How to avoid Move Corresponding

Hi All,

I have used Move-Corresponding in my code,which I want to avoid. Logic I have used is as follow:

I have 2  tables, table A and Table B.Now if there are 10 fields in table A ,then in table B there are those same 10 and 4 more fields.

After populating table A,I pass the values of those 10 fields to table B and update the value of the rest 4.

Code:

loop at <table A> into <wa_A>

     MOVE-CORRESPONDING <wa_A> to <wa_B>

        <WA_B>-field1 = <>.

         <WA_B>-field2 = <>.

         <WA_B>-field3 = <>.

         <WA_B>-field4 = <>.

          APPEND <wa_B> to <Table B>

ENDLOOP.

Please tell me a more efficient way of doing this.I want to avoid using Move Corresponding
