OS41: data modeler, how to use it?

Hi,
I'd like to know how to use T-code OS41: data modeler, when do I need to use it? and How to use? Please kindly help.
Thanks and Regards.

Hi Steve
<b>SD11-Data Modeler</b> is used, as its name implies, to model your processes.
You can create entity types, connect tables or views to those entities, implement connections between entities and if needed, you can also insert business objects all in a hierarchical way. You can connect data models to each other as well.
By this way, you document your own processes containing also some technical perspective.
Hope this small piece will give some basic understanding.

Data Modeler - how to access it

Howdy All,
I've heard of somethin' called the data modeller that I should have access to as a developer...
Does anyone know the transaction and how to use it?
Thanking you all kindly.

Data Modeler: How to prevent auto surrogate key in supertype/subtypes?

When forward engineering supertype/subtypes, how can I prevent the automatic creation of a surrogate key (propagated to all super/subs)? Data Modeler creates this SK only at the relational level. I have already defined a surrogate identifier in the logical; the intent is to engineer this to the relational model and propagate to each subtype.
Thanks,
Patrick

Thank you Philip for the explanation. I'd like to dig into this a little deeper, as I may be misinterpreting your explanation, and especially the last bit ( "...but foreign keys from subtype table to super-type table are not created" ).
My preferred super/subtype implementation consists of a supertype parent table (ideally with a [manually created] discriminator code value) and any number of subtype child tables, all referencing the parent (via FK column/RI). Note that RI is from the supertype/parent to each subtype/child table, not the other way round as Designer docs suggest (one of three different approaches: all-inclusive single-table, detail tables only, master/detail w/ RI from child to parent [arced]). The implementation I suggest ("the fourth way") allows the painless addition of a new subtype simply by creating a new child table and a new discriminator value for the parent. I've had consistent success using this approach with Designer for many years.
I've verified this successfully with a bare bones logical (3 levels), with appropriate UID on supertype/parent. All seems to transform well to relational model (i.e., all tables have inherited the parent PK, and individual attributes transformed to columns in the appropriate tables). The transform did not include a SurrogateID column.
However, the transform doesn't work quite so well in my full-blown Party model, even though I ensured that a UID was defined on the logical supertype/parent. also confirmed that Hierarchy relationships are defined between supertypes and subtypes. What else could I be doing wrong that causes the transform to create a SurrogateID column on each super/subtype table?
And on a similar note: are you suggesting that SQLDev Modeler transforms a supertype/subtype hierarchy with RI from detail tables to the parent table (i.e., backwards) when selecting "Table for each entity"? This approach would require a new FK column added to the parent table whenever a new subtype table was required.

Data Modeler - How to move relationship lines?

I can't figure out how to move the relationship lines on the data modeler.
Tried a bunch of things that have worked in all the other modelers I've used, but no luck. Couldn't find anything in the help text about it, either.

Hi Jim, David,
AutoRoute (on/off) can be managed at diagram level - use right mouse click on empty space.
In current published release (AutoRoute off) - straight lines (only two connection points) cannot be moved. You need intermediate points (at least one) for better arranging. Points (Elbows ) are created using Ctrl+mouse click.
Connection points also can be moved in next EA release.

SQL data modeller -- how to create 1 to 1 relationship foreign key ?

hi guys...
i got 2 tables..
table 1 - CFR
CFR_ID = primary key
table 2 - USER_PLAN
USER_ID = primary key
PLAN_ID,
CFR_ID = foreign key reference (table 1)
The business flows go like this..
insdie CFR table, it contain all records / transactions of a particular user/plan. everytime a new transaction occurs for a plan/user, a new CFR_ID / row will be generated.
after which, the newly generated CFR_ID for the new row , will be updated to the CFR_ID in USER_PLAN
Thus, there is always a 1 to 1 relationship between the 2 table regardless how many CFR_ID is generated for a particular USER_PLAN. as the CFR_ID in the USEr_plan table will always be the latest one generated inside the CFR table.
However, in the data modeller, i am unable to create such foreign key relationship... ANY idea how do i create a 1 on 1 foreign key relationship ? or there is no such way..
Thanks and Best Regards,
Noob

Hi philips,
Thanks for the wonderful reply..
Just to double comfirm with you,
even if i had set a unique constraint on CFR_ID(foreign key column), inside the relationship model, the relationship between the foreign key is still showing as a 1:m relationship right ?
just that a character 'U' will appear beside the CFR_ID column.
However the diagraphm is still showing a 1:M relationship.
is this correct ?

Noob

Data Modeling for controls using XML views(SAPUI5)

Hello ,
I am trying to create Table control using XML view and binding data to it through controller onInit method.
XML View Code is as follows :
<core:View xmlns="sap.m" xmlns:l="sap.ui.layout" xmlns:core="sap.ui.core">
    <l:VerticalLayout width="100%">
        <l:content>

            <Table id="idProductsTable" items="{
                path:'/businessData'
            }">
                <headerToolbar>
                    <Toolbar>
                        <Label text="Products"></Label>
                    </Toolbar>
                </headerToolbar>
                <columns>
                    <Column>
                        <Label text="Product" />
                    </Column>

                    <Column>
                        <Label text="Dimensions" />
                    </Column>
                </columns>
                <items>
                    <ColumnListItem>
                        <cells>
                            <ObjectIdentifier title="{COUNTRY}" text="{COUNTRY}" />
                        </cells>
                        <Text text="{REGION}"></Text>
                        <Text text="{CITY}"></Text>
                    </ColumnListItem>
                </items>
            </Table>
        </l:content>
    </l:VerticalLayout>
</core:View>
Controller onInit method Code is as follows :
var oData = {
            businessData : [ {
                'COUNTRY' : "Canada",
                'CITY' : "Toronto",
                'REGION' : "US",
                'LANGUAGE' : "English"
                'COUNTRY' : "China",
                'CITY' : "Bejeing",
                'REGION' : "Ashia",
                'LANGUAGE' : "Chinese"
        var demoJSONModel = new sap.ui.model.json.JSONModel();
        demoJSONModel.setData(oData);
        sap.ui.getCore().getElementById("idProductsTable").setModel(
                demoJSONModel);
Same thing when i tried with JS views , it worked however through XML view , I am getting empty table.
Is the data modeling correct for XML views?
Thanks,
Mahesh.

I've got it ! The reason for that is you bind items as below,
     <Table id="idProductsTable" items="{
                path:'/businessData'
            }">
This pattern is followed if you wanna add a formatter/sorter/grouping.
As you don't do any of those you can bind items as below & it doesn't require data-sap-ui-xx-bindingSyntax="complex".
<Table id="idProductsTable" items="{/businessData}">

Data Modeler - how can I define a foreign key but disabled

I am using SQL Developer Data Modeler Version 2.0.0 Build 570 on Mac OS X (Snow Leopard).
When defining a foreign key constraint, is there a way to define it as disabled?
When the DDL script is generated, the constraint is defined but it is always enabled, I want it to be disabled.
This is possible in the Jdeveloper data modeler, but I am missing the method to do this in SQL Developer Data Modeler.
Any help appreciated.

If you are generating the DDL edit the ENABLED keyword to DISABLED

Oracle Data Mining - How to use PREDICTION function with a regression model

I've been searching this site for Data Mining Q&A specifically related to prediction function and I wasn't able to find something useful on this topic. So I hope that posting it as a new thread will get useful answers for a beginner in oracle data mining.
So here is my issue with prediction function:
Given a table with 17 weeks of sales for a given product, I would like to do a forecast to predict the sales for the week 18th.
For that let's start preparing the necessary objects and data:
CREATE TABLE T_SALES
PURCHASE_WEEK DATE,
WEEK NUMBER,
SALES NUMBER
SET DEFINE OFF;
Insert into T_SALES
(PURCHASE_WEEK, WEEK, SALES)

There are a lot of linear regression models and approaches for sales forecast out on the market, however I will focus on what oracle 11g offers i.e. package SYS.DBMS_DATA_MINING to create a model using regression as mining function and then, once the model is created, to apply prediction function on the model.
Therefore I'll have to go through few steps:
i) normalization of data
CREATE OR REPLACE VIEW t_sales_norm AS
SELECT week,
sales,
(sales - 91423.95)/27238.3693126778 sales_norm
FROM t_sales;
whereas the numerical values are the mean and the standard deviation:
select avg(sales) from t_sales;
91423.95
select stddev(sales) from t_sales;
27238.3693126778
ii) auto-correlation. For the sake of simplicity, I will safely assume that there is no auto-correlation (no repetitive pattern in sales among the weeks). Therefore to define the lag data I will consider the whole set:
CREATE OR REPLACE VIEW t_sales_lag AS
SELECT a.*
FROM (SELECT week,
sales,
LAG(sales_norm, 1) OVER (ORDER BY week) L1,
LAG(sales_norm, 2) OVER (ORDER BY week) L2,
LAG(sales_norm, 3) OVER (ORDER BY week) L3,
LAG(sales_norm, 4) OVER (ORDER BY week) L4,
LAG(sales_norm, 5) OVER (ORDER BY week) L5,
LAG(sales_norm, 6) OVER (ORDER BY week) L6,
LAG(sales_norm, 7) OVER (ORDER BY week) L7,
LAG(sales_norm, 8) OVER (ORDER BY week) L8,
LAG(sales_norm, 9) OVER (ORDER BY week) L9,
LAG(sales_norm, 10) OVER (ORDER BY week) L10,
LAG(sales_norm, 11) OVER (ORDER BY week) L11,
LAG(sales_norm, 12) OVER (ORDER BY week) L12,
LAG(sales_norm, 13) OVER (ORDER BY week) L13,
LAG(sales_norm, 14) OVER (ORDER BY week) L14,
LAG(sales_norm, 15) OVER (ORDER BY week) L15,
LAG(sales_norm, 16) OVER (ORDER BY week) L16,
LAG(sales_norm, 17) OVER (ORDER BY week) L17
FROM t_sales_norm) a;
iii) choosing the training data. Again, I will choose the whole set of 17 weeks, as for this discussion in not relevant how big should be the set of training data.
CREATE OR REPLACE VIEW t_sales_train AS
SELECT week, sales,
L1, L2, L3, L4, L5, L6, L7, L8, L9, L10,
L11, L12, L13, L14, L15, L16, L17
FROM t_sales_lag a
WHERE week >= 1 AND week <= 17;
iv) build the model
-- exec SYS.DBMS_DATA_MINING.DROP_MODEL('t_SVM');
BEGIN
sys.DBMS_DATA_MINING.CREATE_MODEL( model_name => 't_SVM',
mining_function => dbms_data_mining.regression,
data_table_name => 't_sales_train',
case_id_column_name => 'week',
target_column_name => 'sales');
END;
v) finally, where I am confused is applying the prediction function against this model and making sense of the results.
On a search on Google I found 2 ways of applying this function to my case.
One way is the following:
SELECT week, sales,
PREDICTION(t_SVM USING
LAG(sales,1) OVER (ORDER BY week) as l1,
LAG(sales,2) OVER (ORDER BY week) as l2,
LAG(sales,3) OVER (ORDER BY week) as l3,
LAG(sales,4) OVER (ORDER BY week) as l4,
LAG(sales,5) OVER (ORDER BY week) as l5,
LAG(sales,6) OVER (ORDER BY week) as l6,
LAG(sales,7) OVER (ORDER BY week) as l7,
LAG(sales,8) OVER (ORDER BY week) as l8,
LAG(sales,9) OVER (ORDER BY week) as l9,
LAG(sales,10) OVER (ORDER BY week) as l10,
LAG(sales,11) OVER (ORDER BY week) as l11,
LAG(sales,12) OVER (ORDER BY week) as l12,
LAG(sales,13) OVER (ORDER BY week) as l13,
LAG(sales,14) OVER (ORDER BY week) as l14,
LAG(sales,15) OVER (ORDER BY week) as l15,
LAG(sales,16) OVER (ORDER BY week) as l16,
LAG(sales,17) OVER (ORDER BY week) as l17
) pred
FROM t_sales a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 104816.995823913
3, 77248, 104816.995823913
4, 106624, 104816.995823913
As you can see for the first row there is a value of 68861.084 and for the rest of 16 values is always one and the same 104816.995.
Question: where is my week 18 prediction ? or maybe I should say which one is it ?
Another way of using prediction even more confusing is against the lag table:
SELECT week, sales,
PREDICTION(t_svm USING a.*) pred
FROM t_sales_lag a;
WEEK, SALES, PREDICTION
1, 55488, 68861.084076412
2, 78336, 75512.3642096908
3, 77248, 85711.5003385927
4, 106624, 98160.5009687461
Each row out of 17, its own 'prediction' result.
Same question: which one is my week 18th prediction ?
Thank you very much for all help that you can provide on this matter.
It is as always highly appreciated.

Data Modeller: how to create and use collection type

Hello,
basically subj. I'm not clear how to ( for example ) create and use the data type based off the varray data type.
Please advise.
thank you
andrew

Hi Andrew,
you can create collection types (varray/table) in two ways:
1) in browser - find "Data Types">"Collection types" node use pop-up menu - it's just "create new collection type" there
2) in Data types model diagram - you can create collection of "certain structured type" or collection of references to it - use "new Collection ..." tool and first click on referred structured type and after that on structured type that will hold the collection - new attribute is added in latter type and if there is no such collection type already defined new collection type is created and you can edit it later.

Time and date function, how to use?

Hello everyone,
I want to know that how can we make use of these two system functions SY-TIMLO, SY-DATUM ?
What should i write in data? pbo? pai?
Should i write something like this in data?
DATA: Ok_date TYPE SY-DATUM.
DATA: Ok_time TYPE SY-TIMLO.
What should i write in pbo and pai and should i need to make changes in screen elements? do i need to create one?
Please guide and explain with an example. Thanks a lot for writing back.
Regards,
Lucky

Hi,
create two variables in the top include..
data :P_date type Sy-datum default sy-datum,
p_time type sy-uzeit default sy-uzeit.
Next go to screen and enter table syst...
and select datum and uzeit and drag to screen..
and rename the field to p_date for syst-date and p_time for syst-uzeit.

TDMS "data model" - how to evaluate?

We are using TDMS for quite some time now and I see certain data transfers which I do not understand:
Table SRRELROLES
That table is always transferred completely in our system (13 years of data, > 70.000.000 entries) even if I select to only transfer two months.
After having opened an OSS call (155066/2009) I was told, that selection criteria is as following:
( ( OBJTYPE = 'IDC0'
OR OBJTYPE = 'IDC1'
OR OBJTYPE = 'IDCB'
OR OBJTYPE = 'IDC4'
OR OBJTYPE = 'IDC9'
OR OBJTYPE = 'IDC8'
OR OBJTYPE = 'IDCA'
AND UTCTIME >= '20081001000000'
OR
( ( NOT OBJTYPE = 'IDC0'
AND NOT OBJTYPE = 'IDC1'
AND NOT OBJTYPE = 'IDCB'
AND NOT OBJTYPE = 'IDC4'
AND NOT OBJTYPE = 'IDC9'
AND NOT OBJTYPE = 'IDC8'
AND NOT OBJTYPE = 'IDCA'
If I do the select on our database:
SQL> select count(*) from SRRELROLES where
2 OBJTYPE = 'IDC0'
3 OR OBJTYPE = 'IDC1'
4 OR OBJTYPE = 'IDCB'
5 OR OBJTYPE = 'IDC4'
6 OR OBJTYPE = 'IDC9'
7 OR OBJTYPE = 'IDC8'
8 OR OBJTYPE = 'IDCA';
COUNT(*)
0
So the first term of the SQL will not read anything, the second after the OR will read all.
I don't understand that.
I have a few other BIG tables, that are also completely transferred (PPOIX, PPOPX, IDOCREL) and if any of the data of those tables is the base for other data, then it's understandable, that our target systems are MUCH too big.
Is there any method of finding out how the tables are "related" against each other and how the data is read?
Regards,
Markus

Hi Markus,
I don't know if you noticed, but SAP created note 1326118 to change the way that SRRELROLES is filtered. It might improve the results you get on your system, it did improve on mine.
By the way, that note changes the standard config by updating CNVMBTSELGRPVAL, so it will give you an insight on what are the standard filters (and how to manipulate them if needed). It's also true, though, that some filters are hard-coded in the selection programs.
Hope this help,

Data Modeler - How to add foreign keys to physical model?

I imported few tables from data dictionary and tried to generate a DDL file. The DDL didn't include foreign keys for some reason. Then I noticed that the foreign keys are in the relational model but not in the physical model. How do I get those foreign keys to the physical model?

That's the place where I'm looking for the foreign keys in physical model. I noticed that in relational model the Generate check box of a foreign key was unchecked. When I checked it, the key appeared in the physical model. But why is it unchekced sometimes? This has happened only few times, usually the foreign keys do appear in the physical model. If I do something special during import, I don't know what it is...

Data Merge: How to use script on the preview next a record and pre a record?

Preview data records too much, want to use the script implementation preview next a record and pre a record, and set shortcut keys for the script.
the following script can be opened and closed to preview:
app.menuActions.itemByID(108035).checked
But I don't know preview next a record and pre a record script in how to implement.

Bump. I'm looking for this shortcut as well. Any help would be very appreciated.

[FB4] PHP Data Service - how to use with DB2?

Hi,
I've tried to follow the tutorial that wires a datagrid to a PHP service. However I need to get data from DB2 rather than MySQL. I have created the service and populated an array using db2_fetch_object - the service works as I can call it with a simple test PHP script. However if I try to use this in the Data Service dialogs, when I get to the point of creating a return type for my getAllItems() call, it returns an error telling me to look in my server logs. My PHP logs say nothing.... Does this work with DB2? As far as I know the data returned by a db2_fetch_object is pretty close to the mysql version.
Thanks
NB my PHP code is as follows:
public function getAllItems() {
        $rows=Array();
        $query_cust = ".....SQL in here.............";
        $conn = connectLocal();
        if ($conn) {
            //error_log("Got connection");
            $stmt = db2_prepare($conn, $query_cust);
            $thisrow=0;
            db2_execute($stmt,array(0));
            while($row = db2_fetch_object($stmt)){
                $rows[$thisrow]=$row;
                //error_log($row->CUSTNUM);
                //error_log($rows[$thisrow]->CUSTNUM);
                $thisrow++;
            db2_close($conn);
        return $rows;

OK, if I remove the customer name field all works OK. So I tried reinstating the customer name field but modifying it in the returned array with a custom PHP function that replaces all the non-printing characters with acceptable ones. This function works ok when I create XML to use with Flex 3 datagrids, or with some javascript apps that use JSON arrays. But I still get the error. This is the function I use:
function stripcharsnotblanks($input){
$output = str_replace("&","+",$input);
$output = str_replace('"',"",$output);
$output = str_replace("²","+",$output);
$output = str_replace("ü","ue",$output);
$output = str_replace("ä","ae",$output);
$output = str_replace("ö","oe",$output);
$output = str_replace("Ö","Oe",$output);
$output = str_replace("\'","'",$output);
$output = str_replace("€","Eur",$output);
$output = str_replace("/","",$output);
$output = str_replace("%","pc",$output);
$output = str_replace(">","]",$output);
$output = str_replace("<","[",$output);
$output = str_replace("@"," at ",$output);
$output = str_replace(";",":",$output);
return $output;
Do you know of any other characters that could cause problems with AMF?
Thanks

What is data modeling how it is linked to BAPI?

Hi,
What is Datamodeling and how it is linked to BAPI?
Immediate reply is highly appriciable?
Regards,
Chow.

Datamodelling is much like all other modelling.
First you create a drawing of the original object. Then you buy some plywood or other suitable material for your model and cut this according to your drawings and scale. If you are rich and have the time you can create a 3D-model of your object and get laser-cut plastic or metal parts for your model.
When you have all your parts it is time to paint them. If you are lucky there is a shop specialising in everything for modellers, so they will have different kinds of paint in a good variety of colours.
Finally you assemble everything, and - hey - there's your model. Now, that wasn't too difficult, was it?
The answer to your second question is that datamodelling fits BAPI like a glove fits a fish. At least that is usually the case, but it depends...
