IDOC and QRFC options in EM

[former_member193027]

Hi,

We are working on a design aspect where EM is integrated with ECC and TM. i HAVE THE FOLLOWING QUESTIONS:

a) For ECC-EM and TM-EM integration what are the pros and cons of using idoc and qrfc approach.which is the preferred method?

b) secondly is it preferred to have EM server inbuilt within TM and ECC or separate server for both

Hi Dipak,

As per my opinion:

1. QRFC is preferred method when you integrate SAP ECC and SAP TM with SAP EM.  Just check this table as IDOC will not fetch event handler data.  The advantage of using IDOC you can trigger exception handling.  However, qRFC is missing this factor but you can implement CCMS monitoring for queue failures, stuck, Running status for long etc.

Description	IDoc Type	RFC	BAPI
Sending event messages	EVMSTA02	/SAPTRX/BAPI_EHADDEVENTMSG_02	EventHandler.AddEventMessages02
Fetching event handler data	No IDoc available	/SAPTRX/BAPI_EH_GET_DATA	EventHandler.GetData
Creating or updating event handlers	EHPOST01	/SAPTRX/BAPI_EH_POST	EventHandler.PostEventHandler

Source: SAP

2. There was a discussion on this and Stefan confirmed that we can have SAP EM on SAP TM SAP Netweaver box.  However, prefer to have it as separate server (due to volume of events processing) or at least separate client on SAP TM.  This rule also applies to SAP ECC but if you are using both SAP ECC and SAP TM then preferable would be on SAP TM box.  Also check this article SAP Event Management - Six Key Things To Consider During Server Sizing.

Also, you can wait for other members comment, they can also give you some insights on this.

Hi,

When ever we are using QRFC does it mean that communication is stil there between SAP TM and SAP EM via PI?

[former_member186607 · Accepted solution]

When you use QRFC the communication is done directly between the two systems (EM and TM) without any system in the middle (PI).

Thx for the clarification. So in that case if we are not using PI but rather using QRFC approach do w e also check thru SMQ1 and SMQ2 for monitoring? In case any message exchange fails how can we track since without involving PI, SXI moni will also not work in that case.

Hi Dipak,

Yes, qRFC is a right approach.

SMQ1 and SMQ2 Monitoring - You can talk to Basis team to configure CCMS, so when queue fails it sends an email to support to look at it.

Hi,

Do we use Qrfc approach also when connecting EM with ECC or is it better to route thru PI?

Hi Dipak,

EM to ECC does not need PI. Qrfc can be used.

Thanks,
