Doubt about Master-Child relationships.

Hello,
I've a doubt about master-child relationships.
Any row in the master table need to has at least one row in the child table. What do I guarantee that?
Please, any ideas.
Thnx.

If im correct you are asking that any row in master table should have a corresponding child record in detail
(transaction) table.
WELL , There is no compulsion that the child table should have a record linking to record in master table.
Master table is not depended on child table. Child table is dependent on data reference on master table.
Pls note that Master table is independent of the child table ( in terms of data reference only) .
This doesnt mean that if you want to delete the master records when child records exists. it gives an error in that case.
check the following example
SQL> create table master(n number primary key);
Table created.
SQL> insert into master values(1);
1 row created.
SQL> create table child(t number references master(n));
Table created.

Forms Builder Master Child relationship --- column datas gets hided.

Hi All,
I have a screen which have 5 columns. Out of which first 3 columns belong to Table A and 4th column belong to say Table B and the 5th column belong to Table C. There is a master Child relationship between Table A and Table B also between Table A and Table C.
The issue is, i enter the data for these columns in row wise. I enter all 5 columns with value and when i switch to next row, the 4th and 5th column's value gets hided.
Please suggest.
Thanks and Regards,

You have relation with
Table A with Table B
Table A with Table Cwhen you switch a record to another record at bloc/table A, it's normal forms behavior it's will hide value of block/table B and C. when your click on associate row of block/table A it will show.
It's the form normal behavior for relationship.Hope you understand.

Maintaining Master-Child relationship during ODI transformation

ODI Gurus
For following requirement, we need the best approach to transform data from Source to Target instance(Both Source and Target instances are running on Oracle Database)
Tables in Source Instance
a) Source_Master
b) Source_Detail (One to many relationship with Source_Master)
Tables in Target Instance
a) Target_Master
b) Target_Detail (One to many relationship with Target_Master)
In ODI need to create interfaces to transform data from
a) SOUCE_MASTER table to TARGET_MASTER table and
b) SOUCE_DETAIL table to TARGET_DETAIL table
NOTE: Value for Primary Key column in Target Instance tables Target_Master and Target_Detail are generated from Database Sequence.
Once the transformation is completed using ODI, the master-child relationship should be maintained in Target Instance between Target_Master and Target_Detail table. How do we achieve this in ODI ?
Thanks
Uma Shankar

For this, create the first interface for MASTER, in the mapping for the primary key you should map the database sequence, something like: MYSCHEMA.MYSEQUENCE_NEXTVAL.
Create the second interface for DETAIL, and on the sources pane of the interface, drag the SOURCE_DETAIL and TARGET_MASTER datastores. Make the joing between the two using the keys from the source. In the Primary key mapping of the DETAIL_TARGET make sure you select the new PRIMARY KEY of the TARGET_MASTER, mapping in staging area. This "lookup" will be done in the target data server.
If you are going to be doing updates and inserts in the target, you should make sure you set the Update Key selected for each of the targets to the same keys as on the source (obviously you won't have the target values!)
If you are not going to do any updates, then use the IKM SQL Control Append rather than the incremental update IKM.
You can optionally set the COMMIT option of the first interface to NO, and only commit on completion on the second interface if you want to ensure the full 'all or nothing' transactionality - but bear in mind, large volumes of uncommitted changes use resources....

DOUBT ABOUT MASTER DATA

Hey guys!!!
I have a doubt about master data, i need to add an atribute to a master data characteristic, do i have to erase the data to do this or can i add the atribute without erase the data?
Thanks and Regards!!

KK,
Thats not true.
You neednot delete master data to add attributes to a characteristic.
Additionally, you cannot delete (there are methods to delete which are not suggested) master data in normal way, if there is transactional data for that characteristic.
Luis,
You should be able to add attribute to a characteristic without deleting master data, but make sure you load data for the same for values to reflect.

Doubt about EntityBean childs

Hi,
If I have 2 EntityBeans:
Customer
  id
  name
CustomerPhone
  id
  customer_id
  phone
In the "Customer" EntityBean i know that I should have a method "getPhones", but what should be the its returning class?? A Collection? A Vector? Whats the diference?
And what i should put on the collection?
Is it something like the code above? (is it gonna work?)
.... SELECT id FROM CustomerPhone ...
while (rs.next()) {
    collection.add( home.findByPrimaryKey( CustomerPhone.id ) );
}Thanx in advance,
feu

Hi there,
If you are using ejb 1.1 then in the Customer PhoneEntity bean crreate a finder method findByCustomerID() and use this in the getPhones() method of the Customer Entity Bean. Thiis method will return a collection of remote references to matching entries.
In ejb 2.0 you can (possibly) use CMP and set up a Container Managed Relationship between Customer and Customer Phone.
Hope this helps

Issue with Master and child relationship,viewlink

Hi Frnds,
In one of our custom pages we have Master child relationship between Invoice lines and their distributions.
Things work absolutely fine when total no of distributions(say 10) are equal to max no of distributions that can be shown on 1st page(i.e equal to advancetable property value 'Records displayed'..say set as 10)
What happens is when in advance table I click on next button to navigate to next set of records and then edit some field that have any event..ppr or lov my control by default gets transferred to very first set of records.
!!!!!!!!!!!!!! Also this happens only when no of invoice lines are more than 1.
I not sure whether the issue is with VL,VO,AO or the advance table property.
One simple solution that I have tried is...getting back the focus to the row that is updated but it causes some other problem.
Any pointers will be very helpful
Thanks in advance.

Hi any help???

Master-detail relationship - passing parameter from form to form

Hello.
I have a question about master detail relationship.
In first form we have master-detail relationship.
Example on dept, emp tables:
We query dept (master), so we can get one or many emp (detail) records. Then we have a third table - tasks. Tasks table (detail) can have many records for one employee.
Tasks table is in another form, which is called with call_form built_in. So we pass a parameter from master to detail - parameter empno. Because of that, we can only see tasks for one employee and can't navigate to another employee. This is normal.
Now comes the question.
Is it possible to call a form (with tasks table) with deptno parameter (so we can navigate through all employees with that department), but first show employee that was last used in first form?
Example of our goal.
Master: deptno = 20
Detail: navigate to JONES employee
Call new form (tasks)
Tasks for JONES employee are first shown
Can navigate to another employee - without requery
Is this possible?
If we pass deptno parameter, we can navigate through all employees - but must navigate to the employee we last used in first form.
If we pass empno parameter to second form, we see last used employee but cannot navigate to another employee without requery.
Hope you understand my problem.
Thanks.

Hi
yes you can pass parameter from one form to another.
In your master detail form set the trigger when-new-instance and there define the global variable like
:GLOBAL.G_CIRCLE_ID := NULL;
and in your task table set the trigger when-new-instance and there define the global variable like and also write this code
:GLOBAL.G_DIVISION_ID := NULL;
IF :GLOBAL.G_CIRCLE_ID IS NOT NULL THEN
     GO_BLOCK('DIVISION');
     SET_BLOCK_PROPERTY('DIVISION',DEFAULT_WHERE,'CIRCLE_ID ='||''''||:GLOBAL.G_CIRCLE_ID||'''');
     EXECUTE_QUERY;
END IF;
:GLOBAL.G_CIRCLE_ID := NULL;
now you maintain your trigger according your need.

Master Detail - Detail parent child relationship

Hello All,
I have a setup where I have 3 tables. Call them A, B, and C. Table A is the parent table to the child table B. Also table B is the parent table to the Child table C. Is there a way to represent this in Apex? So far I have created two Master Detail forms: Master Detail form one has the relationship A+B and Master Detail form two has the relationship B+C. Can Apex support a Master Detail Detail form.
Also, is there a way to have my detail page editable without linking to another page to save and update?
Please let me know what everyone thinks.
Thanks
Ryan

Hi,
You can google it - so much information is available online. Any how
Parent Child relationship
PK FKBasic example - Parent and Child in real life -similarly the Table_A is having relation with some other Table_B.
Example
Table_A
columns :-
Student_No, Student Name, Student_address
Now the Table_B store the assignment details
Student_No, Subject_1,subject_2, subject_3
Now relation of join is Table_A.Student_No = Table_B.Student_No
With out the TAble_A details -can be identified the Sudent details etc., No - It's Master data - which is not dependent on any other table and Column Student_No- Acts Primary Key which is Unique -through which we can identify a specific details of particular student. Now comes to Table_B - with out the student_No - we can't say whose details of assignments belongs to whom - now the student_No in Table_B is dependent on some other table - now this table acts a child and Primary Key of Table_A acts Foreign Key - that column helps to identify the record.
Master Detail
Reference tablesconcept of understanding is same when - when comes c,c++, java and c sharp - acts the same but inheritance, interfaces, polymorphisms and overloading code of language differs. If you go further j2ee differs

Customer Master -- Parent + Child Relationship

Hi
I have an requirement from user asking me to set Parent -Child relationship for a customer.
Correct me if i am wrong.
I have customer numbers 1000 and 2000.
In "payment transactions" tab , i have included 2000 in "Alternat. Payer" field. So now 2000 will be the alternative payer for 1000 customer.
I want to see this relationship in FBL5N. In what way should i ensure that the functionality is maintained.
Please let me know
Thanks
Rajanikanth.

Please note I do not respond direct through e mail, only on this forum.
If the customer has not been set up correctly there will not be any entries in the branch field.
As mentioned you need to have the parent customer number set as the "payer " partner function in the child's customer account number.
This will mean you are selling to the chil, but the parent is paying, and this is where the invoice will go to.
If you have not set the master data up like this, then there will not be any values there for you.
Please award points if this is helpful and has been helpful so far.

Question about File Content Conversion and parent-child relationships...

Hello!
     I have read probably every blog, article and SAP Help document on the topic, but I am stuck on this one. I am trying to convert a General Ledger flat file to an IDoc using the classic file --> IDoc scenario. The setup is done and working, but the IDocs are formatted incorrectly and I believe at least part of the reason is how I am converting the file content.
The root of my problem is that the flat file has a parent-child relationship between the document header and the document item and I want to maintain that since the IDoc type (FIDCCP01) has the same structure in the BKPF and BSEG segments.
Here is the flat (non-XML) file layout that is coming into the file adapter:
FileHeader
DocumentHeader
DocumentItem
DocumentHeader
DocumentItem
and so on (until the number of documents is complete
I would really like the content to be converted so that the line items stay under their parent document headers like this:
<FileHeader></FileHeader>
<DocumentHeader>
   <ItemHeader>
   </ItemHeader>
</DocumentHeader>
<DocumentHeader>
   <ItemHeader>
</ItemHeader>
</DocumentHeader>
But I keep getting this, where it lists the document headers first (one after another), and then all of the line items after the document headers like this:
<FileHeader></FileHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<ItemHeader></ItemHeader>
Is is possible to maintain that parent-child relationship from the flat file and pass it over to the XML?
Thanks,
John

Office 2013 - SharePoint Web App: How can I link a subform on two Master/Child controls?

I have a form in which I have placed a subform in a SharePoint Web App.
I also have 2 controls on the form, from which I'd like to link to two columns on the subform. How can I have two Master/Child linking relationships to a subform.
In Access desktop, it is done in a window "Subform Field Linker", like this:
Master Fields: Child Fields:
<sorry I could not include a link until my account is verified>
Thanks,

Hi Bruce,
>>Are subforms in web apps different in this regard?<<
Yes, there are two kinds of database. In an on-premise environment, Access 2013 apps are hosted by SharePoint 2013 while the data is stored in SQL Server 2012. SharePoint 2013 provides authentication, authorization, and security for Access 2013 apps.
The back-end tables, views, macros, and queries are stored in a SQL Server 2012 database.
You can get more detail about Access 2013 web app from link below:

Doubts about BP number in SRM and SUS

Hello everyone,
I have some doubts about the BP number, especially for Vendors.
I am working with the implementation of SRM 5.0 with SUS in an extended classic scenario. We will use one server for SRM and other for SUS. We will use the self registration for vendor (in SUS). My questions are:
- Can I have the same BP number in SRM and SUS?? Or is it going to be different??
- When a vendor accesses at the site to make a self registration in SUS, the information is sent to SRM as prospect (by XI) and there the prospect is changed as vendor? After that, is it necessary to send something from SRM to SUS again? (to change the prospect to vendor)
- When is it necessary to replicate vendors from SRM to SUS??
Thanks
Ivá

Dear Ivan,
Here is answer to all your questions. Follow these steps for ROS configuration:
Pls note:
1. No need to have seperate clients for ROS and SUS. Create two clients for EBP and (SUS+ROS).
2. No need of XI to transfer new registered vendor from ROS to EBP
Steps to configure scenario:
1. Make entries in SPRO --> "Define backend system" on both clients.
    You will ahev specify logical systems of both the clients (ROS as well as EBP)
2. Create RFCs on both clients to communicate with each other
3. In ROS client create Service User for supplier registration service with roles:
    SAP_EC_BBP_CREATEUSER
    SAP_EC_BBP_CREATEVENDOR
    Grant u201CS_A.SCONu201D profile to the user.
4. Maintain service user in u201CLogon Datau201D tab of service : ros_self_reg in ROS client
5. Create Purchasing and vendor Organizational Structure in EBP client and maintain necessary
    attributes. create vendor org structure in ROS client
6. Create your ROS registration questionnaires and assign to product categories- in ROS client
7. To transfer suppliers from registration system to EBP/Bidding system, Supplier pre-screening has to be
    defined as supplier directory in SRM server - EBP client.
    Maintain your prescreen catalog in IMG --> Supplier Relationship Management u2192 SRM Server u2192
    Master Data u2192 Define External Web Services (Catalogs, Vendor Lists etc.)
8. Maintain this catalog Id in purchasing org structure under attribure "CAT" - in EBP client
9. Modify purchaser role in EBP client:
    Open node for u201CROS_PRESCREENu201D and maintain parameter "sap-client" and ROS client number
10.Maintain organizational data in make settings for business partner
Supplier Relationship Management -> Supplier Self-Services -> Master Data -> Make Settings for the Business Partners. This information is actually getting getting stored in table BBP_MARKETP_INFO.
11. Using manage Business partner node with purchasers login (BBPMAININT), newly registsred vendors are pulled from Pre-screen catalog and BP is created in EBP client. If you you have SUS scenario, ensure to maintain "portal vendor" role here.
I hope this clarifies all your doubts.
Pls reward points for helpful answers

Prashant

Visualize master-detail relationships using SQL Edge 1.2

SQL Edge 1.2 released by Bay Breeze Software (http://www.baybreezesoft.com) is an Eclipse Rich Client application that allows users to execute SQL queries, browse schema information, and visualize master-detail relationships.
With SQL Edge, users can use only one query to retrieve data in a master table, and then browse data in all related detail tables. Users can also insert, edit, and delete table records in the data grids.
SQL Edge has four perspectives. The Query Perspective allows users run any SQL queries, while the Schema Perspective displays table schema information. There are two relationship perspectives. The Relationship Table View displays data in the master-detail style. The Relationship Tree View displays master table records as top-level tree nodes. The nodes can be expanded to reveal any level of related detail records. In addition, clicking any node will display the corresponding data in a detail grid.
The following summarizes SQL Edge's major features:
(1) Support any JDBC compatible databases.
(2) Allow users to specify JDBC drivers at run-time, and provide wizards to help setup JDBC connections. Easy to install, and easy to setup.
(3) SQL editor with syntax highlighting based on currently connected databases.
(4) SQL edtior allows users to execute SQL queries asynchronously. Users can cancel the execution by click the "Cancel" button or just close the SQL Editor.
(5) Schema perspective displays the table schema information, including column definitions, primary key, indexes, and foreign keys.
(6) Relationship table view displays the related data in master-detail style, with master table data shown in the top grid, and all related detail table data in a list of bottom grids.
(7) Relationship tree view displays the master table records as top-level tree nodes, and the related detail records as child nodes. Click any of these tree nodes will display the corresponding record data in a detail grid.
(8) Allow users to insert, edit, and delete records in the master and detail grids of the relationship table view and relationship tree view.
(9) Allow users to define master-detail relationships even between tables in different databases. This enables the relationship table view and relationship tree view to display data relationships between tables in different databases or without pre-defined foreign keys.

Hi, Martin.
Maybe you don't need a master detail relationship. Do you need to do changes in your detail block, or just queries?
If just queries, you can create your second block based on a From-Clause Query, and change the QueryDataSourceName property with a When-List-Changed trigger in your T-List.
I know this is a little vague but, without knowing what you need to do in the second block, I'm afraid to tell you more.
Feel free to mail me directly, if you need some pointers about Forms.

Does table STPOX contain parent-child relationship between components

Hello
I need to get a list of components of SO BOM.
FM CS_BOM_EXPL_KND_V1 exports an output table STPOX.
Does this table contain parent-child relationship between components? If yes , can somebody tell me which fields contain parent child id.
thanks

Hi,
STPOX is not a table, it is a structure & hence there is no storing of data in a structure. The table which stores this info is STPO.
To get the link you can refer to STPO-STLNR & pass this value to MAST-STLNR, this way you can link the child with its parent.

Vivek
