I know how you can use the memo/department fields to enable the 'pencil' and mass delete records on a single-type saved search... Anyone figure out how to mass delete deposit applications? Much appreciated

In search criteria make sure put a filter as main line TRUE and other required filters that will give you the list of Deposit applications you are looking to delete. In results add a custom field which would be available on Deposit application transaction and then enable inline editing in results and you can click on pencil icon to delete those transactions via SS @Amar Patel

ok, i will add a custom field to the DA form and try that

Yup! Standard fields do not support that

@Abrar Shaikh i added a custom free form text field - still gives me error that record type is not supported

Yeah sorry, I think I mixed Deposit with Deposit application. Inline editing is not supported for Deposit application at the moment @Amar Patel

Yup, just manually deleted about 200.
