Hi Hajeera,
% is useful if you want to fetch records matching some pattern (starting with/ending with/in the middle).
Eg1:
If you want to fetch all materials from MARA starting with 123, you can use
select matnr from MARA into table itab
where matnr like '123%' (Similar to 123* via SE16 tcode)
Eg2:
If you want to fetch all materials from MARA ending with 123, you can use
select matnr from MARA into table itab
where matnr like '%123'
Regards.
