field symbol

[Former Member]

hi

just wanted to confirm

if we use field symbol in a loop

loop at gi_result assigning <fs_result>.

we dont need to use the command modify to change a field in the internal table, right?

[JozsefSzikszai]

right!

Of course right. When you are using field-symbols you are accessing the memory directly. So within a LOOP AT ... ASSIGNING, you're handling the row in the table directly.

Yes...we don't have to use modify statement as the after field symbol assignment the field-symbol will point to the memory location of the current internal table index.

Just to be more precise: a field symbol is not a pointer, and you are writing directly into the storage location. So modify is obsolete and in addition the loop will be much more performant because no memory-to-memory copy is necessary.

Absolutely right!
