Duration Import Import Wrong

Bill

Hi,

I am importing a duration from access. The units are integers in the access
table but in project the values are too small. In Project Tools, options,
Schedule, Duration is set to days.

Any ideas please.

Hi Bill,

Most likely it is importing as minutes. I know when you save a project
file as an access database, duration is in minutes.

I hope this helps. Let us know how you get along.

Thanks Julie and apologies for the appalling typing. It was all done in a
bit of a rush as tea was ready!!!

Should I just multiply the access figure up to translate into minutes or is
there a better way?

Cheers.
Bill.

Bill,
Yes, but Project works with minutes at the database level. My guess is
that Project is interpreting the access values as minutes so when
displayed as days per the option setting they will indeed be very small.
You can either modify the Access database so that duration values are in
minutes or you can make the translation in Project.

To make the translation in Project, one way is to dump the imported
values into a spare text field (e.g. Text1). Then use a customized field
with a formula to apply the appropriate factor - normally this is 480
for standard 8 hour working days. For example, let's say the imported
value is in spare Text1 and that value is supposed to represent days.
You could put the following formula in spare Text2:
Text2=Text1*480
Then filter for all non-summary tasks and copy the contents of the Text2
field to the Duration field for all task shown in the filtered view. The
end result should give what you want.

Hope this helps.

John/Julie,

I have done a bit of testing in the query from which Project is getting the
data.

I have multiplied the Access based duration by 8 x 60 to translate into
minutes. By doing this a duration of 5 days became 2400 minutes.

Then importing into Project gives a duration of 0.5 days!!!

So can we conclude that the values are being interpreted as tenths of
minutes??

Regards.
Bill

Hi Bill,

A thousand apologies. In looking at the PJDB.HTM file I found
confirmation of what you have discovered. From the file:
============================
Duration values are saved as minutes * 10. Eight hours would be saved
as 4800 (that is, 8*60*10).
=================================

My bad, sorry :-(

The actual unit of storage of the duration is in "ticks" of 0.1 minute. So
2400 ticks = 240 minutes = 4 hours = 0.5 day if the "hours per day" option
setting is the default 8 hours per day.
