WmSAP Adapter: Missing notification

, ,
1

Hello,

I’m having this odd behaviour with a SAP Notification:
A SAP test package calls the same SAP function (wich calls the IS Notification) twice, the first time it runs with no problems, in the second time it gives the following error:

Error in inbound call for Z_GP_SVC_OUTBOUND from ZAVSAP: [SAP.111.9506] WmSAP Adapter: Missing notification - MsgType: Z_GP_SVC_OUTBOUND (D01100 >> WM_CONNECTION_TEST).

When we first had this, was just after creating the Notification, and in the middle of trying to solve the issue we finnaly restarted the IS and afterwards it disapeared…

Anyone can give me a hint in why this is happening? And how can I solve it?

We found the error.

The problem was with the listeners configuration.
We have two different listeners, both configured with the same “Program ID”.
Once we disabled one of the listeners, the error disappeared.

This might be common knowledge for SAP users, but a small note in the SAP Adapter documentation in the Listeners chapter would be a nice update for those not so familiar with it.
