Forum Post: RE: "The current file's data dictionary definitions do not match those of the new file."

This is a very old thread but we ran into identical error on ERP2014: for unknown reasons data dictionary was damaged or mismatched on a dozen random tables. Solution was to restore providex.* files from backup, along with DDICTS folder (not ###.###). THEN add/edit UDF in each affected table to force update of data dictionary for that table. So far no data loss/corruption discovered... we'll keep our fingers crossed.
