Describes the sequence and contents of a country-specific payroll program (payroll driver) or time evaluation program (time evaluation driver). The personnel calculation schemas (from this point, abbreviated to schemas) define the basic process of payroll or time evaluation.

• The payroll driver runs the sequence based on the tasks specified by the schema. The standard system (client 000) includes an international payroll schema (X000) and different international and country-specific schemas. If payroll or evaluation schemas exist for a country, the country-specific indicators are used in the schema names in the standard system.
• The standard system includes a predefined international time evaluation schema (TM00) for the time evaluation driver.

• Subschemas are schemas accessed by the COPY function within another schema. They can be accessed from a main schema or subschema. Subschemas are used to carry out subtasks for Payroll and Time Evaluation. Subschemas need only be executable for test purposes.

A personnel calculation schema consists of the following elements (also referred to as schema elements from now on):
