Learn alert - assignment for specific course

Summary:

Custom alert with resource learnerLearningRecords

We want to to send the alert just for specific courses, so we tried to add the following filter:

${learningitemnumber}='OLC1894259'

However when this filter is added it does not run - we get an error

Other filters added:

TRUNC(${assignedDate}) >= TRUNC(sysdate)-3

${assignmentSubStatus} = 'ORA_ASSN_REC_NO_OFFR'
