Standard SAP logging is possible as part of the Jenkins integration. The prerequisite for this is that the subobject of /BTI/TE is created via transaction SLG0 in the Domain Controller.
Note that INTEGRATION_NN, the NN should be the EXTSYST_NO as defined in /BTI/TE_INT_SYST.
Transaction SLG1 can be used within ActiveControl Domain Controller system to view the integration Logging output as part of the Outbound integration.
Nothing is logged in SLG1 as part of Inbound integration.
