filter for those activities then select all of the activities

right clikc and select assign then select successor

then highlight the one you want to delete or highlight all of then then pess the red X on the right 

be patient 

Hi,

 

I am not sure which version of Primavera is being mentioned.

In P6, Select the activity, goto Relationship tab.. under Predecessor section, click the "Assign" button. The Assign Predecessors window opens up. After this move the cursor back to your original P6 window and select all the activities whose predecessors are to be deleted. Upon doing that, return to the "Assign Predecessors" window and press Ctrl+A. This will select all the activities in "Assign Predecessors" window. Click the Remove Button (there is a small red button on the right hand side of the "Assign Predecessor" window).

Repeat the same steps using "Assign Successors" window. You have now deleted all the relationships linked to the required activities.

A report is a fixed document, there you cannot make changes, is no substitute to a filter. Missing a filter for links where you can select the filtered and delete the links, not the activities, with a single click or where you can make changes such as changing lag calendar or lag amount at a single click, a very common need is an ABOMINABLE MISS. No excuse when the data is already on the database.

For many years users of Primavera products have been asking for a direct way to filter for links, I know as for many years I was a P3/SureTrak user. Primavera never delivered, I was hoping ORACLE/Primavera P6 would.

Rodel,

Tracing logic as to explore all links is impractical, the question is very simple same as you can filter for activities based on a selection rule you specify how within P6 you can filter for relationships based on a selection rule you specify?

Is a very simple question, I am not looking for other awkward and impractical ways. Missing links filters would be as insane as missing activities filters.

Rodel,

We are not looking to filter for predecessors or successors; I believe all software (even the worst of all) can do this as filtering for activities is among the most basic needs. What you mention seems like a filter for activities, we are looking to filter relationships to get a listing on relationships not a listing of activities; this is also a very basic need I have seen questioned at PP many times. How it is done within P6?

What differentiates Gantt chart to CPM are relationships, therefore filtering by relationships and being able to see in a concise manner all fields that define a relationship is crucial, same as activities. It is not a re-invention of the wheel, no adittional functionality, the data is already there, it is more about good and practical interface design. How can you filter for relationships, not activities, that have a calendar different to their successors and predecessors, how you filter relationships that are out-of-sequence, how you filter relationships, how?

You can determine out-of-sequence visually when connected activities are close otherwise not, in a thousands of activities job this might be unpractical. Actual dates lower than planned dates under resource leveling does not imply there is out of sequence occurrence, this is very common under resource leveling when you catch up using overtime or it just happened without breaking the rules of logic.

One of the issues with displaying relationship lines is that in complex jobs they are impossible to follow. I always keep the display of relationships lines toggled off except for very simple jobs I use as sample jobs but not for real life jobs, not even for my very small jobs of about 700 activities, in a few thousands activities job with an amount of links of about six times the activity count it got to be quite a mess.

It is impractical to select each link, one by one, in order to display a window that will tell me about the lag calendar, about if the link is out-of-sequence, about if driving or not, about the successors and predecessor to make sure I clicked on the right link when activities are far away on the display.

We are looking for relationship delete not for activities delete.

We can select the mutliple relations on the activity networ by holding the control key, but thetrick is do not select the relation ship arrow with mouse but select it by dragging the mouse across the arrow.

Hope this helps you...

Muhammad,
My apology, you are correct. There are some instance that it can highlight multiple relationship but not for all. Once mouse drag line cross the correct node it allow you to highlight multiple activities. Alternative is to use SDK. If you have MS ACCESS and linked SDK you can open TASKPRED table and filter to project ID. You can delete all records for relationship on the filter project.

Rodel,

Wouldn’t it it asks to delete the activities rather than relationships?????????

Kumar,
Click Activity Network icon then highlight all network box then press delete. This will allow you to delete all relationship in one go.
