rdisp/wp_max_no is a SAP Parameter attribute which is used to control Maximum number of startable work processes information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .

Parameter documentation
The parameter rdisp/wp_max_no defines the maximum number of work
processes that the server can start and therefore defines the size of
the internal process table.
During the start-up of the server, the work processes resulting from the
following parameters are started: rdisp/wp_no_dia
>, rdisp/wp_no_vb>
rdisp/wp_no_vb2>, rdisp/wp_no_enq>,
rdisp/wp_no_btc>, and
rdisp/wp_no_restricted>. The total of
the parameters must be smaller than or equal to the value of parameter
rdisp/wp_max_no.
If the operating mode is switched, the number of individual process
types can be changed. The criterion that the total must not exceed the
value of rdisp/max_wp_no still applies.
The "new" possibility of creating processes dynamically is also used for
handling deadlocks. If all the processes of a type, such as dialog, are
in the status "On Hold", a process with this type is restarted, if
possible. After the bottleneck has been resolved, the dynamic process is
stopped again. For more information, see the documentation for the
parameter rdisp/dynamic_wp_check.
To remain compatible with "old" configurations, you can assign the value
DEFAULT to the parameter. In this case, the value of the parameter is
the total of the above parameters plus 2.
