Yes, the PEP will reply with a RPT. The Report Type may be either Success or Fail depending on the PEP's ability to process the message.

Subject: Question about RPT
===============
The question is:
If the PDP received a malformed REQ Msg and reply a DEC as following:
<Decision Message> ::= <Common Header>
<Client Handle>
<Error>
Will the PEP reply a RPT Msg for such DEC?
If the report reply, then what's the report type should be?
Thanks

Here is an excerpt from COPS RFC 2748:
For every DEC message *containing a configuration context* that is
received by a PEP, the PEP MUST generate a corresponding Report State
message with the Solicited Message flag set describing its success or
failure in applying the configuration decision.
An excerpt from COPS-PR RFC 3084:
..... * As described below, the PEP MUST respond to each and every DEC with a
corresponding solicited RPT.
A COPS-PR DEC message MUST be treated as a single "transaction",
i.e., either all the decisions in a DEC message succeed or they all
fail. *If they fail, the PEP will rollback to its previous good
state, which is the last successful DEC transaction, if any. This
allows the PDP to delete some policies only if other policies can be
installed in their place.
