Impact of ATP Date

When an ATP check is performed successfully there is an impact of the ATP date on Earliest Start Time(EST), Planned Start Time(PST) , Planned Finish Time(PFT), Latest Finish Time (LFT) and Planned Delivery Date(PDD ).

The below table displays the Earliest Start Time(EST), Planned Start Time(PST) , Planned Finish Time(PFT), Latest Finish Time (LFT) and Planned Delivery Date(PDD ), when the ATP check is not performed:

EST PST PDD PFT LFT
5-Apr-07 7-Apr-07 7-Apr-07 10-Apr-07 11-Apr-07

When the ATP check is performed and in case the ATP Date is greater than the Planned Delivery Date then following is the impact of the ATP date:

  • The EST date is reset to the ATP date.
  • The LFT date increases by the same number of days as the difference between the EST and the new EST as shown in the table below:
ATP Date EST New EST PST New PST PDD New PDD PFT New PFT LFT New LFT
8-Apr-07 5-Apr-07 8-Apr-07 7-Apr-07 8- Apr-07 7-Apr-07 8-Apr-07 10-Apr-07 9-Apr-07 11-Apr-07 14-Apr-07

When the ATP check is performed and ATP is greater than PDD and the new EST is greater than PST date then following is the impact :

  • The EST date is reset to the ATP date.
  • The PST date is reset to the ATP date.
  • The PDD also reset to the ATP date.
  • The PFT date increases by the same number of days as the difference between the PST and the new PST.
  • The LFT date increases by the same number of days as the difference between the EST and the new EST as shown in the table below:
ATP Date EST New EST PST New PST PDD New PDD PFT New PFT LFT New LFT
8-Apr-07 5-Apr-07 8-Apr-07 7-Apr-07 8- Apr-07 7-Apr-07 8-Apr-07 10-Apr-07 11-Apr-07 11-Apr-07 14-Apr-07
