Hi All, difference btwen data selection and person selection period in ldb

Hi All, difference btwen data selection and person selection period in ldb -pnp
If possible provide with an example .Its Urgent pls.

Hi,
Difference:--
Data Selection Period
The data selection period enables you to specify the period in which employee data records are read. Only records which overlap with the specified period by at least one day are selected. To define an interval, enter the start date in the left column and the end date in the right column
Person Selection Period
When you enter a person selection period, the system selects only those employees who are members of the enterprise on at least one day in the specified period. These are persons with a valid Organizational Assignment (0001) record. Entries in the standard selection options fields limit the personnel numbers that are selected. You can specify an interval by entering the start and end dates in the left and right columns respectively.
Selection criteria in PNP are just used to determine the pernrs which meet them. For these pernrs then all wanted data is selected. This data then is not checked against this criterias.
An Example:
Pernr 4711 has benn assigned to costcenter 10 from 01.01.2004 until 31.12.2004. On 01.01.2005 costcenter changes to 20.
If you now select all employees with costcenter 10 and list their costcenters, you will get both costcenters 10 and 20.
Most reports which use PNP have to sets of date-ranges:
- Person selection period that controls selection of pernr.
- Other period that controls selection of data.
If you set person selection period in above example to 01.01.2004 and other period to 01.01.2005 and select costcenter 10 you will in fact get employee 4711 with costcenter 20 shown.
Same effect with org-unit or any other selection criteria.

Data selection and Person selection

Hi all,
What is the difference between 'Data selection' and 'Person selection' in PNP screen.(PNP logical database)
I searched so many . But couldn't find appropriate one. Still confusing.
Can any one explain me with example?
must use both at a time or any one selection is enough?
Which situation use 'Data selection' and which situation use 'Person selection' ?
Thanks in advance.

thanks for all reply.
I have one pernr 700098
Hiring date : 01.01.2008 - 16.08.2008
firing date : 17.08.2008 - 31.12.9999
I developed a customized report using PNP LDB.
If , I entered 01.01.2008 - 31.12.2008 in 'Data selection'
              3 in employee status( active)
or
I entered 01.01.2008 - 31.12.2008 in 'Person selection'
              3 in employee status( active)
If , I entered 01.01.2008 - 31.12.2008 in 'Data selection'
              0 in employee status( active)
or
I entered 01.01.2008 - 31.12.2008 in 'Person selection'
              0 in employee status( active).
In above all cases picking the same record. what is the use of PNP screen?
after 'GET PERNR' pernr structure get the value of latest record from infotype P0000.ie firing record. Because it doesn't bother the status.
For below case picking the proper one.
If , I entered 01.01.2008 - 16.08.2008 in 'Data selection'
              3 in employee status( active)
or

Plz any one clear me.
Thanks.

Difference between data selection period and personal seletion period

Hi
Experts ,
ples Expline ,
Difference between data selection period and personal seletion period. to Data screening .

Data selection period means
For example if u given any period,
here we are checking whether data is valid in this period.
Personal selection period means
we are checking whether person is valid in a given period.
Example is:
For example if the employee resigned in a company on 15th of month.
He can get the salary only at the end of month it means his data is avilable upto end of month.
But when you consider his status from 16th to end of month
the person is not available.
So when u given date(16th to end of month) in data selection period is showing that person data is avilable.
But when mention that date in person selection period it is showing no person is avilable.

Difference between data form and data grids

Can anybody tell me what is the difference between data form and data grid.
Regards

data forms have restricted access. user can not access all the dimension and members, based on his role and authentication can access the form.
data grid r used for calculation, currency translation and coslidation and it consists of menu of options for diffrent consolidation based on cell status.
data grid can have line item information, description and cell status information.

Difference between Data Grid and Data Forms

Hi all,
What is the difference between data grid and data forms.

Data entry forms are pre defined and are generally used to manually input data into reporting (financial statement) schedules.
They can also be used for reviewing purposes and it gives users a presentable / and consistent format to view data in Hyperion.
Data grids are the equivalent of pivot tables in excel. It should be used for ad hoc purposes to view / analyse data in whatever form you choose. The user has the flexibility to choose what they see in the rows, columns and page dimensions.
One of the main differences between data entry forms and data grids is that you can’t export data grids to excel whereas you can with data entry forms. Other differences are:
1. Run consolidation, translation, promotion from data grids but not in data entry forms.
2. You can link other data entry forms to a data entry form
3. Data entry forms offer greater formatting options than in data grids i.e. colours, fonts, bold, italics.
At the end of the day, they are similar and there is no reason why you can’t have (use) both. It all depends on your local needs on how best you use both.
I hope above information helps.

Difference Between Data Type and Data Object

Difference Between Data Type and Data Object

hi magesh
Data types can be divided into
elementary,
reference, and
complex types.
Elementary Types
Elementary types are the smallest indivisible unit of types. They can be grouped as those with fixed length and those with variable length.
Fixed-Length Elementary Types
There are eight predefined types in ABAP with fixed length:
Four character types:
Character (C),
Numeric character (N),
Date (D),
and Time (T).
One hexadecimal type:
Byte field (X).
Three numeric types:
Integer (I),
Floating-point number (F)
and Packed number (P).
Variable-Length Elementary Types
There are two predefined types in ABAP with variable length:
STRING for character strings
XSTRING for byte strings
Reference Types
Reference types
describe data objects that contain references (pointers) to other objects (data objects and objects in ABAP Objects).
Data Types
1) As well as occurring as attributes of a data object, data types can also be defined independently.
2)You can then use them later on in conjunction with a data object.
3) The definition of a user-defined data type is based on a set of predefined elementary data types.
4) You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary.
5) You can use your own data types to declare data objects or to check the types of parameters in generic operations.
Data Objects
1)Data objects are the physical units with which ABAP statements work at runtime.
2) The contents of a data object occupy memory space in the program.
3) ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type..
4) For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
5) Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type).
6) You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures).
7) As well as fields in the memory area of the program, the program also treats literals like data objects.
hope this helps u,

Differences between DATA TYPE and DATA OBJECTS

I am new to ABAP,I want to know the differences between DATA TYPE and DATA OBJECTS with some examples.
please help me regarding this.

Hi Ashish,
Data Types:       Are pure descriptions.
               No memory is associated with data types.
               Describes the technical properties of data objects.
EX.
1.     C-CHARACTER
2.     D-DATE
3.     F-FLOAT
4.     I-INTEGER
5.     N-NUMERIC TEXT
6.     T-TIME
7.     P-PACKED NUMBER
8.     X-HEXADECIMAL
9.     STRING-Variable length string.
10.     XSTRING-Variable length byte string.
Data Objects: Are created during runtime.
                They cannot exist without the data Types.
                Occupies memory space.
EX:
1.     INTERNAL DATA OBJECT- Internal Data objects
     LITEERAL- A literal has a fixed value.Ex: WRITE:u201DWORK HARDu201D.
     VARIABLES: Data statement is used to create variables.
EX.DATA: NUM TYPE I.
NUM: VARIABLE defined by data statement.
EX: DATA: PRICE LIKE NUM.
     CONSTANT-It is a data object, which contains a constant value throughout the program.
Can be declared in program by using CONSTANT statement.
EX:CONSTANT: INT TYPE I VALUE 15.
2.     EXTERNAL DATA OBJECT: Are defined in tables i.e In ABAP/4 dictionary you can access this data from table.
         EX: TABLES: SFLIGHT
          DATA: SEATS LIKE SFLIGHT-SEATSMAX.
3.     SYSTEM DEFINED DATA OBJECTS:Space & system variables like SY-UNAME,SY-DATUM, SY-REPID.
4.     SPECIAL DATA OBJECTS:
     PARAMETERS: Are Variables ,which can accept value from user.
      SELECTION SCREEN : Are special internal tables to accept value ranges from user.
3 APPROACHES TO DEFINE DATA OBJECTS.
1.     ELEMENTARY TYPES
DATA: Customer _Name (25) TYPE C,
               Vendor_Name (25) TYPE C.
2.     REFRENCE TO AN EXISTING FIELD:
DATA: Customer _Name2 (25) TYPE C,
              Vendor_Name2 (25) LIKE Customer_Name2
3.     REFRENCE TO NON-ELEMENTARY TYPE:
TYPES: T_NAME (25) TYPE C
DATA: CUSTOMER_NAME TYPE T_NAME
               VENDOR_NAME TYPE T_NAME
4.     RECORD-Information in rows & columns.
DATA: BEGIN OF BOOKING,
                                ID (4) TYPE C,
                                FLIGHT_DATE TYPE D,
                                NAME LIKE CUSTOMER_NAME,
                                END OF BOOKING.

Difference between Data staging and Dimension Table ?

Difference between Data staging and Dimension Table ?

Data Staging:
Data extraction and transformation is done here.
Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
Cons: Staging tables need space hence need memory space
Dimension Table:
tables which describes/stores the attribute about specific objects
Below is star schema which has dimension storing information related to Product, Customer etc..

All differences between a function and a procedure.

What are All differences between a function and a procedure.

What are All differences between a function and a procedure.This is basic procedural programming fundamentals that you should learn at school.
A function is a procedure that returns a value (of the type defined in the function declaration) using the RETURN statement at the terminal point of the processing code.
That's the only difference.
In terms of SQL, procedures cannot be used within SQL and functions can, but only if the function does not contain any OUT or IN OUT parameters and the return type is of a supported SQL type.

Difference between Data Provider and extractor.

Hi
Can someone help me in understanding difference between data providers and data extractor.
I have gone through some documents but not able to get the exact difference between them.
What is the exact role of data provider and extractor with respect to sap solution manager.
Is data provider== Data extractor?
Thanks,
Vijay

Hello Vijaya,
From my perspective the Data Providers are responsible for collecting metric values from the monitored objects on the managed sources systems and sending these to the Solution Manager Monitoring and Alerting Infrastrucure.
Data extractors on the other hand are the reporting objects which are defined on the BW part of Solution Manager and can be enabled by configuring some monitoring scenario's. Once these data extractors are enabled, they will use the data from the "Data Providers" (see above) to setup nice BW reportings on the Solution Manager monitoring dashboards.
I hope this answer helps you.

Difference Between data target and infoprovider

Hi Experts,
I am new to BW
What is the difference between data target and infoprovider
Thanks and Regards,
saveen

Hi Saveen,
InfoProvider is an object on which BEx queries are created. It provides information (data) to the queries when they are executed. InfoProviders may contain data (like cube) or may not contain data (like multiproivder and InfoSet).
Data Target is an object to which you will load the data, like cube, ODS or InfoObject. But it is not necessary that each data target is an InfoProvider...like you may have ODS objects that are not enabled for reporting, but you are loading data to them for staging purpose.
Hope this helps...

Difference between Data-centric and Document-centric use

Hi,
Can someone suggest what exactly is the difference between Data-centric and Document-centric use and examples if any.
Thanks in advance.
Chaitanya

Maybe it helps if you look at it this way...
Document centric: document centric use of xml data is data that you always use in its complete form. If you want to use the data, then you always will retrieve it as one entity or you save it as one entity. You are not interested in the xml data / information inside this "package" / document, you are only interested in its total form. Lets say, you have an invoice which can be printed on one sheet of paper. This paper that contains you data, will always be treated in a document driven way, that is, in its total representation: information containted on a sheet of paper (document).
Data centric. data centric use of xml, is usage of data were the main interest point is focused on only pieces of the total set of xml data within a document. So instead of being interested in the whole invoice, you only are interested in information like "amount of money to be payed" or "invoicenumber".
Handling of XML data comes with (hidden) costs. Knowing how your data will be used, has to be used, is one of the first steps in designing you environment (and will have an big impact if you choose poorly). For instance, if you know that your data will always be handled (and must be stored) in a document driven way, then it will make sense to store it based on CLOB based XMLType storage. This will garantee best performance retrieval for your xml document. If you now that your xml data has to be stored so that it can be handled in a data centric way, then Object Relational XMLType storage. If conditions are setup properly data retrieval, inserts and updates will be more cost efficient then when based on CLOB XMLType storage.
There are more differences and "cost markers" when or when not to use CLOB, OR or for instance Binary XML. The first two chapters of the XMLDB Developers Guide for Oracle 11g will give you a good head start making some of those decisions. Be also aware that you probably will have to make compromises. The current state of XML, for example, doesn't have the final solution yet for a uniform storage method.
