Hi,

We can genarate a generic datasource on a DBtable, and the collection of different tables which

supplies different fields-which is a image of table we call it as VIEW, and from a infoset query and a

programming module(Function module).

Hoep this info helps you.

Assign points if it is worth.

Thanks,Ramoji.

Re: Difference between table, view, info set and function module

Hi

Generic DataSource : The datasource u create manually using rso2 using the tables, view or function

module as per ur requirement.

view is a window sort of used to provide join between two or more tables for example if i want field x

of table M should be equal to field y of table N then i will create a view in other words u can say that a

view is a join between two tables.

infoset: is a multiprovider which provides us join condition on cube ods and master data.We can

create query on infoset and thus the output of of the query will be result of the join conditions provided

in the infoset.

function module : is other method to create the Generic datasource with.

here u can provide importing exporting parameters as well as you can write the code as per your

requirement for a particular field.

thanks

Hi Sreenivas,

Table: When you want to extract multiple fields from one tabel to BW, we use a

Table.

View: if you want to extract data from multiple tables, we use View. In this case atleast one field

should be common in both the tables.

Infoset: Using an infoset, we can extract data from multiple tables very much like a view but there is

no need to have a common filed in both the tabels. generally in real time the functional consultant will

provide the Infoset, you need not create it.

Function Module: In case of Table, View and infoset, extract structure is automatically formed but in

case of function module, extract structure and function module needs to be created. You can write the

code here as per the requirement.

Pkease assign points if it is helpful.

Regards,

Rahul
