Your customer pays their workers on a semi-monthly payroll frequency.

Comprehensive and Detailed in Depth Explanation:

To transition workers from a semi-monthly to a monthly payroll frequency in Oracle Payroll Cloud, the recommended approach is to create a new monthly payroll definition and transfer the workers to it. This maintains historical data integrity and aligns with payroll configuration best practices. Options A and B involve modifying the existing semi-monthly payroll, which is not feasible as it changes the payrollfrequency fundamentally and could disrupt past records. Option C, involving end-dating and creating new employment records, is overly complex and unnecessary, as payroll assignments can be updated directly. The "Transfer Payroll" process, detailed in Oracle documentation, supports moving workers between payrolls efficiently.
