AS = EM, still need a qRFC ?

[Former Member]

Hello all,

I understand the need of synchronous vs asynchronous connection. but I don't understand the following:

Irrespective of whether SAP Event Management and the application system run on the same system or not, you must use qRFCs for the integration. Do not set Local. If you want to test the communication or debug, set Sync.

Why ?

Thanks,

Deb

If you use "local" flag technically a normal Call Function is done. This won't work in most of the scenarios. It is only there for downward compatibility as it was used at the beginning of EM vor very simple scenarios.

Hi Deb,

Most of the systems are designed to have "Asynchronous" in Production system.

Why?

1. Compare to Dev and QA, the production system sends huge amount of data to SAP EM system.  If the source system sends with attachment then it would have a major impact in "Synchronous" because each even handler and even message data few KB's.  Then multiply times to 1000 or more then the server would not have capable to handle in short amount of time all data. Sometimes, server would hang due to large amount of data at specific time, if it is "Synchronous" mode.  However, "Asynchronous" mode on qRFC can process the queue one by one intelligently and send it to SAP EM without any issue.

2. Another important one - Server load impact if multiple source like 3 PL/4L sends data in Synchronous at specific time.

3. Number of users work on system - For example - Shipment team has 20 members and they come in the morning at 8.30 AM and all of them creates pending shipments at the same time.  The event handler and expected events will update at same time and create issue again.

These technical points needs to be addressed during server sizing questionnaire and followed on SAP EM system configuration.
