    Awesome. As a person who has recently started these sorts of videos are going to be perfect. Honestly, youtube is filled with channels which are talking about the basics. One of the things which is my concern is about the company's that have a template and you don't have to do everything from the scratch. So what would you do if you want to add an activity between activities? You simply just put the activity between? What would you do with the relationships which exist right now? I mean the driving prodecessor and succesors.
    One of the issues that I had was, when I wanted to start to " activities" at the same time, and finish them at the same time as well.
    What would be the relation between those two activities?
    These sort of stuff are so much important that I personally had/have problem with.
    One of the other issues you could have added was showing the P6 baseline window and mentioning the data date and update box.
    These stuff seem obvious for you, but I think a person who has just started would have a problem knowing them.

      Thanks for watching, Abbas. If I'm using a template schedule to build from and want to insert an activity between two existing activities, here's what I would do:
      Activity A is currently linked to activity C with a finish-start relationship and I want to add an activity B in between the two. First, remove the link between activities A and C. Then, tie activity A as a predecessor to B, and B as a predecessor to C.
      Regarding having two activities occur at the same time: Let's say you want Activity A to start and finish at the same time as Activity B. Tie activity A as a predecessor to activity B using both a Start-Start and a Finish-Finish relationship. It'll be two relationships, but it controls both the start and the finish date to align with activity A (assuming both activities are the same duration).

      @@PJMScheduling Thanks PJ for taking time and responding to the questions that I had.
      One thing regarding having both SS and FF relationship in the predecessor, what would be the successor of that activity? Won't that be an open-end activity?

      @@abrajabpour That's correct. So you need to add a successor relationship with the next logical activity in the sequence to ensure you are not leaving it open ended.

    Hey PJ.
    Thanks for all the useful material, just a quick question, what is the difference between these three fields " Start" "Planned Start" " BL Project Start"
    I mean both, at the beginning of planning, and after some progress in the program and actualizing.

    • @PJMScheduling

      This is a great question and a little bit complicated.
      Start Date - This is a field in P6 where, on tasks that have not started, will show the "Early Start" date. But once the activity as begun, the Early Start date is then replaced by the Actual Start date. So, this field changes based on the status of the activity.
      Planned Start - In complete transparency, I do not have a good grasp of the Planned Dates and why Oracle has included them in the software. This is the best article that I've found to-date explaining the use and purpose of them, but I don't see the point in using them: www.planningplanet.com/blog/understanding-planned-dates-oracle-primavera-p6
      BL Project Start - P6 schedules have 4 different "slots" for you to compare schedule files. The slots include BL, BL1, BL2, and BL3. Using the "Maintain Baselines" feature in the Project tab, you can pull in many schedules to compare your opened schedule to. Then, you can use the "Assign Baseline" selection to specify which schedules you want to insert into the available slots (There is one Project baseline, and three "User" baselines). The Project Baseline (also referred to as BL), is the slot used if you are on an enterprise project system where multiple users have access to the same project file. When a Baseline is assigned to that slot (BL), it means that every user on the enterprise that is using the "BL" dates will show the dates for the activity that were from that specific schedule that is using that slot. Then there are three "User Slots" which are BL1, BL2, and BL3. You can, at most, have three baselines where you can view the data from a schedule that corresponds to the current file activity IDs. These dates will be specific to your device, even if you are on an enterprise, because each user on the enterprise can use the three slots whether someone else is using them or not.

    My manager after reviewing construction schedule on P6 commented “ several activities are riding the data date”. What does that means? Can anyone explain please

    • @PJMScheduling
      @PJMScheduling  6 หลายเดือนก่อน

      It means that all of the predecessors are completed for the activity. Therefore, there are no more active predecessors that are preventing that work from occurring. Only the data date is preventing the activity from occurring. This either means that the activity has to start immediately or should be re-tied to a different predecessor to give it a more accurate projected date.

      @@PJMSchedulinghow is the data date preventing an activity from happening, isnt the data date just a date to measure the past progress? For example if the data date is 15th April so the P6 data is telling us what was completed on and before 15th April right? So if the activity is schedule to start on the data date how is data date driving it.?

    • @PJMScheduling

      @@niheerthakur4128 You are correct, but all remaining work is calculated from the data date. If you move the data date from April 15th to April 20th, then all remaining work will be calculated based on the earliest start date of April 20th. For example, if you have an activity with no predecessor relationship, and you calculate the schedule, the start date for that activity will be equal to the data date. That is essentially what is happening when your manager says there are activities "riding the data date". All predecessors have been completed for that activity and, as a result, the projected start date for the activity is equal to the data date.

      @@PJMScheduling ok I understand it now but what is the right practice to follow here to avoid this. I mean if the predecessors are complete and the current activity should now ride the data date. What should be done here or is it nothing wrong to have activities riding the data date?

      @@niheerthakur4128 It depends. If there is literally nothing preventing the activity from starting and it is simply not getting done because it's low priority, then it's fine to let it ride the data date. But if it's riding the data date due to inaccurate logic, then I would tie the activity to an appropriate predecessor so that it is scheduled to start when you plan on getting work done.
