Flows with Change of Material Between Cases

This analysis rule includes the flow elements that have changed materials between the current and the previous case. This change is significant and can indicate the following:

  • A change in operations, such as a line up change
  • An error in data or data communications

The following table lists a sample log output for this analysis.

Analysis Method​

  1. Collect a list of all flow elements for the current and previous Case that satisfy the following criteria.
  • Status Attribute value is IS (In Service).
  1. For each flow, test that the value of the material Attribute is different between the two cases.
  2. Write to the log section of the case. Report the violating flow information.

Configuration Using the Wizard​

The configuration of the Flows with Change of Material is a selection of the General Gross Error Analysis Rule. You open the window for configuring the test (shown in the following figure) from the General Gross Error Analysis Rule Wizard.

  1. Open the Gross Error Configuration window as described in Configuring - General Gross Error Analysis Rule.

  2. On the Flows tab, select Flows with change of material between cases.

    A Flows with material change - Attributes window opens.Figure 405: Flows with material change - Attributes window

  3. Select the Attributes according to the following table:

    Attributes

    SelectionsDescription
    Flow MaterialThe material name in the flow. The default is 'Material'.
    Material TableMaterial table name. The default is 'SF_Material table'.
    Material ColumnName of the column in the material table that contains the material. The default is 'Material'.
    StatusFlow in/out of service status. The default is to 'ObjectStatus'.

  4. Click OK to finish the configuration.

    The text "CONFIGURED" displays next to the 'Flows with change of material between cases' selection.
