How to proccess 15000 records?

[Former Member]

Hello friends,

I am uploading one text file with 15000 records and i am proccessing it with i_tab.

But it slows down the performance.

So, new requirement is to process first 1000 records then next 1000 records so on.

How can we do that?

regards,

Rh

Hi,

Either you split your text file by batches say 5K records per file or you can run it in background.

Hi

Try like this.....

Loop at itab.

Counter = counter + 1.

"Prepare another internal table of same type as itab.

jtab = itab.
endloop.
 if counter ("your condition)
Loop at jtab.
---

---
endloop.

Hi

Keep a counter. and write the loop like this..

Loop at itab.
 
Counter = counter + 1.
 

 



if counter = 1000.
call transaction
counter = 0.
endif.

endloop.
