Within R/3 Engineering Change Management, you can define specific effectivity types for making changes to the product. This allows you to adapt your range of products quickly and easily to respond to any changes in the market, for example, by reacting to the season by changing the color for a certain time period or a certain customer. The relevant functions are combined in Customizing for Engineering Change Management in Logisitics-General under Parameter effectivity and are activated at client level.
The parameters that you can freely define (for example, material, date, customer, serial numbers) are assigned to an effectivity type (such as a serial number or time range). You can assign several parameters to one effectivity type (also known as validity type), such as customer and date, which allows you to make changes to a product for one particular customer for a certain time period.
In the standard system, you can set the effectivity types for time and serial number ranges in Customizing for Engineering Change Management. You can also define additional effectivity types with freely-defined parameters.
To define the effectivity type parameters, you can:
As of Release 4.5A you can also assign values to sales document items
(such as bills of materials) in sales document processing with parameter effectivity types.
The system forwards this assignment to requirements planning, configuration, assembly and costing.
Materials that have been assigned effectivity parameters are displayed in a dialog box in the sales document. The values are also included in the incompletion log.
You must configure teh following settings so that the parameter effectivity for an item in the sales document takes effect:
To make your own specific enhancements, you can use the function exit EXIT_SAPFV45S_005 in the V45S0004 extension.
The system does not consider parameter effectivity in the sales documents for exploding bills of material (without configuration). The system does not call up the paramater effectivity automatically if changes arise that are relevant to the effectivity.
You can find more information in the release note Extensions for Parameter Effectivity and in the R/3 Library documentation for LO - Engineering Change Management.
