Logical dbase vs view

hi,
i know that logical database is a special ABAP/4 program which combines the contents of certain database tables.
i just 1 2 clarify if logical dbase cannot be used like transparent table or view in our customised report as logical database is a program and not a table.
right?

Hi,
Yes Logical database cannot be used as any other transperant table or a view. Since it is a program which uses predefined hirarchial structure to read the data from the TABLES that exist in the database.
Logical database is there to help you to read the data with out you coding for the data retrieval and which also takes care of all authority checks SO we have all that is required for this logically related tables at one central place.

Engineering from relational model to logical model duplicated views

Hi all,
Several times, also in different projects, when I engineer from relational model to the logical model, the comparator tool show me de differences.
In these differences there are no view differences, but when I finish the process everything goes right except that in the logical model under views, I see all the views duplicated with [view_name]v1.
I've tried not selecting the view checkbox, in the compare dialog,but I get duplicated views also.
I don't know fir sue if this happens with table also.
What can I do to solve this problem? Is this a bug?
Edited by: morfeo8marc on 04-abr-2012 2:02

The problem is fixed in DM 3.1.1.703 and it's published. You can run following script and save design in order to get mappings for views recovered.
Philip
lmodel = model.getDesign().getLogicalDesign();
rmodels = model.getDesign().getRelationalDesigns().toArray();
for (var i = 0; i < rmodels.length; i++) {
rm = rmodels;
eviews = lmodel.getEntityViewSet().toArray();
for (var k = 0; k < eviews.length; k++) {
ev = eviews[k];
tv = rm.getTableViewSet().getObjectByID(ev.getGeneratorID());
if(tv == null){
tv = rm.getTableViewSet().getObjectGeneratedBy(ev);
if(tv != null){
rm.getRMExtendedMap().createMapping(ev,tv);

Can you download a FormsCentral response as a pdf without having non-selected skip logic rules saved/viewed?

Hi,
Unfortunately, it is not possible to convert the response to pdf without the non-selected fields.
As a workaround, you can hide a particular column and then convert the response to pdf.

Changes and Logical Delete in View Maintenance

Hi everybody.
I've defined a table view maintenance V_TABLE for T_TABLE, with five fields. One of them is defined as 'R' (not editable field).
I defined an event 05 and an event 02 (for create and save) where I move SY-DATUM to the CREATED_DATE or UPDATE_DATE fields depending on it is a new record or a modification.
But if I modify several records only one is updated.
Besides, if the action is "delete" in the view maintenance, it must be a logical delete and move an 'X' to one of the editable fields.
Can you help me please ?
I can't see the action for each record in global tables.
Event f_save ( 02 )
IF t_table-created_date IS INITIAL.
    t_table-created_date = sy-datum.
ELSE.
    t_table-last_upd_date = sy-datum.
ENDIF.
MODIFY t_table.
Event f_new_entry ( 05 )
t_table-created_date = sy-datum.
Thanks in advance,
Liliana.

Hello Karol, thank you for your answer.

Logic Control & "Global View"

Hi,
When switching Global View on a Logic Control unit, say from Audio Tracks to Audio Instruments, the LCD always jumps to the highest instrument or track available. For example, I might be using 8 of 24 available audio tracks and five of 64 available audio instruments. When I switch views the LCD will show either instrument 64 on the left, or audio track 24. I then must either select an instrument via mouse on the arrange page or scroll back via the bank buttons on the LC to have, say, audio instrument 1 visible. Why? Any fix out there?
Along the same line, an improvement in the Logic Control interface would be intelligent switching between views on the LCD. For example, if an audio track is selected via mouse on the arrange page, the LC view would jump to that "type" of view even if the global view selected (on the LC) was "Outputs" or "Midi Tracks".
Cheers,
RW

On my system (with Logic Control) each Global page remembers where it last was. If I was looking at busses 9-16 last time I was on the Global bus mode, that is where I return to next time I engage busses in Global mode.
I like the fact that the LC does not switch to another object type when in Global mode. I use this to use the faders for busses while looking at tracks.
I do wish that tracks which are hidden in the arrange (and track mixer) would also be hidden on the LC when not in Global mode. This would allow global mode to show any object regardless of hidden state or use in the Arrange, and Global off to reflect the track status of the Arrange page.

Help with using dynamic sql logic in a view please?

Greetings,
I want to create a dynamic union using all the databases on server. The following works:
declare @sqlvarchar(max)
select
@sql=IsNull(@sql+'union
all ','')+'select
* from '+name+'.[dbo].[A]''
inner join '+name+'.[dbo].[B]'' on
a.f1=b.f1'
from
sys.databases
where
name
in(select
name
from
sys.databases)
exec
(@sql)
The problem is I need something tangible, like a view, to query using SSAS later. I've tried to use SELECT into to load a new table with a resulting dataset. It gives me a syntax error - the dynamic part can't be combined with static. I can't use OPENQUERY
because it all happens on the same server. Assistance would be appreciated. Thanks

Well, you could regenerate the view each time a database is created or dropped.
Or you can define your cube using an empty view and load the cube using SSIS, eg with
Dimension Processing Destination.
Or you can use something like a CLR TVF inside your view.

Logical Dbase Performance

hi fellow programmers..
i developed a payroll program which work fine at the development server..
upon transport to QAS server..i noticed that the program is not performing well when dealing with large number of data..
i also tried running it with minimal data(2K records) at qas server and works fine since i applied most of the performance tunning guide...
is there any way to prevent this?when i debug it i found out that for 1-3k records the program is doing well, but upon reaching 4k records above, the program is running slow.
my plan is to divide the data by 2k so that from start of execution to finish, the program will run fast...
any other approach?or any suggestions?
thanks for reading..

Hi,
PY extraction data is long lasting process. If you run it for so huge population it will extend even more. I usually don't bother how long it will take (someone else will run it anyway;) ). Normally user can provide not the population itself but PY area or personal area instead (so the report would run couple times but faster).
What is to be noticed here is that you may reach timeout as run time will be too long. I suggest to use FM SAPGUI_PROGRESS_INDICATOR in order to avoid such situation.

Logic to get the view in MM02

Hi,
I would just like to ask if there is an easier way to get the selection views in MM02. There are different views per material and I need to insert the logic in getting the view to a custom program. The custom program will be used for performing a BDC transaction that's why I need to get the logic for the views.

Hi
Try using the function module SELECTION_VIEWS_FIND
* Material views ....................................................
data: l_vpsta like t130m-pstat.
select single vpsta
         into   l_vpsta
         from   mara
         where matnr = p_matnr.
* Get View sequence .................................................
data: l_bild like t133a-bilds,
        lt_bild like mbildtab occurs 0 with header line.
* Screen Sequence for Standard Industry tab pages in material master
l_bild = '21'.
* Get screen sequence
call function 'SELECTION_VIEWS_FIND'
    exporting
      bildsequenz     = l_bild
      pflegestatus    = l_vpsta
    tables
      bildtab         = lt_bild
    exceptions
      call_wrong      = 1
      empty_selection = 2
      others          = 3.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

How to wrap a view in oracle

Does any one know how to wrap a view in Oracle, I know it is not possible, yet. Are there any third party software to wrap the logic in the view.
Thanks,
Sanjay

Your best bet is to write a view that queries the source tables and contains any necessary business logic
CREATE VIEW VBASE AS SELECT A.COLUMN_A FROM TABLE_1 A, TABLE_2 B, TABLE_3 C WHERE A.ID = B.ID AND B.ID = C.ID;
create a view for exposure to the user that queries the base view.
CREATE VIEW VSECURE AS SELECT COLUMN_B FROM VBASE;
and grant privileges to VSECURE.
GRANT SELECT ON VSECURE TO SECURE_USER;
This will allow the user to see, query, and describe VSECURE without seeing the definition for VBASE.
The advantage of the this approach is that the query engine can still push predicates down into the base view to optimize the performance or the query where as this is limited with the pipeline function and can become a tuning headache.
eg.
SQL> -----------------------------------------
SQL> -- create some tables

Logical databse

hi all
i had tried so many times to change the selection screen of logical database but i was not able to do this whenever i change the screen that change is disappeard on runtime can anyone help me on how to change the selection screen of logical databse.
sunanda

You can define a selection view from the ABAP
Workbench by choosing Extras ® Selection views to open the
Logical Database Builder, or by choosing Further objects
from the initial screen of the Repository Browser. They
are identified using a three-character key describing the
origin of the selection view. Predefined selection views
have the key SAP, customer-defined ones have the key CUS.
This way, users can define the best logical database
selection views for their requirements.
If you want to use a selection view in a logical database,
it must be called STANDARD, and must be assigned to a
logical database. Selection views that are not assigned to
a particular logical database may have any name, and they
can be used freely.

Snowflake dimension: named query vs. database view

A test question features a Product table with a Product Size code; Product Size description is taken from ProductSize table. As far as I can tell, the question asks me to choose between (a) setting up a database view joining Product and ProductSize, and
(b) doing the join in a data-source-view named query. I don't see a clear winner. (My thinking is as follows. Yes, he view would speed up the processing, even if not materialized. On the other hand, with a small dataset, the performance gain would be
minor in absolute terms. Do I want to have an extra database object in the picture?) Yet the question's author does. Can anyone advise please?

Hi Demyan,
According to your description, you want to know which is better, using named query in datasource view or using database view, right?
Based on my research, there is no performance differences between using named query in datasource view and using database view because they both result in SQL query being sent to the source system. Here is a blog which discuss this issue.
Consistency: If you already have logic in database views, I would continue to use them. As long as you know that you go to one spot to view/change the logic. Putting the logic in 2 different spots could lead to confusion.
Security Permissions: often you may not have permission to alter the source databases, in this case you have no choice but to setup named queries in the dsv.

Solution:
The steps in detail as follows:
Download the jQuery API and upload the js file into the
SiteAssets Document Library.
Save the following code as a js file (showAttachments.js) and upload it into the
SiteAssets Document Library.
(function () {
// Create object that have the context information about the field that we want to change it output render
var attachmentsFiledContext = {};
attachmentsFiledContext.Templates = {};
attachmentsFiledContext.Templates.Fields = {
"Attachments": { "View": AttachmentsFiledTemplate }
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(attachmentsFiledContext);
// This function provides the rendering logic for list view
function AttachmentsFiledTemplate(ctx) {
var itemId = ctx.CurrentItem.ID;
var listName = ctx.ListTitle;
return getAttachments(listName, itemId);
//get attachments field properties
function getAttachments(listName,itemId) {
var url = _spPageContextInfo.webAbsoluteUrl;
var requestUri = url + "/_api/web/lists/getbytitle('" + listName + "')/items(" + itemId + ")/AttachmentFiles";
var str = "";
// execute AJAX request
$.ajax({
url: requestUri,
type: "GET",
headers: { "ACCEPT": "application/json;odata=verbose" },
async: false,
success: function (data) {
for (var i = 0; i < data.d.results.length; i++) {
str += "<a href='" + data.d.results[i].ServerRelativeUrl + "'>" + data.d.results[i].FileName + "</a>";
if (i != data.d.results.length - 1) {
str += "<br/>";
error: function (err) {
//alert(err);
return str;
3. Edit the list view page.
4.
Edit the list web part. Go to Miscellaneous -> JS Link.
5. Add the following URL into the JS Link textbox.

Hi,
Thanks for your details steps, with your steps I can reproduce the issue using SharePoint server 2013 without any CU or PU.
The items not displayed when group by the calculated column.
However, I had done more research and test, I had found that it’s a known issue.
I had tested with the SharePoint server 2013 which applied the December CU, the issue disappeared, the items displayed well.
You can install the December CU for SharePoint server 2013, then test whether it works.

Adding up entries of 2 different columns of a table in a single view column

Hi All,
I have a requirement wherein I have to add up the entries of 2 different columns of 2 different database tables and show it in one column of a View.
Eg. Table A has column A and Table B has column B. I create a view C with column C.
Now Col C = Col A + Col B
Can anyone please let me know how this view can be created?
Thanks,
Momdipa

Hi Momdipa,
ABAP Table View does not support dynamic arithmetic operations. So, you can't achieve this business logic in the view. There are no operators in the view which can help you to do this.
If you need this functionality, you need to create a ABAP Report to calculate the sum on the execution of the Report. And then you can update the View based on your own business logic.
Hope this helps.
Thanks,
Samantak.

How to SELECT ALL records of a TABLE VIEW in the BSP page

Hi All,
In the BSP portal, I am displaying some data(multple records) in the form of a table using the BSP TAG <htmlb:tableView>. I wrote the logic in the 'VIEW' of the BSP application which will be triggered by the controller. I have used the attribute selectionMode = "MULTISELECT" to have a Check Box to select a row.
My requirement is to have a button/checkbox on the first column of the header of the table view. By clicking on this, it should select/desect all the records of the table. Could someone please help me how to do this? What attribute I should use in the tableview to get the button in the header row of the table and how to select all the records of the table.?
Please provide your valuable inputs.
Thanks & Regards,
Paddu.
