Need inputs to get the source system owner and Source system Id values who loaded data through HDL

Content

Hi All,

Someone loaded Worker data(Worker,Workrelationship,Workterms,Assignments..etc) through HDL We need to correct some data for the same employees. We don't know the Source system Id and Source system owner values the person who loaded data initially.

In the HRC_INTEGRATION_KEY_MAP table I got the Source system Owner and Source system Id values for Person. We don't have Source system Id and Owner for WorkTerms,Workrelationship and Assignment .

Please suggest how to get the Source system Id and Owner for the remaining components. Can we correct existing data without Source system Id and Owner values through HDL? If yes, please share us the sample .dat file for my reference.
