Deleting relations in the process hierarchy

This method describes how to delete existing relations in the process hierarchy (including fastenings) to products and resources. In a complex process hierarchy,  that may contain 100 or 1000 processes (activities), this method allows to delete all existing relations in one go, without having to select the relations individually.

This method offers three basic procedures:

  1. Delete all relations between processes and resources.
  2. Delete all relations between processes and products.
  3. Delete all relations between processes and resources and products.

Schematic representation of the function

The following schematic representation introduces the principle procedure for deletion of existing relations from the process hierarchy.

 

Relations to resources and products in the process hierarchy

Initial situation: All existing relations between process activities (Act..) and products (Prod...) and resources (Res...) are displayed.

Deletion of all relations to products

The figure schematically shows all remaining relations between process activities and resources (Res...) after performance of the procedure -  Delete all relations to products.

 

Deletion of all relations to resources

The figure schematically shows all remaining links between process activities and products (Prod...) after performance of the procedure -  Delete all relations to resources.

Delete all relations to resources and products

The figure illustrates schematically that all existing relations are deleted after the procedure - Delete all relations to resources and products - has been performed.

Limitations for simulation applications

By means of relations, resources are linked to processes or process activities in the process hierarchy. Resources, such as robots or workers with assigned structures containing processes for simulation, need to be treated differently when relations are deleted.

Observe the following limitations for deletion of relations:

  • Relations between simulation processes and the resources are not deleted if you have selected a process or process activity in the process hierarchy.
  • Relations between simulation processes and the resource are deleted if you have selected the activity in the resource structure to which the simulation processes have been assigned.
  • Selection of activity in the resource structure (Task).

 

 

  • Simulation processes (SimAct..) are deleted.

Deleting relations

In the process hierarchy, relations may exist between process activities, resources and products. The following description outlines the procedure for call up of the DPM dialog, selection of an option and deletion of existing relations.

To delete relations, select a process or process activity in the process hierarchy.

  1. To open the dialog Delete Assignments, in the process hierarchy select a process or an activity. In the example a Process has been selected.

  2. After selecting, click the icon   in the Activity Management toolbar.

  3. Select the desired option in the Delete Assignment dialog. In the example the option Delete all product and resource assignments has been selected.

  4. Confirm the selection with OK. In the example all relations between the selected process hierarchy and resources and products are deleted.
