Data extraction Issue

Hi Experts,

I am trying to load data from a generic datasource, which is based on a view.

The view contains 5 tables - EKBE,EKKN,EKPO,T001 and EKKO.

The join condition is as follows:

EKKN EBELN = EKBE EBELN

EKKN EBELP = EKBE EBELP

EKPO MANDT = EKBE MANDT

T001 MANDT = EKBE MANDT

EKKO MANDT = EKBE MANDT

Now, when i try to check data in rsa3, it throws a dump.

I then tried to check out the data in the view.

I entered a particular PO Number as the selection, and then clicked on "No. of entries" button.

It takes a long time for processing and then it gives a message "Maximum Runtime Exceeded".

Kindly let me know what should be done for this.
