Use ATT inventory with or without lead time fences

Sometimes, a demand of a project attains high priority and requires immediate fulfillment, while the project has insufficient inventory and lead time fences prevent ATT cost peg transfers from other projects. When creating ATT cost peg transfers, the Enterprise Planning engine and the outbound process offset the replenishment lead times of a potential originating project against the issue date of the receiving project. If the replenishment date is after the issue date, no cost peg transfer is created and LN checks if transfers can be created from other projects.

Extend vs ignore ATT lead time fence

Lead time fences affect the availability of ATT inventory for permanent or borrow/loan cost peg transfers. You can ignore or extend the ATT lead time fences to create cost peg transfers in the preferred way.

The ATT lead time fence is calculated based on the order lead time of the item. In the Planned Order field of the Items - Planning (cprpd1100m000) session, the order lead time of the item is displayed. The default ATT time fence is identical to the order lead time. To increase the ATT time fence, you can specify the required values in the Additional Lead Time or Lead Time Multiplier fields of this session.

If you increase the ATT time fence for an item, the availability of transferable inventory is reduced for projects using the item. Although this results in fewer cost peg transfers, it also reduces the inventory available to fulfill short term demands.

Conversely, ignoring the ATT time fence increases the availability of transferable inventory. Also, the number of projects eligible for permanent or borrow/loan transfers increases. Each project from which inventory is transferred to another project can easily obtain a transfer from yet another project to fill its own inventory gap.

To enable the creation of ATT cost peg transfers regardless of replenishment lead times:

  1. In the Project Pegging Parameters (tcpeg0100m000) session, select the Ignore ATT Time Fence during Outbound check box.
  2. In the Cost Peg Transfer Rules (tcpeg1100m000) session, select the Use Available to Transfer check box.

Consequently, the outbound process creates permanent transfers for all excess or ATT inventory that belongs to other projects, and selects cost pegs to transfer from in the following sequence:

  • Excess inventory inventory
  • ATT considering lead times
  • ATT regardless of lead times

The Enterprise Planning engine ignores the Ignore ATT Time Fence during Outbound check box.

Borrow/loan cost peg transfers

If you also select the Borrow/Loan and Payback check box in the Project Pegging Parameters (tcpeg0100m000) session and specify Borrow / Loan in the Cost Peg Transfer Type field of the Cost Peg Transfer Rules (tcpeg1100m000) session for the relevant project ranges, the Warehousing outbound process can generate borrow/loan transfers for ATT inventory.
