No connection to ESR. Only local data are displayed.
Message no. ES_BROWSER006

Cannot determine Repository Version

Requested Repository is down

Diagnosis

The connection to the Enterprise Service Repository is not functioning. The system can only display information for proxies that already exist in the local system.

You cannot create or re-generate proxies for ESR objects under these conditions, because the system needs to be able to read an interface description from the Enterprise Service Repository.

Solution

Check List for Setting Up a Connection to the Service Repository

The address of the Enterprise Services Repository must be known in the SAP system. Check with report SPROX_CHECK_IFR_ADDRESS.
In order to connect to an ESR, you have to maintain the RFC destination “SAP_PROXY_ESR“. This RFC destination will then be used by proxy generation / Transaction SPROXY. It has to be set up using transaction SM59 and should look like this:

RFC Destination: SAP_PROXY_ESR
Connection Type: G (HTTP Connection to External Serv)
Description1: ESR for Proxy Generation
Target Host: esr_host
Service No: 1080
Path Prefix: /rep

Logon and Security:
Basic Authentication: active
User: esr_user
Password: esr_password

The HTTP Framework of the Web Application Server must function properly. Check with report SPROX_CHECK_HTTP_COMMUNICATION. Please be aware of the fact, that the HTTP framework is depending on the application server. Thus the result of the report may differ for different application servers.
Proxy generation must interpret the data of the Enterprise Services Repository correctly. Check with report SPROX_CHECK_IFR_RESPONSE.
