PCID not valid: The received PCID for a new session duplicated the PCID assigned to another session, or the received PCID intended as an identifier for an existing session could not be associated with such an existing session, or an error was detected in the format of the received PCID.
VTAM® hint: PCID stands for procedure correlation identifier.
VTAM Information: When VTAM receives this sense code for a session initiation, it continues searching through the adjacent SSCP table until the destination LU is found or routing is exhausted.
VTAM hint: This error can occur during an attempt to take over a switched connection because a connection-network-capable control point (CP) on the connection network does not have a complete system definition. See the information about common APPN problems in z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for more information about this session takeover problem.
