Since the API calls to ActiveControl are asynchronous, the processing of statuses in the Domain Controller is done as part of a batch job running this program /BTI/TE_RU_SS_PROCESS.
It picks up all statuses in the status table /BTI/TE_SS_STATS and processes the entries per the configuration in /BTI/TE_SS_HANDL. The program is responsible for sending data back to smartShift if necessary.
A variant needs to be created for this program and then scheduled as a job via SM36. A typical variant will look like below screenshot.
