Tables and webservices

I have created a webdynpro application based on a webservice. This webservice creates a quotation in a legacy system. The quotation/webservices has one header line and several item lines.
I imported the WS in the NW Dev Studio 2.0.9 and have the structures and methods available to read and create a quotation.
Reading was simple with the NW Dev templates for Form, Table and Action Button I created the view and it works fine. ( I also have a quotation list view and from that view I can navigate on row selection to the quotation view.)
Now I want to create a new quotation. The view looks almost the same but I dont know how to add, modify and delete items to the table. The CarRental example looks the same but it adds the items to the table via the WS. I want to compose the complete set of header and item data first and then call the WS.
I cant figure out how to use the wdContext object to do this. There is hardly any documentation about this.
Does anyone know of a good sample how to do this?
Thanks a lot in advance!

API and WebServices

What is WebServices and API in MDM? How both are linked to each other when you are doing ABAP API in the real time scenarios?
Thanks in Advance,
Best Regards,
Vijay

Hi,
Web services for MDM are open interfaces to the MDM Server. They provide data management capabilities (create, read, update) and access to central key mapping (create, read). MDM Web Services provide synchronous access to MDM for the consumer of the Web services.
The MDM Web services can be used to:
● Manage Master Data Objects
○ Existence check of a central master object before local creation
○ Retrieve details and create a local replicate
○ Create or update master data objects on MDM
● Manage Unique Identifiers of Master Data Objects
○ Remote system registers local object as replicate of global object
○ Key mapping during message exchange on SAP NetWeaver XI
Also MDM Web services provides the following Web service categories:
● Key Mapping Web services
To create and retrieve key mapping information for MDM records
● CRUD (Create, Retrieve and Update; Delete not yet provided) Web services
It exposes MDM's rich functionality in searching for records and maintaining data in records (for example, main table, lookups, qualifiers).Another category of Web services, developed to support MDM Customer Data Integration (CDI), is the Business Partner (BP) CRUD Web services. In contrast to MDM CRUD Web services that are schema-independent, the BP Web services are hard-wired to MDMs Business Partner repository/schema. Schema changes require the adaptation of the interface and of the code of the BP Web services.
API
The MDM ABAP API provides an interface for accessing SAP MDM 5.5 using ABAP. The interface is easy to configure and convenient to use.It is optimized for ABAP developers and available using ABAP Objects and function modules (partly remote enabled). In addition to the core services performed on the records (create, retrieve, update, delete, query, etc), metadata (tables, fields, etc.) and administrative functions (such as repository) are delivered.
The MDM ABAP API empowers ABAP-based applications to control MDM Servers using most of the functions available in the MDM Console and MDM Data Manager applications.
The API is provided with:
● Interfaces and methods (ABAP objects)
● Function groups and function modules
The interfaces with the extension SIMPLE have the following advantages:
● Simple and comfortable access
● Generic and object-oriented
● Methods use DDIC structures (no arrays, but tables and fields)

Tables and Files

Hi...
I'm calling a webservice that returns a string to me.
This return, I'm putting into a context, and I'm showing them into a table.
The values of this context (table), contains a title (that is showed in table) and a value (this value is not showed in table).
I need to create a button, that create one text file for line, zip it, and starts to download....
How can I do this?!
Thanks in advance.

Just because excel accepts this format, does not mean it is a valid csv.
See this other specification: http://tools.ietf.org/html/rfc4180#section-2
1. Each record is located on a separate line, delimited by a line
break (CRLF). For example:
aaa,bbb,ccc CRLF
zzz,yyy,xxx CRLFI think the only way to read in such files is to replace the record delimiter with something different. Some rule like always break after three fields. Not sure if the positional syntax allows for this, but you could check the SQl*Loader docs, which might have examples that go into this direction.
Edited by: Sven W. on Aug 3, 2009 4:58 PM
Another possibility is if the record delimiter line break and the line break inside one field are different. For example if the record delimiter is a CR+LF = CHR(10)||chr(13) and the field line break is a CR only = CHR(10). THis might depend a lot how the field line breaks are created.
You also might be able to do some preparation in Excel first to create special line break chars (search and replace stuff).

Expose Table as Webservice

I am trying to create a internal web service that will return a recordset based on filter.
Platform JDev 10g
1. Made Database connection.
2. Created new application. (JSP, Struts, EJB)
3. Created Model Diagram. (Which Diagram should I create.)
If I choose web service Diagram I cannot drop my table view onto diagram.
4. ? using When I drag the Table onto the Diagram. Do I create a EJB or Java Class. I ask this because only Java Classes can be made into WS.
What steps do I need to take to expose a table as a webservice???

Eric,
You can't publish a table as a web service directly,
You'll need some code that access the table and then you'll publish this code as a Web service.
The code can be a simple Java class doing JDBC calls, a BC4J component, and EJB or even a PL/SQL stored procedure that you publish as a web service.
Here are some tutorials that might help:

How to use one query against multiple table and recieve one report?

I have duplicate tables, (except for their names of course) with commodities prices. They have the same column headings, but the data is different of course. I have a query that gives me a certain piece of information I am looking for but now I need to run this query against every table. I will do this every day as well, to see if the buying criteria is met. There are alot of tables though (256). Is there a way to say run query in all tables and return the results in one place? Thanks for your help.

hey
a. the all 256 tables whuld be one big partitoned table
b. you can use all_tables in order to write a select that will write the report for you:
SQL> set head off
SQL> select 'select * from (' from dual
2 union all
3 select 'select count(*) from ' || table_name || ' union all ' from a
4 where table_name like 'DB%' AND ROWNUM <= 3
5 union all
6 select ')' from dual;
select * from (
select count(*) from DBMS_LOCK_ALLOCATED union all
select count(*) from DBMS_ALERT_INFO union all
select count(*) from DBMS_UPG_LOG$ union all
remove the last 'union all', and tun the generated quary -
SQL> set head on
SQL> select * from (
2 select count(*) from DBMS_LOCK_ALLOCATED union all
3 select count(*) from DBMS_ALERT_INFO union all
4 select count(*) from DBMS_UPG_LOG$
5 );
COUNT(*)
         0

How to disable a single cell in a table (and not the whole column)

Hi there,
I've got a webdynpro table with a few columns, rows can be created dynamically through a button in the table toolbar.
Depending on the value of a certain cell I have to disable another cell (in the same row).
I tried to manipulate the view in the modifyview but no joy. I also tried to manipulate the attribute property through the coding below:
DATA lv_knttp TYPE knttp.
lo_nd_kostl = wd_context->path_get_node( path = `MULTIVALUES.KOSTL` ).
lo_el_kostl = lo_nd_kostl->get_element( ).
lo_el_kostl->set_attribute_property(
attribute_name = 'LTEXT'
property = lo_el_kostl->e_property-enabled
value = ''
but it disables the whole column!!!! I just need the cell to be disabled (I thought the code above, through the lead selection, would affect a certain cell only - but I was wrong).
Any ideas?
Thanks!!!

Hi,
using cell variants you can do this.,
check this article: [Cell Variants in WDA|http://wiki.sdn.sap.com/wiki/display/WDABAP/WebDynproforABAPCellVariants]
Instead of binding the read only property of table as a whole , just bind the read only property of column group of table., You can do this bu drill down the table and select the required column and bind the read only column.,
then In onAction Event of button .,
loop the table, if condition satisfied set the read only property to true else false.,!!
hope this helps u.,
Thanks & regards,
Kiran

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:v="clr-namespace:CCIS.View.Case"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
d:DesignWidth="300"
d:DesignHeight="200">
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:vmPetitioner}">
<v:vPetitioner Margin="0,2,0,0" />
</DataTemplate>
</UserControl.Resources>
<Grid>
<HeaderedContentControl>
<HeaderedContentControl.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock Margin="2">
<Hyperlink Command="{Binding Path=AddPetitionerCommand}">Add Petitioner</Hyperlink>
| <Hyperlink Command="{Binding Path=DeletePetitionerCommand}">Delete</Hyperlink>
</TextBlock>
</StackPanel>
</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>
''' Common functionality for ViewModels of an individual ContactDetail
''' </summary>
Public MustInherit Class vmParty
Inherits ViewModelBase
''' <summary>
''' Gets the underlying ContactDetail this ViewModel is based on
''' </summary>
Public MustOverride ReadOnly Property Model() As tblParty
'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on
'''' </summary>
'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.

What the difference and use between   of TABLES and SY-REPID?

Hi,
Experts,
I have came accross 2 cases that i can't able understand
EX1:
TABLES: VBAP   -
>( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP but, by
data: v_vbeln like vbap-vbeln.    double clicking on variable v_vbeln AS taking me to DDIC VBAP table VBELN field then what the using declaring tables. )
( and )
DATA: VBAP TYPE VBAP -->( Here also Appplication Server(AS) creates Wrokarea of Structure VBAP data: v_vbeln like vbap-vbeln.    but,double clicking on variable v_vbeln AS taking me to user declared VBAP
                                              i.e., above DATA declaration statement )
Then Which one is better in Functionality wise as well as Performance wise or when we have to go for TABLES and when we have to go for DATA declaration of DDIC objects.
EX2:
what the difference between
I know that SY_REPID is not a system variable. And also that
Data: vrepid type SY_REPID.--> Predefined data type in ABAP
and
Data: vrepid like SY_REPID.-> Predefined Constatnt in ABAP( it is a constant it allowing with out VALUE
attribute)
what difference between them and when we have to go Data: vrepid type SY_REPID and when we have to go Data: vrepid like SY_REPID.
Thank U,
Shabeer Ahmed.

Hi Ahmed,
TABLES:
VBAP.   " DDIC
DATA:
v_vbeln like vbap-vbeln.
*Here you are using the DDIC VBAP
DATA:
VBAP TYPE VBAP.
DATA:
vbeln like vbap-vbeln.
*Here you are using the local data object as your data type so it will always
* take you to user declared VBAP which is declared by you.
DATA:
T_VBAP TYPE VBAP.
DATA:
vbeln like vbap-vbeln.
* here its using T_VBAP not DDIC VBAP
And for performance always the second option is better, use Data instead of tables, declare your own local structure.
Data:
vrepid type SY_REPID. thereis nop redefined data type in ABAP as SY_REPID
* its SY-REPID which is a system variable.
Data:
vrepid type SY-REPID.
Also refer to the links:
Difference between tables statement and by using type statement

Difference between Temp table and Variable table and which one is better performance wise?

Hello,
Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
Which one is recommended to use for better performance?
also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
Is that Table variable using Memory or Disk space?
Thanks Shiven:) If Answer is Helpful, Please Vote

Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
But it also depends upon specific scenarios you are dealing with , can you share it?

HELP! FOR LOOP TO SCROLL THROUGH TABLE AND CREATE DATABASE LINK

Hi,
Here's the scenario, not much of a PL programmer, just basic SQL so really need some help people!
I have 2 tables. 1 contains list of DB's and the other contains rules to follow.
I need to create a loop that goes through the table containing the DB's and on each row a DB link is created (Only 1 link allowed!)
Once created, the schema currently logged in with also has an account on the linked DB in order to run scripts- The scripts are stored centrally hence the requirement for the link to the target DB.
There are numerous scripts that need to be executed and can all be called from 1 script, once executed the loop exists and the database link needs to be dropped.
Once dropped, the first loop continues, creating a DB link for the next DB listed in the table (and all the scripts are fired again)
This continues against all the DB's listed in the table.

Hi BlueShadow,
Thanks again for the response, you've hit the nail on the head. SQL scripts on a unix server, a loop goes through a table 1 at a time. Each row gets a link created and then all the scripts stored on the server are executed against the db linked to. So I'm assuming this is a loop within a loop.
1 loop to go through the table to create the link and then another loop within once connected to execute all the scripts against the connected DB. Once the scripts are run, the loop exits and moves onto the next server and so on until all the servers have the scripts are run.
It's PL/SQL scripts we're after and not shell scripts as this would free us from the OS constraints.
We have to drop the links due to security. Any idea on o

Hello Happyman,
<b>What do you mean by Protect Table, Program and Report?</b>
Let me ask you one base Question, On which area are you working? Are you from functional side or Technical side (Developement or Basis guy)?
This is very clear cut answer that with the restricted autorization you can protect table and programs. Do not provide the change autorization.
CATCH your BASIS guy and he will do rest of the things. Just explain him what are you want to protect.
Hope this helps.

Interactively changing values to table problem: indicator and control table, and why it does not work after a while...?

I have been producing a VI that loads a set of data and displays it in a table: A table control is initialised with an empty variable, the loaded data takes the place of the variable and fills the table, while some headers are added. That table feeds an intensity graph to give a pictorial impression of the data.
With this scheme, a user can change any value of the table, and the changes are interactively reflected on the graph.
Problem: after few saving of the VI, the access to the table doesn't work anymore. It is the same with all my numerical controls in the VI where it should be possible to enter a value.
If anybody has an idea on the potential
causes of these problem, I would be really grateful as it is very useful...when it works !

Elie Allouis

I can not image what is causing the error. Would you be willing to post some code to see if we can reproduce the problem?
