Hi,

SELECT bname name_textc FROM user_addr INTO TABLE itab_details

WHERE bname IN ('LB'). "(usr_nm).

In your select statement you are using IN (WHERE bname IN ('LB'). "(usr_nm).).

If you are using IN then usr_nm should be a range or select option. Instead you change your statment as :

SELECT bname name_textc FROM user_addr INTO TABLE itab_details

WHERE bname = usr_nm.

Hope this helps.

Hi Lokesh,

The first error that you are getting is because of the wrong data type declaration. If you look at your data declaration section, you will see that the

 usr_nm FOR cl_details=>wa_details-bname MATCHCODE OBJECT user_comp.usr_nm FOR cl_details=>wa_details-bname MATCHCODE OBJECT user_comp.

But in the method interface data declaration, the data type is different. So, have a look at the data declarations and check for the correct data type. This will resolve your problem.

For the second error, have a look again at the data declaration. As the Select statement expects an IN Statement for a Ranges or Select Options. The Data declaration seemed to be alright, but the data types may be different.

Hope this helps.

Thanks,

Samantak.
