The Last Processed Date work in conjunction with the Next Payment Date to do catch up payments.

This process is assuming that the workflow "Last Processed Date Check for Monthly" related to the "Recurring Payment" object is not active.  If you do not want catch up to occur, then please enable this workflow.  If this workflow does not exist in your instance of Salesforce then please upgrade to the latest release.

For example:

If the following values were setup:

• Today's date is the 25/07/2016 (July 25th, 2016)
• Payment Day is set as "01"
• Last Processed Date is set as 1/04/2016 (April 1st, 2016)
• Next Payment date is set as 1/05/2016 (May 1st, 2016)
• Frequency is set as Monthly
• Amount is set as $50
