In job log, we could find a trace like this:

===================== SUBMISSION ERROR =====================

BAPI error number :
      id   :
      message :
============================================================

Relaunching them allows to submit them correctly.

Environment

Release : 6.x

Component : Manager for SAP

Cause

Defect: due to an error within the libnwrfc that seems to take a few seconds to correctly load.
To avoid this behaviour, a small retry mechanism, based on UXSAP_NB_CONNECT_RETRY variable is taken into account.

Resolution

Workaround:

Relaunch the aborted Jobs or delay its startup before starting the Node or Manager for SAP.

Solution:

Update to a fix version listed below or a newer version if available.

Fix version(s):
