Hi,
You can Direct Use the DML operations on the Underlying Database Table.( example 'SELECT' Statement and use 'WHERE' Condition for required output ).

Querying data from the maintenance view.

Hi Experts,
Well, i need the STEXT field value from the maintanance view V_T591A created for the standard table T591A.
Table T591A has the field Subtype but doesn't have the field Stext, which consists the description of the subtype. The Stext field is there in the maintenance view V_T591A.
So, if i want to query the respective description of the specific subtype, how do i get the values from the maintenance view?
Please advice.
Thanks in anticipation to all!
Cheers,
Sundar.

Atish,
It is not possible that way! U cannot Query directly from MV as a DB table.
Anyways, i managed to find the answer.
Thanks though.

Query Regarding fetching selected records from table

Hi All,
I have a table like below:
NUM1     NUM2     TYPE
1     2     A
1     2     S
2     3     S
3     4     A
3     4     S
4     5     S
If for a record TYPE='A' then do not select the records for those num1 and num2.
Eg: for num1=1 and num2=2 there are two records with type='A' and 'S', only records with type 'A' should get selected.
Output should be like this:
NUM1     NUM2     TYPE
1     2     A
2     3     S
3     4     A
4     5     S
Please anyone could help me in this query.
Any help would be highly appreciated.
Thanks & Regards

Query on Maintenance Views

Hello Experts,
Can we query on (using select statement) on a maintenance view?
Thanks.

Hi,
No you can't. Better query the tables from which view is created.

Regarding maintenance views

what is the main purpose in creation of maintenace views???????
and where we use it in real time?????

Hi
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.

Creation of Views:
1.Go to se11
2. select view radiobutton and give a name
3. Create
4. select type of view you want to create. Such as database view.
5. give short description
6. give a table name such as mara
7. press the pushbutton relationship. here you will find all the tables which are allowed to create view with mara.
8. select one or mane tables.

How to capture the data that the user modified in SM30(Maintenance view)

Hello experts,
I have a new requirement wherein when the user modifies a particular record in SM30(maintenance view)
it would also update that certain records in another table. For example, I modified the address
of record 1 in table1 so I need to automatically update that same record in table2. Help would be greatly appreciated.
Again, thank you guys and have a nice day!

Hi again,
1. But how can I capture the data that was modified
Yes, u are right.
We will have to use the event,
'BEFORE SAVING'.
2. In that,
u must fire a select query,
   from the same table,
   for the same record.
3. In this, u will get the OLD DATA (which was already saved),
4. Using this,u can compare,
   (either thru LOOP, or field by field)
to know, which field value has been changed.

[Maintenance View] Mass maintenance of Z-Table

Hi,
I was wondering what were the options when dealing with mass maintenance of Z-table entries.
SM30 is OK for maintenance view but you cannot process more than a given number of lines (34 entries or so) per page.
Ideally, it should be possible to enter data from Excel file of even clipboard.
SE16N is great for this since it allows pasting of clipboard data but it does not work with maintenance views (it switches to the SM30 dynpro).
Besides, if I create a database view, it is not possible to save entries because it joins several table together (even if I only need additional fields for display only).
I tried the FM 'SE16_INTERFACE' but it dumps with an CX_SY_DYNAMIC_OSQL_SEMANTICS error (SAPSQL_NO_DBTAB_OR_VIEW). (you can only query table or database view but no maintenance view)
Thanks in advance for your ideas/advice.
Best regards,
Guillaume

Hi,
Developing a generic tool won't take much time probably 6 hours at an experience level of 2+ years!!!
Once you develop you can use it for ever.
What all you need to do is create a field-symbol of type standard table. Get the table name and the file from the selection screen.
Create a dynamic internal table with reference to the table name entered in the selection screen. Upload the data and update the database.
Limitations in the design:
1. File should be in correct format and with the correct data. (Specific validations can't be done)
2. Table maintenance events can't be tackled.
eg: On entering the material number, Material description should automatically come.
Creating BDC for SM30 is ok. But this works only at a table level. We may not be able to make it generic as the screen field names changes based on table name.
So think and choose the right approach!!!
All the best:)
Thanks,
Vinod.

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.

Maintenance view of v/76

Hi gurus,
I have a couple of problems with maintenance view of the v/76. I have to make a z transaction of the v/76. I have made that. Here they want this description field of the view to be conditionally editable. Like if the level of the product hierarchy is within 3(less than three),then the description should not be changeable or the row should not be deletable.
How can this be done ?? There is another query too. I will post that separately.

This can be done in either of the two ways..
Use routines, on update or identify the development class and try to modify the screen under the development class.. by placing some conditions... usually for custom table maintenace it will not ask for access key.

Sairam

Use of Maintenance Views.

Hi all
I made a maintenance view for use in my programs to access data from different tables.
But facing problem while accessing data using a select query in program.
Like:-
REPORT ZVIEW.
data: it type table of zabhiview,
     wa type zabhiview.
select * from zabhiview into table it.
loop at it into wa.
write:/ wa-carrid,
         wa-ORT01,
         wa-CHANGEUSER.
endloop.
zabhiview-->maintenance view.
please tell how to use views in our programs.
Thank you.

for maintaining depending table entries with in a single view.
ex.
Let us take example three table emp_master, emp_sal and emp_rating. three tables are containing following fields
emp_master        emp_sal         emp_rating
empno               empno             empno
department        basic               status
fname                variable
lname                 pf
email                  tax
if you are creating maintanace view for the above three table. where you can maintain(create and change) value for the three table within a single view. Created and changed value in maintanace view will be saved in to the corresponding table.
Hope it will crear your doubt.
Regards,
Peranandam
