Pennsylvania Taxes

Hello- we are a NY employer just adding a new enity located in Pennsylvania for the first time.  We use Lawson/BSI .  We have some questions regarding the tax authority set up  and assigning the PSD codes and in addition tracking the PSD for tax reporting. .  I see that we need to  set up the codes on PR06.1-PR69.1.

When checking BSI for a home address,  for example,  we see that we need withholding for Eldred Borough and also Otto-Eldred School District. Would we need to set up 2 tax authorities and assign each a PSD code and also a unique deduction code?? ?  Is it a one to one relationship??   The names in BSI are different than the PA state guide so I think that is adding to the confusion.  

This is all brand new and my head is spinning !

Is there anyone who would be willing to share any expertise to get this a little clearer?  It would be very appreciated !!!!
