ESS/MSS publishing - ERROR_INTERNET_NAME_NOT_RESOLVED

[Former Member]

Hi,

We are configuring ESS/MSS external facing with Web Dispatcher 7.20. We have got public URL, signed certificates, ports opened on both internal and external firewall.

Authentication of users is happening successfully, screens and iviews from EP system are also pulled successfully without any issue.

Both EP (7.31) and ERP (ehp5) are individually added to Web dispatcher and we are able to individually call and login into ERP  and EP systems via public url.

External System object in EP system have WD details inp-lace of ERP system details. Table entry for HTTPURLLOC table is also maintained in the ERP system.

Issue is that when we try to pull data from ABAP webdynpros in ERP system from ESS/MSS iviews present in EP - public url is getting transformed into intranet url with ERP system's hostname and internal HTTP port.

Using HTTPWatch we found that “ERROR_INTERNET_NAME_NOT_RESOLVED” is occurring for all URLs like below ones,
http://FQDN:8000/sap/bc/webdynpro/sap/HRESS*
http://FQDN:8000/sap/bc/webdynpro/sap/HRMSS*

How can we avoid public url switch to intranet url. Are there any specific configuration required for ABAP webdynpros.

Regards,

Siva

Hi Siva,

You need to create NAT your local IP address of ERP system to the public IP so that ITS links can be opened correct over the internet.

Check with network team for more information on how it can be done.

Hi Deepak,

Thank you.

So is this how we publish BSP and ABAP weddynpro applications of ERP on internet ?

And what about web dispatcher that we have configured.
