@JohnHoyt @MoiraGoggin - Yes, I agree. Users should be watchful in data entry. BUTTTTTTTT, ( a big but), this has happened to me in the past numerous times in numerous years. I coach my users to be alert on dates. I also coach my users to minimize their keys strokes. MMDD is my mantra. Let the system default the year for them. When posting to a prior month, change the module date to the prior month and enter all prior month invoices in that batch. Then change your date back. When I key dates (for the past 21 years) I use the FEATURE relentlessly. I have sent Diane Coffman emails for the past 4 years asking that this get fixed. She proposes it, her bosses dispose it as not important for the near future. Not a happy situation when it happens to you when you try VERY hard for the first two weeks being careful!
