Part time employment percentage usage

Dear Team,

Does the employment percentage in planned working time infotype 0007 mean reduction working hours. If the hours are reduced, does the pay also reduces by such percentage.

For example.

100% employment an employee gets Rs. 1000.

If I change to employment percentage to 50%, does the employee gets Rs.500/-. How do we do this configuration.

Or any other behavior on this part-time employement.

Thanks and Regards

Team Member.
