Hi Roger,
Use field symbols as below
FIELD-SYMBOLS <lo_row_content> TYPE data.
or
FIELD-SYMBOLS <lo_row_content> TYPE any.
and use this filed symbol in RTTI
we cannot define like
data lo_row_content type data in any programme except interface of programme
but we can define
data lo_row_content type ref to data.

Sreenivas.
