In part two of his series on payroll schemas and rules, the author gives four tips on making new rules or changing existing rules. He covers how to stay compatible with SAP's standard schemas and rules, where to place custom rules in the payroll schema, how to salvage poorly written or incorrect custom rules, and when to create custom functions or operations, instead of using payroll rules.

In the first part of my series on the payroll schema and rule process, I showed you how to construct a simple and flexible payroll rule to calculate cost of living adjustment (COLA) payments for employees in R/3 Payroll.1 Now I’m going to give you four tips on making new rules or changing existing rules:

  • How to stay compatible with SAP’s standard schemas and rules
  • Where to place custom rules in the payroll schema
  • How to salvage poorly written or incorrect custom rules
  • When to create custom functions or operations, instead of using payroll rules

Stay Compatible with SAP’s Standard Schemas and Rules

When at all possible, create a new rule instead of modifying an SAP standard rule. When you modify a standard rule, problems can occur when you upgrade the system or apply HR Support Packages (HRSPs). For example, SAP might deliver some changes to its standard rules, and those changes will overwrite your modifications. A better practice is to copy a standard rule to a custom one and apply your changes there. This also means that when the system is upgraded or HRSPs are applied, you need to compare SAP’s standard rules and schemas to the ones you have modified, to see if there are any changes that need to be applied to your customized copies. You can use report RPULCP00 to see which objects, including rules and schemas, have been changed in each HRSP.
