Payroll Period on LDB PNPCE

Hello All,

Can anyone Please tell me the use of Payroll Period on PNPCE LDB Selection Screen

Lets say if i input

Payroll Area = P1

Payroll Period : 10 2012

Personnel Number 123

so my questions are

1) Does the LDB automatically checks whether the Personnel Number 123 is in that Pay Roll Period ...

Or does it get the information about the Personnel Number and i have to explicitly check whether that Personnel Number had a payroll for Period 10 2012

I mean to say that the Payroll Period behaves like Data Selection period Screen

The Values in the Data Selection Period on Selection Screen doesn't have any influence on Results returned by LDB ,as a programmer you have to use those values to filter out information

Thanks
