New Functions in the iPPE Process Structure

Use

Within Integrated Product and Process Engineering (iPPE), you can use the process structure to create your routing data in the system. In Release DI 4.6C2, you can use the process structure to fully reproduce your production and assembly processes on takt-based production lines. As of this Release, the process structure can be linked to product cost controlling. This enables you to make complete cost estimates for products for which you maintain production master data in iPPE.

The following new functions and enhancements are available for the process structure as of Release DI 4.6C2:

  • Improvement of multi-level structuring and multiple use of substructures.
  • Introduction of the activity type to differentiate between assembly activities and setup activites in the header data of the activities.
  • New detail screens for maintaining modes.
  • Clear application lists for assigning components and line elements quickly.

These developments are described in detail below:

Improvement of multi-level structuring and use of substructures.

Previously, you could create sequences between activities to define the order of individual activities only. This restricted the multiple use of structures below a grouping activity or below an operation. In the new Release you can also specify the order of grouping activities and operations. This means you can use this node type for representing multi-level structures, and also for multiple use similar to standard routings.

The following rules apply when you set sequence relationships:

  • Within one hierarchy level in a process structure you can maintain a sequence between nodes of the same type only. This means you cannot maintain a sequence between an activity and an operation.
  • The nodes must be assigned to the same higher-level node. For example, you can maintain a sequence only for activities that are assigned to the same grouping activity.

The following functions and evaluations support you when you are maintaining sequences:

  • Predecessor-Successor Maintenance tab page
You can maintain a predecessor or successor for each element in a process structure that is assigned to a higher-level object. The predecessor/successor must be assigned to the same higher-level object.
  • Sequences of Subordinate Objects tab page
On this tab page you can specify the sequence of all assigned objects in one step. For example, for grouping activities you can specify the sequence of all the assigned activities. This sequence is automatically transferred into all the process structures in which the grouping activity is used.
  • Overview of Relationships tab page
On the Overview of Relationships tab page you can call up the Hierarchy Overview and Activity Sequence evaluations. These overviews are particularly interesting for routing plan headers or grouping activities on the highest hierarchy level. For multi-level structures, you are shown the sequence of individual objects on each hierarchy level. The activity sequence shows the sequence of all assigned activities. For example, if you call up the activity sequence for a routing plan header, the system explodes the complete process structure and calculates the order of all the activities that are usually on the lowest hierarchy level.

New detail screens for maintaining modes

Several detail screens are offered for maintaining modes:

  • Mode tab page
This detail screen contains the most important mode data, such as plant, primary resource, duration, standard value determination type, time analysis data.
The Fixed and Variable Duration fields no longer exist. They have been replaced with the Duration field. The system interprets this field as a fixed or variable duration depending on the activity type.
You can create a production resource directly from the primary resource field and assign it to the mode. At the same time, you can specify whether the production resource is of type worker or of type operating facility. If you wish to carry out capacity requirements planning in the APO for employees, you must use the type 'worker'. If you wish to plan the use of operating facilities, you must use the type 'operating facilities'. The primary resource also establishes a link to the cost center and activity type, which form the basis for product cost controlling.
  • Secondary Resources tab page
On this detail screen you can assign more capacity requirements in the form of production resources to the mode, such as important production resources and tools.
  • Costing Data tab page
On this detail screen you can assign costing data that you have already created for production activities, or create new data, such as cost element, costs for a unit of measure, and so on.
  • Line Assignment tab page
On this tab you assign a line element to the mode, which shows where this mode is to be carried out. This enables you, at an early stage, to determine a relationship between the mode of an activity and the place it is to be carried out, without having to create a line balance.

Application Lists

With the Product-Process Assignment list, you can check whether the component variants (components), which you have created in the product structure, have already been assigned to the corresponding activities. You can assign nodes and variants, which have not yet been assigned, to the relevant activities using drag & drop.

With the Line Assignment list, you can check whether you have already assigned the mode of an activity to line elements in a line structure. You can also use this list to assign a line, by loading the process structure into the navigation area and assigning the line segment to the relevant mode using drag & drop.

Effects on Existing Data

Since the Fixed and Variable Duration fields no longer exist for the mode and have been replaced with the Duration field, you must take note of the following if you have already maintained activities in the previous Release:

  • Activities for which you have maintained a variable duration are converted into activities of Activity Type Assembly. The variable duration is transferred to the Duration field and handled by the system as such.
  • Activities for which you have maintained a fixed duration in the mode are converted into activities of Activity Type Setup. The fixed duration is transferred to the Duration field and handled by the system as such.
  • If you have maintained both a fixed and variable duration in a mode, the activity is converted into an assembly activity and only the variable duration is transferred. The fixed duration remains available in the the database only. It is not displayed, nor is it used for planning.

Effects on Data Transfer

Effects on System Administration

Effects on Customizing

The IMG activity Define Standard Value Determination Type has been added to iPPE Customizing.
