Currently if generating reports using "Filters" at the "Prompt", it can't send the report to the recipients as the report generated "ignores/ doesn't recognise the filter" and the report size becomes high and undelivered.
To overcome this you need to build the filter within the report and NOT at the "Prompt" level.
The idea is to ensure the current "filter" at the "Prompt" to work thus giving freedom for PM's creating and quickly sending reports by exception.
