Problem with the WHERE condition

Hello Friends,

I have some problem with the where condition.

Within the method of my Class, I have written a select query.

select * from table TAB1 into table lt_TAB1 where FIELD1 = ls_STRUCTURE-FIELD1.

Here ls_STRUCTURE is getting filled in the method based on the screen fields. The User enters * in the screen field FIELD1, then this query doesnt work. How to modify the query so that this works?

Thanks & Regards,

Raju
