Ok, so I'm using a date field in my replacement variable. I initially set the value equal to a date at the beginning of my range (right before the range starts in the data). I include the date field in my SELECT, WHERE, and ORDER BY. In my WHERE I added another date to be the cap to try and troubleshoot the issue of not updating (... AND resolve_time < '2019-04-01'). When I run the job, it works. The proper data is imported into Domo, the replacement variable updates its value - life is good. I then remove the date cap from my WHERE clause, change it to APPEND and re-run the job. This should find the rows that exist with April dates. However, no rows are processed this time, and the replacement value doesn't change.
Any ideas on this? Anyone run into this issue and was successful in getting around it? I'm stumped.
