internal table read

Former Member — Mon, 01 Oct 2007 06:10:45 GMT

I am reading an internal table twice in a single go. I am getting the first and the second record as obvious while executing the perform once.

What I need to do is, if I read the table in the next go or I execute the perform again, I should get the record third and fourth as a result.

The code is something like this:

Do 2 times.

Perform ABC -> Reads table once and gets the first record.

Perform XYZ -> Reads table once more and gets the second record.

Enddo.

Can anyone suggest logic for this.

Point will be rewarded for the correct logic.

Regards

Hi Vishal-

It depends on what code you have written in Performs..Can you send the complete code so that I can help you out??

Cheers

Vishal,

Use sy-tabix to direct your READs..

Try using a static var.

Statics: l_stat.

read table xyz index l_stat. " incrment l_stat

read table xyz index l_stat.

I am not pretty clear with your requirement but here is a pseudo logic.

clear l_counter.

Do 2 times.

l_counter = l_counter + 1.

Perform ABC -> Reads table once and gets the first record.

l_counter = l_counter + 1.

Perform XYZ -> Reads table once more and gets the second record.

Enddo.

In first DO Loop pass, L_COUTER will be 1, perform ABC will read first record, then counter will value will be 2 and XYZ will read second record.

In the next loop pass, counter will become 3 and ABC will read third record. Then Counter will become 4 and XYZ will read 4th record.

Make sure in PERFORM ABC and XYZ you use COUNTER while reading internal table.

make use of LOOP statement instead of READ statement

count = 0.

loop at itab where field = value.

count = count + 1.

if count = 3.

itab3 = itab.

elseif count = 4.

itab4 = itab.

endif.

endloop.

But a read statement always returns first statement satisfying the criteria then its always going to return the same record for the same selection criteria.

Better keep a counter for the index no to be read.
