Structure, NODE, VALUE, and FUNCTIONAL MAPPINGS
Guys -
I am a novice to XI. But, I guess as per my understanding this is what I think. Please advis me if you have better opinion that would justify this answer in certifrication.
XI by definition supports only the following 4 mappings types:
Message (Graphical), XSLT, JAVA & ABAP
However, first in Element cardinality addresses something called NODE MAPPING which describes as follows:
Mapping of Non Mandatory Nodes (minOccurs=0)
====================================
1. If a non mandatory node contains elements with minOccurs>0, these elements becomes mandatory after their parent node is assigned
2. Assignment of element is not sufficient
3. Node has to be 'created' by assigning a suitable source node/element
Therefore, as per this discription, I believe NODE mapping a valid for CERTIFICATION
Secondly, as per my understanding of message mapping, we map source and target STRUCTURES here. Does not this mean STRUCTURE MAPPING? Please confirm?
Thirdly, You experts all must have done Value Mappings in your projects and there is no need for me to describe more about it. Can not we consider this as a valid answer for CERTIFICATION?
Last but not least FUNCTIONAL MAPPING; I am not sure why this option is here? May be this is just to add confusion. On the otherside, it make sense if we consider including functions (both standard and user-defined) in our mapping. Does this make sense being a valid Mapping at all?
In other words, let me ask you all experts; Is this a direct or indirect question? If it is direct then we should turn down all the options. If indirect, may the first 3 are correct or all four.
Therefore, I rely on your guys for you input. Please provide your valuble analysis.
Thanks
Hi Sudarsana,
The types of message mapping viz. graphical, ABAP, java and XSLT - are the features of XI.
On the other hand, the types - structure mapping and value mapping - are general concepts. Any integration tool should support these.
<b>Structure Mapping</b> is not very much concerned which values are being mapped. It is more concerned about the structure of source and target elements.
It can be of two types (these don't have formal names as such)
1) Mapping values of some source elements to some target elements
e.g. source has element <fname> which is directly mapped to element <FirstName> in the target.
2) Mapping values after changing the element structure
e.g. source is
<name>
<fname> --- </fname>
<lname> --- </lname>
</name>
And target is
<fullname> --- </fullname>
So here we concatenate source elements and map to target.
<b>Value Mapping</b> concentrates on the actual values that are being mapped.
Sometimes the requirement is like although source and target strcutres are similar, values need to be translated into another set and then mapped.
e.g. we have an element called <TravelClass> in both source and target element.
Now assume that source message uses codes such as 1, 2 etc. for this element. However, the target mmay expect strings values such as 'business', 'economy' etc. for this element.
In such cases, we use value mapping. Essentially we achieve the following translation:
1 -
> business
2 -
> economy
In graphical mapping we have a standard function called ValueMapping to define a simple table like one above.
Finally, the term 'Functional Mapping' is given only to confuse the people
Hope this clears your query.

Diif between Stored procedure and function
HI
I want all the differences between Stored procedure and function.
Even the basic diff is Procedure does not return any value and Function must be...
Thansk In advance...1) Functions are used for computations where as procedures can be used for performing business logic That's an opinion on usage not an actual difference.
3) You can have DML(insert,update, delete) statements in a function. But, you can not call such a function in a SQL query.Not true. As User defind functons limitations we can use a function that issues DML in a SELECT statement, if it uses the PRAGMA AUTONOMOUS_TRANSACTION.
4) Function parameters are always IN, no OUT is possibleEasily refutable...
SQL> CREATE OR REPLACE FUNCTION my_f (p OUT NUMBER) RETURN DATE
2 AS
3 BEGIN
4 p := to_number(to_char(sysdate, 'DD'));
5 RETURN sysdate;

Stored Procedure :supports deffered name resoultion Example while writing a stored procedure that uses table named tabl1 and tabl2

Difference between procedure and function
hi
please give solution to below discussion:
Interviewer: What is the difference between Procedure and Function ?
Myself: Procedure may or may not return a value and can return multiple values and Function must return a value.
Interviewer : Can function return multiple values ?
myself: Yes, It can return multiple values.
Interviewer: Then, there is no need to use procedures any more, according to your previous answer (function can return multiple values) "we can do all the things by using procedures by using functions". Then why there is differentiation between procedure and function ?
myself : no reply (simply frustated at this question)
The above is conversation between me and interviewer.
Please suggest me what would be my reply to above topic.
In one book i find that using functions we can return multiple values but it is poor programming practice.
why this is a programming practice ?
please suggest me solution
thanks in advance
prasanth as.Another difference is function must return something. There is no such restriction on procedure.In fact, a procedure CANNOT contain an expression in its RETURN statement.

Fetch attribute value of structure node
Dear All,
Please let me know is it possible to get the attribute name and attribute value of a structure node of a record model inside the program?
Can I give any name as the attribute name?
Regards,
Biju K GeorgeHi,
could you provide an example ?
I think you speak about using field-symbol.
--> get the attributes of a structure or a table --> same has field catalog for ALV
--> get the value of the attributes :
concatenante structure_mane attribute_name into w_field separated by '-'.
assign (w_field) to <field>
check <field> is assigned.
and <field> is the value of the attribute attribute_name of the structure structure_name.

Passing structures bet top level functions and DLL's
I need to access information stored in a structure(manipulated within a DLL)
from
the calling function. I defined the structure in the DLL include file and
#include "dll_include.h"
in the source code. The dll function manulipates the contents of the structure
as desired; however,
I can not get access to that structure from the calling function. If anyone
has any ideas, I would
certainly appreciate the help
PhilHi Phil
I think the key for this problem is simply to export that structure in the
dll that you want to access from the other app.
for example if you write in your dll_include.h file something like this:
typedef struct
ULONG ID;
CHAR Name[32];
} MY_APP_PERSON,*P_MY_APP_PERSON;
typedef void (*SET_PERSON)(void);
then in your dll source write:
#include "dll_include.h"
DLLEXPORT MY_APP_PERSON DllPerson;
DLLEXPORT void SetPerson()
DllPerson.ID = 3;
lstrcpy(DllPerson,"Daniel A.B");
In your other application which uses this dll write:
#include "dll_include.h"
static P_MY_APP_PERSON AppPerson;
static SET_PERSON SetPerson;
void main()
HINSTANCE dllHandle;
dllHandle=LoadLibrary("Persons.dll");
if(dllHandle)
AppPerson=(P_MY_APP_PERSON)GetProcAddress(dllHandle,"DllPerson");
SetPerson=(SET_PERSON)GetProcAddress(dllHandle,"SetPerson");
// Watch here with the debbuger the AppPerson structure state it
will probably containt dirty data
SetPerson();
// Now watch again the value of AppPerson and see it was changed
by calling SetPerson

Map Drop down to Context node with value and ID
I want to map a drop down to dynamic data. I have a table that is populated at runtime after a BAPI call. The structure is the same as if you used a simple type. i.e. Value and ID.
Hi Gordon,
Try out this
ISimpleTypeModifiable myType=wdThis.wdGetAPI().getContext().getModifiableTypeOf("MonthName");
//Set allowed values for this data type
IModifiableSimpleValueSet values=myType.getSVServices().getModifiableSimpleValueSet();
values.put("0","January");
values.put("1","February");
values.put("2","March");
values.put("3","April");
values.put("4","May");
values.put("5","June");
values.put("6","July");
values.put("7","August");
values.put("8","September");
values.put("9","October");
values.put("10","November");
values.put("11","December");
where MonthName is a value attribute of type string.

What is the values and meaning for parameter TCLAS in functions
what is the values and meaning for parameter TCLAS in functions like
HR_INFOTYPE_OPERATION
regards
janHi Jan,
Good Morning,
In TCLAS,
A, B , T will be there.
A- Master data and time data.
B- Applicant data.
T- Shift Schedule.
So, here we can say the default value will be integrated according to the above ABT.
Means in the feature ABKRS, if you give the default values for all the three, your payroll area will appear in Master Data and Time data. And in recruitment ( Appicant data ) and work schedules. Means you are getting ingrated to all the three.
And you can observe the feature PINCH also.
If you dont want to get integrate with Master data, then dont give the default value under the A- Master date and Time data. And if you want to get integrate with Recruitment , then give the default value under B.
I think u got the clear idea about TCLAS.
Dont forget to give the points
Thanks in Advance

Run query and get unexpected node values
Hi,
I am not seeing what should be expected when I run my query, and I am getting the display of the hierarchy nodes that I am not supposed to get access to. I checked my profile and I have the 0COSTCENTER as '*' and TCTAUTHH as ':' .
Where should I start finding why I am getting the node values displayed that I am not supposed to?
Thanks
WillWelcome to SDN.
I think you should better post it to the BI forum.
Did you try to use the user exit EXIT_SAPLRRS0_001 (extension RSR00001) to initialize the values? And for bypassing the selection screen, can't you define it in the query definition (if I remember well)? -
How can I get a list of values (one or more) used in the WHERE filter of stored procedures and functions in SQL Server?
How can get a list of values as shown (highlighted) in the sample stored procedure below?
ALTER PROC [dbo].[sp_LoanInfo_Data_Extract] AS
SELECT [LOAN_ACCT].PROD_DT,
[LOAN_ACCT].ACCT_NBR,
[LOAN_NOTE2].OFCR_CD,
[LOAN_NOTE1].CURR_PRIN_BAL_AMT,
[LOAN_NOTE2].BR_NBR,

LenfinkelHi LenFinkel,
May I know what is purpose of this requirement, as olaf said,you may parse the T-SQL code (or the execution plan), which is not that easy.
I have noticed that the condition values in your Stored Procedure(SP) are hard coded and among them there is a date values, I believe some day you may have to alter the SP when the date expires. So why not declare 3 parameters of the SP instead hard coding?
For multiple values paramter you can use a
table-valued parameter. Then there's no problem getting the values.
If you could elaborate your purpose, we may help to find better workaround.

Pipelined function which creates xml nodes,items and elements
Hi Everyone,
I am Vikas Kumar and i have written a pipelined function
which is returning a UDT which i have created in my database.
but when i am piping a row then there is error :
"Error: PLS-00306: wrong number or types of arguments in call to 'CLASEC_MENU_TYPE' "
i have created UDT as :
create type clasec_menu_type as object (menu_data xmltype);

pipe row(user_node);
end loop;
end;
compilation error is at the statement
pipe row (clasec_menu_type(root_node));
i think its conversion error but don,t know how can i convert root_node which has been defined with :
root_node xmldom.DOMNode;
Regards,
Vikas KumarHi,
Your type, clasec_menu_type, needs an argument of type XMLType. If you want to create instance of XMLType, you have to pass it varchar2, clob or XMLType.
So, think how will you convert xmldom.DOMNode to XMLtype or Varchar2 or clob.

How to use Call library function node for a function in dll with VOID data type
Hi All,
I would like to ask for your kind help,
I am facing an issue with the call library node.
I have a C++ function(stdcall), which has void as data type
error code XXXX(hwnd, lID, getValue, *void data1, *void data2)
the data1 and data2 types are always changing depending upoin the value of "getValue".
Primarily i can use call library node multiple times and adapt each node according to the data types of data1 and data2, and extract the values and use in the code. Here is no issue. Real question is:
My question:
How can i just use one time call library node and make a case depending upon the "getvalue", which will control the data type of data1 and data2. Here i really looking for solutions.
My trials:
i used varaints as input to the call libray node for data1 and data2, and selected Parameters in call libraby node as " Adapt to type". here labview just crashed.
i really appreciate your feedbackand suggestions.
Thanks

Clipboard02.jpg 103 KBA variant is a very specific LabVIEW datatype (really a C++ type object internally) and trying to pass that to a function, which excepts a flat memory pointer there, for sure will crash very quickly.
As to endianess, yes Unflatten will be able to adjust for endianess, which in this case however is most likely exectly NOT what you want. So make sure that the you select native type for the endianess input on Unflatten from String. LabVIEW internally works with whatever is the native endianess, as will most likely your C++ DLL. The platform independent big endian format does only come into play when you receive data streams over some streaming interface like a network connection. Here it is desirable to use an endian format that is independent from the actual platform that generates and consumes the data stream. LabVIEWs default endianes is big endian here.
But as long as you pass data directly to native components like DLLs there is no difference in endianess between what LabVIEW uses and what those components use.

How can I include CDATA in the node-value?
Hi Experts,
Via XI I map an incoming mail message to an outgoing XML. To be sure to not run into problems, I want to put <![CDATA[ and ]]> around the node-values.
Currently, I just do this in my message-mapping via a concatenate. The result LOOKS fine, but the XML-parser on the receiving application treats the CDATA as part of the total string and not as an indicator to accept every charachter within the node-value.
How can I put this CDATA around the node-values in a correct manner?
Thanks for your help!

Read a XML node value/attribute value from a CLOB
Hello,
I can write SQL/ - PL/SQL "straightforward" but now I have a problem what is to big for me. I hop that someone can help.
We create by code a xml structure and write these into the oracle database CLOB field. I'm sorry to say that a xml text structure is written into a clob in stead of a xmltype field. (it's a design failure?) It's a large xml structure. I believe I can't attach a file so I put at the end of this discussion a light example of the xml structure.
It's a xml with quartervalue's, so there are 35040 detail rows (24h * 4 * 365days). I want to accumulate the the attribute Amount value 9. The amount value is in the Detail node a attribute but at the end you can see that for the DST are also 4 value's, but these are not attribute value's but node value's. (In this case it are four value's in some cases there is one DST amount value.
Can somebody help me how to accumulate all the detail attribute value Amount with the node value Amount of the DST tag?

</Message>From what I know, extracting the "Amount" values in the Details section and the "Amount" values in the DSTS section would be two different SELECT statements.
Both of these will use XMLTable() to extract the values.
BTW - If you need more information on this, post up in the XML/XML DB forum section for more complex help. (eg getting YEAR with the DSTS Amount values)
as far as XML size goes, I've seen oracle handle a 100MB XML document without problems.
(just understand, it will be 'slow')
This one will give you the Amount values from the DSTS section:

Replace the XMLTable() with the one below to get the Amount from the Details section:
