For all entries in itab.....

Hi experts..
i hv select query which looks like this...
select field1 field2 into (itab-field1, itab-field2) from dbtab1
where field1 in s_field1.
The problem is i hv to add another code
"for all entries in itab2
where field2 = itab2-field2"
to this select query..
please advice how i can do this.....
Thanks in advance..
-Pranati..

Hi,
In the following piece of code,
select field1 field2 into (itab-field1, itab-field2) from dbtab1
for all entries in itab2
where field1 in s_field1
and field2 = itab2-field2.
change this to:
data: begin of itab1 occurs 0,
          field1 like dbtab1-field1,
          field2 like dbtab1-field2,
       end of itab1.
select field1 field2 into table itab1 from dbtab1
for all entries in itab2
where field1 in s_field1
and field2 = itab2-field2.
Hope this works.

Does 'For All Entries in itab' work exactly like 'Join' statement?

Hi,
I would like to know that if 'For All Entries in itab' work exactly like 'Join' statement?
If yes, then when I use 'For All Entries in itab' and a 'Join' statement seperately with the same logical conditions for both, the number of records returned by the two methods are not same. Ideally, they should both return the same number of recs.
Can somebody help?
With regards.

Hi,
for all entries will not work in the same way unless untill it should satisfy some conditions,
it has some pre-requisests...
like in the select clause or in where clause or in both the cluases, there should be entire key..
then only it will behave like the join statement..
hope i am clear.
please revert back if u have any quiries.

Error - for all entries in itab

Hello guys !!!
I have the following select queries....
select * from vbrp into table itab.
select * from vbpa into table i_vbpa for all entries in itab
where VBELN = itab-vbeln and ( PARVW = 'Z2' or PARVW = 'Z3').
select belnr awkey from bkpf into table i_bkpf2 for all entries in itab where xblnr = itab-vbeln.
I get the following error in 3rd select query.....
When you use the addition "FOR ALL ENTRIES IN itab", the fields "XBLNR"
and "ITAB-VBELN" must have the same type and the same length.
But if i try to change the data type of the field ITAB-VBELN to - " VBELN(16) TYPE C " then i get the following error....
When you use the addition "FOR ALL ENTRIES IN itab", the fields "VBELN"
and "ITAB-VBELN" must have the same type and the same length.
How to i solve this problem ?????

Hi,
This is because XBLNR is 16 char length and VBELN is of 10.
So before passing itab to 3 query;
select belnr awkey from bkpf into table i_bkpf2 for all entries in itab where xblnr = itab-vbeln.
Create an intermediate itab with structure of vbeln with length 16 and transfer all data to this itab.
Then do as;
select belnr awkey from bkpf into table i_bkpf2 for all entries in itab where xblnr = itab1-vbeln.
Since you are using only vbeln in for all entries its even enough for the intermediate itab to have only one field to hold the values of VBELN. But you should add leading zeroes( by CONVERSION_EXIT_ALPHA_INPUT) before passing it in the query.

"For All Entries in ITAB" -error

Hello!
                   I am new to this ABAP. I getting one error in Select query "For All Entries" keyword. My problem is,
        Iam taking vbeln field from the table LIPS and stored in internal table it_lips. and then based on this vbeln i am taking the material document no. field mblnr from MKPF table. The Common field present in this table is vbeln in LIPS and xblnr in MKPF.
my select query is,
                              select xblnr mblnr
        into corresponding fields of table it_mkpf
        from mkpf

which one will get better performce.
and
if ipre table have a lot of data, so in sap what about for all entries of Limit?
and will lose data to use for all entries of statements?
have function in sap to get data like 'MARC_ARRAY_READ' about MEBW.
THANK YOU!

thank you!
what about for all entries of Limit?
and will lose data to use for all entries of statements?
exist function about get MEBW ARRAY??

HOW TO PRINT THE MATTER IN FOR ALL ENTRIES

HI HOW T PRINT THE FOR ALL ENTRIES MATTER

Hi Naresh,
You can only use FOR ALL ENTRIES IN ...WHERE ...in a SELECT statement.
SELECT ... FOR ALL ENTRIES IN itab WHERE cond returns the union of the solution sets of all SELECT statements that would result if you wrote a separate statement for each line of the internal table replacing the symbol itab-f with the corresponding value of component f in the WHERE condition.Duplicates are discarded from the result set. If the internal table itab does not contain any entries, the system treats the statement as though there were no WHERE cond condition, and selects all records (in the current client).
For example:
SELECT * FROM sflight INTO wa_sflight
FOR ALL ENTRIES IN ftab
WHERE CARRID = ftab-carrid AND
CONNID = ftab-connid AND
fldate = '20010228'.
This condition, return all entries of the sflight.
When using FOR ALL ENTRIES the number of matching records is restricted to the number of records in the internal table. If the number of records in the database tables is too large then join would cause overheads in performance. Additionally a JOIN bypasses the table buffering.

Alternative for / Problems with: "For all entries in data_package"

Hi Guys
I doing some ABAP in a Start Rotine in BW and would like to do the following:
select * from /BI0/PMATERIAL into table 0mat
for all entries in DATA_PACKAGE
where material = DATA_PACKAGE-/bic/zmaterial.
But I get the following error:
E:When using the addition "FOR ALL ENTRIES IN itab", the fields "MATERIAL" and "DATA_PACKAGE-/BIC/ZMATERIAL" must have the same type and length. and length.
ZMATERIAL:
- Length: 28
- Type: CHAR - Character String
ZMATERIAL:
- Length: 18
- Type: CHAR - Character String
According to the error message "For all entries" cannot be used in this case since the lengths are not identical, but is there an alternative way to do what I would like to do?
Thanks in advance, kind regards,
Torben

Hi
one thing you can try like this define one variable in other itab of same type
then loop at the first table and assign it to new field and modify the itab
then use this field with for all entries

I have a problem in using for all entries

Hi i have a problem in using for all entries
i have declared the two internal tables as below
DATA: BEGIN OF ITAB OCCURS 10,
 EBELN LIKE EKKO-EBELN,
 LIFNR LIKE EKKO-LIFNR,
 EBELP LIKE EKBE-EBELP,
 BELNR LIKE EKBE-BELNR,

 END OF ITAB.
DATA: BEGIN OF ITAB1 OCCURS 10,

 MWSKZ LIKE EKPO-MWSKZ,
 LIFNR LIKE EKKO-LIFNR,
 EBELP LIKE EKBE-EBELP,
 BELNR LIKE EKBE-BELNR,
 END OF ITAB1.
and now i have tried to move the values in those internal tables using these statements
 SELECT A~EBELN A~LIFNR A~KNUMV B~VGABE B~EBELP B~GJAHR B~BELNR
 FROM EKKO AS A
 INNER JOIN EKBE AS B ON B~EBELN = A~EBELN

 INTO CORRESPONDING FIELDS OF TABLE ITAB1
 FOR ALL ENTRIES IN ITAB
 WHERE EBELN = ITAB-EBELN.
 LOOP AT ITAB1.
 READ TABLE ITAB WITH KEY EBELN = ITAB-EBELN.
 ITAB-EBELN = ITAB1-EBELN.
 ITAB1-LIFNR = ITAB-LIFNR.
 ITAB1-EBELP = ITAB-EBELP.
 ITAB1-BELNR = ITAB-BELNR.
 ITAB1-EBELP = ITAB-EBELP.
 APPEND ITAB1.
 ENDLOOP.
But when i was using loop then it was displaying values in debugging mode but while i was trying to execute it was taking a lot of time i thought that it was due to more information in the already declared internal table so i have tried to remove the previous entries but it was showing an error while i was removing the old entries
and when i remove the loop at itab1 then i'll get output directly but it was displaying the itab fields which is my 1st internal table but not the values of itab1 can u explain me what is the possible error for that
Regards ,
Pavan

before using for all entries in, u need to check whether the driver internal table is empty, if it is empty, u should not enter into select statement.
if u wont use this check means, when the driver internal table is empty, the second select will take all the entires from the tables.
SELECT AEBELN ALIFNR AKNUMV BVGABE BEBELP BGJAHR B~BELNR
 FROM EKKO AS A
 INNER JOIN EKBE AS B ON BEBELN = AEBELN
 INTO CORRESPONDING
 FIELDS OF TABLE ITAB WHERE B~VGABE = '2'.
if itab[] is not initial.
 SELECT EKPOEBELN EKPOMATNR EKPOTXZ01 EKPOWERKS EKPO~NETWR
 EKPOMENGE EKPOMWSKZ
 FROM EKPO
 INTO CORRESPONDING FIELDS OF TABLE ITAB1
 FOR ALL ENTRIES IN ITAB
 WHERE EBELN = ITAB-EBELN.
endif.
I hope this will help u.

Select... for all entries in...

Hi,
Can anybody help me to sort out this issue. This select should work. I m filling an itab with distinct pernr. in temp it should give all the records for which pernr should not be in itab.
report ZTEST4.
data : begin of ITAB occurs 0,
 PERNR like PA0001-PERNR,
 ename like pa0001-ename,
 end of ITAB.
data : temp like itab occurs 0 with header line.
clear : ITAB, TEMP.
refresh : ITAB,TEMP.
select distinct PERNR into table ITAB from PA0001 where PERNR le 10.
select PERNR ENAME into table TEMP from PA0001
for all entries in ITAB where pernr not in itab-pernr.
sort TEMP by PERNR.
break-point.

Hi Sagar,
If i understand it well, you exclude all PERNR LE 10.
But first things first.
You cannot use the FOR ALL ENTRIES in your case (it doesn't allow the operator "NOT IN").
Your code should be:
REPORT ztest4.
TYPES: BEGIN OF ty_itab,
 pernr TYPE persno,
 ename TYPE emnam,
 END OF ty_itab.
DATA : itab TYPE ty_itab occurs 0,
 wtab TYPE ty_itab.
CLEAR: itab,
 wtab.
SELECT pernr ename
 INTO TABLE itab
 FROM pa0001
 WHERE pernr LE 10
 ORDER BY pernr.
IF sy-subrc EQ 0.
DELETE ADJACENT DUPLICATES FROM itab COMPARING pernr.
ENDIF.

For All Entries with two tables

Hi All,
         Can we use FOR ALL ENTRIES with two tables. for example
SELECT * FROM MKPF INTO TABLE T_MKPF
         WHERE BUDAT IN S_BUDAT.
SELECT * FROM MARA INTO TABLE T_MARA
         WHERE MTART IN S_MTART AND
                        MAKTL IN S_MAKTL.
SELECT * FROM MSEG INTO TABLE T_MSEG
       FOR ALL ENTRIES IN "T_MKPF AND T_MARA"
              WHERE MBLNR EQ T_MKPF-MBLNR AND
                             MATNR EQ T_MARA-MATNR.
can we do it like this or any other way to do this plz tell. I waitting for your responce.
Thanks
Jitendra

Hi,
u cannot do like this....chek some documentation on it..
1. duplicate rows are automatically removed
2. if the itab used in the clause is empty , all the rows in the source table will be selected .
3. performance degradation when using the clause on big tables.
Say for example you have the following abap code:
Select * from mara
For all entries in itab
Where matnr = itab-matnr.
If the actual source of the material list (represented here by itab) is actually another database table, like:
select matnr from mseg
into corresponding fields of table itab
where .
Then you could have used one sql statement that joins both tables.
Select t1.*
From mara t1, mseg t2
Where t1.matnr = t2.matnr
And T2..
So what are the drawbacks of using the "for all entires" instead of a join ?
At run time , in order to fulfill the "for all entries " request, the abap engine will generate several sql statements (for detailed information on this refer to note 48230). Regardless of which method the engine uses (union all, "or" or "in" predicates) If the itab is bigger then a few records, the abap engine will break the itab into parts, and rerun an sql statement several times in a loop. This rerun of the same sql statement , each time with different host values, is a source of resource waste because it may lead to re-reading of data pages.
returing to the above example , lets say that our itab contains 500 records and that the abap engine will be forced to run the following sql statement 50 times with a list of 10 values each time.
Select * from mara
Where matnr in ( ...)
Db2 will be able to perform this sql statement cheaply all 50 times, using one of sap standard indexes that contain the matnr column. But in actuality, if you consider the wider picture (all 50 executions of the statement), you will see that some of the data pages, especially the root and middle-tire index pages have been re-read each execution.
Even though db2 has mechanisms like buffer pools and sequential detection to try to minimize the i/o cost of such cases, those mechanisms can only minimize the actual i/o operations , not the cpu cost of re-reading them once they are in memory. Had you coded the join, db2 would have known that you actually need 500 rows from mara, it would have been able to use other access methods, and potentially consume less getpages i/o and cpu.
In other words , when you use the "for all entries " clause instead of coding a join , you are depriving the database of important information needed to select the best access path for your application. Moreover, you are depriving your DBA of the same vital information. When the DBA monitors & tunes the system, he (or she) is less likely to recognize this kind of resource waste. The DBA will see a simple statement that uses an index , he is less likely to realize that this statement is executed in a loop unnecessarily.
Beore using the "for all entries" clause and to evaluate the use of database views as a means to:
a. simplify sql
b. simplify abap code
c. get around open sql limitations.

Like operator in for all entries

hi all,
may i know how to apply like for "for all entries"
where the first position is 9.
syntax is incorrect. hope can get help.
thanks
CONCATENATE itab-xx+0(1) '%' INTO v_kstar.
SELECT kstar txt20 INTO TABLE it_act
    FROM aaa
    FOR ALL ENTRIES IN itab
    WHERE kstar like v_kstar AND
          spras = sy-langu.

in that case u have to call with in loop itself, may be there is another way also.
do v_times times
     varying v_name
     from dept-dept01
     next dept-dept02.
    concatenate p_rprctr '%' v_name into v_dep.
   concatenate '%' v_name into v_dep.

Select query like For all Entries

Hi,
I have a requirement like:
I need to extract data (BKTXT) from table BKPF based on some criteria, into one internal table and I need to query on REGUP table for the above data, the selection criteria on REGUP as follows:
BKTXT(Document Header Text with 25 Char) is a combination of DATE and character string.
Ex: bkpf-bktxt = 20060710-PL02 (YYYYMMDD)
it is like LAUFD + LAUFI (of table REGUP)
i.e: LAUFD (REGUP) = 07/10/2006 (MM/DD/YYYY) and LAUFI(REGUP) = PL02
here I am thinking to use a select query on REGUP using FOR ALL ENTRIES of table i_bkpf..
How can I change the date format YYYYMMDD to MM/DD/YYYY for my requirement?
(( Run-on Date (REGUP-LAUFD) = the first 8 characters in the Document Header Text (BKPF- BKTXT) in MM/DD/YYYY date format (e.g. 07/10/2006)
 Run ID (REGUP-LAUFI) = the 10th character through the 15th character in the Document Header Text (BKPF- BKTXT)

It is not possible to do in the way you are thinking of doing. "For all entries" requires you to have the itab table field and the database table field to have the same type and length. So something like below will not work.
TABLES: regup.
DATA: BEGIN OF itab OCCURS 0,
 text LIKE bkpf-bktxt.
DATA: END OF itab.
DATA: BEGIN OF itab_regup OCCURS 0.
 INCLUDE STRUCTURE regup.
DATA: END OF itab_regup.
SELECT * INTO TABLE itab_regup
 FROM regup FOR ALL ENTRIES IN itab
 WHERE laufd = itab-text+0(8).
If you run this code, you will get an error as follows:
"When using the addition "FOR ALL ENTRIES IN itab", the fields "LAUFD" and "ITAB-TEXT+0(8)" must have the same type and length."

Issue with FOR ALL ENTRIES

Hi All,
I have used FOR ALL ENTRIES statement in while selecting data based on some other internal table (to avoid select within loop).
While using FOR ALL ENTRIES, the target table (internal table in which data is getting stored) is getting affected.
The other fields are becoming zero and several rows gets delerted from the internal table after performing select query.
How to avoid this bug?
Kindly help me out....

Pavan

hi after the for all entries statement did you used the read statement .
if not you will not get any data ..check this program..
tables:mara,marc.
data:begin of itab occurs 0,
     matnr like mara-matnr,
     end of itab.
data:begin of itab1 occurs 0,
     matnr like marc-matnr,
     werks like marc-werks,
     end of itab1.
select   matnr
      from mara
      into corresponding fields of table itab.
      if   itab is initial.
      select matnr
              werks
             from marc
             into table itab1
             for all entries in itab

Problem with for all entries

Hi all,
When i was trying to use for all entries, i am not able to pull records inside my internal table. Though both of the tables have the common key fields between them(and ofcourse have entries in that). Now what i have analyzed was, the first table is having 7 primary keys and the one i am using for 'for all entries' comes 6th. Does this gives any impact in pulling records inside my internal table?.Else please give me a possible solution for this. The alternate statement(a normal select query with * ) that i had used for this reserved my dialog processor for a while. Which resulted in 'time exceeded' short dump.

Hi,
The WHERE clause of the SELECT statement has a special variant that allows you to derive conditions from the lines and columns of an internal table:
SELECT ... FOR ALL ENTRIES IN <itab> WHERE <cond> ...
<cond> may be formulated as described above. If you specify a field of the internal table <itab> as an operand in a condition, you address all lines of the internal table. The comparison is then performed for each line of the internal table. For each line, the system selects the lines from the database table that satisfy the condition. The result set of the SELECT statement is the union of the individual selections for each line of the internal table. Duplicate lines are automatically eliminated from the result set. If <itab> is empty, the addition FOR ALL ENTRIES is disregarded, and all entries are read.
The internal table <itab> must have a structured line type, and each field that occurs in the condition <cond> must be compatible with the column of the database with which it is compared. Do not use the operators LIKE, BETWEEN, and IN in comparisons using internal table fields. You may not use the ORDER BY clause in the same SELECT statement.
You can use the option FOR ALL ENTRIES to replace nested select loops by operations on internal tables. This can significantly improve the performance for large sets of selected data.
Hope this is useful
