These 2:
wdisp/system_0 = SID=EPP, MSHOST=EPPVS01.ENGPL.com, MSPORT=8100,
wdisp/system_0 = SID=EPP, MSHOST=EPPVS01, MSPORT=8100, SRCVHOST=EPPVS01.ENGPL.com
And these ones:
icm/server_port_0 = PROT=HTTPS,PORT=443$$
If you want port 443, you need to remove the $$
icm/server_port_1 = PROT=HTTP,HOST=SAPWDP01,PORT=81$$
icm/server_port_2 = PROT=HTTP,HOST=EPPVS01,PORT=81$$
icm/server_port_3 = PROT=HTTP,HOST=localhost,PORT=81$$
You can't have multiple services on the same port, because you are using 00 for the WD, all 3 ports will try to attach to port 8100
