Triggered Instructions
Checking the triggered instruction history in 1E Core. The 1E Core application enables other 1E ServiceNow applications. For example, Tachyon instructions can be triggered from the incident form in the ITSM module of ServiceNow. 1E Core keeps a history of instructions it has executed (triggered) on behalf of those applications. The history includes:
The instructions
Parameters passed to a Tachyon instruction
Responses received from a Tachyon instruction
The Business Application that triggered the Tachyon instruction
Target end-user device.
Viewing Triggered Instruction History
A 1E Core administrator can view details for every instruction run in 1E Core on the 1E Core → Triggered Instructions page.
1E Core App roles required to view the Instruction History

Purging Triggered Instructions
The 1E Core application has common APIs that can be used by other 1E ServiceNow applications. Along with a group of other APIs, 1E Core has an API to purge instructions which accepts the following parameters:
Business Application Name
No. of Months.
The API purges triggered instructions specified by the Business Application Name and older than the given number of months. It will not purge triggered instructions passed by any other application and are newer than the specified number of months.
