How to transfer data to work area. If internal table and work are have different structures.

HI,

I am trying to pass data from an internal table to work area. Work area and internal table having different number of fields and structure.

I have an excel sheet with entries from different table. another another sheet giving corresponding name of table.  I have to modify the database table according to those entries.

.

I have used dynamic data creation for this purpose.

Please find the program attached below:

it_tables: contain table names

it_entries: contain table entires

   LOOP AT it_tables INTO wa_tables.

     tabname = wa_tables-tab_name.

     CREATE DATA w_dref TYPE STANDARD TABLE OF (tabname).

     ASSIGN w_dref->* TO <i_tab>.

     CREATE DATA w_dref LIKE LINE OF <i_tab>.

     ASSIGN w_dref->* TO <wa>.

lv_count = lv_count + 1.

     READ TABLE it_entires INTO <wa> INDEX lv_count.

the above read statement is not able to pick up entry. Since it_entries is made of 15 columns of 50 length and wa structure is same as table

name provided in second sheet.

Kindly help!

Any other way I can update tables, will also be great.

Awaiting your expert replies!.
