Configure storage execution attributes

You can configure the storage execution options for an entity that is used to store multiple items and lots.

You can also configure the initial status of an entity, which indicates whether the entity is available to store items.

Auto Delete Zero Inventory

If selected, the inventory record for this storage entity is automatically deleted when the item quantity in the inventory becomes 0.

Allow Negative Quantity

Specifies whether to allow negative quantities to be stored in the inventory.

If not selected, the entity does not allow the quantities in the inventory to become less than 0 and the requested transaction fails.

Allow Multiple Items

Specifies whether different items can be stored at this storage entity.

Allow Multiple Lots

Specifies whether different lots can be stored at this storage entity.

Allow Dirty State

Specifies whether to allow the state for the storage entity to become Dirty when it becomes empty after storing an item.

This attribute affects the Initial Entity Status attribute. If this attribute’s option is not selected, the storage entity cannot have the status Dirty.

Indistinguishable Lots

If selected, the lots stored at this entity lose their identity in the MES system. For example, you might select this option if the entity is a bulk storage tank.

If you do not select this option, items that are stored in this entity are not distinguished by separate lots.

Movable

Select this option to indicate that the entity can be moved (e.g., pallets). The movable entity can be moved or transported throughout a plant floor.

If this option is selected, you must specify the location of the movable entity that holds the inventory items to transfer.

Location

The location where you want to move the movable storage entity. This attribute represents a different storage entity than the storage entity that is movable. The location of the entity specified here is used at run time.

For example, if an entity, such as pallet, is configured as movable, this entity (pallet) may be located at another entity/location (Warehouse).

This attribute is applicable only if the storage entity is configured as movable.

Maximum Capacity

The maximum overall quantity that can be stored in the entity. A value of 0 indicates that unlimited quantities can be stored in this entity.

Initial Entity Status

You can select the status that represents whether the entity is available to store items.

Available

Indicates the storage location is currently empty. When the overall quantity becomes 0 or less than 0 and if the entity cannot be represented as Dirty, then the status of this entity is automatically changed to Available and items can be stored at this storage location. Otherwise, the entity state would remain in the Dirty state.

Used

Indicates the storage location is currently used and this entity has a quantity greater than 0 in it. However, items can be added to this storage location.

Dirty

Indicates the storage location is currently dirty. After the storage location becomes dirty, items cannot be added to this storage entity until the entity is cleaned and made available for storing items.

The status of the storage entity change to Dirty, only if the entity supports the Dirty state.

To allow the entity to have the status Dirty, the Allow Dirty State attribute’s option must be selected.

You can use the MES Operator application to change the Dirty state of the entity to Available. For more information, refer to the MES Operator User Guide, or the MES online help.
