how to create, configure, and link a custom payroll calculation in Sage 300 People.
Sage 300 People lets you create custom calculations for payroll needs that standard calculations do not cover. These calculations link to payroll definitions and can return numbers, dates, or logical values based on how you set them up.
Once linked to payroll definitions, custom calculations affect payroll results for employees linked to the applicable company rule. Perform a recalculation after linking a new or updated calculation for the changes to apply.
