Conditional Formatting or a Specific Filter Rule

Oliver's Power Query is really nice but I think it is missing the txNumber=3 lines (I'm betting he can tweak it to include them)

Here is a formula I used as a helper column:

=IF([@txNumber]>1,
      [@tbSize],
      IFERROR(LET( r,ROWS(Tabelle1[[#Headers],[tbSize]]:[@tbSize])-1,
              PRODUCT(TAKE(FILTER(
                      HSTACK(DROP([tbSize],r),DROP([txNumber],r)-1),
                      [@dlHarqProcessIndex]=DROP([dlHarqProcessIndex],r),
                      {0,0}),1))),0))

the output is 0 if it isn't one of the resent lines or the tbSize value if it was (replacing this with just TRUE/1 would make the formula a little more simple but wanted it as a double check)

as for my method (which may be flawed) was to include all lines that have a txNumber>1 or if it is 1 then look for the NEXT line that has the same HarqID and if that line has a txNumber>1 then include it (i.e. next time that HarqID is used was a re-transmit).

I will try to attach the file separately
