what is type-pools: slis and why we use this in alv ?

Hi,

with that statement you can import type of data to build an alv list, like slis_t_fieldcat_alv , slis_t_sortinfo_alv etc..

That's all.

Hi TYPE-POOL is a collection of data types and internal tables..etc with generic data declarations.

the type-pool will contain a set of related data declarations which will support standard programs and function modules.

for example in ALV you will use Field-catalog. SLIS will contain declaration for standard field-catalog. just click on that SLIS .. that will take you to type-pool. by having a look you will get basic understanding.

in ALV we will use SLIS because it will contain declarations for all most all the strucutures we will need in ALV.

hi,

SLIS is a type group or type pool. All it is is a development object which contains a bunch of TYPES statements. IN this case, it contains all of the TYPEs that you would need to use when doing ALV programming. So for example, you want to have an internal table for your field catalog, then you want to use the TYPE slis_t_fieldcat_alv. So in order to use this type, you will need to "include" the type group.

Type-pools: SLIS.

Now you can reference the type.

data: filedcat_alv type slis_t_fieldcat_alv..

in abap datatypes are three types

1) predefined data types

n,c,i etc

2)user defined data types.

by using types statement we can declare these

3)abap/4 types

by using type pools we can declare these

type pool slis is nothing but global declaration of variables & internal tables

so that we can use in our abap\4 programs

we can design field catalog ,events and some other functionality it provides

see below example

REPORT ZPRG8 .

TABLES: LFA1, EKKO, EKPO.

Hi,

with

type-pool slis.

you allow your report to use the "type pool" declared in the slis file.

The data type that u import are all that are in the slis file (double click on the slis word).

So when you write something of this:

DATA i_fieldcat TYPE slis_t_fieldcat_alv WITH HEADER LINE.

the report search the type slis_t_fieldcat_alv in slis file where is specificated.
