I am also curious why the removal of those security updates had anything to do with this. Its obvious to me that you are accessing Lawson tables. since EZACDT is a number value, I suspect you either have null values or some weird number that doesn't convert to a date. I don't know if you know that the source of CINACC is from table MITTRA. I have seen some odd Transaction dates in MITTRA (which become the EZACDT date in CINACC) These dates are at times manually entered with no validation and users fat finger them. You also seem to be using a View of CINACC, is there some sort of logic or conversion going on in the view?
