You use this function when want the system to automatically generate an object management record when an object (such as a BOM) is being processed.

You do not want changes to be valid on the date in the change master record header, but on an alternative date in the change master record.

This function is available for the following change objects:

• BOMs
• Routings
• Documents
• Materials

In Engineering Change Management Customizing you have set the Assign alternative date indicator in Setup control data.

You have set the MgtRec indicator for the object type you are processing, in the change master record.

Apart from this you have also created one or more alternative dates in the change master record.

When you process an object using a change master record, which already contains one or more alternative dates, the system automatically displays a dialog box on the object maintenance initial screen (such as, for creating a BOM), where you can directly assign the object to an alternative date.
