URL for task in SBWP

Hi

Need your help on identifying how the URL being generating when clicking the task / resource from SBWP.

We do have three server nodes and having web dispatcher.

SAPLOCALHOSTFULL profile parameter for each node having it's FQDN, ex : sapa.xyz.com / sapb.xyz.com / sapc.xyz.com

Now clicking on task generating like something like : https://sapa.xyz.com:8101/.........

Instead we need the URL to be generated using WD, like : https://sapdispatcher.xyz.com:443...

Could you please help on how can we achieve this.

Is that something like, we should maintain WD URL in SAPLOCALHOSTFULL for all three nodes and along with maintaining 443 for ICM.

How the HOST and PORT retrieved for constructing the URL ?

Please assist...

Thanks
