There are times when we receive goods but cannot book them into stock as they may need checking to a drawing, for instance. Also the guys may not have the time or simply forget. I believe at the moment the only way to have a different date is to change the system date and then book them in against a GRN and then change the date again.
Most of the time this isn't an issue but can be a problem when receiving goods near the end of the month where they don't get inspected for a few days, which means they fall into next month fromĀ a GRN point of view!
