In this step, you check the calculation of withholding tax. This is done in schema CHST, which calls schema CHS1 (tax with clearing). In both schemas, the following rules are accessed: CHSF, CHSH, CHSI, CHSJ, CHSK, CHSL, CHSM, CHSN, CHSO, CHSP, CHSQ, and CHSW.
Activities
Changes are not normally required. You should only make changes if you are familiar with the above rules and how they function.
Make a copy of the rule in question, rename the copy to create a customer rule, such as CHSF -> ZHSF, and then change the copy. Do not forget to change the schema so that it accesses the customer rule.
