Function Module to get Work schedule

hello experts!

I am trying to find a function module or tables that will allow me to get the work schedule information for a particular Work Schedule similar to PT03 ALV view. If there is a function that reads this information that would be great. I just do not want to do this on a personnel record (pernr) basis. I can see the data within table T552A however I can't make sense of the data in fields TPR## to align that with dates/weekdays or other tables.

Can anyone help me figure out if it is possible to either read the work schedules using a function or directly from one or many database tables?

My desired outcome would be to get the PT03 ALV display output using a function or database tables which includes the date, day (mon/tues/etc), daily work schedule, day type, holiday class.

Thank you,

Mike
