Difference between SP datasource and object data source

Hi,
I have a requirement to query large list and display data in a view similar to SPlist view(Including Filtering, Sorting, Paging).
I have implemented the same using SPGridview and Object data source.
Can you please comment on the performance of the spgridview's(soritng, filterting and paging) using object data source and spdatasource.
Thanks,
Sunitha

Hi,
Kindly Prefer SPDatasource over Object datasource

Difference between busniess Event and object event

Hi All,
Can anyone explain to me what the difference between business event and object event in Beehive?
thanks

Business events are events that are exposed for integration with policies, audit, workflows, user notifications etc.
Object events are an internal-to-beehive system service that are consumed within Beehive Services and are not exposed for application or user consumption.

The difference between FIELD-SYMBOL and normal DATA TYPE

Dear experts,
Please see the example below, both are output the same result.
DATA: EXTERNAL_RECORD(4000),
      POSITION TYPE I,
      LENGTH TYPE N,
      ENTRY TYPE STRING.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
    EXIT.
ENDIF.
ADD 4 TO POSITION.
MOVE EXTERNAL_RECORD+POSITION(LENGTH) TO ENTRY.
WRITE ENTRY.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
    EXIT.
ENDIF.
ENDDO.
--OR It can be written as--
DATA: EXTERNAL_RECORD(4000),
      POSITION TYPE I,
      LENGTH TYPE N.
FIELD-SYMBOLS <ENTRY>.
EXTERNAL_RECORD = '0005Smith0007Edwards0005Young'.
DO.
LENGTH = EXTERNAL_RECORD+POSITION(4).
IF LENGTH = 0.
    EXIT.
ENDIF.
ADD 4 TO POSITION.
ASSIGN EXTERNAL_RECORD+POSITION(LENGTH) TO <ENTRY>.
WRITE <ENTRY>.
ADD LENGTH TO POSITION.
IF POSITION >= 4000.
    EXIT.
ENDIF.
ENDDO.
Is there any special circumstances we need to use FIELD-SYMBOL?
Why is FIELD-SYMBOL is introduce in the first place?
Kindly advice with example.
Thanks in advance for those who can help me on this.

HI,
You can use field symbols to make the program more dynamic. In this example the name of a table control is substituted by a field symbol. Thus you cal call the form with any internal table, using the name of the table control as a parameter.
Example
form insert_row
using p_tc_name.
field-symbols <tc> type cxtab_control. "Table control
assign (p_tc_name) to <tc>.
insert 100 lines in table control
<tc>-lines = 100.
Field symbols allow you to:
**     Assign an alias to a data object(for example, a shortened
        name for data objects structured through several hierarchies
        - <fs>-f instead of rec1-rec2-rec3-f)
**     Set the offset and length for a string variably at runtime
**     Set a pointer to a data object that you determine at runtime (dynamic ASSIGN)
**     Adopt or change the type of a field dynamically at runtime
**     Access components of a structure
**     (from Release 4.5A) Point to lines of an internal table
        (process internal tables without a separate work area)
Field symbols in ABAP are similar to pointers in other programming
languages. However, pointers (as used in PASCAL or C) differ from ABAP
field symbols in their reference syntax.
The statement ASSIGN f to <fs> assigns the field f to field
symbol <fs>. The field symbol <fs> then "points" to the
contents of field f at runtime. This means that all changes to the
contents of f are visible in <fs> and vice versa. You declare
the field symbol <fs> using the statement FIELD-SYMBOLS: <fs>.
Reference syntax
Programming languages such as PASCAL and C use a dereferencing symbol
to indicate the difference between a reference and the object to which
it refers; so PASCAL would use p^ for a pointer instead of p, C would
use *p instead of p. ABAP does not have any such dereferencing symbol.
**     In PASCAL or C, if you assign a pointer p1 to a pointer p2,
you force p1 to point to the object to which p2 refers (reference semantics).
**     In ABAP, if you assign a field symbol <fs1> to a field
symbol <fs2>, <fs1> takes the value of the data object to
which <fs2> refers (value semantics).
**     Field symbols in ABAP are always dereferenced, that is,
they always access the referenced data object. If you want to
change the reference yourself in ABAP, you can use the ASSIGN statement
to assign field symbol <fs1> to field symbol <fs2>.
Using field symbols
You declare field symbols using the FIELD-SYMBOLS statement.
They may be declared either with or without a specific type.
At runtime you assign a field to the field symbol using the ASSIGN
statement. All of the operations on the field symbol act on the field
assigned to it.
When you assign a field to an untyped field symbol, the field symbol
adopts the type of the field. If, on the other hand, you want to assign
a field to a typed field symbol, the type of the field and that of the
field symbol must be compatible.
A field symbol can point to any data object and from Release 4.5A,
they can also point to lines of internal tables.
The brackets (<>) are part of the syntax.
Use the expression <fs> IS ASSIGNED to find out whether the field
symbol <fs> is assigned to a field.
The statement UNASSIGN <fs> sets the field symbol <fs> so
that it points to nothing. The logical expression <fs>
IS ASSIGNED is then false. The corresponding negative expression
is IF NOT <fs> IS ASSIGNED.
An unassigned field symbol <fs> behaves as a constant with
type C(1) and initial value SPACE.
MOVE <fs>
TO dest     Transfers the initial value SPACE to the variable dest
MOVE 'A' to <fs>
Not possible, since <fs> is a constant
(runtime error).
To lift a type restriction, use the CASTING addition in the
ASSIGN statement. The data object is then interpreted as though
it had the data type of the field symbol. You can also do this
with untyped field symbols using the CASTING TYPE <type> addition.
The danger with pointers is that they may point to invalid areas.
This danger is not so acute in ABAP, because the language does not
use address arithmetic (for example, in other languages, pointer p
might point to address 1024. After the statement p = p + 10, it would
point to the address 1034). However, the danger does still exist, and
memory protection violations lead to runtime errors.
A pointer in ABAP may not point beyond a segment boundary. ABAP does
not have one large address space, but rather a set of segments.
Each of the following has its own segment:
*     All global data
*     All local data
*     Each table work area (TABLES)
*     Each COMMON PART
You should only let field symbols move within an elementary field or
structure where ABAP allows you to assign both within the global data
and beyond a field boundary.

Difference between reference variable and object ?

I am getting confused with reference variable and object ?
1. int a; // is a variable
2. Car c = new Car(); // is a object of car type
Suggest me what are the difference between the two.....

Can you actually point back to the original reference?Not clear what you're asking here. Nothing points to references. References point to objects.
Goodness, correct wording is as important as getting the syntax right, isn't it? ;-} What I was trying to ask is if it is possible to point back to the same String once you change the pointer on the variable?
And you answered my question succintly with the rest of your post. thanks jverd
>
String str = "abc";
str = null;'At this point, we've lost the reference to the original String object. However, at runtime, the VM will still be maintaining it in the constant pool. For any non-constant-pooled object, as we're writing our code, we'd have no way to refer to that object again. In this case, we are able to refer to the same object later in our code by simply using the same string literal. "abc" elsewhere in our code will cause the VM to give us a reference to that same pooled String. Same goes for Integer, etc. in the range -128..127.
However, it's not good design to rely on this. If your design requires you to later point to "the same object" (as opposed to any object of a compatible type and holding the same contents), then you should explicitly maintain a reference to it. In the case of Strings, you really shouldn't care whether it's the same object or not. All you care about is the character sequence that defines the String's state.

Hello Everybody,
Could anyone please tell me the difference between below two declarations:
Field-symbols: <lv_first> type any,
<lv_second> type data.
Edited by: Matt on Nov 6, 2008 1:34 PM

I will tell you where you can find the details;
1) Goto Tcode ABAPHELP ,enter "TYPE DATA" in the keyword and press ok,
2) In the Appearing list double click on the data, built-in generic type under sub-node ABAP Environment.

The difference between class, instances and object?

I've been reading a JAVA book and i've come accross terms such as class, instances and object. What I don't understand is why after creating a class, we have to create an object and then create instances? What's an object and instance anyway? I don't really understand the term. Can anyone pls help and explain it to me in an easier way to understand?
Thanks a lot.

A Class defines what attributes (properties) and methods a particular item will have.
Ex. You have a class person
public class Person
public void walk()
String name;
int age;
}An instance and Object are the same. When you create an instance of a class, you get an object of that class.
Person kevonline = new Person();You can then set kev's name, age, make him walk, etc... since these are defined in the class Person.

What are the differences between the old and new data flow technology?

I have seen many places mentioned the new data flow tech ( In BI7) are much different from the old one,, can anyone list a few differences?
Thanks

Hi Dylan,
An infosource can be used in the 7 flow model, but its purpose is completely different from the 3.x model.
In the 3.x model, the infosource consisted of 2 structures transfer and communication.
The transfer structure was where you specified which field in the datasource corresponds to which infoobject ie the field type.
You now do this in the datasource maintainence in 7.0 (the tabs called proposals and fields)
The communication structure was the structure which was available for uploading.
You can refer the link for the 3.x flow
[http://help.sap.com/saphelp_nw70/helpdata/en/90/64553c845ba02de10000000a114084/content.htm]
In the 7.0 flow, you generally use a DSO when you perform sequential transformations ie you want to change the data format or do some processing twice before you actually load to the final infoprovider.
The sequence in this case would be
Datasource -> transformation1 -> DSO -> Transformation 2-> DSO -> Transformation 3-> Cube
The disadvantage of doing this, is that the DSO will store data. To avoid this, you can use an infosource instead of a DSO.
You can refer the below link for using 7.0 infosources
[http://help.sap.com/saphelp_nw70/helpdata/en/7e/001342743eda2ce10000000a1550b0/frameset.htm]

What is the difference between function groups and Object Orientation

Hello all
I have read about this on the help.sap.com site, I still do not understand it completely, can some one explain me with a simple example please ? (Not the increment counter example please !).
Thanks a ton.
Rgds
Sameer

Hello Sameer
When you call a module of a function group for the first time in your program then the entire function group is loaded. However, this can happen only once within your report and all global variables within the function group will have the same values all the time (except they are manipulated via fm's).
In contrast, you can create as many instances of the same class as you want and all of them can have different global attributes. And all these instances are independent of each other.
On the other hand, if fm_A changes global attributes of the function group and fm_B reads these attributes then fm_B read the changed values.
Or in other words:
Function Group = can be instantiated only ONCE
Class = can be instantiated unlimited

Difference Between Current Day and fist day of the payroll period

Hi,
How do i find the difference between the current day and the first day of the payroll period with period parameter XX.
Operation VARSTFDYXX is used to decide if the current day is the first day of the payroll period. But is there any operation available to check the difference in exact number of days.
I know hrs=y is used to find difference between current day and a date specification record from IT0041, but i need to check difference between current day and first day from a payroll period parameter.
Any response is greatly appreciated.
Thanks,
Imaneul Rajiv

No! haven't seen it at all! Do I have to drain the battery completely and then charge it? I did that the first day I bought the phone and yet the stats are the same for me

Difference between 0FI_AP_30 and 0FI_AP_4 Data source

HI,
What is the difference between 0FI_AP_30 and 0FI_AP_4 Data source.
Thanks in advance

Hi,
In addition to above differences. Below is the functional difference between 0FI_AP_30 & 0FI_AP_4:
0FI_AP_4 gives you accounts payable line items in your report. Here GL account shows the balances of particular types of vendors/payables to which that particular GL account is been assigned.
And If subledger is activated in ECC, then by using 0FI_AP_30 you can get the break up of that particular GL balance according to vendors.
To make use of datasource 0FI_AP_30, subledger accounting must be activated in ECC.

Differences between Oracle BAM and Oracle BI and Question BAM Data Objects

Hi,
I have two questions.
1. Can someone tell me differences between Oracle BAM and Oracle BI?
My understanding about Oracle BAM is, we use BAM to build Dashboards or Reports.
We can also build DashBoards or reports using Oracle BI.
I am not able to understand why Oracle has two tools for same purpose?
Which tool is more powerful and user friendly(Oracle BI or Oracle BAM)?
2. Every time we plan to develop Dashboard or report in BAM, we need to create BAM ADC Data Object to store Data (i.e first step is to get data from external database or application and second step is to store data in BAM ADC data object).
My understanding is we have an extra step(i.e creating Data Object) in Oracle BAM to develop a report or DashBoard
I am wrong pl correct me?

DataSource - difference between ejb-location and location

Hi,
Does anyone know difference between ejb-location and location attribute specified in datasources.xml for an emulated datasource.
There are few connection leakage errors reported in log files though the connection and other database objects have been closed in finally block in all places.
So just wanted to find out whether specifying the same value for location as well as ejb-location is not the root cause of connection leakage errors.
Thanks in advance for any help.
Regards,
Smita

Smita,
Personally, I think you should make sure that all locations (in your "data-sources.xml" file) should be different -- although I can't tell you why.
According to the documentation, the "ejb-location" uses a connection pool and I exclusively use the "ejb-location".
Good Luck,
Avi.

Differences between BW3.5 and BW7.0 Realtime Data Acquisition

Hi,
Could any one explain me clearly the differences between BW3.5 and BW7.0 for Realtime Data Acquisition and also steps for creating it in BW7.0.
Eagerly waiting for your reply. Thanks in advance
Anan

You have to create tranformation in between your DSO and datasource.
If u have not done init of delta earlier, create Standard DTP and schedule init load.
If you did already, create or convert(if standard DTP already exists) Real time DTP. Now create infopckage with realtime field enable, and follow the steps of my blog on demanon from here onwards.
