System-Aided Resource Selection
Use
If several resources can be used as the primary resource of an operation, you often cannot decide which resource you will actually use until shortly before production.
This function helps you make this decision as the system preselects suitable resources in the process order.
You maintain the criteria the system uses for this selection in the resource and master recipe. When you release an order, the system also uses these criteria to check whether you may use a resource.
Prerequisites
You have installed the application component
Classification System
(
CA-CL)
.
Classes for alternative resources you can use have been created there. These classes meet the following requirements:
They belong to class type
019 work center class
.The class characteristics describe the resource characteristics that are relevant to selection.
Caution
The master recipe only supports the date validity of engineering change management (see Engineering Change Management and Recipe Approval ). For this reason, do not use classes or characteristic with parameter effectivity.
If you want to use system-aided resource selection for operations, assign a planning resource to these operations in the master recipe (see Assigning Primary Resources to Operations ).
Features
When selecting resources, the system takes the following criteria into account:
Whether the resource is contained in the resource network of the order
You define the resource network during recipe editing in the recipe header (see Resource Network Assignment to Recipes ).
User-defined resource characteristics
You define them in the resource and in the operation of the recipe using the classification system (see below).
Resource selection using the classification system
For resource selection, you can use your own classes of class type
019
work center class
. Using these classes, you specify the following in the master data:
Resource:
You assign similar resources to the same class. You assign the individual resource attributes to the class characteristics.
Example
You have defined the class
charging vessel
along with the class characteristics
volume
and
stirring speed.
You assign the resource master records of all available charging vessels to this class. In doing so, you enter the volume and stirring speed for each resource.
Master recipe:
You enter resource selection conditions for the operations of your master recipes. In these conditions, you:
Assign the operations to the same class as the resources that are used to carry out the operations
Assign the resource attributes that the primary resource of the operation must have to the class characteristics
Example
A mixture is to be created in operation 0010 of your master recipe. You enter a resource selection condition for this operation. In this condition, you assign the class
charging vessel
to the operation and determine the vessel volume required for the charge mixture as well as the stirring speed.
When you start resource selection in the process order , the system determines the resources that meet all operation requirements (see graphic below). Only these resources can be used when an order is released.
