HR ABAP - INFOTYPE TABLES & STRUCTURES

Infotype:

Group of related information bonded by time constraint is called infotype. Ii is represented with four digit number. Infotype are also called information types. Infotype is a collection of logical or business related characteristics of an object.  

*nnnn  = Info type number

*PA = Personnel Administration

*TM = Time Management

*PD = Personnel Development

P means previous results
O means old results
A means current results

Infotype Structure:

Each infotype is associated with the structures PAKEY, PSHD1, PSNNN& CI-PNNNN.

PAKEY: Set of key fields. All primary keys grouped under one structure.

PSHD1: Contains the control data like name of person who changed object and last changed. We change it enters in lock mode.

PSNNN: Contains the actual fields of that particular infotype. It is changed for different infotype.

CI-PNNNN: Custom infotype. It is optional structure.

Infotype Subtypes:

Some infotypes are again separated in different groups having same nature.

e.g.: subtypes of infotype address (0006) are

3-home address

5-mailing address etc.

There are two types of fields in an infotype. They are mandatory fields & optional fields.

Infotype Periods:

Every infotype has a specific validity dates (start & end dates). The validity period allows to maintain an employee’s data history. While updating an employee’s data, the earlier data is automatically delimited.

It collects data for all required fields into one table in SAP.
It can only be used for a limited number of infotypes (such as infotype 0014 and 0015).
Transaction : PA70 and PA71
In this tutorial , lets create Fast Entries for IT14.
In the SAP command prompt , Enter Transaction PA70

Select period radio button

Enter the From and To date of the new records.

Under Enter Personnel Numbers, Select one of the following:

Enter in Fast EntryScreen: You enter the personnel numbers directly into the fast entry data table.

How to view all Infotypes Saved for an Employee

You can view all infotypes saved for in SAP HR for a pernr using "Personnel File".
Personnel File stimulates browsing through employees personal data.
The personnel file facility is accessed using the following menu path: Human Resources => Personnel Management => Personnel Administration => HR Master Data => Personnel File or transaction PA10

The personnel file displays all of the infotypes to which data has been saved for a personnel number.
Infotypes are displayed in ascending numeric order and then sorted by their validity. They same display order applies to subtypes. They all appear after the respective infotypes
If several records exist for the same infotype, they are displayed one after another. The system then goes on to the next infotype. When it has reached the last infotype for which data exists SAP returns to the initial screen.
You can scroll backwards and forwards through the personnel file by using the Next Record function (or F19) and the Previous Function (or F18).

Personnel Actions

A Personnel Action includes all the necessary infotypes, displayed in a logical sequence, for which data must be entered for a particular HR event like hiring, termination etc.

In the SAP Command Prompt , Enter Transaction PA40.

The SAP Personnel Actions screen is divided into 3 sections:

Personnel Number: In this field, you enter the employee's personnel number, expect when executing the "Hiring" action, as it may be generated automatically by the system.

From: In this field, you enter the start date applicable to the personnel action.

Action Type: In this section, you select the appropriate personnel action.

To gain a clarity on  Personnel Actions , lets execute an  Hiring Action in SAP.

Enter the hiring date in the From field.

Select Hiring from the Action Type list.

Click to execute the transaction.

In the next SAP screen

The Start and to dates are defaulted in, check and maintain if necessary.

Check the Action Type is correct.

Enter the Reason for Action.

Enter  the Personnel Area.

Enter  Enter the Employee group.

Enter the Employee subgroup.

Click the Save Button. Personnel Number is automatically geenrated.

Once you click save the hiring Infogroup is activated. Every Infotype relevant to the Hiring action will appear one after each other. Once you have maintained each Infotype, validate your entries by pressing enter and save, save.

Time constraint: Time constraint means validity period of the record. In sap they are three types of time constrients mainly.

Time Constraint 1: An infotype record must be available at all times. Must have no gaps, no over lapping.

E.g. leaves quota like one day. We can’t take two types of leave.

·         For Infotypes falling under Time Constraint 1, it is mandatory for a record to exist, and only 1 can exist at any point in time.

e.g:0001, 0008, 0009

·         For example, Infotype 0002 (personal data).

Time Constraint 2: Only one record may be available at one time. May include gaps, no over lapping.

E.g. Loans. We can two types of loans at a time.

·         For Infotypes falling under time constraint 2, it is NOT mandatory for a record to exist, but only 1 can exist at any point in time.

e.g:0021.

·         For example, Infotype 0218 (membership insurance).

or

Infotypes 0019(Monitoring of Tasks):

Time Constraint 3: Any number of records may be valid at one time. May include gaps, over lapping. 

E.g. any number of valid records can’t exists at any one time.

·         For Infotypes falling under Time Constraint 3, it is NOT mandatory for a record to exist, but many can exist

e.g:0014

·         For example, SAP Infotype 0015 (additional payments).

Time Constraints 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 constraint A may not be deleted.

Time Constraints 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.

Time Constraints T: The time constraint varies depending on the subtype.For the Addresses infotype (0006), you can assign a different time constraint for each subtype. In this way, you can make sure that a main address always exists for the employee and you can also enter temporary residences, if necessary.

Time Constraints 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.

Time constraints are maintained in the view V_T582A.

The following time constraint indicators are permissible.

LDB:
Logical database is similar like a functional module, In ldb we have selection screen. In functional module no selection screen. The ldb is special type of ABAP program that combines the contents of certain related database tables and retrieve some related data and make it available to application programs. Alogical database can contain a maximum of 300 tables.

LDB’S in hrabap:

·         PNP

·         PNPCE

·         PAP

·         PCH

LDB components:

·         Standard Selection screen.

·         Data Retrieval.

·         Authorization check

Standard Selection Screen

1.      Date selection: Date selection delimits the time period for which data is evaluated. GET PERNR retrieves all records of the relevant infotypes from the database. When you enter a date selection period, the PROVIDE loop retrieves the infotype records whose validity period overlaps with at least one day of this period.

2.      Person selection: Person selection is the ‘true’ selection of choosing a group of employees for whom the report is to run.

3.      Sorting Data :( a) the standard sort sequence lists personnel numbers in ascending order.
(b)SORT function allows you to sort the report data otherwise. All the sorting fields are from infotype 0001.

4.      Report Class :( a) you can suppress input fields which are not used on the selection screen by assigning a report class to your program. (b)If SAP standard delivered report classes do not satisfy your requirements, you can create your own report class through the IMG.

Data Retrieval 

·         When you run your report, the logical database loads the personnel data for each employee into the main memory and makes it available for processing.

·         The entire history of each infotype is loaded into the main memory, that is all infotype

Authorization Check

·         The system first checks whether the user has an authorization for the employee in accordance with the criteria of organizational assignment. Employees for which the user has no authorization are not evaluated.

·         The system then checks whether the user is authorized to process the infotypes of the specified report. A list would be meaningless if the data were not evaluated completely.

LDB key points:

·         The standard program of ldb pnp is SAPDBPNP.

·         Addition of extras behaving LDB is PNPCE.

·         PNP is old ldb used to retrieve hr master data.

·         PNPCE used to retrieve hr master data but capable of concurrent employees.

MACRO:
It is one of the modularization technique. All hr related data will store in 'TRMAC' database table. Some macros in standard sap program 'DBPNPMAC'.

Needs of modularization:
Improve the structure of the program.
Easy to read the code.
Easy to maintain the code.
Avoid redundancy & promotes code reuse.

Standard HR Macros:

RP_PROVIDE_FROM_FRST:- This macro fetch the oldest (first) record from the infotype internal body to header for a given details.
RP_PROVIDE_FROM_LAST:- This macro fetch the latest (last) record from the infotype internal body to header for a given details.
RP_READ_INFOTYPE:- ThDirectly deals with infotype database table.

Note: IF PNP-SW-FOUND = 1. Use this condition to check the macro is successfully executed or  not

Process of Macro:

RP-READ-INFOTYPE A B C D E, where

A: Corresponds to PERNR which describes for which personnel number you require records.

B:  Corresponds to INFOTYPE which describes from which infotype you require records.

C: Subtype

D: Corresponds to Start date.

E: Corresponds to End date.

EXAMPLES:
RP_PROVIDE_FROM_FRST P0001 SPACE PN-BEGDA PN-ENDDA.
RP_PROVIDE_FROM_FRST P0001 1 PN-BEGDA PN-ENDDA.

Cluster:
All logs compressed & stored in binary format is called cluster. The system will store master data logs like employe create / employee delete. Any master data behind the screen is cluster. It has 3900 characters. RPUAUD00 use this standard program we find log changes details. It is header information & item information.
Header read: HR_INFOTYPE_LOG_GET_LIST
Item read:HR_INFOTYPE_LOG_GET_DETAILS

Payroll Cluster:

Payroll cluster enables you to view all the payroll related information for an employee at a single place. The information like, in which payroll cycle the employee lies, what is the run date & run time for a particular payroll, which is the active payroll, is quite easy to retrieve using payroll cluster.

Payroll Cluster Tables:

Payroll cluster tables combine the data from several tables with same keys into one record on the database.

• Cluster tables combine the data from several tables with identical ( or almost identical) keys into one physical record on the database.
• Data is written to a database in compressed form.
• Retrieval of data is very fast if the primary key is unknown.
• Cluster tables are defined in the dictionary as transparent tables.
• External programs can not interpret the data in a cluster table.
• Special language elements EXPORT TO DATABASE, IMPORT TO DATABASE & DELETE FROM DATABASE are used to process data in the clusters in the clusters tables.

Cluster Tables in SAP

PCL1- Database for HR work area; ( long text, etc.)

PCL2-Accounting Results ( time, travel expense & payroll )

PCL3-Applicant tracking data

PCL4-Documents, Payroll year-end Tax data ( change logs, etc.)

Database tables PCLN:

•  PCLN database tables are divided into subareas known as data clusters.
• Data clusters are identified by a two-character code. e.g. RU for US payroll result, B2 for time evalution result, TX for long text, LA for change logs.
• Each hr subarea has its own cluster.
• Each subarea has its own key.
