Problem in creating datasource

Question

Hi,
   I need to create a master datasource for a table but only for some fields in that table. Some of the fields are of type Timestamp but i need only Date. So I thought of creating a structure with only required fields of that table and changed data type. In the user exit or BADI, thought of writing the code for extracting the data from that table and doing some manipulations. In RSO2 transaction while creating a master datasource i am not able to specify the structure created? Is there any other way to proceed with this scenario?
Thanks!

When you want to create generic datasource and need to use manipulation of table data go for function module based datasource.
First create a structure and in RSO2 choose function module based datatsource and place your function module and structure.
PS: You need not use CMOD coding instead go for function module.
Hope this helps.
