IC Transfer number missing

SOLVED

IC Transfer number skipping a digit, for example after posting a transfer, TRF 0002, the next number generated is TRF 0004! (the image shows transfer no. TRF0005433 is missing

the user says that when he posted the system did not give him the option to print and the transfer "disappeared". So he has to re post the transfer.

We have disabled the SAVE and DELETE buttons for the user to ensure they do not delete any transfers.

I have run the IC integrity check and it shows zero error.

has anyone come across such a challenge? Please assist.
