Dataflow data volume mismatched

Hi there,

Would any one help me to understand the Dataflow loading volume please.

I set up Dataflow C linked to a table of Dataflow B, then Dataflow B use data from a table of Dataflow A. For some reason, the dataflow C didn't receive full volume load from original A. Curious and annoying about this bug, I added a side table called audit to count total from A passing to B (measure at A, and measure loaded at B).

Note: Dataflow A and B share same Workspace

Data showed no discrepancy

Now this audit table is pass to Dataflow residing in another workspace so that I could see if the loaded volume is preserved.

Now the data is different despite the fact that Audit table is refered directly. Thinking that C is not catching the latest refresh, I refresh C then open to view the data in the referred Audit table, yet nothing is changed.

I felt like the data loaded is lagged for some reason

So I go back and check Refresh history of Dataflow A
