Project Planning and Control Using Oracle Primavera P6 - Versions 8.1 & 8.2 Professional Client & Optional ClientFormatting the Relationships in Primavera P6 8.2

Relationships lines may not be formatted like in SureTrak, but unlike Microsoft Project they do not adopt the color of the predecessor activity which is often misleading.

  • The relationships may be displayed or hidden by clicking on the icon on the Activity toolbar or by checking and un-checking the Show Relationships box in the Bar Chart Options form, General tab.
  • The color of the relationship represents:

Ø  Red – Critical and therefore a Driving relationship,

Ø  Solid Black – Non-Critical Driving relationship and therefore has Free Float,

Ø  Dotted Black – Non-Critical Non-Driving relationship and has Free Float, and

Ø  Blue – a selected relationship and may be deleted.

  • A relationship is displayed on the Baseline bar, as discussed in paragraph 8.3, when the Baseline bar is above the Actual and Remaining bars in the Bars form. To place the relationships onto the Early bar, which is more logical, you should move the Baseline bars in the Bars form to below the Actual and Remaining bars in the Bars form.

  • Select a relationship line by clicking and it will turn to blue and an arrow  will appear, then
