No connection possible to BI master system SAP_BW

1424 Views

Hello

We are using the BEX query designer (BI 7 version). When we open a query in design mode and we then click on the Execute button, we encounter an error as follows:#

- internet explorer opens up

- we are prompted to enter a user id / password

- we then receive an error message

We get the same error if we try to run the query from RSRT. If we run the query within RSRT itself, it runs successfully. If we run the query through RSRT ABAP web, it is also successfull. We get the error above if we try to run the query using the JAVA Web option.

Your assistance in this regard will be highly appreciated.

Kind regards,

Razia

The error message is as follows:

Exception in BI runtime
