Type pool: slis

Hi experts
pls could you explain what is TYPE-POOLS: SLIS clearly in ALV program. i want to know what is the basic structure of slis and what is type pool. thax heaps.......
points awarded...
kondal

SLIS is a type pool or group and is nothing more than a collection of TYPE statements. When you use the TYPE-POOLS: statement in your program, and name the type group SLIS, this gives you access to these TYPES so that you can use them in your DATA statements. For example, if you want to declare an internal table for the field catalog.....
type-pools: slis.
data: ifldcat type slis_t_fieldcat_alv.

Where did type-pools: SLIS store in database?

HI GURU'S,
In which table did the type-pools SLIS will store in datadictionary .

Hi
The type groups are stored in the table "TADIR".
Go the Transaction Code SE16 and enter the table name "TADIR" and execute.
On the selection screen Enter OBJECT = TYPE and DEVLOPMENT CLASS = Slis and execute.
Hope it helps.

ALV Using TYPE-POOLS: SLIS

hi
Using TYPE-POOLS: SLIS
I created a "special group" using structure
slis_sp_group_alv
and appending it to table of type
slis_t_sp_group_alv
i call this special group internal table using the function module:
"REUSE_ALV_HIERSEQ_LIST_DISPLAY"
the sample code will look something like this:
DATA: gt_sgroup TYPE slis_t_sp_group_alv.
CALL FUNCTION 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'
IT_SPECIAL_GROUPS = gt_sgroup.
My question is How should i add the contents of my internal tables which i create using 'fieldcat' into this "special group" say 'xyzw' is the name of my special group.

Hi Deepak,
First you have to populate the internal table ( i.e, Fill the internal table ). Then pass that internal table to that function u r calling.
See d below code for your reference for how to add the rows to the internal table. Follow similarly,

Can any one describe ne type pool slis?

can any one describe ne type pool slis and its fields.

Hi Ansuman Parhi,
1. in se11
2. in Type Group
(Also choose that corresponding radio button)
3. enter SLIS
4. Press F7 or Display button
Now u can see the Types available in SLIS
See the Comments in Source Code for understanding the use of each type of SLIS..
also have a look on below thread

Type-pools:slis

Hi,
I have some doubts
1. what is pool table?
2. what is slis table & what is the advantage?
3. Why have to use the slis in ALV?
Regards,
Satish.

HI Satish,
Here is the answer for your first question.....
1. POOL TABLE
Suppose we have 15 different
tables in ABAP Dictionary
and only 1 table in physcial table.
So, the data of all these 15 tables
will be stored in the 1 physical table.
(it will be stored in a raw data format,
but it will be provided to the programs
in a structured way)
This concept is called POOL.
If all these 15 tables have 10 records each,
Then,
In the poooled table there will be
15 x 10 = 150 records.
Each record of the physical table
contains,
name of the table
Primary key value of the table
so that to identify the record.
Table pools (pools) and table clusters (clusters) are special table types in the ABAP Dictionary. The data from several different tables can be stored together in a table pool or table cluster. Tables assigned to a table pool or table cluster are referred to as pooled tables or cluster tables.
A table pool or table cluster should be used exclusively for storing internal control information (screen sequences, program parameters, temporary data, continuous texts such as documentation). Data of commercial relevance is usually stored in transparent tables.
Table Pool
A table in the database in which all records from the pooled tables assigned to the table pool are stored corresponds to a table pool.
The definition of a pool consists essentially of two key fields (Tabname and Varkey) and a long argument field (Vardata).

About type pools in ddic

i would like to about type pools pls let me why we use this and how to create these type pools and what is the advantage of using type pools
thanks in advacnce

hi,
This is taken directly from the HELP.
Type Groups
Before Release 4.5A, it was not possible to define standalone types in the ABAP Dictionary to which you could refer using a TYPE addition in an ABAP program. It was only possible to refer to flat structures. Structures in programs corresponded to the structures of database tables or structures in the ABAP Dictionary. In ABAP programs, you could only refer to database tables and structures in the ABAP Dictionary using LIKE. It was, however, possible to refer to individual components of the Dictionary type. Complex local data types such as internal tables or deep structures had no equivalent in the ABAP Dictionary. The solution to this from Release 3.0 onwards was to use type groups. Type groups were based on the include technique, and allowed you to store any type definitions globally in the Dictionary by defining them using TYPES statements.
The definition of a type group is a fragment of ABAP code which you enter in the ABAP Editor. The first statement for the type group <pool> is always:
TYPE-POOL <pool>.
After this came the definitions of data types using the TYPES statement, as described in Local Data Types in Programs. It was also possible to define global constants using the CONSTANTS statement. All the names of these data types and constants must begin with the name of the type group and an underscore:
In an ABAP program, you must declare a type group as follows before you can use it:
TYPE-POOLS <pool>.
This statement allows you to use all the data types and constants defined in the type group <pool> in your program. You can use several type groups in the same program.
Let the type group HKTST be created as follows in the ABAP Dictionary:
TYPE-POOL hktst.
TYPES: BEGIN OF hktst_typ1,
col1(10) TYPE c,
col2 TYPE i,
END OF hktst_typ1.
TYPES hktst_typ2 TYPE p DECIMALS 2.
CONSTANTS hktst_eleven TYPE i VALUE 11.
This type group defines two data types HKTST_TYP1 and HKTST_TYP2, as well as a constant HKTST_ELEVEN with the value 11.
Any ABAP program can use this definition with the TYPE-POOLS statement:
TYPE-POOLS hktst.
DATA: dat1 TYPE hktst_typ1,
dat2 TYPE hktst_typ2 VALUE '1.23'.
WRITE: dat2, / hktst_eleven.
The output is:
1,23
11
The data types defined in the type group are used to declare data objects with the DATA statement and the value of the constant is, as the output shows, known in the program.
In short, type-pools or type groups are like little include programs where you store a bunch of TYPES statements. You can then use these types instead of defining them manually in your program. All you need to do is include the type-pool in your program.

TYPE-POOLS: TRUXS

Hi,
What is type-pools? why we are using truxs type-pools. what are the benifits of truxs type-pools. Please explains these thinks..
Thanks
margani

Hi
Type pool is a collection of pre defined data types..
Frequently used data types in programming are clubbed into a type pool so that if u write in ur code:
TYPE-POOLS: slis.
the declarations in SLIS will apply to ur code also..
SLIS contains data definitions for ALV structures & internal tables. so that u dont need to declare alv data everytime in ur program..
check out type pools: ICON, etc.. In SE11, type groups..
We can use ABAP ALV LIST and GRID function modules to display Normal LIST and Hiearchical LISTS .
All the definitions TYPES and STRUCTURES and CONSTANTS are defined
in the TYPE-POOL 'SLIS' ,so it should be declared first.
TYPE-POOLS : 'SLIS' .
To display ALV LISTS the function module used are :
REUSE_ALV_LIST_DISPLAY "For Normal LIST
REUSE_ALV_HIERARCHICAL_LIST_DISPLAY "For Hierarchical LIST
To display ALV GRID the function module used are :
REUSE_ALV_GRID_DISPLAY . "For GRID display
The most important component of the ALV is the FIELDCATALOG which is of
TYPE SLIS_T_FIEDLCAT_ALV
or of
TYPE STANDARD TABLE OF SLIS_FIELDCAT_ALV .
The line items of the field catalog are of
TYPE SLIS_FIELDCAT_ALV .
FIELDCATALOG
To prepare field catalog certain fields are essential .There are various other fields allowing for vaarious possibilities and display options.
TABNAME
FIELDNAME
REF_TABNAME
SELTECT_M
e.g.
DATA: WS_FCAT TYPE SLIS_FIELDCAT_ALV . "LINE ITEM OF FCAT
DATA: IN_FCAT TYPE SLIS_T_FIELDCAT_ALV.
WS_FCAT-TABNAME = 'MARA'.
WS_FCAT-FIELDNAME = 'MATNR'.
WS_FCAT-SELTEXT_M = 'Material Number'.
APPEND WS_FCAT TO IN_FCAT .
CLEAR WS_FCAT.
WS_FCAT-TABNAME = 'MAKT'.
WS_FCAT-FIELDNAME = 'MAKTX'.
WS_FCAT-SELTEXT_M = 'Material Description'.
APPEND WS_FCAT TO IN_FCAT .
This will create fieldcatalog with two columns for displaying material and material description .
RESUSE_ALV_LIST_DISPLAY.
The following FM is used to display the data in the internal table in the form of ALV
LIST. The Event table is only required if event handling is being done.
CALL FUNCTION 'RESUSE_ALV_LIST_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = W_REPID "of TYPE SY-REPID and

IT_EVENTS = IN_EVENTS " of TYPE SLIS_T_EVENT
TABLES
T_OUTTAB = IN_DATA "internal table conatining data
"corresponding to IN_FCAT
EXCEPTIONS
PROGRAM_ERROR = 1
OTHERS = 2
IF SY-SUBRC NE 0.
MESSAGE ENNN .
ENDIF.
REUSE_ALV_EVENTS_GET.
This FM is used to get the default event table of the ALV LIST DISPLAY.
The IN_EVENTS internal table is of TYPE SLIS_T_EVENT. This table contains
all the events wrapped up in the ALV LIST or ALV GRID and consistsof two fields
NAME and FORM .The NAME corresponds to names of the events like TOP_OF_PAGE and END_OF_PAGE ,USER_COMMAND and FORM will contain the name of the FORM ROUTINE that will be called dynamically through callback mechanism when the particular event will fire and is initial for all events bt default and has to be filled for
events for which handling is required.
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
EXPORTING
I_LIST_TYPE = 0
IMPORTING
ET_EVENTS = IN_EVENTS[].
e.g.
DATA: W_EVENT TYPE SLSI_ALV_EVENT "LINE ITEM OF EVENT TABLE
DATA: IN_EVENTS TYPE SLSI_T_EVENT . "Internal table containing events
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
EXPORTING
I_LIST_TYPE = 0
IMPORTING
ET_EVENTS = IN_EVENTS[].
RTEAD TABLE IN_EVENTS WITH KEY NAME = 'TOP_OG_PAGE'
INTO W_EVENT.
IF SY-SUBRC EQ 0.
MOVE 'F3000_TOP_OF_PAGE' TO W_EVENT -FORM.
MODIFY IN_EVENTS FROM W_EVENT INDEX SY-TABIX.
ENDIF.
Here the FORM ROUTINE 'F3000_TOP_OF_PAGE' is being set up for the
event TOP_OF_PAGE which will fire when the ALV LIST will be displayed ,This form
will be called dynamically by th ALV LIST display during top_of_page event and for this the modified Events internal table has to be passed to the FM 'REUSE_ALV_LIST_DISPLAY' in the exporting parameter IT_EVENTS. Failing this the form '3000_TOP_OF_PAGE' will not be called . This event is used for placing heading information like Current date and time and the name of the report.

Alv without type-pools statement

hi experts,
can we use reuse_alv_list_display, function module in a report......
without declaring an type-pools: slis. is it possible.
if yes give me an example.....
what are all the mandatory requirements for an alv report.............

Hi ,
SLIS is basically used to get the various structures and data types which you use in the FM called by the program , so if you want to implement it without SLIS then you will have to declare all the data types in your program the same way it is declared in SLIS .
Why are u a hesitant in using the type pool?

Type pool

what is the type pool used for placing a drop down list box on the module pool screen

TYPE-POOL
The introductory statement TYPE-POOL can only be used for type groups (type T programs). A program introduced with the TYPE-POOL statement can only contain global type definitions and constants declarations. The CLASS-POOL statement is generated automatically where required by the ABAP Dictionary - you should not insert it into programs manually.

Diff. bet TYPE-POOL & TYPE-POOLS

Hi,
Could anyone please tell me the difference b/w TYPE-POOL & TYPE-POOLS statements with some examples

Oh, I think I see what you are talking about. In a report program write this.
report zrich_0002.
type-pools slis.
Now double click on the SLIS. This takes you to the type pool. This first statement in the code is TYPE-POOL. This is just how you define the start of the type pool. Sort of like REPORT ZRICH_0002 or FUNCTION ztest. When developing a type pool you will begin the code by saying TYPE-POOL ZTEST. Then, to use the type pool in your program, you will say TYPE-POOLS ZTEST.
Make sense?

HI,
Its nothing but abap code,
where some bunch of
TYPES (data types) and some data declaration,
is already done.
(which we can use in other programs)
(as the name suggests,
it is a pool (bunch)
of TYPES.
It is type-pool (bunch of types)
required for ALV purpose.
(eg. variable for field catalogue, alv layout etc)
Advantage is that we have to use such types,
just by referring, them, (bcos they are already defined)
Types-Pool contains the TYPE declaration which is global and can be used across any program.Once we write
TYPE-POOL : <pool name>
It will include all declariuon in the program and we can refer those.
There are many standard types pool provided by SAP
like SLIS,ICON,ABAP etc.
However also,we can create our own Type-Pool using
SE11->Type Group.

Laxmi.

Type Pools

Hi All,
     What is meant By Type pools and Class pools. It contains Types like SLIS,    VRM. What is the use of it.
Thanks in Advance

Vijay ,
Pls. go through this.
10.     What is a table pool?
A table pool (or pool) is used to combine several logical tables in the ABAP/4 Dictionary. The definition of a pool consists of at least two key fields and a long argument field (VARDATA).
11.     What are pooled tables?
These are logical tables, which must be assigned to a table pool when they are defined. Pooled tables can be used to store control data (such as screen sequences or program parameters).
Pls. mark if useful
12.     What is a table cluster?
A table cluster combines several logical tables in the ABAP/4 Dictionary. Several logical rows from different cluster tables are brought together in a single physical record. The records from the cluster tables assigned to a cluster are thus stored in a single common table in the database.

Type pools information gathering

Hi guru's,
    I have one problem. In my program i have to find the type of variable.
Ex
Data a type standard table of slis_t_fieldcat.
Data b type slis_t_fieldcat.
so A is an internal table
and B is an work area.
Data c type abab_bool.
now C is a variable.
Now in result i have to say like this.
a         - Internal table.
b         - work area
c         - variable
how to find the
data type particularly for TYPE POOLS.
Pls help me.
Thanks & Regards,
Florian.

hi vijay,
     As you mensioned, i used the class CL_ABAP_TYPEDESCR. But the problem is that it returns three types of instances of,
     CL_ABAP_TABLEDESCR       - for Internal Table
     CL_ABAP_STRUCTDESCR     - for Structure
     CL_ABAP_ELEMDESCR        - for Variables.
     Now, with this instance, how to get there class name? if i get it, i will cross check with these class names.
     desc ?= cl_abap_classdescr=>describe_by_data_ref(
    p_data_ref           = sli
     In this statement, how to get a class name of the instance desc?
