We import new employees. One of the states is Pennsylvania, which has a local tax code for schools, or PSD. PSDs are roughly based on the city and zip. Before I import an employee, I want to compare the employee's city, zip, and the PSD code they provided during the onboarding process to a table of PSD codes (about 2,300 of them). I then want to check if the cross referenced PSD code has been setup in the Tax Table file **by looking at existing local codes in Sage**. If it hasn't, I block the employee from importing and notify the user in an error report, which PSD needs to be added to the Tax Table file. We can't load all the PSD codes, because we only have 3 chars to use for the Local, so we load new ones as needed.
