Hi Team,
I am currently working on creating a CJA dashboard for B2B Buying Group level reporting and Opportunity Funnel analysis. I have set up the schemas with relationships and created the datasets(with 10 records) before establishing the connection in CJA, with optional containers enabled for Opportunity and Buying Group. The connection details are provided in the screenshots below.
Unfortunately, the backfill processing for the profile dataset (person) has failed, and the backfill for the lookup and event datasets has been ongoing for more than 3 to 4 days. I have reviewed the audit logs related to the connection but couldn't identify the root cause.
Has anyone implemented a similar use case and encountered these issues? Could the complexity of having numerous schema relationships in the dataset be contributing to this problem?
