Change Master Records 

Change Master Records contain data that both defines and controls a change. Other data also provides you with information on changes made to the change master record.

This data is maintained on a number of screens. The main data is included on the following screens:

On this screen, you enter the change number to identify the change master record.

The change header includes fields that define the change (such as the valid-from date), fields that describe the change (such as the reason for change), and some administrative data.

Object types let you determine which objects can be changed using the change master record. If you want to process BOMs with the change master record, you must specify various object type indicators for object type Bill of material.

Object sub-types let you determine more precisely how you want to process different types of BOM (such as material BOMs and document structures).

The general valid-from date in the change header can be replaced by a different valid-from date for a specific change made to an object. To do this, enter an alternative date and then assign one or more change objects to it.

The object management record allows you to control changes to a specific object.

This screen allows you to define the exact change to be made to a specific object. You can also use the selected change number to lock the object to prevent changes.

If you make a change with an engineering change request (change master record with a change type), you can use the system status and, if necessary, the user status to determine how the change master record is processed.

If you use an effectivity type (such as effectivity by serial number) in the change master record to define the effectivity of a change, enter the values for the effectivity type (for example, a range of serial numbers).
