We are using the  "lock return" feature.  Return is prepared, reviewed, printed and locked.  When we e-file that locked return, it is rejected.  Every time.  Every type of return.  We have to unlock the return, rerun the review, save and lock it.  Then it can be efiled.  HOWEVER, as soon as we unlock it, we expose the data file to potential changes by the ProSeries program changes.  Are we doing something wrong or is ProSeries not doing something right?
