 When you want to use a wage type in infotype 8 (Basic Pay) that valuates your amounts indirectly from the pay scale table, you use the TARIF module. The TARIF module is used for indirect evaluation of wage types. Indirect evaluation defines the actual amounts for each wage type that the employee is eligible for according to his or her Pay Scale Grouping for Allowances1. When using pay grades for basic pay wage types, you will use indirect evaluation module 58710 to retrieve pay grade level and store it into AMT field of the wage type2. References = 2, 1
