Duplicate Values in an Internal Table

Hi,
Is it possible to delete records having Duplicate Values in a field, in an Internal Table, but in the situation when the Internal Table is NOT sorted on that field ?
Regards,
Pankaj.

Hi Pankaj,
i think you have to create a copy of your itab and collect.
try this:
REPORT ZGRO_TEST.
DATA: BEGIN OF ITAB OCCURS 0,
        MATNR LIKE MARA-MATNR,
        VBELN LIKE VBAK-VBELN,
      END   OF ITAB.
DATA: BEGIN OF ITAB1 OCCURS 0,
        MATNR LIKE MARA-MATNR,
        VBELN LIKE VBAK-VBELN,
      END   OF ITAB1.
START-OF-SELECTION.
itab-matnr = '000000000000000111'. itab-vbeln = '0000000011'. append itab.
itab-matnr = '000000000000000113'. itab-vbeln = '0000000013'. append itab.
itab-matnr = '000000000000000111'. itab-vbeln = '0000000011'. append itab.
itab-matnr = '000000000000000112'. itab-vbeln = '0000000012'. append itab.
itab-matnr = '000000000000000111'. itab-vbeln = '0000000011'. append itab.
itab-matnr = '000000000000000112'. itab-vbeln = '0000000012'. append itab.
itab-matnr = '000000000000000113'. itab-vbeln = '0000000013'. append itab.
loop at itab.
itab1 = itab.
collect itab1.
endloop.
loop at itab.
write: / itab-matnr, itab-vbeln.
endloop.
write: / sy-uline.
loop at itab1.
write: / itab1-matnr, itab1-vbeln.
endloop.
END-OF-SELECTION.
if you whant it back in itab. refrash itab and copy itab1 to itab.
Hope it helps.

How to check a field value within an Internal table

Hi Friends,
My requirement is:
I have a line item of PO records, in that each line item of Plant field should not diffe with other line items. If it differs or say the records have different plant values line items, then I have to throw an error message.
Below example for better understanding.
lineitem Plant
010       ABC
020       ABC
030       XYZ
040       LKG
So, my report will throw an error like "All line items must be identical'.
How to do proceed it.Please advise.
Thanks & Regards
Sankar.

Hi Sankar
first you need to fetch all the values in one internal table from your PO.
After that create an internal table with only plant field and move all the plan values in this table.
let assume ITAB is a table with all the values. and ITAB1 with plant only.
wa_itab is the work area for ITAB and wa_itab1 is WA for ITAB1.
ITAB has all the values and ITAB1 has all the values only for plant.
delete adjacent duplicate from itab1 compairing plant.
loop at itab1 into wa_itab1. " this will fetch all the plant values in workarea.
read table itab into wa_itab where wa_itab-plant = wa_itab1-plant. " this will fetch only the values matching to the table itab1
if su-subrc <> 0.
message 'plants are not similar' TYPE 'E'.
elseif sy-subrc = 0.
write your code*.
endif.
endloop.
hope this will help you.
Thanks

Thanks,
Ujjwal

Hi Ujjwal
The reason behind this is that you are using AT NEW.... ENDAT block in your coding.
When you use AT NEW field statements, the fields in the work area after the field get converted into ********.
Check values in your work area I_RECORD in debugging inside AT NEW statement and you will understand what I am saying.
In your case all the fields from header line of I_RECORDS which come after field CLASS are getting converted into *******,
hence the error.
Try using a temporary work area, say w_record. Pass value of I_record to w_record before AT NEW statement.
And use w_record-fields instead of I_record-fields. And your program should work.

Initializing values in an internal table

hi
how to initialize values in a internal table
according to my requirement i need to initialize (both character and currency) values present in the internal table based on certain conditions
vamsi

hi
As i understood you want to clear only selected fileds not the complet record..
create a Field symobl the loop at the table.. inside the loop check the condtion the just clear the filed.
example: you have itab type mara.
then
FIELD-SYMOBOLS <FS_WA_ITAB> TYPE MARA.
LOOP AT ITAB ASSIGNING <FS_WA_ITAB>.
IF X = XXX (YOUR CONDITION)
CLEAR: <FS_WA_ITAB>-FIELD2,
<FS_WA_ITAB>-FIELD3. (If u want to clear only filed2 and field3)
clear <FS_WA_ITAB>. (if you want to cleatr the complete record)
ENDIF.
ENDLOOP.
Why iam suggestin the filed-symobol is.. it is direcltly work on internal table body so u no need to update the table agian
Please Close this thread.. when u r problem is solved

Transferring checkbox values on ALV to value in the internal table?

Hi,
I'm using an ALV grid (CL_GUI_ALV_GRID) to display an internal table. I want users to be able to select one or many rows and those checked lines to be marked as X in my internal table. I have a field, check(1), in my internal table displayed on the ALV, but when I tick one line on the ALV and debug, I don't see an X in the check field on that line in my internal table.
I've successfully written code to select and deselect all lines and those values copy back to my internal table so why don't the single lines?
CASE sy-ucomm.
    WHEN 'SELECT_ALL'.
*   select all lines
      LOOP AT tbl_data INTO wa_data.
        MOVE 'X' TO wa_data-check.
        MODIFY tbl_data FROM wa_data.
      ENDLOOP.
    WHEN 'DESELECT'.
*   deselect all lines
      LOOP AT tbl_data INTO wa_data.
        CLEAR wa_data-check.
        MODIFY tbl_data FROM wa_data.
      ENDLOOP.
ENDCASE.
Do I have to add some code in the PAI to transfer the values?
Any suggestions welcome,
Gill

Yes, I have.
The checkbox is appearing on the screen and is populated/cleared when I click the select/deselect buttons (this transfers the values in my internal table to the screen). But when I just tick one line and then debug that line isn't showing as having X in the check field in my internal table.
Somehow I need to transfer the tick values on screen to my internal table.

If my internal table contain this kind of data with repeted document numbers than i want the document number which contains only the vendor number.
Pls help me with the appropriate logic,its urgent.
Thanks a lot

Hi,
<u><b>Deleting Adjacent Duplicate Entries</b></u>
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM <itab>
[COMPARING <f1> <f2> ...
|ALL FIELDS].
The system deletes all adjacent duplicate entries from the internal table <itab>. Entries are
duplicate if they fulfill one of the following compare criteria:
Without the COMPARING addition, the contents of the key fields of the table must be
identical in both lines.
If you use the addition COMPARING <f1> <f2> ... the contents of the specified fields <f1>
<f2> ... must be identical in both lines. You can also specify a field <fi> dynamically as
the contents of a field <ni> in the form (<ni>). If <ni> is empty when the statement is
executed, it is ignored. You can restrict the search to partial fields by
specifying offset and length.
If you use the addition COMPARING ALL FIELDS the contents of all fields of both lines
must be identical.
You can use this statement to delete all duplicate entries from an internal table if the table is
sorted by the specified compare criterion.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4.
Examples
DATA: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB LIKE HASHED TABLE OF LINE WITH UNIQUE KEY COL1.
DO 4 TIMES.
LINE-COL1 = SY-INDEX.
LINE-COL2 = SY-INDEX ** 2.
INSERT LINE INTO TABLE ITAB.
ENDDO.
LINE-COL1 = 1.
DELETE TABLE ITAB: FROM LINE,
WITH TABLE KEY COL1 = 3.
LOOP AT ITAB INTO LINE.
WRITE: / LINE-COL1, LINE-COL2.
ENDLOOP.
The output is:
2 4
4 16
The program fills a hashed table with a list of square numbers. The DELETE
statement delete the lines from the table where the key field COL1 has the contents 1 or 3.

Distinct values in an internal table

How can I extract the distinct values of a particular field in an
internal table?

Hello Gregory
Another possibility is to sort you itab by the particular field(s) and then delete any duplicates:
SORT itab BY field1.
DELETE ADJACENT DUPLICATES FROM itab
COMPARING field1.

Display data to edit based on fields and its value defined in internal tabl

I need to display data in a internal table for editing in a screen.
you have a internal table with field name , data types and its value. I need to display data in a screen ( sceen painter not in a report) row by row in vrtical format.
The internal table's structure not fix. you can have any number of fields in the internal table.
Can you please send me code if it is available with you or send me any senario in SAP if any ...so that i can debug to extract the code..
have to display data vertically as below in editable format,
for example,
Airline
Flight Number
Flight date
Flight price
Airline Currency
Plane Type
Maximum capacity
Occupied econ.
Total
No of fields will change.
also F4 help needs to be attached with each field.
I think it can be done through step loop. can anybody give sample code or tell me where to find in SAP or somewhere else?
it will be great help to me..

BRFplus: Problem updating values in an internal table in a loop expression

Hi
I'm looking into the loop expression type of BRFplus and I have come across a problem updating an internal table, I'm trying to create and populate the table using a loop, here is the functionality I'm trying to achieve:
In a rule set create an internal MONTH_TBL table containing 12 rows of two columns: MONTH_NUM containing values 1 through 12 and MONTH_VAL containing an amount (initially 0,00 EUR in all 12 rows).
After initializing the table traverse through SFLIGHT table and for each row add PRICE from the table to MONTH_VAL in the row of MONTH_TBL corresponding to the month of FLDATE field in SFLIGHT.
The initialization of MONTH_TBL works as intended, as does the traversal of and retrieval of values from SFLIGHT. The problem however is the update of the internal table MONTH_TBL (defined as result data object for the function). I don't get an error, but the tables does not get updated, and I cannot seem to find out what the problem is. I would have attached an XML extract of the function + ruleset for information, but it dosen't seem like that is possible, I could e-mail it on request (for SAP employees with access to system QU5 the function is LOOP_TEST in application Z_KLAUS_TEST).
I hope that this is sufficient information to understand the issue that I'm dealing with.
best regards
Klaus Stenbæk, KMD

Hi Klaus,
The Loop expression is part of NW 7.02 which is not yet released. When you experience the problem as part of a test you should have a contact at SAP for dealing with problems/errors. Usually SAP-internal messages are used for this purpose. Please clarify with your SAP contact how the model is.

Loop not working for check of duplicate values in a repeating table

I have a form that is used for marking down problem items, describing the problems and assigning a value to the specified item. In some cases the problems belong to the same class. When they do, the value associated with the problem should only be marked once. If another problem in the same class is documented the value should not be recorded the second time. I have a variable that is called based on a switch statement in the exit event of the field that records the problem item number. The script in the variable is then supposed to check for duplicate values in the table. If no other problem item in that class is selected, then the problem value should be assigned a number. If another item from the same class has already been entered, then the problem value should just be left blank. I will paste the script for the variable below as well as the switch statement. When I used to call the variable based upon the change event for the problem item, the script work. At that time, the switch statement was related to a drop-down menu. We decided to get rid of the drop-down and just have the used type the item number. But to do so, I had to move the switch statement to the exit event for the field. when I did this, the script in the variable no longer worked properly. Here is the switch statment followed by the script in the variable:
this.rawValue = this.rawValue.toLowerCase();
var bEnableTextField = true;

var nNodesLength = oFields.length; //assigns the number of rows to a variable
var currentRow = xfa.resolveNode("form1.MAINBODYSUB.ViolationsTableSubform.ViolationsTable.ViolCorrSection ").index;
var currentDebit = xfa.resolveNode("form1.MAINBODYSUB.ViolationsTableSubform.ViolationsTable.ViolCorrSection [" + currentRow + "].ViolationsText.DebitVal");
for (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++) // this loops through Item Numbers looking for duplicate violations
//console.println("nNodeCount: " + nNodeCount);
var nFld = xfa.resolveNode("form1.MAINBODYSUB.ViolationsTableSubform.ViolationsTable.ViolCorrSection [" + nNodeCount + "]");
//console.println("nFld.ViolationsText.ItemNo: " + nFld.ViolationsText.ItemNo.rawValue);
     if (nFld.ViolationsText.ItemNo.rawValue == "1a" || nFld.ViolationsText.ItemNo.rawValue == "1b" || nFld.ViolationsText.ItemNo.rawValue == "1c" || nFld.ViolationsText.ItemNo.rawValue == "1d") // looks for other 1s
          currentDebit.rawValue = "";
          nNodeCount = nNodesLength; // stop loop
     else
        currentDebit.rawValue = "5";
So, if you enter 1b the first time, you should get a value of 5 appearing in the debit value field. If you enter 1c next, because it belongs to the same group of class of problem items, there should be no value assigned. What happens now is that the values for 1b and 1c don't appear at all because the form thinks that the first 1b entry already existed.
Any ideas? I have a stripped down version of the form that I can email to someone for reference if that would help. Thanks
P.S. I am working with LiveCycle Designer ES 8.2.1....

Hi,
I can have a look at your form, but can you host it somewhere like Acrobat.com or google docs and add a link to it here.

How to Fill values in BAPI internal table ?

I am creating sales order from ABAP Dynpro , all the values are getting passed to bapi except those in internal table, it gives lead selection error and whn i change the cardinality of the Node to 1.1 to shows the page but whenever i create the SO it gives WRONG_DATA error . I debugged it and found the data in the internal table for material is not getting passed.

Hi Jasjit,
Could you be a bit more clear about the issue you are facing.
Try using the cardinality 0:n for node that holds the data that you are passing as internal table to bapi.

SET_TABLE_FOR_DISPLAY - Edited value from dynamic internal table need to be captured

Hi all,
I have created 2 tabstrip screns which contain ALV GRID DISPLAY in a container with dynamic internal table and editable columns .I want to capture the edited value from this ALV GRID display.I have used SET_TABLE_FOR_DISPLAY and for this dynamc internal table is passed which is Field symbol and editable columns have to be captured for further updation into another ztable.
When i used check_changed_data i am getting dump as field symbol not assigned.
Below is the code : How can i get edited column value from below code
call method alv_list->set_table_for_first_display
    exporting
            is_layout                     = gs_layout
    changing
      it_outtab                     = <fs_dynamic_table>
      it_fieldcatalog               = it_fieldcat[]
    exceptions
      invalid_parameter_combination = 1
      program_error                 = 2
      too_many_lines                = 3
      others                        = 4.
if sy-subrc <> 0.
* Implement suitable error handling here
endif.
Kindly help me to solve this.
With Thanks,
Dina.

please provide more info about the dump to try to help you
as max said, it could be because the field symbol is not global and if its global maybe you are not refering well to the column
i assume that you are using "ASSIGN COMPONENT comp OF STRUCTURE struc TO <fs>" to capture the value changed
validate always the sy-subrc after the assignment.
but the check changed data have parameters that have the old and new values
please provide more info...
Regards
