Receiver categ. &1 is not allowed by settlement prof. &2 for this sender

What causes this issue?

The settlement profile specifies which receiver categories you can
settle a sender to. Receiver category &V1& is not allowed by settlement
profile &V2& for this sender.

How to fix this error?

You can do the following:
Assign a settlement profile to the sender, that implements the required
receiver category &V1&.
Choose "Goto -> Settlement Parameters".
Specify another receiver for distribution rule &V3&. If you already
used this rule for a previous settlement, enter a valid-to period. Then
enter a new rule for the next settlement with a receiver category. This
category must be one that is allowed by settlement profile &V2&.

Procedure for System Administrators

If necessary, maintain a suitable settlement profile.
