Concept of payroll driver Each country payroll version supported by SAP has a program called the "payroll driver" that calculates payrolls. For example, in the U.S., the payroll driver is RPCALCU0, in Mexico it is HMXCALC0, and in Canada RPCALCK0. Each one is different, but they share a common core of functionality.

The job of the payroll driver is to process payroll functions as specified in a payroll schema. These payroll functions each perform a specific job, for example - reading data from infotypes, calculating taxes, and processing wage types. Some functions process payroll rules. Rules are a collection of payroll operations. Each operation does a small unit of

get an amount.


Schemas are edited with transaction PE01, and rules Processing relationships with PE02. Functions and operations are maintained with transaction PE04. To view payroll results, use transaction pc_payresult (or in earlier R/3 releases go to Tools>Payroll result>Display in the Payroll menu). (See Figure 1.)

The standard payroll schema for a country can be derived from table t500l. If the country in table T500L has an X in the Old Naming Conv field, then the schema is HR Country Indicator plus 000. Otherwise, it is the ISO Code plus 00. So the U.S. has schema U000 and for Mexico it is MX00.

Header and Table Wage Type Concept

When calculating payroll, wage types are read from infotypes and

the Time Management cluster and stored in an internal table called

the Input Table (IT). See Table 1.)

In ABAP terms, this is simply an internal table. Various payroll

functions and operations can read and update data in this table.

Similar to ABAP internal tables, there is a header row. That header

row defines which row of data can be accessed by the payroll

operations. After manipulating the data in the header row, you can

save the row back to the IT, save it to another payroll table, or

ignore it. In Table 1 there are three wage types, and wage type

2100 is currently in the header row. After you are done with wage

type 2100, wage type 4200 is moved into the header row.

SCHEMA The payroll schema contains calculation rules to be used by the payroll

driver during payroll.

The personnel calculation schemas define the basic process of payroll or time

evaluation Schema is Basically collection of Functions and schemas to be

processed in sequential manner during payroll run.

Schemas can call other schemas within them using function COPY.

Transaction code for Schemas is PE01

Schemas are Country Specific

Report RPDASC00 can be used to search Schemas for Time and Payroll.

Edit Commands for Schema

D - Deletes a line

I - Inserts a line

C - Copies a line

DD - Indicates the start / end of a block to be deleted

CC - Indicates the start / end of a block to be copied

A - Places the block after the chosen line

B - Places the block before the chosen line

What a schema will do? A schema consists of the following parts:

Initialization

The system performs the following steps:

Updates the databases

Imports required infotypes

Gross calculation of pay


Processes basic data and time data

Queries off-cycle payroll runs

Reads payroll account of the last period accounted

Processes time data and calculates the individual gross values

Performs factoring

Net calculation of pay


Calculates net remuneration

Performs bank transfers


Functions in Schema

Functions are used in Schema. Used to perform business process

specific calculation within the Payroll Driver run.

Transaction Code : PE04

Functions can me created with customer development. Z*

Few examples for Payroll Functions:

PIT/PRT -Function PIT will process a particular wage type or all wage types in Input table/based on the parameter value

PRT -Function PRT will process a particular wage type or all wage types in Result Table based on the parameter value

COPY -Function copy is used to copy a subschema in main schema

IF & ENDIF - Used for conditional statement execution


BLOCK - Used to begin or end certain blocks in a schema

REFRSH -This function will refresh tables based on the parameter value

COM -This function is used to comment a line

SORT - This function will sort tables based on the parameter value

EXPRT - This function will export payroll results to cluster based on the parameter value

P0009/P0011 -These functions will be used to read infotype 0009 & 0011.


How to create a function? Transaction Code : PE04

Functions can be created with customer development. Z*


Indicator of interface relevance:

This indicator determines whether the function parameter specified is relevant for

the function interface (table T52BW).If the parameter is flagged, the respective

parameter value must be specified for all entries in T52BW.Otherwise, SPACE

should always be entered as the parameter value in T52BW.


Schema Structure The system processes these functions in sequence. A function must

be processed successfully before the next functions in the source

text can be processed.

Column D (Execution of function or subschema)

This indicator determines whether the function or subschema specified in a line of the source text is executed. If you enter an asterisk (*) in this field, you deactivate the function or subschema, in other words, the function or subschema is not included when the schema is executed.

Function

Most functions perform specific tasks that collect, process, or display data. There are also

Functions to control the process: conditions (IF...ENDIF) and loops (LPBEG...LPEND)

Functions to call subschemas (COPY)

Different functions to call personnel calculation rules


You can display a list of the functions available in the system. If you are in a personnel calculation rule and want to create an overview of all functions, choose the Maintain Functions and Operations transaction (PE04), and then choose F4 on the Name field. If you want to create a context-dependent list, select the function field and choose F4 Help.

Parameters

Functions can be accessed with up to four parameters. The parameters are used to define the function with greater precision.

How to create a Schema?

a program class(C-Payroll,T-time), Country grouping and if it is a

marked to run in payroll.


A sub schema in a main schema will be called with function


Creating Custom Schemas

Schema and Rule Naming Conventions :

Customer modified schemas and rules need to begin with Z. Many

customers simply replace the first letter of the standard schema with a

Z i.e., their modified copy of UAP0 becomes ZAP0.

Editor Documentation:

Documentation for the function, operation, schema, and rule editors is

available online at http://help.sap.com. Click on SAP R/3 and R/3

Enterprise and then select your release level and language. Then

navigate to the Human Resources>HR Tools section.
http://help.sap.com/


F1 Help:

In the schema and rule editors, place your cursor on a function or

documentation is available in the editor via the Goto>Documentation

menu. In the schema editor, the F4 key shows possible values for

each of the four parameters for whatever function is entered on

that line. The same documentation and more is available

via transaction PDSY.
