| # Channel ATP periods You can enter the allowed demand per plan period for an item in the Channel Master Plan (cpdsp5130m000) session, but ERP Enterprise 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, ERP Enterprise 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 ERP Enterprise 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. Related topics Channels in Enterprise Planning Channel ATP |
