Could not connect to backend system through portal via Web Dispatcher

Web dispatcher redirecting problem

Dear Experts,

I have implemented a scenario which comprised of customizing that is developed in Portal EP7. What customizing does is getting report from backend system (ERP 6.0)

According to the needs for reaching the portal from internet I configured the SAP Web Dispatcher in the environment as you may see its contents below.

The problem is when I run the customizing in portal system then it requires connecting to backend system (ECC 6.0) to get the data (report). But from this point on web browser comes to a blank page, could not view the data that is from backend system via portal. Because in the time when it tries to retrieve data in backend system, on the left bottom of the explorer the indicator shows internet address that system uses connecting to the backend system as local network address of the backend system which is not known in internet therefore I get blank page.

The question is how to configure the web dispatcher in a way that both portal and backend systems could be reachable from internet?

Contents of profile file of Web Dispatcher as;

SAPSYSTEMNAME = WDP

SAPGLOBALHOST = portald

SAPSYSTEM = 02

INSTANCE_NAME = W02

DIR_CT_RUN = $(DIR_EXE_ROOT)\$(OS_UNICODE)\NTAMD64

DIR_EXECUTABLE = $(DIR_CT_RUN)

Hi,

To resovle this you must have registered FQDN for your backend system as well. When you call the report from Portal using internet it should call that FQDN of your backend system then DNS will resolve this & you will get the expected page. This way only you can resolve this issue.

Thanks,
