hello sir,

slis_fieldcat_alv

slis_T_fieldcat_alv

what it means, what is the difference between those two

i am expecting tour replay

slis_fieldcat_alv is a structure

slis_t_fieldcat_alv is internal table which has structure of slis_fieldcat_alv

goto se11 -> type group : SLIS

find : slis_fieldcat_alv then slis_T_fieldcat_alv.

<b>Addition</b> :

<u>slis_T_fieldcat_alv</u>

1. encapsulate slis_fieldcat_alv structure.

2. this is the one that you should pass when you call REUSE_ALV_LIST_DISPLAY (one of function to build alv report)

slis_fieldcat_alv = it's a structure for internal use to build <b>slis_T_fieldcat_alv</b>.

Hi,

Type-pools: Type groups or type pools are created using the ABAP Dictionary tool and are introduced with the TYPE-POOL statement. They may not contain any screens of their own or any processing blocks. Type groups are exclusively used as containers for global data types which can be made visible in any ABAP program using the TYPE-POOLS statement.

Type-pools SLIS is used with the creation of ALV grid using function modules.

REUSE_ALV*

slis_fieldcat_alv is a structure

and slis_t_fieldcat_alv is an internal table of type slis_fieldcat_alv

Hope the above explanation helps.

Hi selva,

1. slis_fieldcat_alv

slis_T_fieldcat_alv

ALV type pools,

uses

INTERNAL TABLES <b>WITHOUT</b> HEADER LINES.

Hence, slis_T_fieldcat_alv

is a internal table type.

2. For working on this internal tables (without header line),

we need a CORRESPONDING - WORK AREA

which is slis_fieldcat_alv
