Hello all,

we’re implementing Learning module for an FSI client.
We’re using alert composer to create and send alert for recently withdrawn assignments, we’re using WLF-00011.
Running the alert (scheduled 1 times for day), the system sent email also for withdrawn made in the past (i.e. some months ago). We tested alert into DEV1 environment, and it worked correctly. Checking the WLF-00011’s expression, the alert should had be send an email just for withdrawn made today or yesterday. Following, the expression:

TRUNC(${withdrawnDate}) >= ${AlertFilterUtils.addDays(AlertFilterUtils.getCurrentDate(),-1)}
