IDENTIFYING AND UNDERSTANDING THE REASONS FOR ORACLE PRIMAVERA P6 ROUNDING ERRORS

Many companies like to keep their schedules on a daily basis so that all activities start at the start of the day, finish at the end of the day and all durations are in round days. P6 does not have functions like the Elecosoft (Asta) Powerproject “Snapping” function that keeps all task to a round day, so users have to be more careful with Primavera P6.

There are two rounding errors issues:

  • Firstly, how do you identify that you have rounding errors, and
  • Secondly identifying what is causing rounding errors.

If you wish to learn how to identify and resolve P6 rounding errors then please read this article which is an extract from my 99 Tricks and traps for Oracle Primavera P6 Professional book  by clicking on this link>>>.

WHAT ARE P6EXTERNAL DATES?

P6 has dates that are called External Dates. Do you know that they are a constraint, they may significantly change your program and may be created without you knowing?

External Dates can be career shortening if you do not know how they are created, how to find them, delete them or turn them off!

If you wish to understand about External Dates then look at this paper with is an extract from my Planning and Control Using Oracle Primavera P6 PPM book by clicking on this link>>>.

Oracle Primavera P6 “Project Must Finish by Date”

An absolute finish date may be imposed on the project using the Project Window, Dates tab. Imposing a Must Finish By date makes Primavera calculate the late dates from the Must Finish By date rather than the calculated early finish date. Click on this link to see an article on how this P6 operates
