Engineering Change Management: Effectivity (Validity) Types for Bills of Material
Description
Previously, you could define the effectivity of an object change using the valid-from
date of a change number. The change becomes valid on the valid-from date.
As of Release 4.0A, you can use new effectivity types to define the effectivity of changes to BOMs.
Standard R/3 System
The following new effectivity types are defined in the standard R/3 System:
You can define the upper and lower limit of the effectivity period of an assembly.
- Serial number (range of serial numbers)
You can define the effectivity of an assembly in terms of the serial number of a finished product.
This is especially useful if the change to a finished product is subject to strict access restrictions.
You can use the Serial number effectivity type to define the effectivity of a change as follows:
- Valid for one serial number of a product
- Valid for a range of serial numbers for a product
Company-specific effectivity types
In Customizing, you can define company-specific effectivity types.
- You define parameters that are linked to a data element.
- This link defines the properties of parameter values (for example, alphanumeric string of 18 characters).
- The parameter type that you link determines the possible entries in the
field (for example, a single value or an open interval).
- You assign the parameters you define to an effectivity type, and enter
the priority of the effectivity type for changes to objects.
Change system parameters in customizing
Before you can use the new effectivity types to define the effectivity
of changes to BOMs, you must define the following settings in Customizing:
In this step, you activate the new effectivity types.
Further notes
The new effectivity types are only supported for BOMs in this release.
Once you have defined a change master record with a new effectivity type, you can only use it to change BOMs.
