one anywhere
Thanks

From that thread's description, I think everything you are asking to do can be controlled by the TableModel itself. The data, types, etc. (that are the data that drive the table) are all defined in your table model.
Just subclass AbstractTableModel and implement the necessary methods. If while running, you change the # of columns, data types, etc. just fire the appropriate event from your TableModel fireTableStructureChanged(), etc. The columns, etc. will be rebuilt using the updated information from your table model. Not sure given your description if you will need to do any of that though. I think you can just extend the abstract table and with your own logic in getValueAt() to return the appropriate value from your data.
Note that the table expects all of the data in a column to be the same type. If your underlying data may have values in different types (classes) you will need to convert them to something generic before returning them from your model (like as a String).
Read up on this tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
You pretty much don't have to muck with the TableColumnModel stuff unless you want to do advanced/tricky things like provide a generic way to hide/show columns, etc.

Hi all, I have a survey, there are several questions. After I input the answers, I click the 'CHECK' button, I will check the answers. There will be different response to my answers. If the answer is not correct, I will post an error message.
And I also need to retrieve data from tables to fill the blank.
I am a beginner for CRM survey, can anyone help me? I create a FM:crm_svy_..._pai, and code in it right? But how can I do it?
Can anyone give me an example for crm_svy_..._pai to do what I need?
Many many thanks in advance!!
Heare is an example, but I don't its function and how does it work..
read table lt_all_values into ls_value
                           with key answer_id = 'get_value'.
if sy-subrc = 0.
    data: lt_values type crm_svy_api_string_t.
    append ls_value-value to lt_values.
    call method ir_survey_values->values_set
      exporting
        i_question_id = 'set_value'

Can anyone give me an example of direct, queued and unserialized delta?

hi all,
Can anyone give me an example of direct, queued and unserialized delta for fi and sd applications.
thanxs in advance
regds

hi,
Update Methods,
a.1: (Serialized) V3 Update
b. Direct Delta
c. Queued Delta
d. Un-serialized V3 Update
Note: Before PI Release 2002.1 the only update method available was V3 Update. As of PI 2002.1 three new update methods are available because the V3 update could lead to inconsistencies under certain circumstances. As of PI 2003.1 the old V3 update will not be supported anymore.
a. Update methods: (serialized) V3
Transaction data is collected in the R/3 update tables
Data in the update tables is transferred through a periodic update process to BW Delta queue
Delta loads from BW retrieve the data from this BW Delta queue
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Issues:
Even though it says serialized , Correct sequence of extraction data cannot be guaranteed
V2 Update errors can lead to V3 updates never to be processed
Update methods: direct delta
Each document posting is directly transferred into the BW delta queue
Each document posting with delta extraction leads to exactly one LUW in the respective BW delta queues
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Less monitoring overhead of update data or extraction queue
Cons:
Not suitable for environments with high number of document changes
Setup and delta initialization have to be executed successfully before document postings are resumed
V1 is more heavily burdened
Update methods: queued delta
Extraction data is collected for the affected application in an extraction queue
Collective run as usual for transferring data into the BW delta queue
Transaction postings lead to:
1. Records in transaction tables and in extraction queue
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Suitable for environments with high number of document changes
Writing to extraction queue is within V1-update: this ensures correct serialization
Downtime is reduced to running the setup
Cons:
V1 is more heavily burdened compared to V3
Administrative overhead of extraction queue
Update methods: Un-serialized V3
Extraction data for written as before into the update tables with a V3 update module
V3 collective run transfers the data to BW Delta queue
In contrast to serialized V3, the data in the updating collective run is without regard to sequence from the update tables
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3.This BW Delta queue is read when a delta load is executed.
Issues:
Only suitable for data target design for which correct sequence of changes is not important e.g. Material Movements
V2 update has to be successful
hope it helps

Can anyone give me an example of for all entries in case of inner join

Hi abapers,
I am trying to replace an inner join with for all entries.
So kindly give me a demo code so that i can understand the use and apply it.
And plz tell me in which case it is better to use for all entries and in which case to use inner join so that better performance will occur.
With Regards
Ansuman

Hello Ansuman,
For example:
DATA:
BEGIN OF fs_eket,
    ebeln LIKE ekko-ebeln,             " Purchasing Document Number
    ebelp LIKE ekpo-ebelp,             " Item Number of Purchasing Doc
END OF fs_eket.                      " fs_eket
DATA:
t_eket LIKE                          " Purchase table
STANDARD TABLE
      OF fs_eket.
Using joins:
select ebeln ebelp
into corresponding fields of table t_eket
from ekko join ekpo
on ekkoebeln eq ekpoebeln
where ebeln in s_sbeln.
The select statement can be replaced by
SELECT ebeln
FROM ekko
INTO CORRESPONDING FIELDS OF TABLE t_eket
WHERE ebeln IN s_ebeln.
IF sy-subrc EQ 0.
sort t_eket by ebeln.
SELECT ebeln
         ebelp
    FROM ekpo
    INTO CORRESPONDING FIELDS OF TABLE t_eket
     FOR ALL ENTRIES IN t_eket
   WHERE ebeln EQ t_eket-ebeln.
The duplicate entries are removed by using FOR ALL ENTRIES. Or else by using the join, you have teh sort the table by key fields and then delete adjacent duplicates.
Hope it helps you

Indu

Can anyone give me examples of replacement path with query?

hi all,
Can anyone give me examples of replacment path with query. if u have any docs pls send it across to my email id [email protected]
thanxs
hari

Here is an example:
Lets assume you have a characteristic( Say Project) with about 30 attributes. now your requirement is to display all 30 attributes and about 10 keyfigures and another characteristic and it's attributes...
If Project has about 25K projects in a Year,you will find its very difficult to diasply all the inofmation with one Query.(you may get disconnected from server after executing the query)..
So firstly,create a Query1 only with Project and keyfigures.
then create another Query2 only with Project and its attributes...here create a variable on Projeect with replacementpath and select the Query1.So you will have the Projects only from Query1.
Create Query3 with Project and other chars.create one more variable on Project with replacementpath select Query1 result. So this Query also gets Projects from Query1...
Now Query2 and Query3 get Projects from Query1 always...so you will have same Projects in your all 3 Queries..
Now crate a workbook and insert 3 Queries.make sure you insert Query1 lastly.Since last inserted query will be executed first...
You may use VBA or excel functionality if you want to see whole data in one sheet.
Hope this helps.

Can anyone give me a simple workflow example?

So I need to make a banner (468 x 60) with flash that
basically is just a background, some text, that text disappears and
new text shows up, and then some falling hearts. I've been through
so many tutorials, but I STILL get confused as to the exact
workflow when doing this. I understand about making movie clips,
but do I make a movie clip of a line of text, then what do I do?
How do I make it disappear and a new line of text show up? Should I
do this all on Scene 1 or do I need to somehow animate within the
movie clips? Also, I have a heart that falls and rotates at the
same time - I don't want it to do a full rotation, so I tried
rotating the instance of it in the beginning and have it motion
tween to do a 1/4 rotation, but when I try to animate it, it just
shows it falling and then rotating at the very last frame. Say I
want to show "screen A" of text, then show "screen B" then finally
"Screen C" which includes some hearts animating, can anyone give me
a real basic outline of what to do? I mean, the order I should do
stuff, what needs to be made into a movie clip, what each movie
clip timeline should look like, and what the Scene 1 timeline
should look like. OR if anyone knows of a decent tutorial that
basically shows how to do something like this. Thanks!!! (*puppydog
eyes*)
p.s. i just want the text to fade-in/fade-out unless that is
complicated enough that a flashtard like myself couldn't do it
easily.

wouldn't it make more sense that a flashtard is someone who
just generally sucks at flash and asks idiotic questions?
anyway, so i pretty much got the banner done - but i'm stuck
on one problem. I made a motion clip of a heart, and i want the
heart to fall from top to bottom, following a squiggly motion
guide, and to rotate 1/4 turn on the way. I got it as far as
following the motion guide, but when i try to select the instance
in the first frame and rotate it, shouldn't the motion tween make
it appear to slowly rotate, rather than stay put then rotate 1/4
turn at the last frame? When I select the clip and play around with
alpha and stuff, that works fine. What the heck?

Can anyone give me some documents for data cluster

Hi,
can anyone give me some documents for data cluster?
ths!
regards!

Hi ,
The following is a documentation on the Data Cluster:
Data clusters are specific to ABAP. Although it is possible to read a cluster database using SQL statements, only ABAP can interpret the structure of the data cluster.
You can store data clusters in special databases in the ABAP Dictionary. These are called ABAP cluster databases, and have a prescribed structure:
Cluster Databases ( I have explained the cluster databse below )
This method allows you to store complex data objects with deep structures in a single step, without having to adjust them to conform to the flat structure of a relational database. Your data objects are then available systemwide to every user. To read these objects from the database successfully, you must know their data types.
You can use cluster databases to store the results of analyses of data from the relational database. For example, if you want to create a list of your customers with the highest revenue, or an address list from the personnel data of all of your branches, you can write ABAP programs to generate the list and store it as a data cluster. To update the data cluster, you can schedule the program to run periodically as a background job. You can then write other programs that read from the data cluster and work with the results. This method can considerable reduce the response time of your system, since it means that you do not have to access the distributed data in the relational database tables each time you want to look at your list.
Cluster Database :
 Cluster databases are special relational databases in the ABAP Dictionary that you can use to store data clusters. Their line structure is divided into a standard section, containing several fields, and one large field for the data cluster.
Creating a Directory of a Data Cluster
To create a directory of a data cluster from an ABAP cluster database, use the following statement:
Syntax
IMPORT DIRECTORY INTO <dirtab>
 FROM DATABASE <dbtab>(<ar>)
 [CLIENT <cli>] ID <key>.
This creates a directory of the data objects belonging to a data cluster in the database <dbtab> in the internal table <dirtab>. You must declare <dbtab> using a TABLES statement.
To save a data cluster in a database, use the EXPORT TO DATABASE statement .
For <ar>, enter the two-character area ID for the cluster in the database. The name <key> identifies the data in the database. Its maximum length depends on the length of the name field in <dbtab>. The CLIENT <cli> option allows you to disable the automatic client handling of a client-specific cluster database, and specify the client yourself. The addition must always come directly after the name of the database.
The IMPORT statement also reads the contents of the user fields from the database table.
If the system is able to create a directory, SY-SUBRC is set to 0, otherwise to 4.
The internal table <dirtab> must have the ABAP Dictionary structure CDIR.
******** Sample Program illustrating the data cluster .
PROGRAM Zdata_cluster.

Can anyone give a good contact number for someone in the upper level of customer service

can anyone give a good contact number for someone in the upper level of customer care i have talked to two of the worst people from customer service, the "supervisor" who was very appropriate did give me a address to mail a complaint which i will but being a disabled veteran of the Iraq war and a member of the wounded warrior project i get upset at certain people who show no respect for the average person and even worse of an attitude to those injured serving their country. I'm in no way saying I'm better its just that i expect a grain of respect as a person, a fellow American working everyday just to get by. my issue was not an impossible issue to resolve but i was told by one rep that it was not possible after my call being "dropped" i called back and talked to another. Luke from call center Washington state told me it was possible but that the phone i ordered two days prior (that rep failed to finish the order)was no longer available and i could pick a different phone not on back order.......i mentioned my confusion to the lack of service and being told two separate things. i asked why this was when i was not the one who made the mistake he told me it was not there fault and pushed the blame to me....he then called me dude and started to speak over me. when i asked to speak to a supervisor he asked why i told him i was no longer interested in talking to him he said why, i asked to be transferred again he kept refusing saying listen man I'm trying to help you what do you want. i asked to speak to his supervisor at least three more times he refused. i asked for his employee information so i could call back to report his rude behavior he refused to give me anything except at the end he finally told me his name.. there is more but my hand is tired is there anyone who can help me? if i find an answer as i will be posting this to many sites i will post it here.

Mark th

Buy the "AT&T" model iPad, not the Verizon one (which does not support SIM cards used most everywhere in the world). The ATT model comes with a SIM card, but you can then get one from a UK provider. Be sure it's a "microSIM" card, not the larger kind when back in the UK.
