Creation of view and use it as internal table

dear community,
My questions is taht i am write a select quary in that data is very huge so that it cant inserted in to internal table(memory size of internal table) so i thing that i create aview same as data base table and when write the select quary use packsize and transfer recoerd ds in that view and use this view in my program
is above logic can work or not
also is size of view is greater than internal table memory size.

Writing the large volume to another table(which a view is just a view of a table or group of tables) is not going to solve the problem. You still have to select the data from the view(or table). Like I said in your other threads, you need to read by package size, and do something with that subset, whether it is summaring, or writeing to another system via RFC.

Dynamic creation of variables and alv grid output/internal table

Dear Experts
I am stuck in an inventory ageing report which is to be done year wise. the scenario is as follow.
selection screen i enter the year 2011 or 2010 or 2009.
the output should show me 2011-2007 or 2010-2007 or 2009-2007. the alv grid should always start from 2007 and end at the year that is entered in the selection screen.
Now how can i create a dynamic variables to store the values of the corresponding yr and also how can i create a dynamic internal table to store these values.
Thanks & Regards

Hi Zamir,
if you are new to ABAP you may leave old and buggy techniques behind.
If you want to create the table dynamically, please do not use l_alv_table_create=>create_dynamic_table because it is limited and always triggers a possibly unwanted database commit.
You better use RTTS dynamic runtime type services, i.e. check the example for [Creating Flat and Complex Internal Tables Dynamically using RTTI|http://wiki.sdn.sap.com/wiki/display/Snippets/CreatingFlatandComplexInternalTablesDynamicallyusingRTTI].
As done here, leave all outdated ALV technologies behind and start with CL_SALV_TABLE. It is following the object-oriented approach and does not need a field catalog.
You will get used to field-symbols that can be compared to the data referenced by a pointer. For dynamic fields, you may build the field names dynamically, i.e.
DATA:
      lo_structdescr         TYPE REF TO cl_abap_structdescr,
      lo_typedescr           TYPE REF TO cl_abap_typedescr,
      lo_tabledescr          TYPE REF TO cl_abap_tabledescr,
      lr_data                TYPE REF TO data,
      lt_comp_all            TYPE cl_abap_structdescr=>component_table,
      lv_index               TYPE numc2.
    FIELD-SYMBOLS:
      <any>                  TYPE ANY,
      <component>            TYPE LINE OF abap_component_tab,
       <table>                TYPE table.
    DO nnn TIMES.
      lv_index = sy-index.
      lo_typedescr   = cl_abap_typedescr=>describe_by_name( <name of data element> ).
      APPEND INITIAL LINE TO lt_comp_all ASSIGNING <component>.
      <component>-type ?= lo_typedescr.
      CONCATENATE 'YEARVAL' lc_underscore lv_index INTO <component>-name.
      <component>-as_include = abap_true.
      CONCATENATE lc_underscore lv_index INTO <component>-suffix.
    ENDDO.
* create description object for structured type
    lo_structdescr = cl_abap_structdescr=>create( lt_comp_all ).
* create table description object for this
    lo_tabledescr = cl_abap_tabledescr=>create(
                    p_line_type = lo_structdescr
                    p_table_kind = cl_abap_tabledescr=>tablekind_std
                    p_unique     = abap_false ).
* create data object
    CREATE DATA lr_data TYPE HANDLE lo_tabledescr.

I see now that you can do that. Too bad you can't do the same with messages...one at a time.
I'd rather have a "delete all" in messages and VVM if I had a choice. Those tend to pile up and before you know it, you have a hundred to delete!

I have recently transferred data from my old Mac to my new one. The result was good, but I have 2 users now, whose data I want to merge into 1 single user, so to avoid having to switch from one user to the other to view and use certain files. How to do it

I have recently transferred data from my old Mac to my new one. The result was good, but I have 2 users now, whose data I want to merge into 1 single user, so to avoid having to switch from one user to the other to view and use certain files. How to do it?

Here's an easy way:
Pick the user that you want to eliminate (making sure that the remaining user has administrator privileges) and move all of the data that you want to keep into the Shared folder. Reboot or log out and login to the user you want to keep. Copy all the data from the Shared folder into your account - placing it neatly in folders (Documents, Music, Movies, etc.).
Once the data is moved, log into the account you want to delete just once more to make certain that you've grabbed all the data you want to keep. Log out and log back into your admin account and go to System Preferences>Users & Groups and delete the 'old' user.
That should do it.

Unable to view and use iphotos within imovie or idvd

I recently upgraded to iLife '06 and I would like to view and use my iphotos from within imovie. But for some reason I cannot. When I click on the media button, I can bring in any of my iTunes music. But when I click on the photos button, nothing, except for a message to launch iphoto2 or later appears. the Show Photo Settings button is present, but nothing happens when I click. I do keep my photo library on a second hard drive, not the one which stores the applications. I've rebuilt the database several times. any suggestions are appreciated. -ab

I discovered the root of the problem was an " & " used in the file name of my iPhoto library. That is evidently a no-no. After I renemed the library and restarted, all was working fine. -ab

USING SUM IN INTERNAL TABLE

plz give me a simple example for using SUM in internal table and do some calculations in the same internal table.

HI
CHECK WITH THIS
Syntax
SUM.
Effect
The statement SUM can only be specified within a loop starting with LOOP, and is only considered within a AT- ENDAT control structure. Prerequisites for using the statement SUM include using the addition INTO in the LOOP statement, and that the specified work area wa is compatible with the row type of the internal table. In addition, SUM cannot be used when the row type of the internal table itab contains components that are tables.
The statement SUM calculates the component total with the numeric data type (i, p, f) of all rows in the current control level and assigns these to the components of the work area wa. In the control levels FIRST, LAST, and outside of an AT-ENDAT control structure, the system calculates the sum of numeric components of all rows in the internal table.
Example
Control level processing for creating a list. At the end of line groups, the total of reserved places is calculated and issued.
DATA: sflight_tab TYPE SORTED TABLE OF sflight
                  WITH UNIQUE KEY carrid connid fldate,
      sflight_wa LIKE LINE OF sflight_tab.
SELECT *
       FROM sflight
       INTO TABLE sflight_tab.
LOOP AT sflight_tab INTO sflight_wa.
AT NEW connid.
    WRITE: / sflight_wa-carrid,
             sflight_wa-connid.
    ULINE.
ENDAT.
WRITE: / sflight_wa-fldate,

    WRITE: / 'Sum',
              sflight_wa-seatsocc UNDER sflight_wa-seatsocc.
    SKIP.

The type of the database table and work area (or internal table)...

Hello
I am trying to use a database and select all records from it and store them into an internal table.
My code:
Select * from xixi_dbcurrency into table gt_currency.
The error:
"The type of the database table and work area (or internal table) "GT_CURRENCY" are not Unicode-convertible . . . . . . . . . .     "
Any suggestions?
Thank you

Hi Thomas,
Thank you for your inputs above.
But as you suggested is we use INTO CORRESPONDING FIELDS OF TABLE then it resolve the error.
But I have below piece of code:
DATA:    it_new_source TYPE STANDARD TABLE OF _ty_s_sc_1,
              wa_source TYPE _ty_s_sc_1,
              wa_new_source TYPE _ty_s_sc_1,
              ls_target_key TYPE t_target_key.
SELECT * INTO CORRESPONDING FIELDS OF TABLE it_new_source
       FROM /bic/afao06pa100
       FOR ALL ENTRIES IN SOURCE_PACKAGE
       where /bic/fcckjobno = SOURCE_PACKAGE-/bic/fcckjobno
       and /bic/fcckjitid = SOURCE_PACKAGE-/bic/fcckjitid.
But since this is reading into corresponding fields of table the data load from one DSO to other DOS is running for long more that 15 hours and still not getting completed and giving dump.
So if I switch the search to below:
SELECT * FROM /bic/afao06pa100
   INTO TABLE it_new_source
       FOR ALL ENTRIES IN SOURCE_PACKAGE
       where /bic/fcckjobno = SOURCE_PACKAGE-/bic/fcckjobno
       and /bic/fcckjitid = SOURCE_PACKAGE-/bic/fcckjitid.
Then I am getting below error:E:The type of the database table and work area (or internal table) "IT_NEW_SOURCE" are not Unicode convertible.
Can you please advice on this, as performance need to improve in start routine code.
Thank You.

Why using workarea for internal table is better in performance

Please tell me
why using workarea for internal table is better in performance

Hi Vineet ,
Why would we choose to use an internal table without a header line when it is easier to code one with a header line?
it has following reason.
1)Separate Internal Table Work Area:
The work area (staging area) defined for the internal table is not limited to use with just one internal table.
take ex-
Suppose you want two internal tables for EMPLOYEE one to contain all records and one to contain only those records where country = USA. You could create both of these internal tables without header lines and use only one work area to load data into both of them. You would append all records from the work area into the first internal table. You would conditionally append the USA records from the same work area into the second internal table.
2) Performance Issues: Using an internal table without a header line is more efficient than one with a header line
3) Nested Internal Tables: If you want to include an internal table within a structure or another internal table, you must use one without a header line.
If this one is helpful ,then rewards me

Difference between Field symbols and work area for Internal tables

Hi,
In ECC versions we all know that we need to declare the internal tables without headerline, and for handling the internal tables we need to use exclusive work areas.
Currently i have an issue that we have been asked to use field symbols instead of work areas...can any one help me how to use the field symbols and also let me know how it will improve the performance of the program..
Thanks and Regards,
Kathir

Hi
DATA: WA TYPE ITAB.
LOOP AT ITAB INTO WA.
IF WA-FIELD = .....
ENDIF.
ENDLOOP.[(code]
FIELD-SYMBOLS <WA> TYPE ANY.
LOOP AT ITAB ASSIGNING <WA>.
ENDLOOP.
Now the problem is you can't know the name of the fields of the table at runtime, so you can't write:
IF <WA>-FIELD = .....
ENDIF.
Anyway you can create a field-symbols strcturated like the table:
[code]FIELD-SYMBOLS <WA> TYPE ITAB.
LOOP AT ITAB ASSIGNING <WA>.
IF <WA>-FIELD = .....
ENDIF.
ENDLOOP.
I don't know which are the differences for the performance between to use a field-symbol and to use a structure as work-area.
The differnce between the field-symbols and work-area is the field-symbol is assigned directly to the record, so u don't need to do a MODIFY statament to change something:
LOOP AT ITAB INTO WA.
WA-FIELD =
MODIFY ITAB FROM WA.
ENDLOOP.
LOOP AT ITAB ASSIGNING <WA>.
<WA>-FIELD =
ENDLOOP.
These two pieces of abap code do the same action, so probably the field-symbol improve the performance because it do an access directly to the record without to use an external structure as workarea.

How can I view and use PureEdge for my military documents?

I'm new to using Mac computers and I have tons of military forms that I need to use on a daily basis. So I'm asking anyone that has been in the military and used PureEdge to help me out.

I am the one who actually ported PureEdge and Lotus Forms for Mac. As for resizing the window you need to use the screen size controls that are native to the program. You can access the control from the bottom right of the window. Click-Drag (It's actually very easy, and allows the program to look like it belongs in a Mac environment) You can also remove decorations through the program, but it will look like a win98 gui.
Unfortunately several sites have repackaged this program, omitting the original readme. Regardless, Lotus Forms V4.0 and higher is more stable in OSX. I have made available a new version based on Lotus Forms Viewer 4.0.0.3 which will allow you to view, edit and print like before. The major difference is that the new version does not have or need Java to function. There are some drawbacks to this with newer forms but they will still load and can be modified.
The latest version can be downloaded here: http://aeonconcepts.com/lotus
Please Note: Unless drastic changes are made to revised forms that break functionality of this version, this should be the last release required. If future OSX versions break the functionality, an updated version will be released.

Creating a view and use the view in a model

Hi All,
I am new to OBIEE and i have a requirement that i have two fields to be added to a subject area. Since we can't add queries directly to a model, i have to create a view and then put the query in it and then use the view in that model.
I couldn't understand this much, if anybody could help me explaining in detail about the views and adding a query in it?
Thanks

Hi,
Please refer the screen short below link
http://imgur.com/b9sXS
Right click any of one physial table(RPD physical layer) -> Select Properties -> from the properties windows choose 'Select' as Table type ->
Please enable feature 'CREATE_VIEW_SUPPORTED' view just go to 'Features' tab and from the available option select 'CREATE_VIEW_SUPPORTED' is checked or not. If it is not checked then check the option.
can you explain your current model and scenario?
for example to you can use to fetch two fields from Subqueries,all trypes of joins(inner,left outer,right outer etc..,) its upto you case
e.x:fetching two tables columns mapping subquery:
SELECT column1, column2 FROM table1 WHERE column1 IN (SELECT column1 FROM table1
INTERSECT SELECT column1 FROM table2 )
SELECT column1, column2 FROM table1,table2 WHERE table1.column1 = table2.column1
Alternative there is feature call "mulitple subject area" method will work (Union,Union all etc..,)
Thanks

Passing values to an internal table and use it with the table painter

Hi,
I have seen this topic here before but the answers didn't help me. Maybe I,m doing something wrong.
The problem is that I defined the following structure on the |Types| tab of the |Global Definitions| section:
TYPES: BEGIN OF DETAILS,
       EBELP TYPE EKPO-EBELP,
       BSMNG TYPE EBAN-BSMNG,
       LFDAT TYPE RM06P-LFDAT,
END OF DETAILS.
Then defined the following definition on the |Global Data| section:
WA_DETAILS TYPE STANDARD TABLE OF DETAILS WITH HEADER LINE
The problem is that when I try to assign a value to one of the fields in the program code like this:
LOOP AT WA_EKPO.
     WA_DETAILS-EBELP = WA_EKPO-EBELP.
     WA_DETAILS-EMATN = WA_EKPO-EMATN.
     MODIFY WA_DETAILS.
ENDLOOP.
gives me the following error:
"WA_DETAILS" is not an internal table -the "OCCURS n" specification is missing.
Then if I add the "OCCURS 10" to the definition of the Global Data the error "OCCURS 10" is not expected.
How can I define, assign values and use as a parameter an internal table defined with types for use it with the table painter?

Hi,
if it is one record in wa_details. you can directly write as follows..
REPORT ZCR_TEST1                               .
TYPES: BEGIN OF details,
          ebelp TYPE ekpo-ebelp,
          bsmng TYPE eban-bsmng,
          lfdat TYPE rm06p-lfdat,
          ematn TYPE ekpo-ematn,
       END OF details.
DATA: wa_details TYPE STANDARD TABLE OF details WITH HEADER LINE,
      wa_ekpo    TYPE STANDARD TABLE OF details WITH HEADER LINE.
wa_details-ebelp = '1'.
append wa_details.
wa_ekpo-ebelp = '3'.
append wa_ekpo.
LOOP AT wa_ekpo.
wa_ekpo-ebelp = wa_details-ebelp.
wa_ekpo-ematn = wa_details-ematn.
modify wa_ekpo.
endloop.
Normally it wont be one record, so u need to put <b>read statement with key</b> in LOOP and ENDLOOP.

Configure WRT54G Wireless Router with PUBLIC IP address and use DHCP for internal computers

Hi,I have an Internet online service with 5 public IP addresses. The router and the AP are connected to a switch. I would like to configure a WRT54G wireless router with one of this IP public Address and use DHCP (with private ip address) for the computers that will connect to the AP. As the AP is connected to the switch it is possible that other wired computers that are connected to the same switch can obtain an IP address from the DHCP ?
Thansk in advance

Thanks for your help. Please correct me if Im wrong. After connecte the equipments the way you suggestI setup a static IP address (The public IP) in the WRT54GI enable DHCP in the WRT54G with a range from 10.10.0.100 to 10.10.0.200 (as an example) The gateway is the Public IP address right ? How do I route the 10.10.0.x addresses to the public IP address. Thansk again

Loop using index read ( internal table)

Hi,
I thought of impelementing loop at ITAB using read statements, Here it goes.
REPORT Z_LOOP_IMPROVE.
DATA : T_OUTPUT TYPE STANDARD TABLE OF MARC WITH HEADER LINE,
L_TABIX TYPE SY-TABIX.
DEFINE ILOOP.
DO.
IF SY-INDEX EQ '1'.
READ TABLE &1 WITH KEY &2 = &3 BINARY SEARCH.
IF SY-SUBRC <> 0.
EXIT.
ENDIF.
ELSE.
L_TABIX = SY-TABIX + 1.
READ TABLE &1 INDEX L_TABIX.
IF SY-SUBRC NE 0 OR &1-&2 NE &3.
EXIT.
ENDIF.
ENDIF.
END-OF-DEFINITION.
DEFINE IENDLOOP.
ENDDO.
END-OF-DEFINITION.
DATA : T1 TYPE I, T2 TYPE I.
SELECT * FROM MARC INTO TABLE T_OUTPUT.
SORT T_OUTPUT BY WERKS.
GET RUN TIME FIELD T1.
ILOOP T_OUTPUT WERKS '0001'.
WRITE : / T_OUTPUT-MATNR, T_OUTPUT-WERKS.
IENDLOOP.
GET RUN TIME FIELD T2.
T2 = T2 - T1.
WRITE : / T2.
*C----
But sadly it takes more time than a normal loop with
where condition.
can anyone suggest some ideas to improve execution speed?

You can use a binary read to get the first record. Then read each record sequentially until you have proccessed all the records that meet your critera. You will have to have the internal table sorted so that the binary search and subsequent reads will work:
      READ TABLE itab WITH KEY
        field = whatever
        BINARY SEARCH.
      IF sy-subrc = 0.
        itab_index = sy-tabix.
        DO.
          IF sy-subrc = 0.
            IF itab_data-field = whatever
              itab_index = itab_index + 1.
              READ TABLE itab_data INDEX itab_index.
            ELSE.
              EXIT.
            ENDIF.
          ELSE.
            EXIT.
          ENDIF.
        ENDDO.
      ENDIF.
