Rework Material#

🔒 Material.Rework

🔒 Material.ReworkOverride

Overview#

This transaction is used to send Material to Rework. When a Material is send to Rework, once the Rework is complete, it returns to a pre-defined processing point in the Material current Flow. The decision to rework a Material is normally the result of an inspection in metrology steps, test results or quality gates.

Setup#

No special setup is required other than to meet the preconditions of the transaction. Remember that there must be at least one Off-Flow Reason applicable to Rework for the Current Material Step and a Rework path defined for the Material Flow Path. For more information on how to create a Flow, refer to the Flow section.

Preconditions#

  • Material is Active, is not In Transit and not On Hold.
  • The Material is not On Hold and not In Transit.
  • The Experiment Lock Id of the Material is empty or set to Track-In.
  • The Material State is Processed or Queued.
  • The new Flow Path must be valid.
  • There is a next Step defined for the Material in the current Flow and the next Step exists in the current Material Facility or, if there is no next Step defined, the Material is In Rework or Off-Flow and there is a Return Flow Path defined.
  • If the Step is being changed, there are no active Protocol Instances that contain the Material being moved and that have the property Inhibit Move From Step set to true.
  • There are Rework Paths defined for the Material current processing point (immediate parent Flow and Step).
  • Selected Rework Flow (Go To Flow Path) exists, is Active and Enabled.
  • Selected Rework Reason exists, is active and is currently assigned to the current Material Step and classified as applicable to Rework.
  • If the Product of the Material has any of these properties set to true, Apply Global Rework Limit, Apply Step Rework Limits or Apply Reason Rework Limits, then you must take the limits that were set into account, and there must be a Reason for the Rework of the Material.
  • If the next Step has different Primary or Secondary Units, there must be Product Units Conversion Factors defined for the current Material Product (and all Sub-Material Products).
  • There must not be any Material Time Constraint violated for the Material at the current context and transaction.
  • There must not be any required Future Action for the Material.

Preconditions for Bulk#

Note

All Materials will be sent to the same Temporary Off-Flow / Step and with the same Rework Reason.

  • All Materials must:
    • Be at the same Flow Path.
    • Have the same System State.

  • If a Checklist is required, all Materials must require the same Checklist.

    Note

    If the Checklist is Long Running, different Checklist Instances will be created. Additionally, if the Checklist is Immediate, it must not contain any conditional item.

  • If a Data Collection is required, all Materials must require the same Data Collection with the same Data Collection Limit Set and Data Collection Type.

    Note

    If the Data Collection Type is not Long Running After Track-In, no Data Collection Parameter must have the Sample Id set to Material Id.

  • Resolved Documents must be the same for all Materials.

Sequence Of Steps#

Step 1: Rework Reason#

  1. Select the Off-Flow button on the top ribbon and select Rework.
  2. In the Rework Material wizard, select a Reason which is applicable to Rework.

  3. If a Go To and Return Flow Paths are associated with that Reason, they are automatically pre-selected, otherwise the system will pre-select the Step where the Material is currently located. In any case, the Return Flow Path can be overriden. The Material will be sent to the Go To Flow Path and, once it reaches the last Step in that Flow, it will return to the Return Flow Path.

    Info

    Changing the configured Return Flow Path is only allowed if the Material.ReworkOverride security feature is enabled.

    Reworks can also be performed within existing Reworks. Depending on the Future Hold configuration, the Material may be put on hold.

  4. Optionally, enter a Comment.

  5. Select Rework to continue.

Warning

When a Rework operation is performed while the Material is in a non-sequential block, the system will discard the information about which of the steps have already been performed in that same non-sequential block. Upon returning to the non-sequential block, those steps must be repeated or alternatively marked as optional and skipped.

Step 2: Documents#

This step is used to display Documents which are associated with the transaction context. To open any Document it is only necessary to select a Document and choose View.

Note

This step will only appear if there are Documents linked to the Material or the current Step. Documents can be configured either through the MaterialDocumentContext smart table or directly in the Step Context View. For more information, see Create Document.

Step 3: Data Collection#

This screen is used to collect data from a pre-defined Data Collection.

  1. If the Material has a Long Running or Immediate Data Collection configured, a screen will be displayed where it is possible to fill out the Data Collection data. If the Data Collection is Long Running, data can be filled out later (partially or completely). If the Data Collection is Immediate, it must be filled out completely.

Note

This step is visible only when a Data Collection is associated with the current Material Context and when the Material is Top-Most. Configure Data Collections through the MaterialDataCollectionContext Smart Table or directly in the Step Context View. For more information, see Create Data Collection.

A Data Collection may be configured to send data to SPC, in which case one or more SPC Charts will appear.

Step 4: Checklist#

This screen is used to complete a pre-defined Checklist associated with the Track-In.

  1. The Checklist is Immediate and must be filled out completely.

Note

This step will only appear if there is a Checklist associated with the current Material or Step Context.Checklists can be configured either in the MaterialChecklistContext Smart Table or directly in the Step Context View. For more information, see Create Checklist.

It is possible to link an Immediate Checklist to a Data Collection. This means that when filling out the Checklist, you can also fill out the Data Collection, and the following is observed:

  • If all the parameters of the Data Collection belong to the Checklist, the Data Collection step will not be shown.
  • If only some parameters of the Data Collection belong to the Checklist, both steps must be shown so you can fill out every item you need.
