Like the current TTU, there was some additional code in the 2008 Q1 TTU. It was to lengthen several fields in 3.71 when the FICA limit went to 6 digits. Rather than try that manually and miss something, I was hoping for this TTU which Phil kindly supplied. What has the client been doing the last few years? I don't know. The person that has been handling the books is in her mid seventies and will retire shortly. Version 2013 will be running very shortly after. Versions 4.2 and 4.4 have both been installed in the past but never used.
