Hi,Looking through your datacapture the UniqueID is runtime generated from "marine_poc_get_unique_id.cgi". Can you verify if this cgi is not generating the same id for these three levels. If the Unique ID is same across - then it would overwrite Products with Cooling Systems and so on. Since UniqueID is the only primarykey set in the configs, the iwdeltracker may not distinguish them while the values are from the same DCR.
I am getting the next seq value from DB using the marine_poc_get_unique_id.cgi so Uniqueid is not same accross.
