Hi,

I’m trying to migrate our process using SAP adapter from wM 7.1.2 to 8.2, and I’m having some problems with it.

The SAP connection is ok, we’re able to call BAPI and send IDOC to SAP, but not able to receive any IDOC. The SAP Listener doesn’t start with the following error message :

[ART.115.3257] Adapter Runtime (Listener): Exceeded max retries. Shutting down listener LVSAPListener:SAPListener. Error: [SAP.104.9151] WmSAP Adapter: Error on initializing listener: Startup error

Do you have idea how to resolve it? I’ve searched on Empower, and I found nothing on it.

Thanks you,

Hi,

I have a similar problem with a twist:

We have a test IS that we have successfully connected to a SAP server with the SAP listener happily enabled, and I can disable and enable the listener with no problems. However, we are migrating the IS onto another physical server so we have installed the IS and configured the SAP connection and Listener exactly as it is configured on the old, working, server; the SAP connection enables OK but the listener wont enable and I get the following errors in the RFC trace logs:

Has anybody else come across this issue?

Please work with your BASIS folks and make sure they configured RFCdestination/programID correctly along with gateway service you are using…And also the unicode setting on SAP side.

If everything configured correctly on both sides…restart IS freshly:

Hi All,

I am facing an issue which is as follows and need help:
I have 2 connections to the same SAP application server but with different Client IDs. both of them are enable.

I also have 2 listeners , one connecting to those connections respectively. The Program ID in this case is also the same.

I am not able to enabel both listeners in parallel. Please let me know what can help solve this issue.
