Storage unit properties

EquipmentId

The unique identifier for the equipment that the item represents. If you do not assign an equipment ID to the item, AVEVA™ Production Management checks each subsequent parent folder and uses the first equipment ID that it finds.

String

EquipmentIdentifier

The unique identifier for the equipment from an external system. For example, equipment in SAP has an identifier. You enter the SAP identifier into the EquipmentIdentifier property so that AVEVA™ Production Management recognizes the SAP equipment. The EquipmentIdentifier cannot be the same as any other EquipmentIdentifier or LocationIdentifier.

String

EventMask

The Event mask to apply to Downtime items in this folder. This is location (FullName) of the masking downtime reporting point.

A valid Downtime reporting point located in the plant hierarchy

AllowedMaterials

A list of permitted materials for this work center. Only materials on the permitted list may pass through the work unit.

Click Browse (...) to open the Select Allowed Materials dialog box. When the LotGroupRequired value is Mandatory each of the permitted materials for the work unit requires an association with a material class.

Any defined material

AllowedMaterialClasses

A list of material classes that are permitted for this work unit. A material class contains a defined set of materials. All materials that belong to the material class are permitted for this work unit.

Click Browse (...) to open the Select Material Classes dialog box. Select the material classes that apply to this equipment.

Any defined material class

AllowNegativeBalance

Specifies whether the work unit supports negative balances. This property appears when the work unit has LotBehavior of Selective, LIFO, FIFO, or WeightedAverage.

True, False

UseQualityMovingForward

This property appears if UseQualityMovingForward is set to True on the work center to which the Material Quality reporting point belongs. Specifies whether the associated quality is moved forward through the destination fields.

True, False

QualityMovingForwardPriority

This property is visible only if the UseQualityMovingForward property is set to True. Specifies the preferred quality to move forward into the destination work center as either Weighted Average Quality (WAQ) or Material Quality.

This applies only when a material with Material Quality comes into a destination work center, and the source work equipment has a Weighted Average Quality.

When the quality you select to move forward does not exist for the material or the source work equipment, AVEVA™ Production Management uses the second quality option.

For example, if you select WAQ, and the source work equipment does not have a WAQ, then Material Quality is moved forward.

Weighted Average Quality, Material Quality

WeightedAverageRemnantMaxSize

Specifies the maximum size of a remnant lot. This property is visible only if the LotBehavior for the work center is set to WeightedAverage.

For example, a work center balance increases from 100 tons to 1000 tons, the WeightedAverageRemnantProportion is set as 25%, and the WeightedAverageRemnantMaxSize is set to 50 tons. The WeightedAverageRemnantProportion property on the initial balance determines the remnant lot is 25 tons, but the increase in balance determines the remnant lot as 250 tons.

The remnant lot is excessive in size, so the WeightedAverageRemnantMaxSize limits the remnant lot to 50 tons. The lot is considered a remnant lot only after the balance is equal to or less than 50 tons.

Integers

WeightedAverageRemnantMinAge

This property is visible only if the LotBehavior for the work center is set to WeightedAverage.

Specifies the minimum age for a lot, before it can become a remnant lot. You configure this property so that a lot does not become a remnant lot when it is first created.

A valid time span in the form hh:mm:ss

WeightedAverageRemnantProportion

This property is visible only if the LotBehavior for the work center is set to WeightedAverage. Specifies the percentage of the total work center balance at which point the lot is considered too small to use in a weighted average movement and becomes a remnant lot.

For example, if the balance of the work center is 1000 tons and the WeightedAverageRemnantProportion is set as 2%, then the lot becomes a remnant lot after the balance of the lot is 20 tons.

A percentage of the original lot balance

LotBehavior

Controls what happens to material lots when material enters or leaves the work unit.

Note: Specify the lot behavior that applies to add a lot reporting point beneath the work center. If the work center contains a lot reporting point, you are unable to change the LotBehavior type back to Mixed.

Mixed, Selective, Lifo, Fifo, WeightedAverage.

LotGroupRequired

Specifies whether a lot group is required or optional for this work unit. When this value is True, each of the permitted materials for the work unit requires an association with a material class.

Mandatory, Optional

ManageInventory

Specifies whether this work center manages Inventory and whether Inventory is visible in the client. When this work center is used by a material movement, the value automatically changes to True and cannot be changed.

When the value is True, define a value for AllowedMaterialClasses or AllowedMaterials, or a validation error occurs. If the value is False, you cannot use this work center in a material movement because a validation error occurs during processing.

True, False

ClassAssociation

The class that this item and children are associated with. A Class Association associates custom properties associated with the class.

You can associate this equipment with an equipment class. Click Browse (...) to open the Class Association dialog box, and choose from the list of available defined classes. The piece of equipment belongs to this class and displays custom property definitions in the Properties pane.

Any defined equipment class

EquipmentTypes

Specifies each equipment type from which the item inherits the relationship matrix.

Click Browse (...) to open the Select Equipment Types dialog box. Select one or more equipment types that apply to this item and sub-items.

Defined equipment types

RelationshipMatrix

The cause/classification relationships for this item.

Click Browse (...) to open the Relationship Matrix dialog box. Select one or more relationship matrices that apply to this item and sub-items.
