In SAP Payroll, the standard personnel calculation rule XMOD is used to set various employee groupings, known as modifiers, for subsequent processing. The modifier MODIF 2 is specifically designated as the "Valuation Basis Grouping". This grouping is used by payroll functions and operations to read constant values, such as amounts or numbers, from the "Constants for Valuation" table (VT510J). Rule XMOD typically sets this modifier based on the employee's pay scale area, allowing for different constant valuations for different employee groups.

A. MODIF T: This modifier is used for the Time Wage Type Selection grouping, which determines wage type generation based on time data (Table T510S).

B. MODIF D: This modifier is used for the "Differentiation of Payments" grouping, which controls how payments are processed (Table T510C).

C. MODIF 1: This modifier is the "Pay Scale Grouping for Allowances," used to determine wage type permissibility and valuation based on pay scale structure (Table T510A).

Standard Personnel Calculation Rule XMOD:

Reference: In the documentation for the standard rule XMOD

it is explicitly stated: "The system sets modifier 2 for the valuation of constants (table T510J)." This directly links MODIF 2 to the VT510J table.

Valuation Bases:

Reference: The documentation on valuation bases explains that constants from table T510J are read using a specific grouping. This grouping is set in the personnel calculation schema using rule XMOD with the parameter MODIF 2.

3. SAP Customizing Implementation Guide (IMG):

Reference: Within the SAP system

the documentation for the IMG activity Payroll -> Payroll: International -> Basic Settings -> Valuation Bases -> Define Constant Valuations describes the configuration of table VT510J. The documentation for the "Constant val. grouping" field (KONST) specifies that its value is determined by the employee grouping for valuation bases

which corresponds to MODIF 2 set in rule XMOD.
