Absolutely possible.

But that's recommended guideline.

Hi Sri,

Loop inside loop is possible but on certains conditions where its unavoidable.

Possible, but may cause performance problems. See:

Hi sri,

it is posible clearly.

see this code.

data: t_spfli type table of spfli with header line,

t_sflight type table of sflight with header line.

select * from spfli into table t_spfli.

select * from sflight into table t_sflight.

loop at t_spfli.

write:/ t_spfli-carrid,

t_spfli-connid.

loop at t_sfplight where carrid eq t_spfli-carrid

and connid eq t_spfli-connid.

write / t_sflight-fldate.

endloop.

endloop.

Plz Reward if useful,

Mahi.

So depending on ur requirement u can use different alternative.

Plz reward points if useful

Hi,

It is definitely possible but it depends how you want to use it.. If your loop has selects from database tables it is really not feasible and should not be done but if it is reading from the internal tables it will not cause problems with database but your ABAP memory will be affected.

Also loop in loop means that your performance will always take a beating.

Hi sri,

Loop inside a loop is possible until you are not using a SELECT inside a LOOP.
