         This section specifies the template ref_work_order.
         
      
      
         NOTE 
         The template has been defined in the context of 
         MoDAvDEX.
         Refer to the business context for details of related templates.
         
      
      
         NOTE 
         An explanation of a template and the associated instantiation path is
         provided in the 
         Template overview
         section.
         
      
      
      
               
         This template describes how to represent a reference to a work order.
             
       
      
      
         The EXPRESS-G diagram in
         Figure 
1
         shows the templates and EXPRESS entities that are required
         to represent the template 
         "ref_work_order".
         The text highlighted in blue shows the template parameters.

         The graphic for the template to be used in other EXPRESS-G diagrams
         is shown in Figure

Figure 2 —  The graphical representation of the ref_work_order template
      
         The following input parameters are defined for this template:
         
      
      
      
      
      
         The following reference parameters are defined for this template:
         
      
      
      
         
            Allow the 
            
Work_order
            entity instantiated in this path to be referenced when this template is used. 
            
         
 
         
            Note: The 
            
Work_order
            entity can be referenced in a template path by:
            
         
 
         %^target = $ref_work_order.work_order%
         
            where 
            
target 
            is the parameter to which the 
            
Work_order
            is bound.
            
         
 
       
      
      
      
         
            Allow the 
            
Directed_activity
            entity instantiated in this path to be referenced when this template is used. 
            
         
 
         
         %^target = $ref_work_order.dir_act%
         
       
      
      
      
         The following parameter combinations specify a uniqueness constraint:
         
      
      Unique constraint: Unique work order
            Each instance of the   
            
            entity
            
            (
Work_order)
            within the data set shall be uniquely identified 
            
            
            by the following parameters on this
            template (ref_work_order) namely: 
            
wo_id.
The 
            
            instance is
            
            referenced by the following template parameter:
            
work_order.
            
         
 
       
      
      
         The instantiation path shown below specifies the entities that are to be
         instantiated by the template.
         
      
      
         A description of templates and the syntax for the instantiation path is
         provided in the 
         
         
         
            Templates  Help/Information section.

Characterizations
      
         No common characterizations of the template 
         ref_work_order
         have been identified. However, the ISO 10303-239 EXPRESS model
         may enable other assignments to the entities instantiated by the template.
