I have extended an existing class from the Pega Marketing for Comms (PegaComm-Data-ProductHoldings). When I look at the Data Model view in the Data Explorer (App Studio or Dev Studio) I can only see properties inherited from PegaComm- and nothing from ProductHoldings. These properties bear no correlation to the exposed properties mapped through the Sources tab, and visible in the Records tab. I know the later are defined by the DataTableEditorReport, but where is the metadata for the Reuesable Fields.
Also, if I add a property via the ‘Data object:’ landing page it appears in the list, but if I add it as a property rule it does not show up. Where is the metadata for the list, and how can I modify the class to show more properties that were probably not added in the Data Explorer?
OK. A colleague has helped me to find this. The visibility of the fields is set by the metadata for Relevant Records - See Configure, Application, Inventory, Relevant Records. These are instances of Data-Tag-RelevantRecord.
This configuration appears to date to 7.4. There is an archived article here,
