Hi,

slis_t_fieldcat_alv is a Table type.

and slis_fieldcat_alv is a Structure....

If you dec a var in your prog wrt slis_t_fieldcat_alv ...you will get a Internal Table......whereas with other one you will get a structure

Hi..

difference between slis_t_fieldcat_alv and slis_fieldcat_alv.

first will create a internal table which can have various entries while second will create a structure or work area,it can have only one entry.

Hi Chandresh Bajpai,

SLIS_FIELDCAT_ALV is a LINE TYPE.

SLIS_T_FIELDCAT_ALV is a TABLE TYPE. Because it has

OCCURS addition.

Hi,

When you are using REUSE_ALV Functions except RESUE_ALV_GRID_DSPLAY_LVC function module all needs

SLIS_T_FIELDCAT_ALV.

if you are using OO ALV and LVC function then you have to use LVC_T_FCAT.

There is a case where you can use both check this

slis_t_fieldcat_alv is a table type and slis_fieldcat_alv is a structure.

when u declare a data variable using slis_t_fieldcat_alv, it will create an internal table whereas slis_fieldcat_alv will create a work area.

DATA: gt_fcat TYPE SLIS_T_FIELDCAT_ALV, "Internal Table
          gs_fcat TYPE SLIS_FIELDCAT_ALV. "Work Area
