does anyone else have issues with trying to find the difference between two dates in the system notes? The formula i have written doesnt have any errors but im not getting any results here is the formula (CASE WHEN {systemnotes.newvalue} LIKE 'QC Received' THEN {systemnotes.date} end)-(CASE WHEN {systemnotes.field} LIKE 'Document status' AND {systemnotes.oldvalue} LIKE 'Pending Refund' THEN {systemnotes.date} end)
