Partial Track-Out#

Estimated time to read: 8 minutes

Partial Track-Out is an operation that relates to Material, which is one of the most important objects in the system as it represents any raw material, inventory or work-in-progress (wafers, dies, modules, printed circuit boards, capacitors, etc.).

A Material is partially tracked out when only a certain amount of the original Material is required to be processed. This is quite common with large production orders that need to be broken down into smaller quantities and use the Partial Track-Out operation to split and track out materials for a more continuous processing.

This document will guide you through the setup of a Partial Track-Out scenario.

Overview#

A Partial Track-Out happens when a Material is tracked in at a Resource in a Step and only a fraction of the quantity should be tracked out to a new Material.

Scenario Setup#

To enable partial track-outs, follow the steps described in the table below:

Table: Steps to setup the Partial Track-Out related entities

After the setup of these entities is performed, you can process a Material and perform a Partial Track-Out at the configured Step. The steps below will help you to create the adequate scenario:

Step 1: Create context resolution entry#

You have to configure the system to allow partial track-outs at a specific context. The StepSplitTrackOutContext Smart Table provides a wide range of possibilities, and these allow you to define a different set of contexts to perform partial track-outs (depending on the needs of your process). You can define the following different contexts:

Table: StepSplitTrackOutContext Smart Table keys

This means you can define that partial track-outs can take place for a specific Step in a variety of possible combined contexts, depending on the resolution, and precedence key, which you define in the Smart Table. For more information on context resolution, see Smart Tables.

For each of these possible context definitions, you have to define three values that will be applied if the context is resolved:

Table: StepSplitTrackOutContext Smart Table values

As a quick example, the configuration below defines that a Split and Track-Out operation can happen at the Mixing Step and the Mixer-05 Resource, with the following characteristics:

• A Child Material will be created with Primary Quantity = 10 units. This value can be overriden due to the Enable Quantity Override property being set to true.
• The original Material, now Parent to the split Child Material, will remain in state In Process, with 10 units removed from the original Primary Quantity.
• The Material that will be tracked-out will be the Child Material of the main Material, and any losses will be incurred by the original Material.

Step 2: Enable Step for Partial Track-Out#

A vital property must be enabled in the Step to allow partial track-outs:

Table: Step relevant property

Scenario example#

Consider a Material MAT_0003 currently queued at the Mixing Step:

Dispatch the Material to a Resource configured to allow partial track-outs. In this case, Dispatch and Track-In are linked, so both will be performed at once:

After the Material is Processed, end processing by performing Track-Out. The wizard then opens a new page called Split Information, and the default value for quantity configured in the smart table is automatically filled-in:

As seen in the image above, the name of the Split Material to Track-Out can be automatically generated according to the Name Generated defined in this configuration /Cmf/System/Configuration/Business/NameGenerators/SplitAndTrackOut/. However, you can override it by entering a name of your choice in the Name field.

In this case, since the smart table definition allows you to change the primary quantity to track out, you can change the default value. You can also define whether the Child Material is put in a specific Container and position, provided the Container allows it.

Regarding losses, the definition of the smart table was to have the Parent (or In Process) Material incur the losses. Hence, apply a loss and check the result after the operation concludes.

After the operation is completed, the information for the split (Child) Material is displayed.

You can see that the Child Material is in the Processed state, in the same Step with a Primary Quantity equal to the value defined in the wizard:

Now you should check the main Material, which has the Primary Quantity calculated as follows:

New Primary Quantity = Original Primary Quantity - (Partial Track-Out Quantity + Loss Quantity)

You can finally confirm the genealogy of both Materials:

In short, this diagram represents the flow of a traditional Partial Track-Out operation:
