Problem regarding updation of Z-table through maintenance view

hi ,
I m facing problem in updation of Z-table through maintenance view (SM30).
The scenario is that I have one customizing field in my Z-table which is checkbox.
Now I need to populate 2 fields in Z-table on tick of this checkbox and clicking of SAVE button.
For this I have created one module ''change_field'' in PAI.
Actually my database table is being updated but as soon as the control left my module all the updation that take place vanishes away.....
So please help me in this matter.

Thanks for ur previous effort it is updating the database but its effect is not shown immediately on screen.After i referesh the transaction it is dispalying the data.
So can u please suggest me any way....
Now i have one scenario infront of me....
I need to restrict the data shown in maintenance view.
I think it would be same as pop-up window displayed when we tick on 2nd radiobutton ("ENTER CONDITIONS")
of intial screen of t-code SM30.
Please suggest what shud i do....
Thanks and reagrds,
Amit

Updating a Base Table through a View having UNPIVOT function.

Hi,
I have a requirement of updating a Base Table through a View.
This View has the query using a UNPIVOT function for displaying the columns of the Base tables in rows.
I need to update/insert into/delete the Base Table by accessing the View (The user doesn't have an access to the Base Table, hence the DML's on the View).
Following is the table I've created:-
CREATE TABLE PERSON_DETAILS
PID            VARCHAR2(10 BYTE),
FIRSTNAME      VARCHAR2(1000 BYTE),
LASTNAME       VARCHAR2(1000 BYTE),
PHONENUMBER    VARCHAR2(1000 BYTE),
ADDRESS1       VARCHAR2(1000 BYTE),
ADDRESS2       VARCHAR2(1000 BYTE),
COUNTRY_CODE   VARCHAR2(1000 BYTE),
LANGUAGE_CODE VARCHAR2(1000 BYTE),
EMAIL          VARCHAR2(1000 BYTE)
)The sample values are inserted in this table through the below script:-
insert into person_details values ('1','XYZ','ABC','1234567890','India','Asia','IN','EN','[email protected]');
insert into person_details values ('2','XYZ2','ABC2','1234567890','India','Asia','IN','EN','[email protected]');The code for the view is as below:-
CREATE OR REPLACE FORCE VIEW PERSON_DETAILS_VIEW
   PID,
   CD_NAME,
   CD_VALUE
AS
   SELECT "PID", "CD_NAME", "CD_VALUE"
     FROM person_details UNPIVOT INCLUDE NULLS (cd_value
                         FOR cd_name
                         IN (firstname AS 'First Name',
                             lastname AS 'Last Name',
                             phonenumber AS 'Phonenumber',
                             address1 AS 'address1',
                             address2 AS 'address2',
                             country_code AS 'Country Code',
                             language_code AS 'Language Code',
                             email AS 'Email') );Below are the values from the view:-
PID CD_NAME         CD_VALUE
1    First Name       XYZ
1    Last Name       ABC
1    Phonenumber 1234567890
1    address1         India
1    address2         Asia
1    Country Code   IN
1    Language Code EN
1    Email               [email protected]
2    First Name       XYZ2
2    Last Name       ABC2
2    Phonenumber 1234567890
2    address1         India
2    address2         Asia
2    Country Code   IN
2    Language Code EN
2    Email               [email protected] user would fire some statement like below:-
update person_details_view
set cd_value = 'US' where CD_NAME = 'IN'The above statement should update the base table PERSON_DETAILS.
I understand I can write an INSTEAD OF trigger but I do not know what logic to write in the trigger so that the requirement gets fulfilled.

it is definitively possible with an instead of trigger.
for Example:
create or replace
TRIGGER ioft_person
INSTEAD OF UPDATE
ON person_details_view
FOR EACH ROW
declare
firstname1 person_details.firstname%type;
BEGIN
              SELECT firstname_new into firstname1
              FROM   (SELECT pid, cd_name, cd_value
                      FROM
                              select * from person_details_view where (pid, cd_name) not in (select :new.pid, :new.cd_name from dual)
                              union all

                                                        'address1' as address1,
                                                        'address2' AS address2,
                                                        'Country Code' as country_code,

                                                        'Email' as email
              ) where pid = :old.pid;
UPDATE person_details
SET firstname = firstname1
WHERE pid = :old.pid;
END ioft_role_perm;and than run
update person_details_view
set cd_value = 'X|X' where cd_name = 'First Name' and pid=1The logic is: you must convert back the view through pivoting

ORA-02070: Error when updating an informix table through orcl view using HS

Hello!
I faced the following problem:
I have a table in informix, and i want to reach this table through Oracle infromix gateway (Heterogenous Services). I succeeded to set up the gateway, and I created an Oracle view for my table in informix. It is working fine, I can query and modify data, except the following case: If I run the query (from SQL Developer) "UPDATE oracle_view SET float_field = '1.1' WHERE record_id = 1 AND float_field = '1.2'", I receive the following error:
"SQL Error: ORA-02070: database database_link does not support TO_NUMBER in this context.
*Cause: The remote database does not support the named capability in the context in which it is used.
*Action: Simplify the SQL statement."
If I modify the query as "UPDATE oracle_view SET float_field = '1.1' WHERE record_id = 1", it is running without any error messages. I found, that to_number is not supported by Oracle HS gateway, but I do not use explicitly the to_number Oracle function! But I must use the above version, because of concurrent users.
Does anybody have an idea how I could get rid of the implicit call of to_number?
Thanks, Gyula

user11229789 wrote:
Yes, float_field is a numeric-type field, which is a 8-byte FLOAT in informix. This field gets automatically FLOAT datatype in the Oracle view, and can not be modified. record_id is some integer unique id field.Well, as the float_field is numeric it makes sense that the SQL issued from Oracle treats it as numeric, so leaving out the quotes can only be the correct thing to do. If you introduce quotes then you are providing strings and the HS is having to do a convertion to numeric (hence where the TO_NUMBER would have been coming into the initial issue.
If I try the update query without '-s you suggested, like this: "UPDATE oracle_view SET float_field = 1.1 WHERE record_id = 1 AND float_field = 1.2" , i receive the following error message:
SQL Error: ORA-28534: "Heterogeneous Services preprocessing error"
*Cause: One of the things that the Heterogeneous Services can do is
to preprocess parts of SQL statements that contain implicit
coercions or calls to explicit coercion functions like TO_CHAR
TO_NUMBER or TO_DATE. For example, it could convert a call to
TO_DATE to a bind variable, pre-evaluate the TO_DATE function
call and pass the resulting value to the non-Oracle system as
the bind value. This behavior is controlled by some coercion
related capabilities. If the capabilities are set incorrectly,
the HS could encounter errors when it attempts to do the
preprocessing. If it does then this error will be signaled.
*Action: The capability table settings are controlled by the agent
vendor and can be modified by the DBA. Contact your DBA and
agent vendor and get the correct set of capabilities installed.I can't see why the HS would be trying to do any coercion of anything except to perhaps convert the parts of the where clause to bind variables and pass the actual values in. Does it work ok without the "AND float_field = 1.2" ? If so, I'm guessing there's some configuration issue of the HS required to get it to deal with the floats.... perhaps in the capability settings as the error message "action" indicates.

Problem regarding the creation of Table using CSS.

Hi ,
Here I have a Problem regarding the creation of Table using CSS.
In My Application i have a table with multiple rows(Rows are Dynamically added to the table).First i am setting the table with the following properties:
width:900px;
height : auto,
Overflow : visible,
Max-height: : 200px.
If I use above properties,I'm getting a table with 5 or 6 rows(height upto 200px).After that i am getting the Vertical ScrollBar.
The problem is when a table has many columns, Vertical and Horizontal Scrolls are coming at the time of setting the table. The table height is not Increasing dynamically.
How can i use "height" property in CSS? (I want the table height to be increased when the columns are more.)
Thanks & Regards

Regarding updating of database table..

Halo All,
I have actually done the program successfully for updating the database table QMFE some days back, now we needed to update some more records and i have just changed the path of the text files but the problem is that all the values are being uploaded but the update statement is not executing successfully
I have also tried to debug the program and saw that the sy-subrc value is 4 instead of 0.
I am pasting my code here.
Please solve this asap.

Hi,
Thanks for the reply..
But last time the update was successfull and the program was transported onto the productive system
after that now i need to update the new records into QMFE
so what i did is just changed the path of the text files since they are of same format as of the old text files.
Does it have any problems.

Problem while updating a database table

Hi experts,
I've used the FM 'HR_INFOTYPE_OPERATION' to update the database table. In that i used the MOD operation to update the Infotype PA0315. But it return an error message like "Infotype does not exist". What could be the reason for this error?.

Is there a restriction on deleting data from an table through a view?

I have an Oracle Forms application where, try as I might, I cannot delete records based on a view. I know that the restriction may be because of Forms but, is there a database level restriction on deleting records through a view?

try as I might, I cannot delete records based on a view. Do you get an error?
There are several restrictions about deleting via a view:

Problem in updating entries in Table Maintenance of custom table

Hi Gurus,
Need help. When I update existing entries in the table maintenance generator, they do not get updated after save. Is there a setting in data dictionary that causes this?

Just noticed that the field that I'm trying to update is a KEY FIELD.
Usually, when a table maintenance is generated, key field columns are set to uneditable. But for apparent reason, previous programers set it as editable. Is there a way to edit the Key fields?

Problem regarding Update-Statement on se11 table

Hello I tried to update a dataset in a se11 table using UPDATE Statement.
It doesn't work and I get a sy-subrc = 4.
That is my code:
TABLES ZTDM_SAPOUTPUT.
* Arbeitsbereich definieren
DATA:
wa_ZTDM_SAPOUTPUT LIKE ZTDM_SAPOUTPUT.
wa_ZTDM_SAPOUTPUT-PK = '1'.
wa_ZTDM_SAPOUTPUT-FNCODE = '3'.
wa_ZTDM_SAPOUTPUT-MATNR = '3'.
wa_ZTDM_SAPOUTPUT-MAKTX = '3'.
wa_ZTDM_SAPOUTPUT-ZEINR = '3'.
wa_ZTDM_SAPOUTPUT-MATKL = '3'.
wa_ZTDM_SAPOUTPUT-STATE = '1'.
UPDATE ZTDM_SAPOUTPUT FROM wa_ZTDM_SAPOUTPUT.
Write: 'UPDATE returned' , sy-subrc.
SKIP.
The given Dataset having PK=1 doesn't get updated.
Maybe my understanding is wrong:
Is it correct that the updated dataset ist defined by the primary key in this workingarea?
My Primary Key is PK.
Can you see the error?

UPDATE dbtab FROM wa. or
UPDATE (dbtabname) FROM wa.
Changes one single line in a database table, using a primary key to identify the line and taking the values to be changed from the specified work area, wa. The data is read out of wa from left to right, matching the line structure of the database table dbtab. The structure of wa remains unchanged. This means that wa must be at least as wide (see DATA) as the line structure of dbtab, and have the same alignment. Otherwise, a runtime error occurs.
If either the database table, dbtab, or the work area, wa, contain Strings, wa must be compatible with the line structure of dbtab.
Example
Changing the telephone number of the customer with customer number '12400177' in the current client:
DATA wa TYPE scustom.
SELECT SINGLE * FROM scustom INTO wa
WHERE id = '12400177'.
wa-telephone = '06201/44889'.
UPDATE scustom FROM wa.
When the command has been executed, the system field SY-DBCNT contains the number of updated lines (0 or 1).
Examples
Update discount for the customer with the customer number '00017777' to 3 percent (in the current client):
DATA: wa TYPE scustom.
SELECT SINGLE * FROM scustom INTO wa
WHERE id = '00017777'.
wa-discount = '003'.
UPDATE scustom FROM wa.
The Return Code is set as follows:
SY-SUBRC = 0:
The specified line has been updated.
SY-SUBRC = 4:
The system could not update any line in the table, since there is no line with the specified primary key.

Urgent: Customized Routine Problem: Not updating related databse tables.

Hi Gurus,
We made some changes in customized routine of pricing condition type.
Requirement :
"A" condition type which is appearing in pricing of sales order which we want to be split into Billing document i.e.in Invoice. The amount should split as per the invoiced quantity,. Earlier it was redeterminig from condition master"
Logic in routine:
"we are checking respective sales order for Invoice. From Sales order value we are finding out document condition number in VBAK table. then in KONV table for respective value we are checking "A" condition type is available or not.
If it is available we are just copying the value and depending upon the Invoiced qty, We are passing to the same condition type.
Problem:
Value is appearing in Invoice document but it is not updating the related database tables e.g. KONV for(Invoice document condition No.)

A problem with updating a production tree through the DI

Dear all,
I'm trying to update 2 properties of a production tree through the DI - ToWH and PriceList.
I'm using the next code:
SAPbobsCOM.ProductTrees tree = (SAPbobsCOM.ProductTrees)mCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oProductTrees);
Then, this tree object doesn't give me the option to update the pricelist and the target warehouse, although it is possible to do so through the UI.
Any ideas?
Thanks!

Hi,
If the DI API does not expose the properties then it may not be possible at the moment. However, I have sometimes found that if you use the XML interface in the DI API that you can update properties that aren't exposed through properties in the DI API objects.
Try something like this:
1) Use the GetByKey method of the production tree object to get the BOM you want to update.
2) Use the GetAsXML method to generate an XML formatted string of the BOM
3) Load the xml string in to an XML parser such as the XMLDocument object in the .NET Framework
4) Use the XMLDocument object to update the header fields you want to change and save the xml string as a file to disk
5) Use the GetBusinessObjectFromXML method of the DI API company object to load the XML file back in to your production tree object
6) Call the Update method of the production tree object
If that doesn't work then there is no way I know of to achieve what you want through the DI API.
Kind Regards,
Owen

Problem while Updating in Advanced Table!

Hi All,
I have a page with Advanced Table. All values are populating from View Object (Entity Based).
Scenario - When i make modifations in a row and press Commit button. Changes performed are not reflected in database table.

Problem regarding the transmission of video Through TCP/IP acquired from USB camera

I want to transmit video using TCP/IP protocol acquired from USB camera. Acquisition is done well but when I place the TCP VIs in the acquisition VI then the trouble begins and I can’t even get the video in that particular VI which was acquiring video and working fine previously.
Interesting thing is that both Cam Server and Cam Client VIs was transmitting video in the very first run. After that I don’t know what happened.
I am using lab view 8.2.1.VIs are attached.
Please help me out.
Regard,
Aftab

Hi Shoaib,
Here's an example I was testing mixing IMAQdx and the Simple TCP/IP Messaging Protocol (http://zone.ni.com/devzone/cda/tut/p/id/4095) to send up a video client/server app with a USB camera that I was testing with.
