Hi @ritesh.ranjan ,

can you please clarify what is the Sequence column?

A record is ingested into MDM.Instance layer only if there is at least one attribute/column changed.

Similarly the change is propagated to the Master layer only if there is at least one change on the master record itself i.e. based on your merge rules.

In other words if your Golden Record already exists and there is no update on that record even there is a related instance record changed, then it should update the date field on Instance Layer only and not on Master Layer as you mentioned. 

Please check if and how your Golden record changed.

Yes I think I agree with the previous comment. If the golden id exists and the update of one of the instances doesnt effect the fields on the golden id, based on the hierarchy youve assigned to the fields, then youre last update date on the golden id prob wont update. unless its maybe an action like a split or rematch that refreshes the master layer in some way. basically anything that would refresh the master layer specifically would be the cause for the last change update on master layer

Hi ​@ritesh.ranjan, I’m closing this thread for now, if you have any follow up questions please share them here or create a new post ‍♀️
