Regarding internal table read.

Hi,
i want to read internal table and compare the one variable existing with in from date and to date.
the psudo code is like this
READ TABLE L_TABEMPLOYEE INTO L_WAEMPLOYEE WITH KEY EMPLOYEE = SOURCE_FIELDS_RULE-PERNR
ULTIMO BETWEEN L_WAEMPLOYEE-DATEFROM AND L_WAEMPLOYEE-DATETO.
but this statement gives error.
how to code for the same requirement.
regards,
swami.

Hi,
Recode like this.It will definitely work
LOOP AT L_TABEMPLOYEE INTO L_WAEMPLOYEE
 WHERE EMPLOYEE = SOURCE_FIELDS_RULE-PERNR
 AND ULTIMO > L_WAEMPLOYEE-DATEFROM
 AND ULTIMO < L_WAEMPLOYEE-DATETO.
<Write what you want to do here >
ENDLOOP.
Please reward if useful
Thanks Arjun

Regarding Internal table and access performance

hey guys.
In my report , Somehow i reduced the query performance time by selecting minimum key fields and moved the selected records to internal table.
Now from this internal table i am restricting the loop
as per my requirements using where statements.(believing that internal table retrieval is more faster than database acces(using query)).
But still my performance goes down.
Could you pls suggest me how to reduce the execution time
in abap programming.
I used below commands.
Read using binary search.
loop ...where statement.
perform statements.
collect staements.
delete itab.(delete duplicates staements too)
sort itab(sorting).
For each above statements do we have any faster way to retrieval records.
If i see my bottle neck at se30.it shows
ABAP programming to 70 percent
database access to 20 percent
R3 system as 10percent.
now how to reduce this abap process.
could you pls reply.

Hello Ambichan,
It is difficult to suggest the improvements without looking at the actual code that you are running. However, I can give you some general information.
1. READ using the BINARY SEARCH addition.
This is indeed a good way of doing a READ. But have you made sure that the internal table is sorted by the required fields before you use this statement ?
2. LOOP...WHERE statement.
This is also a good way to avoid looping through unnecessary entries. But further improvement can certainly be achieved if you use FIELD-SYMBOLS.
LOOP AT ITAB INTO <FIELD_SYMBOL_OF_THE_SAME_LINE-TYPE_AS_ITAB>.
ENDLOOP.
3. PERFORM statements.
A perform statement can not be optimized. what matters is the code that you write inside the FORM (or a subroutine).
4. COLLECT statements.
I trust you have used the COLLECT statement to simplify the logic. Let that be as it is. The code is more readable and elegant.
The COLLECT statement is somewhat performance intensive. It takes more time with a normal internal table (STANDARD). See if you can use an internal table of type SORTED. Even better, you can use a HASHED internal table.
5. DELETE itab.(delete duplicates staements too)
If you are making sure that you are deleting several entries based on a condition, then this should be okay. You cannot avoid using the DELETE statement if your functionality requires you to do so.
Also, before deleting the DUPLICATES, ensure that the internal table is sorted.
6. SORT statement.
It depends on how many entries there are in the internal table. If you are using most of the above points on the same internal table, then it is better that you define your internal table to be of type SORTED. That way, inserting entries will take a little more time (to ensure that the table is always sorted), but alll the other operations are going to be much faster.
Get back to me if you need further assistance.

Hi Guys,
I have one internal table, I need to loop the table and READ the same table with in the loop.
My requirement is like this:
In the internal table KUNNR VKORG and VTWEG, if three fields values are same for more then one record, i need to append those records into another internal table.
Could any one help me.
Thanks,
Gourisankar

Hi,
Loop at itab1 into wa_tab1.
Read table itab1 into wa_tab2 with key kunnr = wa_tab1-kunnr
                                                          vkorg = wa_tab1-vkorg

create ur final internal table with the same data element as the fields of 1 and 2 itabs
and say move- corresponding to it_final..

Types defines the standard strcuture which you can use any where in the report.
it_jtab type standard table of it_itab.
As strcuture doesnot contain morethan one data, we declaring the internal using the strcuture which defined. The above statement is used to create a internal table without header line and the internal table type is of standard.

Regarding Internal Table Field Validation [Modification]

Hi All,
I have a small issue with formatting of a field.
The Field is POTX1 - it would get the value as 'New MT-EPPE0097-COMP02',
Means i have one internal table field as i_error-POTX1 in that some times we get value as 'New MT-EPPE0097-COMP02'.
Whenever i get 'New' literal in that internal table field i have to remove that literal from that internal table field. And Left Justify the remaining part of the field.
Ex: 'New MT-EPPE0097-COMP02'
     should become 'MT-EPPE0097-COMP02'.
For this first i have to find wether 'New' Literal exists in the Internal table field or not then i have to remove it.
Can anybody tell me how can i solve this issue.
Thanks in advance.
Thanks & Regards,
Rayeezuddin.

Hi,
Take a look :
loop at i_error.
if i_error-potx1(3) = 'New'
    w_potx1 = i_error-potx1.
    i_error-potx1 = w_potx1+3(37).
    MODIFY i_error.
endif.
ENDLOOP.

Regarding Internal Table Manipulation

Hi All,
I have a issue when working against Internal Table inside a function module.
Issue is:
My I.Table declaration is as below:
DATA: BEGIN OF i_vbfa_tab OCCURS 0.
 INCLUDE STRUCTURE vbfa.
DATA: END OF i_vbfa_tab.
Then in code i had written following logic:
SELECT VBELV
 VBELN
 VBTYP_N
 VBTYP_V
 FROM VBFA
 INTO ( V_VBELV, V_VBELN, V_VBTYP_N, V_VBTYP_V )
 WHERE VBELN = V_SO_ORDER2 AND
 VBTYP_N = 'G' AND
 STUFE = '00'.
IF SY-SUBRC EQ 0.
 I_VBFA_TABVBELN = V_VBELN.
 I_VBFA_TABVBELV = V_VBELV.
 I_VBFA_TABVBTYP_N = V_VBTYP_N.
 I_VBFA_TABVBTYP_V = V_VBTYP_V.
 APPEND I_VBFA_TAB.
 CLEAR I_VBFA_TAB.
ENDIF.
Then when i am checking for F2[Syntax] it is giving error as 'The Field I_VBFA_TAB-VBELN is unknown'. This is the case with all 4 assignment statements.
Can anybody tell me what is the issue over here.
What can i do to assign those values to internal table and append. I had tried with MOVE that is also giving same error.
Can anybody solve my issue.
Thanks in advance.
Thanks & Regards,
Prasad.

If you are doing something like:
call function 'Z_FUNC'
tables i_vbfa_tab = vbfa_tab.
and in the FM:
function z_func
*" TABLES
*" i_vbfa_tab STRUCTURE vbfa OPTIONAL
perform get_vbfa.
and then in an include
form get_vbfa
SELECT VBELV
VBELN
VBTYP_N
VBTYP_V
FROM VBFA
INTO ( V_VBELV, V_VBELN, V_VBTYP_N, V_VBTYP_V )
WHERE VBELN = V_SO_ORDER2 AND
VBTYP_N = 'G' AND
STUFE = '00'.
I think you'll get the syntax arror you describe. Try:
call function 'Z_FUNC'
tables i_vbfa_tab = vbfa_tab.
and in the FM:
function z_func
*" TABLES
*" i_vbfa_tab STRUCTURE vbfa OPTIONAL
perform get_vbfa
 tables i_vbfa_tab.
and then in the include
form get_vbfa
 tables i_vbfa structure vbfa.
data: v_vbelv like vbfa-vbelv,
 v_vbeln like vbfa-vbeln,
 v_VBTYP_N like vbfa-VBTYP_N,
 v_VBTYP_v like vbfa-VBTYP_v,
SELECT VBELV
VBELN
VBTYP_N
VBTYP_V
FROM VBFA
INTO ( V_VBELV, V_VBELN, V_VBTYP_N, V_VBTYP_V )
WHERE VBELN = V_SO_ORDER2 AND
VBTYP_N = 'G' AND
STUFE = '00'.
IF SY-SUBRC EQ 0.
I_VBFA_TABVBELN = V_VBELN.
I_VBFA_TABVBELV = V_VBELV.
I_VBFA_TABVBTYP_N = V_VBTYP_N.
I_VBFA_TABVBTYP_V = V_VBTYP_V.
APPEND I_VBFA_TAB.
CLEAR I_VBFA_TAB.
ENDIF.
I didn't test this, so if you use it, test it thoroughly.

Pls provide information regarding internal tables

hi
i would like to know can we create relationship between two internal tables.
like foriegn key relationship . if yes pls tell me how .

hi...
there is actual relationship that can b created for 2 internal tables using foreign keys,but by using " for all entries" in select statements.
syntax: for all entries.
TYPES: BEGIN OF ftab_type,
         carrid TYPE sflight-carrid,
         connid TYPE sflight-connid,

                 NON-UNIQUE DEFAULT KEY INITIAL SIZE 10,
       free TYPE I,
       wa_sflight TYPE sflight.
Suppose FTAB is filled as follows:
CARRID CONNID
LH      2415
SQ      0026
LH      0400
SELECT * FROM sflight INTO wa_sflight
    FOR ALL ENTRIES IN ftab

Regarding internal table

Hi ,
     i have an internal table
DATA: BEGIN OF tbl_infile OCCURS 0,
         Aufnr(12) type c,
         budat(8) TYPE c,
         tubes(13) type c,

         runmin(13) type c,
         stopmin(13) type c,
      END OF tbl_infile.
here the date from file comes into internal table as 140409 i want to change this to 14.04.2009 and place back into internal table how to change the internal table ?
Thanks in advance

Hi,
This is very simple:
1.Change the lenght of the budat from 8 to 10
2.either use the FM 'CONVERT_DATE_TO_EXTERNAL' to convert the date or
use the below snippet
3.Declare 3 local variable of type c each of lenght 2
data:var1(2) tyep c,
var2(2) tyep c,
var3(2) tyep c,
4.extract the dd,mm and yy using the offset from the budat
var1 = budat+0(2).
var2 = budat+2(2).
var3 = budat+4(2).
5.finally concatenate the above 3 variable into budat of internal table.
concatenate var1 '.' var2 '.' var3 into budat.
Hope this might solve your problem.

Regarding Internal table logic

Hi,
I have my internal table as follows:
DATA: BEGIN OF I_DATA OCCURS 0,
 prgname TYPE SYST-REPID,
 matnr TYPE mara-matnr,
 berid TYPE mdma-berid,
 END OF I_DATA.
Data that fills into can be as follows:
Ex:
PROGRAM1,1000,MRP1
PROGRAM1,1000,MRP1
PROGRAM1,2000,MRP1
PROGRAM2,1000,MRP1
PROGRAM2,1000,MRP1
PROGRAM2,2000,MRP1
PROGRAM3,1000,MRP1
PROGRAM3,1000,MRP1
PROGRAM3,2000,MRP1
It can any order in above way.
Then i will sort the above data as follows:
SORT I_DATA BY prgname matnr berid.
Now here my issue is:
DATA: t_objtxt LIKE solisti1 OCCURS 0 WITH HEADER LINE.
I need to push the above internal table data into T_OBJTXT internal table as follows:
It should first Display program Name as Program Name: Program3, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
When 2nd program comes again i have to write Program Name: Program2, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
When 3nd program comes again i have to write Program Name: Program3, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
Etc. Same process we need to follow.
The final out put should be as below:
PROGRAM NAME : PROGRAM1
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
PROGRAM NAME : PROGRAM2
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
PROGRAM NAME : PROGRAM3
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
Like wise o/p need to be send to I_OBJTXT and to email.
The logic i have written is as follows:
LOOP AT I__DATA.
 AT NEW PRGNAME.
 MOVE '*****************************************' TO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 CONCATENATE t_objtxt-line 'PROGRAM NAME : '

 MOVE '-----------------------------------------' TO t_objtxt-line.
 CONCATENATE t_objtxt-line '------------------' INTO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 ENDAT.
* MOVE '' TO t_objtxt-line.
* APPEND t_objtxt.
* CLEAR t_objtxt.
 CONCATENATE I_DATA-MATNR

 MOVE '' TO t_objtxt-line.
 APPEND t_objtxt.

 CONCATENATE t_objtxt-line '******************' INTO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 ENDAT.
ENDLOOP.
The above logic is not working correctly.
Can anybody give me correct logic for the same.
Thanks in advance.

Performance Issue When Read from Internal Table

In my form, I have 6 windows which contain all the header information, which are kept in my gt_header internal table. Since all windows required data from the same internal table, reading the internal table at Initialization for once or, creating the LOOP at each window, which one will be a better choice in terms of performance?

Hi,
you cannot create 6 windows under loop.You can only have loop under a window only.
So create a big window which covers whole area of 6 windows.Create templete under that and write only one loo with text in all those boxes of that templete.

Using internal tables in BI 7 Start routines

Hi All
I tried searching for using internal tables in a start routine in BI 7 could not find the right pointers.
This is what I am trying to do is the following:
In a DSO ZSD_O01 I have a sales order and sales order item number and this DSO also contains the Contract number and the contract Item number.
The DSO structure is as follows:
/BIC/AZSD_O0100
DOC_NUMBER
ITEM
CONTRACT
CITEMNUM
I want to read the data in this DSO into a internal table. But the key fields in this DSO is DOC_NUMBER and ITEM so I want to read this data into a internal table only for the first data package into the internal table. Thereafter I want to lookup into the internal table given the doc_number and ITEM to find the CONTRACT and CITEMNUM.
Can any of you kindly show me how to :
- Read data from a DSO into a internal table
- Read the internal table for the first data package
- How do I make the access in the internal table fast when my lookup in the internal table is not on the
DSO key columns but on a different key column
Appreciate your help
Thanks
Karen

Hi Karen ,
It will be helpful if you tell your requirement as the approach you suggested is not looks convincing .May be their is some easy way and we can suggest you better approach
-how to check for source_package = 1
You need to hard code it .
We decide package size at DTP level so you can declare a global variable .let say you have 50000 size of your package then use global variable as counter and read only when record_count is <= 50000 .
-how to declare the internal table so the values in it exists between different data packages
Declare a global table and select data into it .A global table retain data across the packages .
- The key on which I need to lookup in the internal table is not the key fields as in the DSO
Its ok .Let say you are doing lookup on A B and C field of DSO1 and the values may duplicate in your source .then you just need to read the internal table having data from DSO2 with key field A B C .
Better if you set them as semantic keys at DTP level so that all duplicate entries of A B C will appear in same package .
global Declarations
In your start routine you will have this following code :
TYPES:
 tyt_SC_1 TYPE STANDARD TABLE OF tys_SC_1
 WITH NON-UNIQUE DEFAULT KEY.
$$ begin of global - insert your declaration only below this line -
... insert your code here
$$ end of global - insert your declaration only before this line -
One question
Why you want to populate values for 1 source package only not for all ?This will be helpful to understand your requirement and may be we can fulfill it in some other manner .
