Record type 73 is written when channel path activity measurement is requested. Entries are created for all 256 theoretical possible channel paths in the system.
Macro to Symbolically Address Record Type 73: The SMF record mapping macro for all records produced by RMF is ERBSMFR. Its format is ERBSMFR (n1,n2,...) where n1, n2, ... are the SMF record types you want to map. Note that the parentheses are required only when two or more record types are specified. The mapping macro resides in SYS1.MACLIB.
