generic datasources using function modules

[Former Member]

can anyone plz explain how to create generic datasources using function modules.

i mean, creating datasources using views makes sense but how does a function module indicate what fields i want to include in my datasource????

And, if you want some sample, just make a search or take a look here.

Hope it helps!

hi Ssree & roberto,

thanx for the warm welcome and prompt reply!

I am working on this....and come back later as and when a problem arises.

As of now....I am not able to understand the upper & lower limit settings for safety interval in generic delta and .....concept of LUW...(i noted that the LUW field pointed in the PDF link SREE gave me has sometimes value of around 2000 .....so is it that a single recod extraction can become a LUW?????)

and roberto .....I am still trying to figure out how best to understand the concept of populating my datasource using function module...whether just mentioning the field names in a view and including that solved the purpose!

I will come back with my remaining doubts sooner....

PLZ try to clear these doubts ...!!

iF just mentioning the field names in a view and including that solves your needs...you don't have to use function module, but it's enough a view...no doubt !

But, sometimes a FM is necessary if you need to apply some complex calculation or business logic (lookups, alternatives scenarios...)...

FM is only one more opportunity !

Then, LUW stands for Logical Unit of Work consisting of dialog steps (that can include more than a single record!), whose changes are written to the database in a single step...

take a look here:

Hi Sudhir,

Also, take a look at the how to guide

http://service.sap.com/bi -->infoindex -->delta handling (how to create generic delta). You would need a oss user id.

Hope it helps,
