Mandate checks failed for bank area &1 acct no. &2 certificate no. &3

What causes this issue?

You have fixed a fixed term agreement account with a latest term start
date and a fixed duration. As a result, the system has updated the
rollover terms with a new term start date and a new collection date. The
mandate checks have failed for the new term start date and the new
collection date.

System Response

The mandate entered in the account is not appropriate for the rollover
term agreement. This means that the next term is not processed correctly
during collection.

How to fix this error?

Check the mandate's validity in the rollover term agreements.
