Datalog Write can only append and not replace record

[zigbee1]

I noticed that Datalog Write function only appends data to an existing datalog and did not replace the record set by Set Datalog position. That is very odd, is this by design or I missed something ?

Hi Zigbee1,

From the context help on LabVIEW, the Write Datalog Function "sets the current datalog position to the end of the file before writing". 
It also explains in the link below that you cannot overwrite a record after LabVIEW writes it to a datalog file.

Thanks for pointing out...

Yep, still keep my heart up for NI to offer modifying existing datalog files in the future..
