How to search char field data using wild card option with no casesenstive?

ex - if i give in search - a*

it should able to pick up all the records ..

ABAP

Abap

abap

abaP

i tried like this

ranges: r_name for kna1-name1.

r_name-sign = 'I'.

r_name-option = 'CP'.

if name is initial.

r_name-low = '*'.

else.

r_name-low = name.

endif.

append r_name.

but this is working fine for wildcard.. but how to extend this for with out case sensitive search?

thanks.
