So if the request is made between start and transfer1 (REQUEST_TS 1) it has the startDivision ( CB1 ), if it's between Transfer 1 and 2 (REQUEST_TS 2) it's the division in the transfertable for the first transfer (CB 5). if it's between Transfer 2 and the END (REQUEST_TS 3) it's the division in transfertable for the second transfer( back to CB1).
It's also possible there are no transfer then it's the startDivision.
How do i create a table with these tables were i can give each request a correct division and will it be possible to do this on big files?
