How to create tables and relationship between ?

Hello everybody,<o:p></o:p>
I have three table with structures as follow:<o:p></o:p>
<o:p> </o:p>
Table1
contains information on ledger accounts,and
Table2 contains Groups of the detailed
accounts.
When defining ledger
accounts , we must associated them with
groups of detailed accountsthat
are
set
by the
Check
boxes. groups of detailed accounts are three
levels, At each level, there are fifteen
groups as follow:
1_others ,2_People ,3_companies ,4_
Cost centers ,5_projects ,6_
Letter of Credits ,7_ Current
Accounts ,8_
Banking facilities ,9_
Commodity ,10_ Branches
aggregation ,11_ Purchase
Contract
Services ,12_
Sales Contract
Services ,13_
Export Products ,14_
Control account ,15_
Months.Table3 contains detailed accounts information that should associated with groups of detailed accounts(fifiteen groups).
In addition, we
have in our program four combobox,
detailed accounts must be
linked to the detailed groups
so that, by selecting one ledger account in combobox1 it should display detailed accounts of level1 in combobox2 ,detailed accounts of level2
in combobox3 and detailed accounts of level3 in combobox4.<o:p></o:p>
<o:p> </o:p>
How
to design tables and the relationships between them, so
with select the ledger account I can see the detailed
accounts of per level in other comboboxes?<o:p></o:p>
<o:p> </o:p>
I've
spent
a lot of time
on this
subject
but
I have
not been able
to
solve this problem.<o:p></o:p>
Please help me,<o:p></o:p>
Best regards.<o:p></o:p>

I am guessing....I hope it is helpful...

Data model - is tables and relationships between them are graph or tree

Hello
I want to ask if tables in database are nodes of graph what should this graph looks like - like real graph (with
cycles) or tree ?
Let the tables are nodes of graph and the relationships between the tables are edges in the graph.

You can put the \ tag before and after text to preserve white space. That likely makes things easier to read if you're trying to post ASCII graphs.
I wouldn't hesitate to use the proper set of tables and relationships for the entities I was trying to model. Would I be concerned if my data model were full of loops? Sure, that might cause me to double-check that I hadn't done something silly. Would I be concerned if my data model had a loop if that was the best way to model something? Not at all.
There is no theoretical answer because the quality of a data model has nothing to do with whether it is more tree-like or more graph-like.

How to create table and digital signature ?

Hello,
I would like to ask two questions regarding SAP interactive forms by adobe.
1st question:
How to create table in interactive form?
Table that i can add rows and column and will show it in the form.
Example the rows and columns that i want:
ID: Name: DOB:
1 Jack 01/02/80
2 Ivy 10/12/82
2nd question:
How to create digital signature ?
I'm creating a adobe forms which need employee to sign on the form. I use signature field at my form. However, i don't know how to create a new signature and insert in the signature field.
Can any one provide the answer with step by step guide?
Thanks a lot

Hi Pradeepa,
you said you have your digital signature in
BMP format? That means Bitmap and would mean you are actually talking about a picture! THIS IS NOT A DIGITAL SIGNATURE!
A digital signature is a cryptographic key (aka public key cryptography) that is used to digitally sign a document, or at least a hash value derived from the document. Digitally signing means, applying the key in a well defined way (this is the algorithm used) to the document or hash value. You do this with your private key and the receiver of the document can then use your public key (which you can distribute in any way you want, even unsecure) to unencrypt the hash value. If this succeeds the receiver knows that the document was signed by you.
This is because both keys are mathematically related in such a way, that what one key encrypted can only be decrypted by the corresponding other key and by no other key. You even can´t decrypt a document with the same key it was encrypted with, this is the difference to symmetric encryption - please have a look at help.sap.com and search for digital signatures.
The named formats (afs, pfx and p12) are ways of coding the key, together with information about your person, such as email address and information about validity of the key into a
certificate. This type of certificate is then called a x.509 certificate and is the same you might have seen when connecting to a secure webserver such as the one of your bank website.
Signing a form with such a certificate provides for mathematically and therefore business related proove of a users identity.
In case you are really using a bitmap, this cannot work and would not serve you any good.
Ask yourself this question: I want to make sure that the form was signed by a specific person. How can I make sure that the signing can only be done by the person pretending to have done so?
A bitmap contains a picture, probably of the persons handwritten signature. How can I make sure that this picture was NOT recreated in MS Paint or Photoshop by someone else?
The answer is:
you can't! Therefore this way of prooving identity is useless.
You need to provide your users with digital signatures, put these in the certificate cache of your IE. If a user then clicks on the signing field, the private key is used to digitally sign the form - create a hash value of the form and encrypt it with the private key. After the form is send back to the server or you, you use the corresponding public key to decrypt the hash value and, as said above, if this succeeds, identity of the signer is proven.
THIS IS AN OVERSIMPLIFICATION! You might want to take a look at Adobe Reader Credentials.

How to create tables and views and procedures in other users as one

HI to all,
I am having a user named vijay and i am trying to create the tables in user srini as user vijay
in user vijay i'm having tables
1. company
2. department
i wrote one procedure
create or replace procedure sp_createobjects{short_name in varchar2}
{my openbracket key is not working so that i put open braces here}
as
cursor table_name is select object_name from dba_tables where object_type = 'TABLE';
var_table_name varchar2{1000};
begin
open table_name;
loop
fetch table_name into var_table_name;
execute immediate 'create table ' || short_name || '.' || var_table_name || ' as select * from '||var_table_name;
end loop;
end;
the procedure is created sucessfully. but when i am trying to execute the procedure it is throwing the error as insufficient privileges.
my 2nd question is how to create the procedures into the other user?
Thanks in advance

First of all, your query "from dba_tables where object_type = 'TABLE'" returns all tables, not just the tables of the user vijay.
So there are two possibilities, you may be getting the error because you cannot select from another user's table or you may be getting the error because you cannot create a table under the user srini. To create tables in another schema you need the "create any table" privilege.

How to create Tables and Fields in Java DI API?

I have the problem to get the handle for IUserTabledMD.
userTablesMD = (IUserTablesMD) getCompany().getBusinessObject(SBOCOMConstants.BoObjectTypes_oUserTables);
does not work as in VB (getCompany() gets the ICompany handle).
and
userTablesMD = SBOCOMUtil.getUserTablesMD(getCompany(),"");
needs an additional String!?!?!?!?
How to get the handle to create new user defined tables?
I think Fields needs the same methods.

Depicting tables and relationships

Hi all. I need a tool that can display the tables and relationships between the tables of an Oracle Database in a specific way. Let me explain.
Prehistory
We have an Oracle Database :-). It has a lot of tables, many foreign keys etc. The relationships between the tables are quite intricate.
Purpose
The purpose of this is to create a "scheme" of the data (the tables and relationships we have) which is simple to understand. We are going to use this scheme to help new employees understand the data structure. I tried to create such a scheme with the help of Oracle Designer but I found Server Model diagrams and ERD diagrams not satisfactory.
Data scheme description
I want the scheme to display tables like in a server model diagram. But there is one major problem I encountered with server model diagrams. The server model diagram shows everything: column names, column data types, relationships. But there is one thing it does not show (or I couldn't find how to make it show it). I want the diagram to show comments for columns together with the column names (for example in square brackets after the column name). It is obvious that the column name usually does not tell much about what the column contans. It is only comments or descriptions that usually contain a lot of information about the column's contents. And I want comments to be shown on the diagram because I think this will be the simplest way for the new employee to get used to the data structure, understand it and get involved with real projects faster. I.e. make the new employee's "learning curve" much shorter :-). And I want descriptions (comments are short, they can be shown on the table, descriptions are long, they cannot be shown) to be easy to access on the diagram. For example "Right click -> description menu item". Actually the tool I'm looking for should be able to customize the view of the diagram, show and hide some elements (for example show comments, hide types etc). View customization capabilities are what I'm looking for. I think Oracle Designer lacks these capabilities.
Server model diagram disadvantages
The server model allows to add comments for columns but it cannot display them(comments) on the diagram. Comments are really difficult to access in the server model diagram. One can access only one comment for the column at a time.
ERD diagram disadvantages
I checked out ERD diagram as well. It is a little better at accessing comments. The properties of the table(tab "Attributes") shows column names and comments in one table. It is much more convenient for the new employee. But in the retrofit process (creating ERD diagrams from existing database tables) Oracle Designer deletes all "ID" fields. It places relationship links on the diagram instead of these attributes. In this case I'll have to create these fields manually in order to "reproduce" the exact structure of the database. It is very tedious when we have a hundred tables.
Question
Is there a tool that can create the diagram I want from existing tables (not from the scratch)? Or the server model diagram is my best bet? One more thing. I don't need a tool that can only draw diagrams even in the way I want. I need a tool that can create a diagram from existing tables and after this allow me to customize the view of the diagram, add comments, descriptions, show and hide comments, data types for columns etc. Perhaps there is a way to achieve this goal by means of Oracle Designer?
Additional Info
Database - Oracle 8i
Oracle Designer - Oracle Designer 9i.
Thank you in advance.

Alexandre, could you please provide more details on how you work with PowerAMC? Does this tool has powerful capabilities in reverse engineering? And does it allow the user to customize the view of the diagram as I described? I found only some documents in French regarding PowerAMC but on the Sybase site I found that PowerAMC was "also sold as PowerDesigner". I found this link
http://www.sybase.com/detail?id=1040802.
Do you have any documents that describe the reverse engineering capabilities of PowerAMC or manuals? (documents in English of course). It would be very kind of you if you found such documents.
Unfortunately I couldn't find enough info on the official site.

How to create Parent and Children is a tree table / trigger sequence number

How to create Parent and Children is a tree table when the primary key of the parent is generated via a trigger and a sequence number in the database?
My problem is when I create a parent and then right away a children. The parent still not have a primary key until the transaction get to the database. I get a error when trying the create the children, cannot insert null in the foreign key field of the children.
Please help.
Stephane

You should have the parent key be marked as a DBSequence type.
Then you should have the association between the master and detail defined as composite association to make sure that the posting order to the database is correct.

Hi,
can any one guide me how to create table maintanence generator and after creating,enduser must use using ztcode.
any help can be appreciated.
Thanks & Regards,

Hi,
Table Maintenance generator is required to do Manual entries in the Table. If the requirement is to update the table only programmatically and not manually then table maint. generator is not required.
Manual entries in table can be maintained ( New record can be inserted / existing can be modified ) using transaction SM 30, if the table maintenance for the table is generated.
How to activate Table maint.
Goto SE11 and open the table.
Click UTILITIES -> Table Maint. Generator, Enter the details and click on Save. Then activate the table.
chk a sample 1.

Sap script '' how to create table frame in sap script"""

i have some problem in sap script'' how to create table frame in sap script"""

Hi,
you can use BOX command..
Syntax
/: BOX [XPOS] [YPOS] [WIDTH] [HEIGHT] [FRAME] [INTENSITY]
Effect: draws a box of the specified size at the specified position.
Parameters: For each of XPOS, YPOS, WIDTH, HEIGHT and FRAME both a measurement and a unit of measurement must be specified. The INTENSITY parameter should be specified as a percentage between 0 and 100.
1. XPOS, YPOS: Upper left corner of the box, relative to the values of the POSITION command.
Default: Values specified in the POSITION command.
The following calculation is performed internally to determine the absolute output position of a box on the page:
X(abs) = XORIGIN + XPOS
Y(abs) = YORIGIN + YPOS
2. WIDTH: Width of the box. Default: WIDTH value of the SIZE command.
3. HEIGHT: Height of the box. Default: HEIGHT value of the SIZE command.
4. FRAME: Thickness of frame.
Default: 0 (no frame).
5. INTENSITY: Grayscale of box contents as % .
Default: 100 (full black)
Measurements: Decimal numbers must be specified as literal values (like ABAP numeric constants) by being enclosed in inverted commas. The period should be used as the decimal point character. See also the examples listed below.
Units of measurement: The following units of measurement may be used:
TW (twip)
PT (point)
IN (inch)
MM (millimeter)
CM (centimeter)
LN (line)
CH (character).
The following conversion factors apply:
1 TW = 1/20 PT
1 PT = 1/72 IN
1 IN = 2.54 CM
1 CM = 10 MM
1 CH = height of a character relative to the CPI specification in the layout set header
1 LN = height of a line relative to the LPI specification in the layout set header
/: BOX FRAME 10 TW
Draws a frame around the current window with a frame thickness of 10 TW (= 0.5 PT).
/: BOX INTENSITY 10
Fills the window background with shadowing having a gray scale of 10 %.
/: BOX HEIGHT 0 TW FRAME 10 TW
Draws a horizontal line across the complete top edge of the window.
/: BOX WIDTH 0 TW FRAME 10 TW
Draws a vertical line along the complete height of the left hand edge of the window.
/: BOX WIDTH '17.5' CM HEIGHT 1 CM FRAME 10 TW INTENSITY 15
/: BOX WIDTH '17.5' CM HEIGHT '13.5' CM FRAME 10 TW
/: BOX XPOS '10.0' CM WIDTH 0 TW HEIGHT '13.5' CM FRAME 10 TW
/: BOX XPOS '13.5' CM WIDTH 0 TW HEIGHT '13.5' CM FRAME 10 TW
