External information string

The external information string, or EIS, is the evfields field of the eventin record. This field carries the specific data of the change or task into the ITSMA Service Management system. These fields are placed in a single string with a user-specified separation character (the default is the ^ character). The first four fields contain specific functions that determine which change/task is being processed and what action the system should take. These fields are passed in a specific order.

Sequence	Field Description
1	Change/Task number of the object to be acted upon. This field is blank when opening a change or task.
2	The foreign ID. This field is the identifier of the change or task used by the external system. This field is used if a different number is used outside of ITSMA Service Management.
3	Action Token indicates which logical action to take, either: open, update, close, reopen, approve, unapprove, disapprove.
4	The Change Group or operator performing an approval action. It is only used for approve, unapprove, or disapprove.

The data fields in the EIS contain field-level data that Event Services uses to populate the change or task record being processed. If the action performed is not an open, these fields write over any existing data in the change or task. If a field in the EIS is blank, the existing data in the change or task is used. The exact field that each piece of data corresponds to can be determined by examining the proper input event map for changes (cm3r) or tasks (cm3t).
