Check an internal table is initial or not..

Hello experts,
I need to check whether an internal table is initial or not in AMDP.....
Lets say i have an internal table IT_TAB[].
I need a statement similar to IT_TAB[] IS NOT INITIAL (in ABAP)
I already tried with COUNT(*), but it returns me an internal table with a column name COUNT with the total number of entries and found it not useful.
Thanks in Advance,
Ramesh

Well do it by below way.
DECLARE LV_LINE VARCHAR(3);
SELECT COUNT(*) INTO LV_LINE FROM :IT_TAB;

I need to add check whether 21 fields of a internal table are empty or not.

Hello,
I need to add check whether 21 fields of a internal table are empty or not.How can we write a code for the same wand what would be the correct syntax for it.
I tried entering all the fields in the IF loop with AND condition but its giving syntax error.Perhaps this is because the lenght of the IF condition would be more than the allowed one.

Hi,
After the select quiery.
If not itab is initial.
Message 'Table is not empty' type 'I'.
Endif.

How to check if internal table exists in dynamical called subroutine ?

Hi,
in a dynamically called subroutine i'm using a internal table, but in some calls this table is not exist.
How can i check in the code whether the internal table exist or not ?
regards,
Hans

In Horst Keller's blog /people/horst.keller/blog/2005/05/27/abap-geek-10--everything-functions-150-but-how my issue is talked about :
All other parameters are handled in a way as they were declared as global data objects in the top include of the function group, that can be used only during the execution of the function module: They are visible throughout the function group but you can access them only while the function module is active. If you access such a parameter and the respective function module is not executed, you get the runtime error GETWA_NOT_ASSIGNED (Why? Well, technically thos guys are represented via field symbols which are valid only during the runtime of the function module).
The code is in SD pricing. Sometimes the code is called from function module PRICING_BUILD_XKOMV or PRICING_SUBSCREEN_PBO where TKOMV is defined as globalized parameter.
And sometimes it is called from function module PRCING_CHECK where TKOMV is NOT defined as parameter.
In the call of last function the dump occures on the ASSIGN statement :
     data: ls_tkomv like line of tkomv,
              lv_tablename(30) type c value 'TKOMV[]'.
    field-symbols: <lfs> type any table.
     assign (lv_tablename) to <lfs>.
     if <lfs> is assigned.
Any suggestions to solve the issue ?

Hans

How to check if date field is initial or not in script layout?

How to Check whether a table is indexed or not?

Hi all,
I am writing a c++ program where i have to create an Index if Index not exists.
Oracle 10.2 is the oracle version and i am using oracle text for indexing.
table -- create table xmltable (versionnumber number,instance xmltype);
index -- create index configindex on xmltable (instance) indextype is ctxsys.context;
drop -- drop index configindex force;
My algorithm should something like,
if(configindex is exists)---------->What i have to write here to check if index is present.
{ drop index configindex force; }
create index configindex on xmltable (instance) indextype is ctxsys.context;
Thanks......

Hi,
You could check the system view ALL_INDEXES .

Internal table content not retained in statefull BSP application.

Hi Forum,
I have a statefull BSP application with two pages.I fill an internal table ITAB in the OnInputProcessing eventhandler of first page and then transfer this ITAB to second page , but when i navigate back from second page to first page , the internal table ITAB is cleared.I need the data in ITAB when i come back to first page.
The internal tables that i fill in the OnCreate eventhandler of the first page are intact but this ITAB that i fill in OnInputProcessing is cleared.
I tried using
runtime->keep_context = 1.
but it is not helping either...and i have checked the code carefully to ensure that ITAB is not cleared anywhere using CLEAR ITAB.
ITAB is declared in PAGE ATTRIBUTES using a tabletype.
What might be the problem?
Thanks,
Anubhav.

Hi Heth,
I carried out a small test application as follwos:
1)Filled an internal table ITAB_ZSCMG in OnCreate event of first page.
2)Filled an internal table ITAB_MATERIALS in OnInputProcessing for the OnClick of button event.
When my application was stateless the internal table ITAB_ZSCMG was initial in the OnInputProcessing event .
When i switched to STATEFULL mode , it contained data in the OnInputProcessing .
3)Crearted one more page SECOND.HTM.
4)in the OnClick event for button in OnInputProcessing eventhandler i navigated back to FIRST.HTM .
Found that all the internal tables were initial , although my page was statefull.
All these ITABs were declared using Page Attributes.
So i guess , a statefull application just means that DATA is retained between different eventhandlers of the SAME PAGE and not if we navigate from that page....
Hence in my case i have to transfer the ITAB back to first page again using SERVER SIDE COOKIES..
Please correct me if my derivations are wrong!!!
But the question still remains....
How to retain data after navigation?
Do we have a solution in BSP or we need to use SET/GET or EXPORT/IMPORT or COOKIES?
Thanks,
Anubhav.

Data is not coming in internal table

Hello Abapers,
Data is not coming in my internal table.
Plz tell me where I m wrong

Ravi

Hi,
write ur query this way :
SELECT avbeln afkart aknumv afkdat abelnr aktgrd abukrs axblnr amwsbk bgsber bwerks bktgrm
FROM ( vbrk AS a INNER JOIN vbrp AS b ON
avbeln EQ bvbeln )
INTO CORRESPONDING FIELDS OF TABLE vbrk_vbrp
WHERE ( a~fkart EQ billtype ) AND
( a~fkdat IN billdate ) AND
( a~ktgrd EQ acgrpc ) AND
( a~bukrs EQ compcode ) AND
( b~gsber IN bussarea ) and
( b~werks IN plant ) AND
( b~ktgrm EQ acgrpm ) .
even plz check then internal table ' vbrk_vbrp ' if they have all the fields of select query and even the order is same as select , since you are using ' into corresponding fields of table ' clause in select statement.
hope this helps.
thanx,
dhanashri.

So i need to check whther it is in sequence if not so i should delete the record
Could you suggest the way to check the in_tab?
Regards
senthil

Hi,
Try the follwoing:
You just need to use AT NEW control break after the loop statement.
DATA: Var1(5)    TYPE n.
DATA: Var2(5)    TYPE n.
DATA: Count(5) TYPE n.
DATA: it_tab2     type table of it_tab.
clear: count.
LOOP at it_tab.
AT NEW a
Clear: count, Var1, Var2.
Count = Count + 1.
IF Count >= 2.
var2 = it_tab-D.
If var2 = var1 + 1.
append it_tab to it_tab2.
endif.
endif.
var1 = it_tab-D.
ENDAT
Endloop.

Best way to check if table is empty or not

Hi. I had to check if a table was empty or not, and found different solutions.
One of them called my atention, I readed it was the best way to do it (some 'dual' trick from Steven Feuerstein, they say) :
SELECT 1 FROM DUAL WHERE EXISTS (SELECT 'X' FROM TABLE);
Plan
SELECT STATEMENT ALL_ROWSCost: 4 Cardinality: 1
     3 FILTER
          1 FAST DUAL Cost: 2 Cardinality: 1
          2 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
But doing some tests I found this query to have lower cost:
SELECT 1 FROM TABLE WHERE ROWNUM=1;
Plan
SELECT STATEMENT ALL_ROWSCost: 2 Cardinality: 1
     2 COUNT STOPKEY
          1 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
So, what about that dual table trick? Should I keep the 'select 1 where rownum=1' as best possible way?
I know it shouldn't matter much, but just wanna know what method works best for checking empty tables :)
Thanks.

As already mentioned, you cannot just base it on cost, as the cost is not specifically a good indicator of the amount of work that will need to be done, it's just an internal figure calculated for that query and isn't really that comparible across different queries.
If you're intending to see if there is data in a table because you want to know whether to query it or not, you are actually better to just try and query the data and capture the NO_DATA_FOUND exception and handle that. In that case it requires no effort or cost up front.

New Line after every 900 lines in internal table

HI,
I have an internal table and that is sorted by company code. i.e it is grouped according to company code.
Now i want to check in particular groups of company code if the lines of internal table is > 900 or not.
And if it > 900 i have to insert new line.
How to do that?

Hi
Please check the code..I think it will solve ur problem
TYPES : BEGIN OF x_data,
         name TYPE char10,
        END OF x_data.
data: i_data TYPE STANDARD TABLE OF x_data INITIAL SIZE 0,
      wa_data TYPE x_data,
      counter TYPE n LENGTH 2 .
DO 5 TIMES.
CLEAR : wa_data.
counter = counter + 1.
CONCATENATE 'subha' counter INTO wa_data-name.
APPEND wa_data to i_data.
ENDDO.
CLEAR : counter,
        wa_data .
DESCRIBE TABLE i_data LINES counter.
IF counter > 4.
counter = 5.
wa_data-name = 'TEST'.
INSERT wa_data INTO i_data INDEX counter.
ENDIF.
CLEAR: wa_data.
LOOP at i_data INTO wa_data .
WRITE : / wa_data-name.
ENDLOOP.
Use 900 instead 4 and 901 instead of 5.
