After running the Verify utility, the Qbwin.log displays the following error:
Error: Verify Target: Invalid Class. Rcrd = (######). Ref = (####) - A target contains a pointer to a non-existent class.
A class record used on a transaction or time activity is damaged.
When class records become damaged, adding new classes will assign the new class to the record number of the damaged or missing class. The number of class records to add depends on the number of classes that remain on the list and the record numbers associated with the damaged class.
For example, if the ref # is 25 and there are 10 classes currently in the list, add at least 16 more classes.
