Hi,
You can try this to highlight a particular column you want.
Suppose you got a method called fieldcatalog in a class definition.
fieldcatalog IMPORTING tablename TYPE lvc_tname
fieldname TYPE lvc_fname
emphasize TYPE lvc_emphsz
EXPORTING t_fieldcat TYPE lvc_t_fcat.
In class implementation.
METHOD fieldcatalog4.
x_fieldcat4-fieldname = fieldname.
x_fieldcat4-tabname = tablename.
x_fieldcat4-emphasize = emphasize.
APPEND x_fieldcat4 TO t_fieldcat4.
CLEAR: x_fieldcat4.
ENDMETHOD.
Calling the method.
CALL METHOD obj->fieldcatalog
EXPORTING
fieldname = 'Fieldname'
tablename = 'Internal_Table'
emphasize = 'X'
IMPORTING
t_fieldcat = t_fieldcat.
In Reuse_alv_grid_display.
Pass t_fieldcat
it_fieldcatalog = t_fieldcat
This will highlight the only column you want to highlight.
Regards
