OCCURS clause

WE know that the OCCURS clause in the internal table statement creates the internal table object
In the following statement is this possible:-
TYPES <mt> TYPE| LIKE <linetype> OCCURS<n> .
If not what else?

Hi abaper learner,
The OCCURs Clause is used for declaring the SIZE of the Internal Table..
For EG:
Data: begin of itab occurs 0, means this will create an internal table with 8KB of memory.
But if you are specifrying
data:begin of itab occurs 10, this will create an internal table with 10 rows(according to the structure of the internal table)...
Kindly Reward points if you found the reply helpful.
Cheers,
CHAITANYA.

What will happen if we dont give occurs clause while creating an inttable?

hi
experts can u help me pzzzzzzzzzzzzz

hi
work area wont be created.
table is created without header line
the OCCURS clause also defines how many table entries are maintained in main storage. Extra records are written out to paging area and can effect performance.
EXAMPLE:
TYPES : begin of line,
 empno type I,
 empname(20) type c ,
 end of line.
By using DATA statement we need to create internal table by referring to TYPES data type.
hope it clears ur doubt

I am facing performance issue in a report due to addition of occurs clause

Hi,
I am facing performance in one program. I think while declaring internal table used OCCURS 100 but records are populating 470840 no of records.
again in 2nd internal table declared OCCURS 10 but records are entering 18 no of records.
I guess because of this program is taking nearly 30 mins time and not getting correct out put.
I am not sure weather this is the reason.
So any one can give proper suggestion to improve the performance of the program
in the internal table t_dels_tvpod showing the no of records in debugging = 470840 * 9(80)
in the internal table lt_dels_tvpod showing the no of records in debugging = 18 * 9(80)
I have shown the part of the program code.
Program code
DATA:   BEGIN OF t_dels_tvpod OCCURS 100,
          vbeln LIKE tvpod-vbeln,
          posnr LIKE tvpod-posnr,
          lfimg_diff LIKE tvpod-lfimg_diff,
          calcu LIKE tvpod-calcu,
          podmg LIKE tvpod-podmg,
          uecha LIKE lips-uecha,
          pstyv LIKE lips-pstyv,
          xchar LIKE lips-xchar,
          grund LIKE tvpod-grund,
        END OF t_dels_tvpod,
DATA: l_tabix LIKE sy-tabix,
        lt_dels_tvpod LIKE t_dels_tvpod OCCURS 10 WITH HEADER LINE,
        ls_dels_tvpod LIKE t_dels_tvpod.
SELECT vbeln INTO TABLE lt_dels_tvpod FROM likp
         FOR ALL ENTRIES IN t_dels_tvpod
         WHERE vbeln = t_dels_tvpod-vbeln
         AND   erdat IN s_erdat
         AND   bldat IN s_bldat
         AND   podat IN s_podat
         AND   ernam IN s_ernam
         AND   kunnr IN s_kunnr
         AND   vkorg IN s_vkorg
         AND   vstel IN s_vstel
         AND   lfart NOT IN r_del_types_exclude.
Waiting for quick response.

You should declare your structure with TYPES statement and with this type declare internal table.
Example:
types: begin of ty_itb,
           budat type budat,
           matnr type matnr,
           end of ty_itab.
data: itab type standard table of ty_itb,
        wa_itab like line of itab. (work area of itab)
Since both occurs and header line statements are obsolete.
change the below select query as follows can improve the performence
if not IN t_dels_tvpod[] is initial. (always check this, if you are using For all entries statement)
SELECT vbeln lfart INTO TABLE lt_dels_tvpod FROM likp
FOR ALL ENTRIES IN t_dels_tvpod
WHERE vbeln = t_dels_tvpod-vbeln
AND erdat IN s_erdat
AND bldat IN s_bldat
AND podat IN s_podat
AND ernam IN s_ernam
AND kunnr IN s_kunnr
AND vkorg IN s_vkorg
AND vstel IN s_vstel.
endif.
delete lt_dels_tvpod where lfart not in r_del_types_exclude.

Occurs

what does it mean occurs 0 while creating an internal table and what wil happen if we wil not give occurs clause while creating an internal table?

hai,
occurs 0 is allocating the 2kb of memory space in RAM defaultly.
thats why we are using this but now a days we wont prefer this bcose it wont supports opps concepts.

Diff between occurs 0 and occurs 3

in internal table why should we mention occurs clause...with out header line...its giving error..

Hi,
Occurs does not limit the number of rows that can be added to the internal table. For example if you specify occurs 10, you can put upto 10 rows into internal table.The number of rows you can put into an internal table is theoritically only limited by the amount of virtual momory available on the application server.
The system uses the occurs clause only as a guidlines to determine how much memory to allocate. The first time a row is added to the internal table, enough memory is allocated to hold the number of rows specified on the occurs clause. If you use the memory up, more is allocated as needed.
Alternatively, you can specify occurs 0. If you do this, the system allocated 8KB pages of memory at a time. However there are no advantages to using occurs 0 other than the fact it is only a litter easier to code occurs 0 than it is to estimate the size of the internal table
For peak performace and minimum wasted momery, choose as occurs value equal to the average maximum number of rows in the table. For Example if most of the time the internal table is filled with a maximum of 100 rows, but every once in a while it is filled with a maximum of 1000 rows, set the occurs value 100.

Short dump-internal table size issue

Hi,
I get the following message in the short dump analysis for a report.
No storage space available for extending table "IT_920".
You attempted to extend an internal table, but the required space was not available.
Error Analysis:
The internal table "IT_920" could not be enlarged further.
To extend the internal table, 9696 bytes of storage space was
needed, but none was available. At this point, the table "IT_920" has
1008240 entries.
Its an old report and I saw the internal table declaration using the "OCCURS" clause in the internal table declaration.
begin of itab occurs 100.
end of itab.
I tried the option of changing to "OCCURS 0", still issue persists.
Any help would be highly appretiated

Hello CMV,
This is basic problem with SAP internal tables. For every internal table memory is alocated ( Max..256K)...once you cross the memory size/limit of the internal table it resuls in short dump.
Only way to overcome this problem is handle limited number of records at a time..
Please refer following sample code which will help you to avoid short dump while processing large number of records....
SORT TAB_RESULT.
DESCRIBE TABLE TAB_RESULT LINES W_RECORDS.
W_LOW = 1.
W_UP = 1000.
*Spliting the records from tab_result1 by pakage of 1000 at a time
*to avoid short dump in case of more records
WHILE W_LOW <= W_RECORDS.
 R_PKUNWE-SIGN = 'I'.
 R_PKUNWE-OPTION = 'EQ'.
 R_WERKS-SIGN = 'I'.
 R_WERKS-OPTION = 'EQ'.
 LOOP AT TAB_RESULT FROM W_LOW TO W_UP.
 MOVE TAB_RESULT-PKUNWE TO R_PKUNWE-LOW.
 MOVE TAB_RESULT-WERKS TO R_WERKS-LOW.
 APPEND R_PKUNWE.
 APPEND R_WERKS.
 ENDLOOP.
*fetch sold to party
 SELECT KUNNR NAME1
 FROM KNA1
 APPENDING CORRESPONDING FIELDS OF TABLE TAB_KNA1
 WHERE KUNNR IN R_PKUNWE.
*fetch plant
SELECT WERKS NAME1
 FROM T001W
 APPENDING CORRESPONDING FIELDS OF TABLE TAB_T001W
 WHERE WERKS IN R_WERKS.
 REFRESH: R_PKUNWE,
 R_WERKS.
 W_LOW = W_LOW + 1000.
 W_UP = W_UP + 1000.
ENDWHILE.
Hope this will help you to solve problem.

Hi Mahesh,
Very good questions. Infact it's very difficult to answer all the questions.
You can search many FAQs in net...
If you have any specific questions related to single topic, Post message for each.
I can send some of FAQ documents to u
Answers
1) Using Index like Field(1)-1st record field , Field(2) - 2nd record field etc... in Table control.. we can handle BDC
2) BAPI will be programmed using OO concepts more.. and as Interfacing is more enhanced here than normal FM.
etc...

To make a smartform report efficient by removing all occurs & modify internal table statements.
What i have been given to do is to select all data from respective tables put them into one internal table & then finally making tab2 or tab3 in the report to be the final table.I am not sure which among these two i can make final table.
THE CODE is:
REPORT zgr_note.

Hello Saswat,
There are a couple of criteria to make a SmartForm report efficient, i.e. to achieve a better performance:
- provide the best possible interface to the temporary FM (fname). When you do so, SmartForm itself has not to perform so much programming stuff by itself.
- The Driver program (zgr_note) has to be designed and coded well. What mean the performance of the Driver has to be optimized. In your case there should be a couple of performance improvements:
-- adjust your program declaration to the new ABAP syntax, i.e. don't use OCCURS clauses and do not use HEADER LINE. Instead, implement TYPES and use them. Here is an example:
TYPES: BEGIN OF ty_itab.
 INCLUDE STRUCTURE mseg.
TYPES: post1 LIKE proj-post1, "Project Definition
 pspnr LIKE proj-pspnr, "WBS element
 maktx LIKE makt-maktx, "Material Description
 name1 LIKE lfa1-name1, "Name of the supplier
 budat LIKE mkpf-budat, "Posting date
 bldat LIKE mkpf-bldat, "Document date
 cpudt LIKE mkpf-cpudt, "Date on which account document was entered
 psphi LIKE prps-psphi, "Current number of project
 post2 LIKE prps-post1, "WBS Definition
 xblnr LIKE mkpf-xblnr, "Reference number( in this case challan number)
 bktxt LIKE mkpf-bktxt, "Header text
 ort01 LIKE lfa1-ort01, "vendor city
 ktext LIKE aufk-ktext, "network description
 ltxa1 LIKE afvc-ltxa1, "operation short text
 END OF ty_itab.
* Declare your internal tables and the corresponding working structures
DATA: itab1 type standard table of ty_itab,
 itab2 type standard table of ty_itab,
 itab3 type standard table of ty_itab,
 jtab type standard table of ty_itab,
 wa_itab1 type ty_itab,
 wa_itab2 type ty_itab,
 wa_itab3 type ty_itab,
 wa_jtab type ty_itab.
-- Don't use
LOOP at itab.
SELECT ...... WHERE pspnr = itab-ps_psp_pnr.
ENDSELECT.
SELECT * ...
ENDSELECT
SELECT * .....
ENDSELECT
ENDLOOP.
Instead try to populate itab, itab1, itab2 each in ONE select statement using FOR ALL ENTRIES clause. After that you have to perform the LOOP runs using LOOP at itab INTO wa_itab. The more redundant SELECTs, the slower the program! When you perform a LOOP run, let say over itab1 and you need a corresponding record from table itab2 the use READ <itab> with key.
One additional, very important hint: Using internal tables w/o header line the CLEAR statement has another functionality than with HEADER LINE
CLEAR with HEADER LINE clears the HEADER line only
CLEAR w/o HEADER LINE clears the entire table. CLEAR does the same as REFRESH.
Another performance improvement is (when itab contains a lot of records) using FIELD-SYMBOLS.
A simple example is
FIELD-SYMBOLS: <fs> type itab.
LOOP at itab assigning <fs>.
wa_itab3-post1 = <fs>-post1.
wa_itab3-post2 = <fs>-post2.
APPEND wa_itab3 to itab.
ENDLOOP.
In this case no data values have to be transfered to a working field. The values are taken directly from the current line of the internal table.
-- For better readability disign some events like START-OF-SELECTION, END-OF-SELECTION, INITIALIZATION and others.
Try to gather all in SmartForms needed fields and pop them into table itab3.
I hope this helps improving zgr_note's efficiency.
Good luck,
Heinz

Internal table with same variable and one select query

Hi,
I am a new bee here with may be a silly question.
I have a internal table as below.
DATA: BEGIN OF IT_ORDERDETAILS OCCURS 0,
 VBELN LIKE VBAK-VBELN, "Order number
 BSTNK LIKE VBAK-BSTNK, "customer PO
 ERDAT LIKE VBAK-ERDAT, " Order created date
 MATNR LIKE VBAP-MATNR, "Sales order line item
 KWMENG LIKE VBAP-KWMENG, "Quantity
 D_VBELN like likp-vbeln, " delivery no
 POSNR like lips-posnr, " delivery item
 KUNNR LIKE LIKP-KUNNR, "ship quantity
END OF IT_ORDERDETAILS.
Where VBELN field is in VBAK and LIKP table.
VBELN in VBAK table = order #
VBELN in LIKP table is = Delivery #
I want to use join to fetch data in single select query.
Below is the select query
SELECT VBAK~VBELN
 VBAK~BSTNK
 VBAK~ERDAT
 VBAP~MATNR
 VBAP~KWMENG
 likp~vbeln
 lips~posnr
 LIPS~VGBEL
 INTO (IT_ORDERDETAILSvbak, IT_ORDERDETAILSbstnk, IT_ORDERDETAILSerdat, IT_ORDERDETAILSmatnr, IT_ORDERDETAILSkwmeng, IT_ORDERDETAILSd_vbeln,IT_ORDERDETAILSposnr, IT_ORDERDETAILSkunnr)
FROM VBAK left outer JOIN VBAP ON ( VBAKVBELN = VBAPVBELN )
left outer JOIN LIPS ON ( VBAKVBELN = LIPSVGBEL )
join LIKP on ( LIPSVBELN = LIKPVBELN )
WHERE VBAK~ERDAT IN CR_DATE.
I am getting error in the query.
Please suggest.
Thanks,
Rajesh

Hi rajesh.nayakbola,
although this is not quite the right place for this, let me give you some notes:
1. Code should be
formatted as code
by markin it with mouse and use above <> button.
2. Internal tables shoult not be declared using OCCURS clause - this is last century style
3. Internal tables do not need and should not have a header line, they should use TYPES for declaration
4. Data should not be declared using LIKE: If they refer to dictionary TYPES, use TYPE. LIKE is only mandatory for data objects declared in your program, i.e. DATA IT_some_ORDERDETAILS like IT_ORDERDETAILS.
5. If you get an error here, never write "I am getting error" but copy and paste the error message fully.
- The fields in brackets in the INTO clause never have ~ character, there is no IT_ORDERDETAILS~vbak, only IT_ORDERDETAILS-vbeln
It could be something like this:
TYPES:
BEGIN OF TY_ORDERDETAILS,
VBELN TYPE VBAK-VBELN, "Order number
BSTNK TYPE VBAK-BSTNK, "customer PO
ERDAT TYPE VBAK-ERDAT, " Order created date
MATNR TYPE VBAP-MATNR, "Sales order line item
KWMENG TYPE VBAP-KWMENG, "Quantity
D_VBELN TYPE likp-vbeln, " delivery no
POSNR TYPE lips-posnr, " delivery item
KUNNR TYPE LIKP-KUNNR, "ship quantity
END OF TY_ORDERDETAILS.
DATA:
IT_ORDERDETAILS TYPE TABLE OF TY_ORDERDETAILS.
SELECT VBAK~VBELN
VBAK~BSTNK
VBAK~ERDAT
VBAP~MATNR
VBAP~KWMENG
likp~vbeln AS D_VBELN
lips~posnr
LIKP~KUNNR
INTO CORRSPONDING FIELDS OF TABLE IT_ORDERDETAILS
FROM VBAK left outer JOIN VBAP ON ( VBAK~VBELN = VBAP~VBELN )
left outer JOIN LIPS ON ( VBAK~VBELN = LIPS~VGBEL )
join LIKP on ( LIPS~VBELN = LIKP~VBELN )
WHERE VBAK~ERDAT IN CR_DATE.

How to dynamicly create a field name AND access it

All,
I am trying to build a code block that will access what amounts to a table structure inside a table. I have 38 occurances if a set of 3 fields. (Source system had an internal array/occurs clause that was converted for our ODS into individual fields) I am returning a single row as a row type and have addressability to all fields. What I am trying to avoid is coding my logic block 38 times, 1 for each occurance.
FOR X IN 1 .. 38 LOOP
V_CAT_CD_X := 'CAT_'||X||'_CD';
End Loop;
The following is the display of the correctly built field:
--> Loop Cat CD: CAT_1_CD Rec count:1 Loop counter:1
--> Loop Cat CD: CAT_2_CD Rec count:1 Loop counter:2
--> Loop Cat CD: CAT_3_CD Rec count:1 Loop counter:3
--> Loop Cat CD: CAT_4_CD Rec count:1 Loop counter:4
My problem is that my row cursor PP1 is addressable hardcoding PP1.CAT_1_CD or PP1.CAT_2_CD ect, however I am having problems using my created string to access the field.
What do I need to do to gain accessability via this method?
I do have the ability to select the column names from the system tables but even then, I am lacking addressability to my ROW type using the selected field name.
Thanks
Greg

A program analysis begins at the first statement which is right after the last DATA declaration. For maintenance purposes this statement appears after the first EVENT. Such an EVENT can be e.g. START-OF-SELECTION, INITIALIZATION, AT USER-COMMAND etc.
In your thread only data declarations are shown. These declarations can be improved (for further performance issues) as well. All the table declarations should adhere the modern ABAP syntax, what means you should omit the obsolete OCCURS clause!
E.g.
DATA : BEGIN OF MBEWTEMP OCCURS 10,
MATNR LIKE MBEW-MATNR,
VERPR LIKE MBEW-VERPR,
ZPLP1 LIKE MBEW-ZPLP1,
ZPLP2 LIKE MBEW-ZPLP2,
ZPLP3 LIKE MBEW-ZPLP3,
END OF MBEWTEMP.
should be replaced by something like
TYPES: BEGIN OF TY_MBEWTEMP,
MATNR LIKE MBEW-MATNR,
VERPR LIKE MBEW-VERPR,
ZPLP1 LIKE MBEW-ZPLP1,
ZPLP2 LIKE MBEW-ZPLP2,
ZPLP3 LIKE MBEW-ZPLP3,
END OF TY_MBEWTEMP.
DATA: MBEWTEMP TYPE TABLE OF TY_MBEWTEMP,
 WA_MBEWTEMP TYPE TY_MBEWTEMP.
FIELD-SYMBOLS: <fs> TYPE TY_MBEWTEMP.
To achieve a better performance in your LOOP runs, the designed LOOP should look like:
LOOP AT MBEWTEMP into assigning <fs>. "or into wa_mbewtemp
MOVE <fs>-MATNR to <somewhere>.
ENDLOOP.
Header lines shouldn't be used anymore. Using the assign clause, there is no additional data space needed. <fs> points directly to the current index in the internal table.
The most critical areas for a proper performance are the LOOP runs, the SQL statements (prevent selects in a LOOP!!) and data uploads from either a presentation server or an application server.
Hope this helps,
Heinz

Smartform performance issue

HI floks
i did some development in new smartform its working fine but i have issue in data base performance is 76% . but i utilize similar below code with various conditions in various 12 places . is it possible to reduce performance this type of code . check it and mail me how can i do it . if possible can suggest me fast .how much % is best for this type of performance issues.
DATA : BEGIN OF ITVBRPC OCCURS 0,
       LV_POSNR LIKE VBRP-POSNR,
       END OF ITVBRPC.
DATA : BEGIN OF ITKONVC OCCURS 0,
        LV_KNUMH LIKE KONV-KNUMH,
        LV_KSCHL LIKE KONV-KSCHL,
       END OF ITKONVC.
DATA: BEGIN OF ITKONHC OCCURS 0,
       LV_KNUMH LIKE KONH-KNUMH,
       LV_KSCHL LIKE KONH-KSCHL,
       LV_KZUST LIKE KONH-KZUST,
       END OF ITKONHC.
DATA: BEGIN OF ITKONVC1 OCCURS 0,
       LV_KWERT LIKE KONV-KWERT,
       END OF ITKONVC1.
DATA : BEGIN OF ITCALCC OCCURS 0,
       LV_KWERT LIKE KONV-KWERT,
       END OF ITCALCC.
DATA: COUNTC(3) TYPE n,
       TOTALC LIKE KONV-KWERT.
SELECT POSNR FROM VBRP INTO ITVBRPC
WHERE VBELN = INV_HEADER-VBELN AND ARKTX = WA_INVDATA-ARKTX .
APPEND ITVBRPC.
ENDSELECT.
LOOP AT ITVBRPC.
SELECT KNUMH KSCHL FROM KONV INTO ITKONVC WHERE KNUMV =
LV_VBRK-KNUMV AND KPOSN = ITVBRPC-LV_POSNR AND KSCHL = 'ZLAC'.
APPEND ITKONVC.
ENDSELECT.
ENDLOOP.
SORT ITKONVC BY LV_KNUMH.
DELETE ADJACENT DUPLICATES FROM ITKONVC.
LOOP AT ITKONVC.
SELECT KNUMH KSCHL KZUST FROM KONH INTO ITKONHC WHERE KNUMH = ITKONVC-LV_KNUMH AND KSCHL = 'ZLAC' AND KZUST = 'Z02'.
APPEND ITKONHC.
ENDSELECT.
ENDLOOP.
LOOP AT ITKONHC.
SELECT KWERT FROM KONV INTO ITKONVC1 WHERE KNUMH = ITKONHC-LV_KNUMH AND
KSCHL = ITKONHC-LV_KSCHL AND KNUMV = LV_VBRK-KNUMV.
MOVE ITKONVC1-LV_KWERT TO ITCALCC-LV_KWERT.
APPEND ITCALCC.
ENDSELECT.
endloop.
LOOP AT ITCALCC.
COUNTC = COUNTC + 1.
TOTALC = TOTALC + ITCALCC-LV_KWERT.
ENDLOOP.
MOVE ITKONHC-LV_KSCHL TO LV_CKSCHL.
MOVE TOTALC TO LV_CKWERT.
it's urgent ..........
thanks .

Hi,
you can increase the performance by following,
1. By changing occurs clause to types declaration clause.
   You need to declare like this:
   DATA : BEGIN OF xVBRPC,
                  LV_POSNR LIKE VBRP-POSNR,
              END OF xVBRPC.
   DATA: ITVBRPC like table of xVBRPC,
2. do not use select statements in loop statements.

Basic doubt about ITAB

Dear All,
techinicallly is there any difference between.
data : it_mara type standard table of mara.
t_mara type mara occurs 0.
Which is better way to define. I know both are internal tables without header.
onemore thing, header that it is obsolete to use "occurs 0", is this right.
Please let me know.
Regards
madhu

Hi,
Yes...you should use only table declarations without the occurs clause. This improves performance a lot. And this kind of declarations has become mandatory with the ECC6.0 release.
Try practicing to declare without the occurs clause.
Thanks,
Subramanian
