Explanation
CPI Communications detected an invalid LL field in the GDS records from which it was receiving on a mapped conversation.
Although it is possible that the remote system is sending invalid records, it is more likely to be an error in the receive logic because DFHZARRC (a lower level receive module) also checks the LLs before passing them to CPI Communications.
System action
The transaction is abnormally terminated with a CICS transaction dump.
User response
Use CICS traces and, possibly a VTAM trace, to determine the data that was sent between both systems.
A level 2 CICS trace for 'CP' of the transaction documents the course of events prior to this error (such as the modules called and their parameters). The level 2 trace also provides details of the error itself.
