Locking the Change Master Record After Release (SAP Library - Engineering Change Management (LO-ECH))

Locking the Change Master Record After Release

Use

You can release changes that you make with reference to a change number for specific enterprise areas by using a release key. You can lock a change master record that the changes have been released for against any other changes.

You can only process the following objects when you have set the lock:

Release key
Deletion flag

Prerequisites

You have set a release key for the change master record that releases the changes for at least one of the following areas:

Global release (all areas)
Release for costing
Release for planning
Release for production

You have set at least one of the Lock change number (using release key) indicators under Set up control data in Customizing for Engineering Change Management.

Procedure

In Customizing for Engineering Change Management, under Set up control data, set the Lock change number (using release key) for the area that the change master record should be locked for when you perform the release, for example, Release for costing.

Change the release key in the change master record.

If you set a release key with an indicator that causes the change master record to be locked, the system immediately locks all data against any other changes.

For example, if you set release key 04 (Release for costing), the change master record is locked on the basis of your settings in Customizing.

Result

You can only change the release key and the deletion flag. If you want to make any other changes to the change master record, you must first set a release key that does not support a lock.
