This dashboard report outputs a percentage breakdown of the number of contacts that have donated to your organisation in the past in the LYBUNT and SYBUNT format, with the ability to filter by Source Code. In this case LYBUNT is Last Year But Unfortunately Not This year and SYBUNT is Some Year But Unfortunately Not This year, that is these contacts have donated in the past but have not done so in the current year.
The report will initially not have any output but you can set the source codes by selecting the parameter button at the top-right of the report window.
The output will contain information on the Donations including Amount, Sourcecode and the Contact's name/Address.
