Schema X000 is the standard international payroll schema provided by SAP. It serves as the primary, executable program for the payroll driver (RPCALCX0) for countries without a specific country version. It contains the fundamental processing steps for a payroll run, such as reading basic data, calculating gross pay, and determining net pay. It is designed to be copied and adapted to create country-specific payroll schemas. Its executable nature means it can be directly initiated to run a payroll calculation, unlike sub-schemas which are called from within a main schema.

B. XPPF: This is a sub-schema, specifically used in Great Britain payroll (PY-GB) for calculating pensionable pay. It is not a main, directly executable schema.

C. X010: This is a standard international sub-schema responsible for the valuation of gross wages and salaries. It is called by the main schema (like X000) and cannot be executed independently.

D. XT00: This is the standard international schema for Time Evaluation (transaction PT60), not for Payroll. While it is an executable schema, it belongs to the Time Management (PT) module.

Payroll: International (PY-XX)

Standard Schema for Payroll (X000): "The standard schema for the payroll driver is schema X000. This schema is used as a template for the country-specific schemas." This document establishes X000 as the main

executable template.

Time Management (PT)

Time Evaluation

Standard Schemas for Time Evaluation: "SAP provides the following standard schemas for time evaluation: Schema TM00... Schema XT00 for all other employees." This source clearly distinguishes XT00 as a Time Evaluation schema

not a Payroll schema.

3. SAP Training Course HR305 - Configuration of Master Data: This course material details the structure of payroll

explaining the difference between main schemas (like X000) that are run by the payroll driver and sub-schemas (like X010) that are called using the COPY function within a main schema to perform specific tasks. (Section: Payroll Schemas and Rules).
