Hello,
I noticed some confusion w.r.t the question:
When can / does the ChangeHistory works for a given entity?
Let me provide some details:
Custom Business Objects
- With the annotation [ChangeHistory] the data of nearly any element and node can become part of the ChangeHistory :smile:
- As transient elements do not have a persistency they can not become part of the ChangeHistory :sad:
- For the Dependent Objects TextCollection and AttachmentFolder this annotation is not applicable
=> No ChangeHistory for the elements and nodes of the DOs :sad:
Extensions to SAP Business Objects
- Extension Fields are handled by the Extension Framework (EXF)
EXF does not support the annotation [ChangeHistory]
=> No ChangeHistory for Extension Fields :sad:
- Extension Nodes are handled by PDI itself; (nearly) the same functionality as in Custom Business Objects is available
- If the SAP Business Object is already supporting ChangeHistory
- The data of any element and node can become part of the ChangeHistory :smile:
- Except - of course - transient elements
- For the Dependent Objects TextCollection and AttachmentFolder the annotation is not applicable
=> No ChangeHistory for the elements and nodes of the DOs :sad:
- If the SAP Business Object is not supporting ChangeHistory this feature is also not available in general for the Extension Nodes :sad:
HTH,
Horst
