stopping a loop node to iterate only once

[Former Member]

Hello,

I have a loop node in which i am interating thru an internal table. I dont have a table node before this loop, so any calculation i have to do is in the loop node. I want to ask is how to iterate the loop only once ?

Thanks,

Hi shehryar,

If you want to execute this loop only one time then write this code

loop at itab.

// do your calculation here

if sy-tabix = 2.

exit.

endloop.

Ps reward points if helpful

sy-tabix didnt work...

[former_member181962]

In the conditions tab.

YOu can specify the condition

sy-tabix = 1.

meaning that this node will be active for only that condition.

if you are certain that u want one record (or you want to loop only once), then use READ statement instead of loop.

read table itab with key fi = a1

f2 = a2.

if sy-subrc eq 0.

< this means entry is found>.

endif.

Hi,

You can also use Loop with where condition.

The where condition on a primary key in the internal table can give you a single record.

Are you talking about a loop node in Smartforms?

Hope this helps,

Hi,

can you set the result of the calculation in the structure that take the data of the internal table ?

(when you make a loop in smartforms, you set the data in a structure)

So you will have just to make a condition to didn't loop if the field where the calculation is made is empty or not.

Hi,

Give the Line 1 to 1 in the data tab of the Loop Node or read the first line in the Program Lines Node and display it in Template Node.

Hi,

You can give 1 to 1 in ROW tab under the Internal Table in the DATA tab of the loop node.
