      For all your basic queries please refer SAP Help. Assuming that you are taking the PS course from an authorized institute i would suggest you to ask your doubts to the trainer.

      Basic queries are rarely answered in this forum. The best place to clarify your doubts is through SAP Help.

    I am not against other people's posts, but to clarify you and to my knowledge:

    Earliest date (Start or Finish): refers to how soon an activity can Start or Finish per your schedule

    Latest date (Start or Finish): refers to how late an activity can Start or Finish per your schedule

    And, as others suggested, you need to refer to baiscs of scheduling to understand on how scheduling works in SAP. Forward/Backward pass, Critical path, TF (Total Float) & FF (Free Float), Lead-Lag relations are few other essential things to know.

    Hi,

    Earliest Dates:

    I give a start date of the project (or network) to let the program calculate wann a certatin activity will start using that start date.

    => Forward scheduling determine the earliest date2.

    Latest Dates:

    I known that deadline of the project (or network), I use this finish date to let program to calculate wann a certain activity need to be finished to fullfil the deadline.

    => Backward scheduling determine the latest dates.

    If the latest dates of an activity is earlier than the earliest dates, =>negative float, so either you should start the project (or network) more earlier, or you need postphone the deadline.

    => see consulting note 151551 about scheduling topic.

    Kind regards,

    Zhenbo
