Adding any condition under pause on SLA definition form, it throws a message "First select a table" and doesn't allow to add the filter condition
The form hasn't loaded completely.
Sometimes a form takes a few more seconds than expected to load all the data it needs and if you try to add a filter condition under start/pause/stop, it throws a message saying "First select a table", even though the table is already selected. Let the form load properly and then try to add the condition.
After flushing out the cache the issue is resolved
