How can I correct a typo in a callsign?

After the activation of OE/VB-507 I entered my QSO’s into the database, and now I was told that one of the callsigns I entered is not correct. The OM who found the mistake is correct, I made a typo and I have copied his callsign correct in the Qso, but it is not correct in the database. Now I would like to correct this mistake, but found no way to do it. Can anybody help?

I think SOTAwatch needs a FAQ !!

This question comes up quite regularly, you should find the answer already somewhere in the reflector.

Here is one:
