wdisp/permission_table is a SAP Parameter attribute which is used to control Text file describing the URI permission table (SAP Web Dispatcher) 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 .
In the same way as for SAProuter, you can maintain a table for SAP Web
Dispatcher that defines which URLs and protocols are accepted and which
are rejected. If there is no permission table for SAP Web Dispatcher
(default setting), every URL is forwarded.
The syntax is the same as for saprouttab:
P = permit, D = deny, S = secure (HTTPS only) # = Comment, followed by
the URL. Wildcards (*) are only permitted at the start or at the end. As
with SAProuter, the first-match principle applies, that is, if an entry
that matches the URL is found in the table, the system does not keep
searching in the table.
# SAP Web Dispatcher test permission table
D *.cgi # don't allow execution of CGI programs
