Answer 1

hi subbu reddy,
The basic thing in HR is validity period of records, maintained in the master records.
we have difference between normal table and infotypes,
normal table do not contain the validity period for records but infotypes in HR have validity period for each record (we call it as time constraints).
for example:
employee working in an organization for ten years with different position,
        the infotypes contains records for the employee for ten years,
  personnel no : 1000         
  positions: supervisor,            begin date: 12.3.1997 to endate 12.3.1999
                 senior supervisor   begin date: 13.3.1999 to endate  06.5.2000
                  manager              begin date: 07.5.2000 to endate  08.9.2005
                  senior manager    begin date: 09.9.2005 to endate till date
is stored in the infotype for the employee.
these tables we call it as infotypes HR,
these infotypes r nothing but,
     1. its a screen to get the entry from the user,
     2. it contains structures
     3. its a module pool program
     4. its contains the user interface.
u go to transaction PA30
enter personnel no
infotypes r listed in the box
select personnel data (0002) infotype for ex (or) enter the infotype no directly
press button create now it will naviogate to a screen,
there u can find screen entry
give the begin date and end date validity of records,
when it crosses the validity periods it automatically delimits the validity
what ever values u enter in this screen will be stored in the appropriate infotype, here it is pa0002.(personnel data)
enter possible values and press save.
now goto se11
enter the infotypes no.pa0002...............where u created the entry in PA30
now u can able to view the records by entering the personnel no in the selection screen, now u can able to view the record saved in the PA30 trans.
Infotype
The data fields of HR master data, time management and recruitment are grouped logically into information types or infotypes for short.
Examples of infotypes are "Family/Related Person", "Organizational Assignment, "Basic Pay".
The following naming conventions apply to infotypes:
Infotypes 0000 to 0999 are used for HR master data
and sometimes for applicant data
Infotypes 1000 - 1999 for organizational management
Infotypes 2000 - 2999 for time data
Infotypes 4000 - 4999 for applicant data
Infotypes 9000 - 9999 for customers
     Time Constraint
A time constraint indicates whether more than one infotype record may be available at one time. The following time constraint indicators are permissible:
1: An infotype record must be available at all times. This record may have no time gaps. You may not delete the record last stored on the database because all records of this infotype would otherwise be deleted.
2: Only one record may be available at one time, but time gaps are permitted.
3: Any number of records may be valid at one time, and time gaps are permitted.
Other possible time constraint indicators are as follows:
A: Only one record may ever exist for this infotype. It is valid from 01/01/1800 to 12/31/9999. Splitting is not permissible.
View V_T582B Infotypes Which are Created Automically controls whether the system automatically creates the infotype record for an employee hiring or an applicant data entry action.
Infotypes with time constraintA may not be deleted.
B: Only one record may ever exist for this infotype. It is valid from 01/01/1800 to 12/31/9999. Splitting is not permissible.
Infotypes with time constraint B may be deleted.
T: The time constraint varies depending on the subtype.
Z: Refers to time management infotypes. The time constraint for these infotypes depends on the time constraint class defined in view V_T554S_I Absence: General Control. Collision checks are defined in view V_T554Y Time Constraint Reaction.
i have given the possible things for to u understand the infotypes begin date and end date.
i hope it will be usefull for u and give points
