Weigh and Dispense Material#

Material.WeighAndDispense

In order to be able to enter the weight manually, it's necessary to have access to the Material.WeighAndDispenseManual feature. In case it's intended to add an electronic signature at the end of the transactions, it's necessary to enable the Force signature option on the Material.CompleteWeighAndDispense feature.

Overview#

This operation is used to Weigh & Dispense ingredients or components of source Materials into a target Material.

As a naming convention, the Materials which are consumed are referred to as Source Materials and the consumed quantity is referred to as Consumed Quantity, whereas the assembled Material is referred to as Assembled Material.

Setup#

No special setup is required other than to meet the preconditions of the transaction.

Preconditions#

• The current user is associated to an Employee object.
• The Assembled Material exists and it is Active.
• The Assembled Material is topmost, its PrimaryQuantity must be >= 0 and < QuantityToAssemble of the BOM Instance Material. The BOM Instance System State must be Open and the Assembled Material SecondaryQuantity must not be defined for the Material (Null).
• The Assembled Material is not On Hold and not InTransit.
• The Assembled Material does not have Sub-Materials.
• There is a CurrentBOMVersion defined for the AssembledMaterial and the AssemblyType is WeighAndDispense.
• The Assembled Material must be InProcess (that is - it needs to be performed after Track-In and before Track-Out).
• Source Materials exist, are Active, Queued or Consumable and are not On Hold.
• Source Materials have the MaintenanceHoldCount = 0 and have not Expired (ExpirationDate >= CurrentDate Or ExpirationDate = Null) and (MaximumAssembleDate >= CurrentDate Or MaximumAssembleDate = Null), do not have Sub-Materials and must be in the Step defined in the BOM.
• Source Materials Floor Life must still be valid: Either Floor Remaining Life is Null OR (Floor Life Remaining Life > 0 AND Floor Life Counter State = Stopped) OR (Floor Life Counter State = Running AND [Floor Life Remaining Hours - (Now() - Floor Life Open Date) in Hours > 0] ).
• Source Materials must not have any open defects (Open Defect Count is zero).
• For all BOM Products, if the Material Reservation Mode is different to None:
  • If the Material Reservation Mode is Production Order, and the TopMost Material of the Assembled Material has a Production Order defined, the Source Material for the BOM Product must have the same Production Order associated to it.
  • If the Material Reservation Mode is Material Dependency, there must be an Active Material Dependency from the Source Material to the TopMost Material of the Assembled Material.

• For TopMost of Source Materials:

  • the PickListItemCount must be Null.
  • the IsInTransferOrderItem must be Null.
  • the Material Product InventoryLocked must be false.
  • the IsApproved must be different from false (could be null).

• Source Materials must not include the Material being Assembled.

• Source Materials must be in the same Facility of the Assembled Material and must be in the Step as defined in the BOM.
• BOM must exist and be Active or Effective.
• The BOM Products for which the Product's Is Discrete property can only be consumed in discrete quantities.
• If the properties EnableCheckIn and RequireCheckInForMaterialOperationsResource of the topmost Material are set to true and the user's current IsIntegrationUser property is false, there must be an Employee associated to the current user who is currently associated with the Resource.
• The Resource has an Instrument Service defined.
• The Electronic Scale Measurement Units must have a unit of conversion different from the Assemble Material Primary Units (converted within the Generic Table UnitConversionFactors) if the BOM Formula Type is Absolute, or to the BOM Units if the BOM Formula Type is Percentage.
• The selected Electronic Scale is a Resource which provides the service as defined by the Resource's Instrument Service. The Service is enabled at the Electronic Scale and enabled globally at the service. The Calibration Status must be Calibrated, must not be on hold due to maintenance, its system state must be Up, the Electronic Scale's Resource must exist and be Active and exist in the same Facility (not Area by design) as the Resource where the Weigh&Dispense will take place.

Sequence of Steps#

Step 1: Scale & Printer#

1. Once the Material is selected and the Weigh & Dispense wizard is open, proceed to selecting the printer to be used (values are taken from the PrinterTypePrintersContext/) Smart Table.

2. Confirm the Resource Details and select Next.

Step 2: Safety Information#

1. A consolidated list of all the potential hazards and protective equipment needed to handle the Assembled Material (gathered from all the BOM Products) is displayed. This list is also available for visualization purposes at any stage of the transaction.
2. Once reviewed, click Proceed to W&D.

Step 3: Weigh & Dispense Page#

1. In case the selected scale is disconnected, a warning sign will be displayed. Otherwise, you can proceed with the weighing.
2. The information regarding the ingredients to be dispensed will be displayed in the wizard. In addition, information on the Source Product, such as its required and dispensed quantities, as well as the Warnings and Documents (Technical and Safety Data Sheets) will be shown.
3. On the top of the page, information on the current operation will be displayed and instructions for the operator on the proper steps to take to continue the process.
4. If the current dispensed quantity is zero, it is possible to select the weighing method: Positive (default) or Negative. The positive weighing is additive and it measures the content of the target Container or ContainerType. On the other hand, the negative weighing is subtracting and it measures the source Material or Container. It is to be used when you wish to reduce the content of the Container, therefore reducing its weight. In this case, the weighing shown on the screen will be the weight amount that has been taken from the Container.
5. Proceed to choosing the Source Material and Container as well as the target Container and ContainerType. If necessary, check the corresponding Material details on the right-hand side panel.

6. In Positive Weighing, the Container tare will be shown. Click Set Tare and Begin to acknowledge the tare value and to begin the weighing. However, depending on the scale used, it may be necessary to enter the tare by hand. If the option Negative Weighing has been selected, click Begin Weighing.

   

   Note

   If the current BOM Product has a Quantity Calculation Rule set, after pressing the Begin Weighing button the system must call the defined rule, which will return the values for Lower Tolerance, Required Quantity and Upper Tolerance, expressed in the Units defined by the BOM. A visual notation will be displayed next to the BOM Product currently being weighed. If the rule returns an error, this will be presented to the user and the operation cannot begin. If the rule is successful, the values for Lower Tolerance, Required Quantity and Upper Tolerance will be updated on-screen and the user can proceed with the operation.

7. The ingredient's weight will be shown. If the weighed-in quantity is less than the required quantity, the button Partial Dispense will be made available. Click on it to dispense the indicated amount and the remaining quantity (to complete the required quantity) will be shown in a value bar. If necessary, repeat until the required quantity is achieved (or surpassed, depending on the lower and upper tolerance margins that have been defined beforehand in the BOM).

8. When the dispensed quantity matches (or surpasses) the required quantity, a label is automatically printed, so that the product can be identified.
9. Repeat the process for every ingredient listed in the BOM.
10. When all the BOM Products have been dispensed completely and successfully, click Complete W&D.
11. The system will require an electronic signature. Enter your credentials to complete the transaction.
