Meier,

You want to stop the additional request for actions given the supply chain delays in lead times. You can update your Lead Times, by Vendor and Item No. You can also apply Dampener Period and/or Dampener Qty to eliminate these additional actions. Here are some Planning Parameter settings a definitions to help you reduce the requests:

The way in which the planning system controls item supply is determined by various settings on the item card or SKU, and settings in manufacturing setup. The following table shows how these parameters are used for planning.

Purpose

Parameter

Define if the item is to be planned

Reordering Policy= Blank

Define when to reorder

Time Bucket

Reorder Point

Safety Lead Time

Define how much to reorder

Safety Stock Quantity

Reordering Policy:

• Fixed Reorder Qty. plus Reorder Quantity

• Maximum Qty. plus Maximum Inventory

• Order

• Lot-for-Lot

Optimize when and how much to reorder

Rescheduling Period

Lot Accumulation Period

Dampener Period

Modify the supply orders

Minimum Order Quantity

Maximum Order Quantity

Order Multiple

Delimit the planned item

Manufacturing Policy:

• Make-to-Stock

• Make-to-Order

Define If the Item Will Be Planned

To include an item/SKU in the planning process, it must have a reordering policy otherwise it must be planned manually, for example, with the Order Planning feature.

Define When to Reorder

Reorder proposals are generally released only when the projected available quantity has fallen to or below a given quantity. This quantity is defined by the reorder point. Otherwise, it will be zero. Zero can be adjusted by entering a safety stock quantity. If the user has defined a safety lead time, it will cause the proposal to be delivered in the period prior to the required due date.

The Time Bucket field is used by reorder point policies (Fixed Reorder Qty. and Maximum Qty.), where the inventory level is checked after each time bucket. The first time bucket begins on the planning starting date.

The default safety lead time, in the Manufacturing Setup window, should be set to at least one day. The due date of the demand may be known, but not the due time. The planning schedules backward to meet gross demand, and, if no safety lead time is defined, the goods may arrive too late to meet the demand.

Three additional reorder period fields, Rescheduling Period, Lot Accumulation Period, and Dampener Period, also play a role in defining when to reorder.

Define How Much to Reorder

If the planning system detects the need to reorder, the selected reordering policy is used to determine when and how much to order. Independent of the reordering policy, the planning system usually follows this logic:

The quantity of the order proposal is calculated to meet the specified minimum inventory level of the item, usually the safety stock quantity. If nothing is specified, the minimum inventory level is zero.
If the projected available inventory is below the safety stock quantity, a backward-scheduled supply order is suggested. The order quantity will at least fill the safety stock quantity, and can be increased by gross demand within the time bucket, by the reordering policy, and by the order modifiers.
3. If the projected inventory is on or below the reorder point (calculated from aggregated changes within the time bucket) and above the safety stock quantity, a forward-scheduled exception order is Both the gross demand to be met and the reordering policy will determine the order quantity. At minimum, the order quantity will meet the reorder point.
If there is more gross demand due before the ending date of the forward-scheduled order proposal, and this demand brings the currently calculated projected available inventory below the safety stock quantity, the order quantity is increased to make up the deficit. The suggested supply order is then scheduled backward from the due date of the gross demand that would have violated the safety stock quantity.
If the Time Bucket field is not filled in, only the gross demand on the same due date will be added.

The following reorder period fields also play a role in defining how much to reorder: Rescheduling Period, Lot Accumulation Period, and Dampener Period.

Reordering Policies

The following reordering policies affect the quantity that is being reordered.

In addition to all this, if you NEVER want a PO to change or generate new request, on the Purchase Line add the field Planning Flexibility and set the field to NONE.

Hope all this helps.

Thanks,

Steve
