Help required for a Remote cube query

Question

Hi,
We are working on Remote cube, which has a source from a view built on R/3 base table. I need to extract the data to BW based on a current date due to huge volume of data(performance reasons) in the table. I have used an exit on R/3 to restrict to current date but the extract checker was showing the valid data ie only for current date. When i had built a query on Remote cube, the Report was showing complete data(restriction not working). We have even tried using an inversion routine in transfer rules to pass the selections to the Source system even then it doesn't work. Could you help if you have come across same kind of situation or you can suggest an alternate solution on the same but we have to use Remote cube.
Any suggestions asap would be highly appreciated and rewarded with full points.
Regards,
Raj

Answer 1

I can think of two ways to do it
Simple with no ABAP coding is a view
Create a view between a timestamp table and your big table
Put an entry into your timestamp table of the current date - then use a selection of this inside the view
Unforutunately you cannot use SY fields inside database views (otherwise you could have used these as a selection condition in the view)
The best way to do it is using a function module and passing the data from the query into the SQL statement
I prefer to do it the last way and also pass data through a generic structure - thus you manipulate the data inside the intial loop in the function module and don;t utilise further loops downstream in transfer rules
(to try and keep the reponse time down)
