Another good thing with FOR loop. Earlier it was possible to use a data (LS_SPFLI) to iterate over the internal table but now it is possible to even use a field symbol <FS_SPFLI> to iterate.
Here this how it works-
Interesting thing is that- after FOR LOOP is over, the line LS_SPFLI still in memory and holds the last iteration data/values but with field symbol it is un-assigned once the iteration is over.
Here is another look-
Also we can change particular column values in the target adding the BASE addition- specifying the column names and values
