How to – Configure a Join.

 There are two type of commonly used joinsImplicit JoinExplicit JoinImplicit Join: – Implicit Join are those which are already define in Siebel and whichare internally use by the Siebel to pull the values from the other than base table.example: – join between base table and extension table like S_OPTY andS_OPTY_X and join between S_PARTY and S_ORG_EXTExplicit Joints: – Explicit Joints are those which are define by the developer tocreate the relationship between two tables.Let’s take a real life example to understand the concept of Joins better.We have one table of the Employee where Name, Employee Id and otherinformation about the employee is stored.Another table stores a list of Cities.Requirement is to know which user stays in which city. There are two ways to doit

Store city in the Employee table which will result in data redundancy.Store Primary key of city table in the employee table and pull the values at therun time, which is more efficient and makes more sense.

 To implement second approach we use joins in Siebel. You have to follow the following five steps to have joined field on UI in Siebel1. Identify the column to be used as Foreign key.2. Configure field which will store the primary key of join table.3. Configure a join.4. Configure join specification.5. Add a field which will be used at Applet.An example will make things more clear.Suppose we want to have Opportunity Name on the Quote Applet. Here is a step

by step procedure with screen shots explaining how to do that.1. Identification of Column to act as foreign key.

 To configure a Join, first of all we have to find out a column in the base tablewhere we can store primary key say (ROW_ID) of opportunity in quote which willbecome the basis of join.If there is no column vacant in the base table we can use extension table for thatbase table e.g S_DOC_QUOTE_X for the S_DOC_QUOTE.Note: Make sure that the column you choose is not being used by any other BCor any other field of same BC.2. Configure Field in Business ComponentGo to Business Component > Field

Create a new recordEnter the name of the field.Enter extension table name in Join field if the column you identified belongs toextension table otherwise go to step 5Select the Column identified in column Field.Note: The column which you have selected must have physical Type varchar.

Our Foreign key is now ready for use. Now we have to configure a joined Fieldwhich will use this foreign key3. Configure/Create a JoinGo to Business Component > JoinCreate new record.Give name of the table with which you want create join ( S_OPTY in our case)

Give Name in Alias (New in our case).Check the Outer join Flag (Very Important).

Go to Object List Explorer (OBLE) on the left hand side and click + sign beside

 join there will be two options Join Specification and Join Constraints4. Configure Join SpecificationCreate New Record.Give Name in the Name field.Destination Column is given by default when insert a new record. You canchange it if you want to.In the Source field give the name of the source field (OptyID) which you haveconfigured earlier to be used as Foreign Key.

5. Configure the field (Opportunity Name) which you want to display on the UserInterface.

Go to Business Component > FieldInsert New RecordGive Name in the Name FieldEnter the Join Alias which you have given for the join you created.Select the Name (for Opportunity Name) in the column field. Column name hererepresent the data that you want to pull from opportunity.

 6. Configure the Control in the Applet (UI).Go to Applet > Control (if Form Applet)

Go to Applet > List > List Column (if List Applet)Create New Record.Enter the NameEnter the name you want to display on UI in Caption Override FieldEnter the Name of the field you created in Field column

Don’t forget to map this field in Applet. Right Click on the corresponding Appletand map it.

Now compile the entire project which you have made the changes and you willbe able to see this joined field in the Quote Applet as shown in the picture below.

When you see this field in User Interface it will be read only because when thedata is pull from the join table it is only read only, to make it editable you haveconfigure Pick Applet on this field.
