Different Activity Start & Finish Date in MS Project from Imported file of P6

Good day,

Just bear in mind that if you work with decimals that P6 and Microsoft minimum decimal are not the same. This means if you work in 1/4 of hours that one of the sysyems will round-off the decimal.

You are very unlikely to get the same answer when transferring project schedules from one scheduling package to another unless they are very simple schedules.

The two main reasons are:

1. The import export routines are never perfect, especially from MSP to P6, and

2. All scheduling software packages have different algorithms and therefor give different answers with the same data.

I have published an article on my websites under Technical Papers titled "Importing Microsoft Project 2003 – 2010 files into Oracle Primavera P6 Version 7" this will give you some insight into the differences.

Things have not changed with P6 Version 8.

Hi Leonard,

Have you checked that your project calendars are the same in both Primavera and Project?

Often if the hours per day or week are inconsistent or the working days per month then this can throw the data out by a day or two on importing?
