Defining Operations in Oracle Process Manufacturing (OPM)

Operations are composed of a sequence of activities and required resources. Enter and maintain the sequence of activities in the operation, and specify the resource, resource usage, and process quantity used for each activity.Resource usage and cost analysis codes associated with each activity are used to calculate activity-based product costing. 

Navigation: Process Engineer > Process Engineer

Process Operation Details Activities window. 

Enter the Operation name. Required. 

Enter the Version number for this operation. The combination of operation and version must be unique. Required. 

Enter a brief Description for the version entered. Required. 

Enter a Class for this operation to identify how it is categorized.

Navigation: Process Engineer > Setup > Process Operation Classes

Enter a class code and description

Enter a Valid From date as a validity rule for this operation. The default date is the current system date. Required. 

Enter a To date as a validity date for the expiration of this operation. If there is no expiration date for this operation, leave the field blank. 

Enter the Owner Organization for this Operation. A Description of the Owner Organization displays.

Minimum Transfer Qty displays the minimum amount of material that must be produced in a step at a specific production operation and resource before the next operation can begin. It is used by planning to reduce bottlenecks by letting processes transfer an interim quantity of completed material to the next step without the requirement to complete the entire step. 

Enter a Process Qty UOM for this operation. Required. 

Activities

http://kivancgedik1.blogspot.com.tr/2015/03/defining-activity-in-oracle-process.html

Enter an Activity required for this operation. A Description of this activity displays.

Enter the Activity Factor to specify the number of times the activity is performed in this operation. Required. For example, if a quality test must be performed at the beginning, middle, and end of a mixing time period, rather than defining the activity and associated resources three times, use an activity factor as the multiplier that indicates the number of iterations for the same activity. To indicate that the activity must be performed at the beginning, middle, and end of the mixing time period, enter a factor of 3. Factors are applied to usage of a resource when planning and calculating cost. Set the activity factor to zero to exclude a particular activity. You can also use this to select equipment used for a production run within this specific plant.

Sequence Dependency is selected when the activity has a sequence dependent setup. It is cleared when there is no sequence dependency. 

Enter the Offset Interval as the time delay from the start of the activity to the point where the resource is actually required. Required. 

Breakable indicates whether the activity can be broken. 

Max Break indicates the maximum duration of the break if the activity is breakable. 

Material Scheduled is used in conjunction with the planning and scheduling application to show the activity consumes material.

Repeat steps for each activity in the specified operation, and save your work.

To assign resources to an activity: 

Navigate to the Operation Activity window. 

Select the Activity to assign a resource. 

Click Resources. The Resource and its Description display. Throughput Process units of measure and usage units of measure are derived from the plant resource if one is defined. You can override these values using this window. A process quantity is converted to an operation process quantity unit of measure if needed. 

Throughput

Enter the planned Process Quantity for the resource. 

The UOM entered on the header displays. This is the unit of measure for the planned process quantity.This value combined with the Usage quantity define the usage rate. For example, if a resource can mix 200 gallons per hour, enter 200 as the process quantity, 1 as the usage, and the unit of measure for hours.

Process Quantity UOM defaults from Process Operation Details window.

Enter the planned resource Usage. This is typically expressed in hours. Required. 

Enter the UOM as the unit of measure for the resource. Required. 

Usage UOM defaults from Resources.

Cost Information 

Enter the Component Class code. The component class is set up in the Oracle Process Manufacturing Cost Management application and defaults from the Resource. Required.

The following fields are display only: 

• Resource, its Description and the Component Class Description for the resource. 

• Cost Analysis Code and Cost Analysis Description for the activity. The code and description default from the activity. 

Scheduling Information 

Select a Plan Type for the displayed Resource and Description

Select Auxiliary for resources that work as companions with the primary resources to perform an activity in the Operation. These resources do not affect the rate of the Operation. For example, a primary resource in a mixing activity is a mixer with a throughput rate of 100 gallons per hour. An auxiliary resource is the worker who operates the mixer. No matter how fast or slow the worker is, the mixer rate remains at a constant 100 gallons per hour. 

Select Primary to indicate the rate determining resource. It limits or determines throughput.it is also referred to as the bottleneck or critical resource. There can only be one Primary per resource. 

Select Secondary to indicate the resource that replaces the primary resource when it is not available. This resource performs the same task as the primary resource. It is unconstrained, and it has usage. The Oracle Advanced Planning and Scheduling application does not schedule the secondary resource. Required. 

Enter the Count as the number of resources needed for the activity entered.

Enter the Offset Interval as the time delay from the start of the activity to the point where the resource is actually required. 

Select the Scale Type. Designate whether scaling is used to determine resource quantity. Scaling is defined as the proportional increase or decrease of resources. For example, setup and cleanup activities are usually not scaled, while manufacturing activities are scaled: 

• Select Proportional Scaling if the resources change in a ratio to the quantity of material being processed. 

• Select Fixed if the resources do not change, regardless of the quantity of material being processed

• Select By Charge if the resources change as a result of the number of charges specified.

Return to Process Operation Details window to change status by selecting Change Status from the Actions menu after entering all relevant information and saving the process operation with the default Status of New. Depending on whether workflow is enabled, a different set of statuses is available.
