CLIPBOARD_EXPORT from class CL_GUI_FRONTEND_SERVICES and string table - sh

Hi Gurus,
I have a problem with this method. When I'm passin to it table of strings I'm getting short dump. Something about RFC and XML. In my opinion this is error in SAP coding, but maybe I'm wrong. Has anyone this kind of problems with this method? Maybe there is a note to it?

Then, next time, you will ask the question clearly, because it's not what we all have understood!
> but I still think that this short dump is an effect of error in SAP coding so my question remains.
No, as I said, all functions based on frontend / OLE always used the C type. When OLE was issued in release 3, the STRING type didn't exist (available since 4.6). As OLE worked very well with C type, they had no reason to spend time to make it work for other types (there is always a risk that there are new bugs, I don't see why it should be considered as a bad policy).
You may simply argue that the documentation is not complete (or even inexistent sometimes), that's all.
In your case, we see that the CLIPBOARD_EXPORT method documentation is incomplete:
DATA (exporting) Contains a table of the data to be copied to the clipboard.
SAP always worked like that, and we abapers, always had to guess and spend time how these API work. But that's not a big deal usually (as for this one).

SQ01 Output From Joining VBSEGK and VBSEGS tables-1 line of output per DOC

I setup a query using SQ01 which uses tables VBSEGK and VBSEGS ( parked documents). The VBSEGS table has multiple lines per document in that there are multiple G/L accounts, cost centers and amounts in order to distribute expense acorss multiple cost centers from one vendor's invoice. When I execute the query only the first line item in the VBSEGS table appears and the remaining lines do not appear. Any insight to get all line items for each document from the VCSEGS table to appear will be appreciated.

Hi,
By default four links will be established between VBSEGK and VBESGS.
AUSBK
BELNR
GJAHR
BZKEY (This link should be removed for getting all the records)
However, you get the line items only if documents exist in both the tables. Apart from that, if two line items in one table and three line items in another table, you will get only three line items in the report. You need to select fields related to VBSEGK and VBSEGS tables.
Please provide me more information on your exact requirement. I can confirm you whether this is possible by way of query.
Best Regards,
Madhu

SELECTing from multiple rows and different tables

Basically, I have a table with a primary key and some other columns of data. The second table has a foreign key that points to the first table then has a columns with related data. I want to write construct a SQL query where one of the columns is the primary key from the first table and the second column is a concatenation of all the rows in the second table that have the same foreign key.
I need this in the form of one SQL statement so that I can use it to create a report in Application Express

Just in case my first post was a bit unclear.
My first table has a primary key, INTERACTION_ID, and several other columns of data.
My second table has a foreign key, INTERACTION_ID, and one extra column, USER_NAME.
There are several rows in the second table that share the same INTERACTION_ID as each interaction can have many user names. I want to construct a SQL query where I pull the interaction id in one column and concatenate all the relevant rows of USER_NAME as the second column.

Runing an exec from class Runtime and redirecting its output ...?..?

Hello!
I am trying to run a C exec by using th eRuntime class.
This works well ...
But, I want to redirect its output to my transcript.
This also works with small output (some lines !) ...
But the out put is up to 3000 lines, my program does
not continue. It is suspended in a waiting state.
I suspected that the buffer is filled, but there is still some lines to be written ...?
Anyone knows this problem and the solution ..?
Thanks by advance

You could try something like thisjava.util.List al = new ArrayList();
try {
     Process p = Runtime.getRuntime().exec("cmd.exe /c dir");
     BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
     String s = "";
     while ((s=br.readLine()) != null) {
          al.add(s);
     ListIterator li = al.listIterator();
     while (li.hasNext()) {
          System.out.println(li.next());
catch (IOException ioe) {}Mark

Foreign keys in SCD2 dimensions and fact tables in data warehouse

Hello.
I have datawarehouse in snowflake schema. All dimensions are SCD2, the columns are like that:
ID (PK) SID NAME ... START_DATE END_DATE IS_ACTUAL
1 1 XXX 01.01.2000 01.01.2002 0
2 1 YYX 02.01.2002 01.01.2004 1
3 2 SYX 02.01.2002 1
4 3 AYX 02.01.2002 01.01.2004 0
5 3 YYZ 02.01.2004 1
On this table there are relations from other dimension and fact table.
Need I create foreign keys for relation?
And if I do, on what columns? SID (serial ID) is not unique. If I create on ID, I have to get SID and actual row in any query.

Are you still designing your system? Why did you choose NOT to use a Star schema? Star schema's are simpler and have some performance benefits over snowflakes. Although there may be some data redundancy that is usually not an issue for data warehouse systems since any DML is usually well-managed and normalization is often sacrificed for better performance.
Only YOU can determine what foreign keys you need. Generally you will create foreign keys between any child table and its parent table and those need to be created on a primary key or unique key value.

I have no idea what that means. There isn't any way to tell from just the DDL for one dimension table that you provided.
It is not clear if you are saying that your fact table will have a direct relationship to the star-flake dimension tables or only link to them through the top-level dimensions.
Some types of snowflakes do nothing more than normalize a dimension table to eliminate redundancy. For those types the dimension table is, in a sense, a 'mini' fact table and the other normalized tables become its children. The fact table only has a relation to the main dimension table; any data needed from the dimensions 'child' tables is obtained by joining them to their 'parent'.
Other snowflake types have the main fact table having relations to one or more of the dimensions 'child' tables. That complicates the maintenance of the fact table since any change to the dimension 'child' table impacts the fact table also. It is not recommended to use that type of snowflake.
See the 'Snowflake Schemas' section of the Data Warehousing Guide
http://docs.oracle.com/cd/B28359_01/server.111/b28313/schemas.htm
>
Snowflake Schemas
The snowflake schema is a more complex data warehouse model than a star schema, and is a type of star schema. It is called a snowflake schema because the diagram of the schema resembles a snowflake.
Snowflake schemas normalize dimensions to eliminate redundancy. That is, the dimension data has been grouped into multiple tables instead of one large table. For example, a product dimension table in a star schema might be normalized into a products table, a product_category table, and a product_manufacturer table in a snowflake schema. While this saves space, it increases the number of dimension tables and requires more foreign key joins. The result is more complex queries and reduced query performance. Figure 19-3 presents a graphical representation of a snowflake schema.

Restrication on using sys and system tables.

Then he doesn't get what he "wants", he gets the minimum privs required to do his job. And it's the job of the DBA (presumably you) to enforce that policy. The technical issues are simple. The political ones are often difficult, but as a DBA that, too, is part of your job. It's YOUR job that will be on the line if you put the company's data at risk by granting someone excessive privileges on the database..

Removing punctuation from the beginning and end of a string

I am working on a project for a "spell checking" program. So far the StringHash class is made, and the dictionary is read into a hash table. Then the document to be checked is specified via command line, the document scans through each word and checks to see if it is in the dictionary, if it is do nothing, if it is not then display it to console. The problem I am having is with a method in the main class. The method (I will post what I have so far) is called removePunct. The method should remove any punctuation from the beginning and the end of the string, nothing from the middle. Here is what I have so far:
public static String removePunct(String word){
          StringBuilder wo = new StringBuilder(word);
          int x = (word.length()-1);
          if(!Character.isLetter(wo.charAt(0)))
               wo.deleteCharAt(0);
          if(!Character.isLetter(wo.charAt(x)))
               wo.deleteCharAt(x);
          return wo.toString();
Any help would be much appreciated, I'm pretty certain the solution is either something completely different, or something so simple that I just missed it.

The easiest way to do this is to just show you the actual file to be spell checked:
-- outline --
This directory contains Bison skeletons: the general shapes of the
different parser kinds, that are specialized for specific grammars by
the bison program.
Currently, there are only three supported skeletons:
- yacc.c
It used to be named bison.simple: it corresponds to C Yacc
compatible LALR(1) parsers.
- lalr1.cc
Produces a C++ parser class. It is still very experimental, and not
yet supported. Please, subscribe to [email protected].
- glr.c
A Generalized LR C parser based on Bison's LALR(1) tables.
These skeletons are the only ones supported by the Bison team.
Because the interface between skeletons and the bison program is not
finished, we are not bound to it. In particular, Bison is not
mature enough for us to consider that ``foreign skeletons'' are
supported.

What I need the spell checker to do is read each word, and strip any beginning or ending punctuation, e.g. (c) would become c. Pretty much punctuation consists of anything that is not a letter, hence the use of isLetter. I can easily modify the method to remove all punctuation using regular expressions, but I only want the beginning and end characters removed.
Example of words:
-yacc.c would become yacc.c and is not in the dictionary so it would be printed.

Read data from xml files and populate internal table

Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...

<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
             xmldata type xstring .
DATA: mr      TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
    WRITE: / struct_accontextdir-context_id,
           struct_accontextdir-context_name,
           struct_accontextdir-context_type.
    NEW-LINE.
    ENDLOOP.</pre>
<br/>
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
    Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
      CALL TRANSFORMATION id
        SOURCE shiv = t_internal_tab
        RESULT XML xml.
    CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
<br/>
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

DIFF: Field string ,Structure and Internal table declaration

Hai,
       what is the diference between Field string ,Structure in ABAP program and Internal table declaration and how it will work ?
Thank you
ASHOK KUMAR.

hi,
Look this u will get a good idea.
*& Report ZTYPES                                                      *
REPORT ZTYPES                                                  .
* Table declaration (old method)
DATA: BEGIN OF tab_ekpo OCCURS 0,             "itab with header line
ebeln TYPE ekpo-ebeln,
ebelp TYPE ekpo-ebelp,
END OF tab_ekpo.
*Table declaration (new method)     "USE THIS WAY!!!
TYPES: BEGIN OF t_ekpo,
ebeln TYPE ekpo-ebeln,
ebelp TYPE ekpo-ebelp,
END OF t_ekpo.
DATA: it_ekpo TYPE STANDARD TABLE OF t_ekpo INITIAL SIZE 0,      "itab
      wa_ekpo TYPE t_ekpo.                    "work area (header line)
* Build internal table and work area from existing internal table
DATA: it_datatab LIKE tab_ekpo OCCURS 0,      "old method
      wa_datatab LIKE LINE OF tab_ekpo.
* Build internal table and work area from existing internal table,
* adding additional fields
TYPES: BEGIN OF t_repdata.
        INCLUDE STRUCTURE tab_ekpo. "could include EKKO table itself!!
TYPES: bukrs TYPE ekpo-werks,
       bstyp TYPE ekpo-bukrs.
TYPES: END OF t_repdata.
DATA: it_repdata TYPE STANDARD TABLE OF t_repdata INITIAL SIZE 0,   "itab
      wa_repdata TYPE t_repdata.                 "work area (header line)

Read data from MDM For Lookup and Flat table using MDM ABAP API

Hi,
I have requriment to read data from MDM from FLAT and Lookup table using MDM ABAP API. My design is like this ,
I have one ITEMS (Main table in MDM) and inside that i have one Lookup flat table ITEM_TYPE , my requriment is to read Item number and its related Item type.
From ABAP.
Please help if any body has any idea.
Regards,
Shyam

HI Guys,
I found my solution by myself. Below is the solution , hope this will help others:-
Retrieve data from MDM using MDM ABAP API.
Step- 1. Create structure in SAP with the same name as that of MDM field code for MDM Main table.
Step-2. Create another structure in SAP having all lookup fields of MDM , fieldname in ECC must be same as that of MDM field
code.
Step-3.Create structure in SAP for individual lookup field(Single Field only)   with the same name as MDM Field code.
Step-4.
DATA: IT_QUERY            TYPE STANDARD TABLE OF MDM_QUERY, "MDM_QUERY_TABLE,
      WA_QUERY            TYPE MDM_QUERY,
      WA_CDT_TEXT         TYPE MDM_CDT_TEXT,
      IT_RESULT_SET_KEY   TYPE MDM_SEARCH_RESULT_TABLE,
      WA_RESULT_SET_KEY   TYPE MDM_SEARCH_RESULT,
      WA_STRING           TYPE STRING.
DATA:<Internal table> TYPE STANDARD TABLE OF <SAP Str Having all LOOKup Fields>
DATA: :<Internal table>TYPE STANDARD TABLE OF <SAP Str one LOOKup field>,
     <Workarea> LIKE LINE OF :<Internal table>.
*PASS LOGICAL OBJECT NAME.
V_LOG_OBJECT_NAME = 'Logical object name defined in Customization'.
Define logon language, country & region for server
WA_LANGUAGE-LANGUAGE = 'eng'.
WA_LANGUAGE-COUNTRY = 'US'.
WA_LANGUAGE-REGION = 'USA'.
TRY.
    CREATE OBJECT LR_API
      EXPORTING
        IV_LOG_OBJECT_NAME = V_LOG_OBJECT_NAME.
ENDTRY.
CONNECT to repository. Apply particular logon language info
CALL METHOD LR_API->MO_ACCESSOR->CONNECT
EXPORTING
    IS_REPOSITORY_LANGUAGE = WA_LANGUAGE.
*NOW PASS ITEM NO AND GET KEY FROM MDM.
CLEAR WA_QUERY.
WA_QUERY-PARAMETER_CODE = <MDM FIELD CODE>. "Field code
WA_QUERY-OPERATOR        = 'EQ'. "Contains
WA_QUERY-DIMENSION_TYPE = 1. "Field search
WA_QUERY-CONSTRAINT_TYPE = 8. "Text search
WA_STRING                = <Field Value>.
GET REFERENCE OF WA_STRING INTO WA_QUERY-VALUE_LOW.
APPEND WA_QUERY TO IT_QUERY.
CLEAR WA_QUERY.
*PASS ITEM NUMBER AND GET RELATED KEY FROM MDM.
TRY.
    CALL METHOD LR_API->MO_CORE_SERVICE->QUERY
      EXPORTING
        IV_OBJECT_TYPE_CODE = <MDM Main Table>
        IT_QUERY            = IT_QUERY
      IMPORTING
        ET_RESULT_SET       = IT_RESULT_SET_KEY.
CATCH CX_MDM_COMMUNICATION_FAILURE .
CATCH CX_MDM_KERNEL .
CATCH CX_MDM_NOT_SUPPORTED .
CATCH CX_MDM_USAGE_ERROR .
CATCH CX_MDM_PROVIDER .
CATCH CX_MDM_SERVER_RC_CODE .
ENDTRY.
Pass record id into keys.
LOOP AT IT_RESULT_SET_KEY INTO WA_RESULT_SET_KEY.
WA_KEYS = WA_RESULT_SET_KEY-RECORD_IDS.
ENDLOOP.
WA_RESULT_SET_DEFINITION-FIELD_NAME = <Look field name>.
APPEND WA_RESULT_SET_DEFINITION TO IT_RESULT_SET_DEFINITION.
CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE
EXPORTING
    IV_OBJECT_TYPE_CODE      = <MDM Main Table>
    IT_RESULT_SET_DEFINITION = IT_RESULT_SET_DEFINITION
    IT_KEYS                  = WA_KEYS
IMPORTING
    ET_RESULT_SET            = IT_RESULT_SET.
LOOP AT IT_RESULT_SET INTO
        WA_RESULT_SET.
*PASS KEYS INTO MAIN TABLE TO GET Structure for FALT or Look up Table
TRY.
      CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE_SIMPLE
        EXPORTING
          IV_OBJECT_TYPE_CODE = <MDM Main Table>
          IT_KEYS             = WA_KEYS
        IMPORTING
          ET_DDIC_STRUCTURE =<SAP Strct having all Look up fileds of MDM>
ENDTRY.
LOOP AT <SAP Strct having all Look up fileds of MDM> INTO <Work area>.
    CLEAR WA_KEYS.
    APPEND <Work area>-field name TO WA_KEYS.
    CALL METHOD LR_API->MO_CORE_SERVICE->RETRIEVE_SIMPLE
      EXPORTING
        IV_OBJECT_TYPE_CODE = <MDM Lookup table name>
        IT_KEYS             = WA_KEYS
      IMPORTING
        ET_DDIC_STRUCTURE   = <Single Structure in SAP For Lookup field>.
    READ TABLE <Single Structure in SAP For Lookup field>. INTO <Work Area> INDEX 1.
Here you can get the value of realted lookup fields associated with main table data.
ENDLOOP.
ENDLOOP.
LR_API->MO_ACCESSOR->DISCONNECT( ).

I would like to open a URL and extract tables from the HTML code of the web

Hi I have opened a URL say www.amazon.com and I would like to extract te tables in that particular web page would somebody out there help me with the code so that the output file displays only the relevant tables containing books and its prices dropping out all other data on the web page . My code for opening the URL goes here. Any quick help would be appreciated
import java.net.*;
import java.io.*;
class ConnectionTest {
public static void main(String[] args) {
try {
URL amazon = new URL("http://www.amazon.com");
URLConnection amazonConnection = amazon.openConnection();
DataInputStream dis = new DataInputStream(amazonConnection.getInputStream());
String inputLine;
while ((inputLine = dis.readLine()) != null) {
System.out.println(inputLine);
dis.close();
} catch (MalformedURLException me) {
System.out.println("MalformedURLException: " + me);
} catch (IOException ioe) {
System.out.println("IOException: " + ioe);
}

The quick and dirty way ( Not perfect and will be prone to errors ) :
As you read the lines using readLine(), look for the string "<table>" (Perhaps using String.indexOf ? -- Java API for class String -- http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html)
If the start tag is found, start dumping lines into a String (string concatenation), keep doing it until you find the end tag, using the method mentioned.
Also, you may want to consider the case where <table> or </table> may not be at the beginning of the line, so you may want to use String.substring to selectively extract part of the line that you want to keep.
Oh, and don't assume that the <table> tag is in lower case, and don't forget that there may be other attributes that are defined in the start and end tags.
I wouldn't recommend using this method other than a quick and dirty extraction. If you really want to do things the right way, use a HTML parser or use the Amazon Web Services as paulcw suggested.

How is the java.lang.StringBuffer class different from the java.lang.String

How is the java.lang.StringBuffer class different from the java.lang.String class?....

Read the API.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
"Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings."
Although when possible you should use StringBuilder instead of StringBuffer.
Always read the API at the very least before asking questions in the forums. Ideally you should do some google searching and poke around for an answer too. Otherwise you will get people barking at you.
