Change-Header Data 
The change header contains both fields that define and describe the change and administrative data on the change master. The administrative data is updated by the system.
This data is maintained in the following data blocks:

¡ Function
This field is only displayed if you have activated the release procedure in Customizing.
The system displays the short text for the chosen function, for example Engineering change order with release key.
¡ Validity from orValidity date, or Effectivity
§ Valid-from dates
In the standard SAP system, commencement of effectivity is controlled by the Valid-from date. This is the date when the changes for all objects take effect. If certain requirements are met, the date can be shifted. For some change objects, you can replace this general valid-from date with an object-specific alternative date.
See also: Valid-From Dates
§ Effectivity
The function Effectivity is active when the change master record contains parameter effectivity.

¡ Rank

¡ Authorization group for the change master record

The authorization group is part of the Authorization group for the change master record authorization object.

¡ Reasons for change
You can enter a reason for change for all objects (for example BOMs).
You can add information about individual changes in the object management record. You can also maintain a long text for the object-specific description.
· Status information
· Status of a change number
This shows the actual processing status of the change number. The status determines whether objects (for example, BOMs, task lists) can be changed with reference to the change number and whether a date shift can take place.
You define the status in Customizing for Engineering Change Management, step Define status for change master record.
¡ Release key
This field is only active if you have chosen a function with a release procedure.
See also: Release Process Using the Release Key
¡ Deletion flags
Use this indicator to if you want the change master record to be deleted in the next archiving session.
You cannot enter any change objects or process any objects with reference to the change number when this indicator is set.
· Legal overlap period
This data is only relevant to the dangerous goods object type.
¡ Date when the legal regulation takes effect
¡ Date when the legal overlap period expires.
· Administrative data
This data is generated by the system. This data tells you when and by which user the change master record was created and last changed.
You can maintain further data in the change header after completing additional functions.
· Accompanying documents
If you want to enter detailed documentation on the reason for change, you can use the Document Management functions. To do this, you have to assign one or several document info records to the change header as accompanying documents.

· User status
This field will not be displayed until you have defined a status profile. Defining a status profile allows a change master record to run through a company-specific status network.
You define status profiles by choosing Change Type ®Define Status Profilesin Customizing for Engineering Change Management.
