The SAP error message HRPSGB_ME303, which states "Wage Type MENI won't have any effect on a non-primary contract," typically occurs in the context of payroll processing within the SAP Human Capital Management (HCM) module. This warning indicates that the wage type MENI (which is often used for specific payments or deductions) is being applied to a non-primary employment contract, and as such, it will not have any effect on the payroll calculation.
Cause: Non-Primary Contract: The employee has multiple contracts, and the contract in question is not marked as the primary contract. In SAP, only the primary contract is considered for certain wage types.
Configuration Issues: There may be configuration settings in the payroll schema or wage type settings that do not allow the wage type MENI to be processed for non-primary contracts. Incorrect Assignment: The wage type may have been incorrectly assigned to the non-primary contract, leading to this warning.
Solution: Check Contract Status: Verify
