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 : '
 I_DATA-PRGNAME
 INTO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 MOVE '*****************************************' TO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 CONCATENATE TEXT-024 " Material
 TEXT-025 " MRP
 INTO t_objtxt-line
 SEPARATED BY C_COMMA.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 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
 I_DATA-BERID
 INTO t_objtxt-line
 SEPARATED BY C_COMMA.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 AT END OF MATNR.
 MOVE '' TO t_objtxt-line.
 APPEND t_objtxt.
 CLEAR t_objtxt.
 MOVE '*****************************************' TO t_objtxt-line.
 CONCATENATE t_objtxt-line '******************' INTO t_objtxt-line.
 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.
Thanks,
Deep.

Can you paste the total code.

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.

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.
ambichan.
ambichan.

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.

Internal table logic issue

Hi All,
I have one logical issue related to internal table manipulation.
I have one internal table :
I_DAT - This is related to Loading/Unloading of Goods.
for example with 3 fields
VSTEL, KUNNA, KMMANG.
Now suppose my data looks like this after sorting:
VSTEL KUNNA KMMANG
100 - -
200 - -
300 - -
400 - -
- 500 X
- 600 X
- 700 X
- 800 X
Here 100,200,300,400 are Loading points.
ANd 500,600,700,800 are unloading points.
Now what i want is For loading & Unloading points i need to pick up Address and print one after other.
But how they need to print is:
FOR INITIAL LOADING OF
ADDRESS- For 100
FIRST STOP: FOR LOADING OF
ADDRESS- For 200
SECOND STOP: FOR LOADING OF
ADDRESS- For 300
Etc .....
Then
FOR UNLOADING OF:
ADDRESS- For 400
FIRST STOP: FOR UNLOADING OF
etc.
FINAL STOP: FOR FINAL UNLOADING OF
We might get as many records :
Can any body give me the logic:
Printing Address is not a problem:
But Above every address we need to print FIRST STOP, SECOND etc like that.
For this i need logic.
Can anybody give the solution!
Thanks in advance.
Thanks & Regards,
Prasad.

Try this.I think you want output like this......
DATA: BEGIN OF LINE,
 CARRID TYPE SBOOK-CARRID,
 CONNID TYPE SBOOK-CONNID,
 FLDATE TYPE SBOOK-FLDATE,
 CUSTTYPE TYPE SBOOK-CUSTTYPE,
 CLASS TYPE SBOOK-CLASS,
 BOOKID TYPE SBOOK-BOOKID,
 END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY TABLE LINE.
SELECT CARRID CONNID FLDATE CUSTTYPE CLASS BOOKID
 FROM SBOOK INTO CORRESPONDING FIELDS OF TABLE ITAB.
LOOP AT ITAB INTO LINE.
AT FIRST.
 WRITE / 'List of Bookings'.
 ULINE.
ENDAT.
 AT NEW CARRID.
 WRITE: / 'Carrid:', LINE-CARRID.
 ENDAT.
 AT NEW CONNID.
 WRITE: / 'Connid:', LINE-CONNID.
 ENDAT.
 AT NEW FLDATE.
 WRITE: / 'Fldate:', LINE-FLDATE.
 ENDAT.
 AT NEW CUSTTYPE.
 WRITE: / 'Custtype:', LINE-CUSTTYPE.
 ENDAT.
 WRITE: / LINE-BOOKID, LINE-CLASS.
 AT END OF CLASS.
 ULINE.
 ENDAT.
ENDLOOP.
This is also helpful......
LOOP AT <itab>.
AT FIRST. ... ENDAT.
 AT NEW <f1>. ...... ENDAT.
 AT NEW <f2 >. ...... ENDAT.
 <single line processing>
 AT END OF <f2>. ... ENDAT.
 AT END OF <f1>. ... ENDAT.

Reg. internal table logic

Hi,
I have an internal table with 5 fields (Vbeln, A, B, C, D ) and records like this:
Record1:
Field vbeln (value is 6000000001), Field A (value is 2006), Field B (value is 1130), Field C (value is initial), Field D (value is initial)
Record1:
Field vbeln (value is 6000000001), Field A (value is initial), Field B (value is initial), Field C (value is 2005), Field D (value is 1134)
Now whenever, Field A and Field B has values, field C and field D are initial and vice versa.
I Want to get all of the field values in just one record like below when the key vbeln is same.:
Field vbeln (value is 6000000001), Field A (value is 2006), Field B (value is 1130), Field C (value is 2005), Field D (value is 1134)
I know I can create another internal table, copy the contents, use the looping logic and achieve the same but wondering if there is any better way of doing the same?
Appreciate your input.
Thanks!

Hi,
You need another internal tables. Please try this.
SORT ITAB1.
ITAB2[] = ITAB1[].
LOOP AT ITAB1.
LOOP AT ITAB2 WHERE ITAB2-VBELN EQ ITAB1-VBELN
                  AND ITAB2-DATE1 NE ITAB1-DATE1
                  AND ITAB2-TIME1 NE ITAB1-TIME1.
    ITAB3-VBELN = ITAB1-VBELN.
    ITAB3-DATE1 = ITAB1-DATE1.
    ITAB3-TIME1 = ITAB1-TIME1.
    ITAB3-DATE2 = ITAB2-DATE2.
    ITAB3-TIME2 = ITAB2-TIME2.
    APPEND ITAB3.
ENDLOOP.
ENDLOOP.

Internal table logic required

Hi ,
I have two internal tables having with different structures . Finally I need to pass data to final internal table.
In runtime we have data in only one table. The final internal table should take either internal1, or internal table 2.
it_final_data[] = it_first_data[].
or
it_final_data[] = it_sec_data[].
i have to one generic include , it will understands the IT_final_data internal table only.
please help me.
regards,
Ajay

Hi Ajay,
     Build your final internal table with all the fields from first and second internal table. Use the below logic to move the data to the final internal table depending on the internal table data which you want to display.
IF not it_first_data[] is initial.
loop at it_first_data.
    move-corresponding it_frist_data to it_final_data.
    append it_final_data.
endloop.
else.
   loop at it_second_data.
    move-corresponding it_second_data to it_final_data.
    append it_final_data.
endloop.
endif.
Hope this works for you.

Jayaram

Internal Table Logic Needed

Hi all,
I have a requirement regarding data processing in a internal table,
internal table consists of filelds Vendor,Material and Scheduling Dates and Total Qty.
Here i need to fill the field Total Quantity, individual addition of quanties of that material for a particular vendor .
Let us consider intitially my internal table consists of data like this with these fields.
 Vendor , Material , qty(individual), Total qty , Schedule dates
 v1 , m1 , 10
 v1 , m1 , 10
 v1 , m1 , 20
 v1 , m2 , 5
 v1 , m2 , 10
 v2 , m2 , 20
 v2 , m2 , 15
 v2 , m3 , 20
 v2 , m3 , 10
 Initiall the total qty field is empty i need to fill tht field for the last item for a particular material Like M1
for vendor v1 and total qty of m2 for vendor v1, total qty of m1 for v2, total qty of m2 for v2 and so on.
Requied output should be like this.
 Vendor , Material , qty(individual) Total qty Schedule dates
 v1 , m1 , 10 , 0
 v1 , m1 , 10 , 0
 v1 , m1 , 20 , 40(101020)
 v1 , m2 , 5 , 0
 v1 , m2 , 10 , 15(5+10)
 v2 , m2 , 20 , 0
 v2 , m2 , 15 , 35(20+15)
 v2 , m3 , 20 , 0
 v2 , m3 , 10 , 30(20+10)
Here i made one thing , i calculated the total qty of material for particular vendor.
Like
 Vendor Material Total Qty
 v1 , m1 , 40
 v1 , m2 , 15
 v2 , m2 , 35
 v2 , m3 , 30
Finally i need the logic by using Control Events(At New , At End of ) to adjust that total qty of a material for a particular vendor by Modifying the internal table.
i hope my problem is clear , pls let me know if any clarifications needed. and
code for the same .
Thannks in advance,
Niranjan.

Hi,
Solution is here.
sort itab by vendor material.
field-symbols: <itab> like line of itab.
loop at itab assigning <itab>.
on change of vendor.
clear flag.
endon.
add <itab>-quanity to lw_quantiy.
*--here pdate internal table end of each similar kind of record
at end of.
flag = 'x'.
<itab>-totalqty = lw_quantiy.
clear lw_quantiy
endat.
*--rest of record update zero by checking flag
if flag is initial.
<itab>-totalqty = 0.
endif.
endloop.
close this thread if you got solution.

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.

Question on internal table logic..

Gurus,
I have a internal table as follows:
it_tab:
ID---ACTION---CHANGE
A1-----X--
B2----
U
C1-----X--
U
C2-----X--
Without looping at the table, how can I find get the result that the internal table has 3 ids with ACTION ='X'
and 1 ID with ACTION = X and Change = U.
Regards,
Rajesh.

I agree with Rob, why not loop?
First thing without loop that comes to mind is
Using the Read statement 4 times with index 1,2,3 & 4.

Hi Praveen,
You have to SORT the internal table ITAB by a field of your requirement. Then DELETE adjacent entries in the internal table by comparing the field of interest.
SORT ITAB BY NUM1 NUM2.
DELETE ADJACENT DUPLICATES FROM ITAB COMPARING NUM1 NUM2.
After doing this you can perform the required actions on ITAB.
Hope this has cleared your doubt.

Internal table Logic need

Hi ,
I have one Internal table it_marc contains the MATNR
and one more final internal table it_final. I want to read the all MATNR from IT_FINAL by using IT_MARC which contains the same MATNR. I mean all the MATNRs even dupliacates also.

Hi,
Use For all entries.
Select matnr from it_marc

Internal Table - logic for Chunk

Hi,
I have an internal table with n records.
I want to use at a time say max of 20 records .
This is calling a BDC.
i.e.

take 20 records.
call BDC.
then next set of recrds.
repeat process till all records processed.
Thanks in Advance.

Hi,
try this way.
data: count type i.
loop at table
if count LE 20.
    add 1 to count.
else.
    clear count.
    call bdc.
    "refresh all the concerned tables and variables for the next 20 records.

Or.
loop ...
WHILE count le 20.
   ADD 1 TO count.
ENDWHILE.

This is Regarding internal tables

Hi to all,
I have 3 internal tables like this.
it_itab1       It_itab2        it_final
!--f1            !-f3           !---f1
!--f2            !-f4           !---f2
                                       !---f3
                                       !---f4
the fields are like this.now i want to move the data from first two internal tables to final internal table.

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..
