Read data from maintenance view

hi all,
could anyone please tell me if there is any special way to read data from a maintenance view (if at all it is possible).
i wrote a simple select on it but it gave me a syntax error that the view is not defined in the dictionary. (i am able to see the view definition by double clicking and it is active too).
the following is my select.
select single lgnum from v_t320 into (w_lgnum) where werks eq p_i_werks and lgort eq p_i_lgort.
awaiting answers...
regards,
PJ

Thanx Rich,
but the documentation on maintenance views says that we can have read access to them. Does that mean the data can only be seen via the DDIC and not from a select written in a program??
this is what i read...
Maintenance Status
The maintenance status of a view controls whether data records can also be changed or inserted in the tables contained in the view.
The maintenance status can be defined as follows:
Read only: Data can only be read through the view.
Read, change, delete, insert: Data of the tables contained in the view can be changed, deleted, and inserted through the view.
Only read access is permitted for database views that are defined through several tables. If a database view contains only one single table, data can be inserted in this table through the view (see Inserts Through Database Views).
The following status definitions are also possible for maintenance views:
Read and change: Existing view entries can be changed. However, records cannot be deleted or inserted.
Read and change (time-dependent views): Only entries whose non-time-dependent part of the key is the same as that of existing entries may be inserted.
you surely have earned some points here....just let me be clear of the concept behind this

PJ

How Can i Read data From Maintainance View

I Want read data from Maintainance View. i written select query
SELECT *
FROM J_1yyyyV
INTO TABLE GT_BUSPLACE.
WHERE BUPLA = LV_BUPLA.
this is giving following error
"J_1yyyyV" is not defined in the ABAP Dictionary as a table,
projection view, or database view.
Can you help me Please.
Thanks in Advance.
Regards,
Raj.

Hi raj,
maintainance view is a nothing but combinations of table using join on some fields..
see the relation ship between the joins..
if you want to write selection query ..go to se11 -->enter view name >and open tab>
Table/Join conditions--> see the table's involved and join conditons between tables.
and write the select query same as like the Table/Join conditions in se11..now you can acheive the
table maintainance fields..

How to extract data from maintenance view

Hi experts,
How can I select the data from maintenance view. As you know select query doesn't work on the maintenance view. And View name will be known at run time only.

Select query to read data from a view

Hi friends,
We have been using a query to read data from a custom view which used to work perfectly. Now the program sits at that select query forever. We are able to extract same data from se16. Not sure what could be the problem.
Thanks in advance.

Dev
Have a look at the Table Index for the tables involved in the View... I think there is some change in the Indexes.. (Add / Remove / Change)
Thanks

Reading data from maintainance view

hi ,
Can we read the data from maintainance view through select statement.

Hi again,
1. V_001K_K
   Since this view comprises
   more than 1 table
T001K
T001
It gives this error.
2. Maintenacnee views comprising only 1 table
   can be used in Select.
For eg. V_T001
V_T003 = Not allowed
PS:
3. The reason for this is :
   Any R/3 view having only one table,
   for such view, a physical view is created
   in the database.
   The records in it can be modified, inserted,deleted.
   (conditions apply)
   But for view having 2 or more tables,
   no physical view is there in the database.

IC WebClient: Reading data from different views

In the view SrvTHead I intend to develop a PDF file which contains information from the views SrvTProduct, SrvTExtras, SrvTPartner, SrvTText, FoUpText and FollowUpDetails.
From the Cookbook I have learnt that this is possible using custom controllers.
Example:
data: bdc TYPE REF TO cl_crm_ic_cucobdc_impl.
bdc ?= me->get_custom_controller( 'CuCoBDC' ).
current_one_order = bdc->typed_context->currentoneorder.
current_inboxitem = bdc->typed_context->currentinboxitem.
lv_col_wrapper = current_one_order->get_collection_wrapper( ).
lv_current = lv_col_wrapper->get_current( ).
lv_col_wrapper1 = current_inboxitem->get_collection_wrapper( ).
lv_current1 = lv_col_wrapper1->get_current( ).
I am not sure how to proceed after this...
Has anyone implemented this before?
Thanks,

Hi experts, how to use open sql to read data from one " maintenance view"?

i want to use this part of data within report ,so how to use open sql statement to read data from one " maintenance view"?

Hi
You can't use OPEN SQl statements to fetch data from maintenance view
You have to use only Database views
see the different types of views and the difference
The followings are different types of views:
- Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
- Help View ( SE54)
Help views are used to output additional information when the online help system is called.
When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
- Projection View
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
- Maintenance View ( SE54 )
Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Please have a look at below link. It will help you.

Is it possible to retrieve the data from maintainance view?

Hi experts,
Am facing one problem.
Is it possible to retrieve the data from Maintainance View ,If yes how?
IF it is not possible then Y?
While am trying to retrieve data from maintainance view it's showing message like
"it is not a database view or table".
Can u pls give me ans.
Thanks&Regards,
Arun.

Hi Arun,
It is not possible to retrieve the data from Maintenance view. Maintenance View is different and Database View is different.
Maintenance view : Maintenance view permits you to maintain the data of an application object together.The data is automatically distributed in the underlying database tables.
A standardized table maintenance transaction is provided (SM30), permitting you to maintain the data from the base tables of a maintenance view together.
In other words, Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Database View: Data about an application object is often distributed on several database tables. A database view provides an application-specific view on such distributed data.A database view is automatically created in the underlying database when it is activated.Database views implement an inner join.If the database view only contains a single table, the maintenance status can be used to determine if data records can also be inserted with the view. If the database view contains more than one table, you can only read the data.
Database views should be created if want to select logically connected data from different tables simultaneously. Selection with a database view is generally faster than access to individual tables. When selecting with views, you should also ensure that there are suitable indexes on the tables contained in the view.
Hope this helps.
Please reward if useful.
Thanks,
Srinivasa

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

Reading data from View

HI all,
Can anyone help me please. I want to read data from view with below simple program
Report zread_view.

ENDLOOP.
But when activating this message is show:
'V_T053" is not defined in the ABAP Dictionary as a table, projection view, or database view.
Need for anyone help...?
Thanks,
Ramses

hi,
which view you are accessing in the program? you can able to access only database view and projection view from prgram.
the view which you are using in the program is niether database view nor projection view. that is why you are getting that error message ''V_T053" is not defined in the ABAP Dictionary as a table, projection view, or database view".
hope this will help you.

Is possible to represent data from a view in MapViewer?

I have tried to represent data from a view instead a table with the Java-Beans API but I couldn't beacause it doesn't represent any geometry referenced by the view. I think it should be implemented because is very common to use views. Are there any way to represent them in MapViewer?
Thanks.

Like a table, you also need to register the view in spatial metadata (user_sdo_geom_metadata). Did you register the view and its spatial column there?

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;
using System.IO;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Diagnostics;
using System.Linq;
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;
try
listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
LoggingProvider.Logger.Info("This is what the host sent to you: " + input+". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));

catch (Exception e)
LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
break;
catch (Exception ex)
LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
break;
}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try

Help Required -- Can we use SQL Query to READ data from SAP MDM Tables

Hi All,
Please help.........
Can we use SQL Query to READ(No Creation/Updation/Deletion just Read) Data from SAP MDM tables directly, without using MDM Syndicator.
Or direct SQL access to SAP MDM tables is not possible. Only through MDM Syndicator can we export data.
Thanks in Advance
Regards

All the tables you create in Repository comes under A2i_CM_Tables in Database named as your repository name. So the tables names are fields of table A2i_CM_Tables. Now i tried it but cant make it.
Now, I dont think its possible to extract all fields in tables and there values using select query. May be pure sql guy can do that or not.
But there is no relation of data extraction and syndicator. Data is viewed in Data Manager. and you can also store data in a file from DM also.
