How Does the Search by Class Schedule, Group, and Instructor Work in BILLING?

In MartialWave, the search function in the BILLING section retrieves data linked to the student's contract. When searching by instructor, for example, the system will return contracts that include class schedules associated with the selected instructor. However, it's important to note that a single contract may contain multiple class schedules, disciplines, and instructors. The charge amount always reflects the total monthly fee of the contract, not individual components within it.
