Logical port error when accessing e-recruiting web pages


We are trying to set up our e-recruiting 3.0 and web dispatcher systems. We were receiving an error in our e-recruiting system in transaction SM20 that states “Logon Failed (Reason=34, Type=H)”. The user is SAPSYS for client 000. The system was attempting to log on to our web dispatcher system. SAP suggested creating an entry in SM30, table VUSREXTID, mapping the External ID to our web dispatcher system. This entry helped in that we are not receiving the above error message anymore. However, when we attempt to access the web pages we are receiving the error “Name of logical port ‘&lp_name&’ is invalid. Prior to adding this entry we were able to access the logon page by entering the following url using an external alias (ex. is our web dispatcher system. We do not want our e-recruiting system to be accessible from the outside. We want everything to go through our web dispatcher. Has anyone had a similar issue setting these up?

    Hello Heather,

    I am no specialist in network infrastructure but i remember a customer setting up a web dispüatcher szenario. I also encountered this &lp_name& error from time to time during my work.

    The error points towards damaged urls and the customer also encountered such problems when setting up the web dispatcher landscape. Sometimes the last parameter of the URL was ignored or lost. Sometimes the web dispatcher transformed the URL including the parameters. But as parameters are case sensitive transforming them to upper/lower result in errors as the system no longer recognizes them.

    Perhaps you can check the URL with which the web dispatcher is calling the sap server to find out if it does any funny things w/ the links.

    Best Regards
