Hey Prasad,

 

Windchill has several objects under Change Management Module below list gives you some of the most commonly used objects

 

RE: What are the object are in change management

 

 

  • Change Objects:
    • Modeled Data Types that encapsulate relevant information from the formalized steps of the Change Process
    • Change Objects are related to other Change Objects through link classes
    • Change Object primary types (Light green boxes in the image):
      • Problem Report / PR : class wt.change2.WTChangeIssue : Table WTChangeIssue
      • Change Request / ECR : class wt.chang2.WTChangeRequest2 : Table WTChangeRequest2
      • Change Notice / ECN : class wt.change2.WTChangeOrder2 : Table WTChangeOrder2
      • Change Activity / Change Task / Implementation Plan / CA : class wt.change2.WTChangeActivity2: Table WTChangeActivity2
      • Note:
        • In “flexible mode” Problem Report Change Request and Change Notice all inherit of a common Change Object type
        • This makes the data model more flexible in the configuration possibilities
    • Change Object link types (Dark blues connectors in the image):
      • Most commonly used Change Objects – PRs, ECRs, ECNs, CAs – are linked using the following link classes
      • IncludedIn2 : Links Change Notice / ECN — to — Change Activity / CA: Table IncludedIn2
      • Flexible Change Links: Links flexible Change Objects — to — flexible Change Objects
        • Flexible change links are used to link the new flexible Change Objects together
          • Ex: Problem Report, Change Request and Change Notice
          • Links are very generic/flexible
          • The relationship is configurable
        • Configurations can be restricted by Business Rules:
          • Includes which dedicated Change Object is roleA and which roleB, cardinality …
        • There are two types of flexible change links:
          • Change Process: Table ChangeProcessTable
            • Configures which objects link together as part of the same change process e.g. ECR to ECN
            • This influences which object types are available in the Associated Process Objects table
          • Change Reference: Table ChangeReferenceTable
            • Configures which objects link together as the reference, but are not necessarily included in the same process
            • This influences which object types are available in the Associated Reference Objects table
  • Changeables:
    • Objects that can be changed by associating them with a Change Object
    • Changeables are not a real object type stored in the database but are more a logical classification of object types in Windchill
    • These objects all implement the Changeable2 java interface
    • Common types include
      • EPMDocument
      • WTPart
      • WTDocument
    • Links between Change Objects and Changeables (Light blue connectors in the image):
In common usages: an Item that needs to be changed is associated with the Change Activity
  • AffectedActivityData : Links Change Activity / CA — to — Changeable to be changed: Table AffectedActivityData
  • ChangeRecord2 : Links Change Activity / CA — to — Changeable that resulted : Table ChangeRecord2
In addition to the Change Activity:
  • Changeables can also be linked to other Change objects using the following types of associations
  • Note that these types of associations provide contextual information for the change
  • Ultimately, the Object that must change and the Object that has changed are indicated by items linked to CAs
    • ReportedAgainst: Links Problem Report / PR –to – Changeable: Table ReportedAgainst
    • ProblemProduct: Links Problem Report / PR – to —  WTPartMaster types only: Table ProblemProduct
    • RelevantRequestData: Links Change Request / ECR – to — Changeable : Table RelevantRequestData
    • SubjectProduct: Links Change Request / ECR – to —  WTPartMaster types only: Table SubjectProduct
