Channel ATP periods

You can enter the allowed demand per plan period for an item in the Channel Master Plan (cpdsp5130m000) session, but LN checks the channel ATP per channel ATP period.

You can define the channel ATP periods in the Plan Item - Channels (cpdsp5100m000) session.

Channel ATP period length

Enter the channel-ATP-period length in the ATP Period Length field of the Plan Item - Channels (cpdsp5100m000) session. A channel ATP period is defined in calendar days. The channel ATP periods have a fixed length over the total planning horizon.

As a rule, a channel ATP period comprises several plan periods.

Reference date

You can specify a reference date in the Reference Date field of the Plan Item - Channels (cpdsp5100m000) session. This reference date indicates when the first channel ATP period must start.

If the reference date lies before the scenario start date, LN adds a multiple of the value of the ATP Period Length field to the reference date. The first channel ATP period starts at the first possible date after the start date of the scenario.

Note

The reference date is a fixed date. Rolling the scenario does not change the reference date.

Example

You use the following settings:

  • Reference date: Jan. 1
  • Channel ATP period length: 28 days. As a result, the first ATP period is: Jan. 1 - Jan. 28.
Channel ATP

LN accumulates the allowed demand of all plan periods with a start date in the same channel ATP period. Customer orders can be accepted for a channel, until all of the channel ATP in a channel ATP period has been used up.
