ERB256I

Explanation
In the input data set, the RMF™ Postprocessor found spanned records without
their spanning indicators. The Postprocessor issues this attention
message because such records may be truncated or incomplete. ccc indicates
the column in the report affected by the apparently truncated records.
During
a session, RMF can generate system
management facility (SMF) records that are so long that the records
are spanned, that is, occupy more than one physical block. Spanned
records are most likely when RMF is
measuring I/O activity for direct access devices. The spanning indicators
can be lost through improper copying of the SMF records.

System action
The Postprocessor continues to generate the summary
report using the data available and eliminating no columns.

System programmer response
  Review your installation's procedures
for copying or processing the SMF records produced by RMF. In particular, make sure that the IFASMFDP
program is used to copy records from the SMF data sets. See the z/OS MVS System Management Facilities (SMF) for
further information.
