Supply Chain Policy

This document explains how to set up a supply chain policy in 'Supply Chain Policy. Open' (CRS709).

The supply chain policy controls the behavior of the creation and changes of the supply chain.

Parameters to set:

Program ID/Panel Field The field indicates...
CRS709/E Order link type

… which type of link to use when generating a supply chain and whether allocation should be performed according to the pre-allocated quantity, or according to the allocation type on the item warehouse record.

Alternatives:

1 = Pre-allocation link with automatic allocation according to the pre-allocated quantity at stock receipt.

2 = Pre-allocation link with automatic allocation according to the allocation type on the item warehouse record. Use option 2 when you want the pre-allocated quantity to be, for example, soft allocated at receipt.

CRS709/E Create in batch

… if planned orders should be created/updated interactively or in batch.

Select the check box if planned orders should be created/updated in batch.

CRS709/E Rem Sup chain p … if the supply chain policy should be remembered. The Supply Chain Policy that was used to generate the supply chain will be saved and used during upstream and downstream changes or during regeneration even if it is changed or removed in 'Item. Connect Warehouse' (MMS002).

Select the check box if the supply chain policy should be remembered and used during changes or regeneration on the supply chain.

If you do not select the check box, the supply chain policy will not be remembered and any changes or regeneration will not use the policy that was used to create the supply chain if it is removed or changed in (MMS002).

CRS709/E Stop supply chain explosion

… indicates if the supply chain will continue or will stop the creation of the acquisition order for the demand.

Alternatives:

0 = Always creates supply order for the demand.

1 = Does not create supply order but finds an existing order to link in the chain. Can find manually or automatically depending on the ‘Link existing orders’ setup.

2 = Same as alternative 1 if the demand is triggered by customer order or distribution order. If the demand is a demand order, it has a continuous explosion. Recommended ‘Link existing orders’ setup is 2.

CRS709/E Link existing order

… whether the supply chain automatically creates a new proposal, or if non-allocated quantities for existing proposals/orders are used.

Alternatives:

0 = No. New proposals are always generated by the supply chain.

1 = Manually. The supply chain never generates any new proposals. Instead, existing proposals /orders can later be manually pre-allocated to the supply chain.

2 = Automatic. The supply chain never generates any new proposals. Instead, existing proposals /orders are automatically pre-allocated to the supply chain (if an unallocated quantity exists).

Note:

You usually enter value 1 or 2 when you have a supply chain where you want Material Requirement Planning (MRP) to plan and lot size the lowest level, but still want to connect to a supply chain later.

CRS709/E Automatically find supply chain

… if releasing a supply proposal on the lowest level of a supply chain should trigger an automatic search to find existing supply chains to connect to.

This option is only valid when ‘Link existing orders’ is set to 1 or 2.

This can be useful when the lowest supply level is planned via MRP and forecast. Later, the customer order arrives, and supply chains are created. When the actual releasing of an existing supply proposal takes place, it automatically tries to find one or several supply chains to connect to.

CRS709/E FIFO link

… how a demand connected to a supply chain should find existing supply order proposals.

Select the check box if supply orders are considered first, and if not enough, supply proposals are considered. The search order is that earliest supply order is selected first.

If you do not select the check box, supply proposals are considered first, and if not enough, supply orders are considered. The search order is that the latest supply proposal is selected first.

Note:

This field is only valid if the ‘Link existing orders’ parameter is set to 2. Also, be aware that this parameter is considered only when creating a supply chain.

CRS709/E Multiple order links

… whether an item connected to a supply chain should be able to use existing supply orders/proposals that do not cover the required supply chain quantity.

Select the check box if the demand quantity can be sourced from several supply proposals /orders.

If you do not select the check box, then the entire demand quantity must be sourced from only one supply order /proposal.

Note:

This parameter is only valid if the ‘Link existing orders’ parameter is set to 2. Also, be aware that this parameter is only used when creating a chain.

CRS709/E Safety time control

… whether the supply chain should consider safety time when automatically connecting supply orders. Safety time in this context is the time before the actual demand date that a supply order should be completed.

Respecting safety time can be useful if the supplier does not always keep their delivery times.

Alternatives:

0 = Respect safety time

1 = Respect safety time for proposals only

2 = Do not respect the safety time.

Example:

A supply order due on Friday has two days safety time. A supply chain is created and generates a demand for that Friday. If alternative 0 is selected, the supply order is not included in the supply chain. If alternative 1 is selected, the supply order proposal is not included in the supply chain, but a released supply chain will be included. If alternative 2 is selected, the order is included in the supply chain.

CRS709/E Allocate stock

… whether the supply chain generation should try to allocate existing stock.

See Allocate Stock Parameters sections below for more information.

CRS709/E APS decision tolerance

… how a change in quantity on the top level should be exploded to lower levels for Advanced Production Planner (APP) proposals, and if the APP decisions made earlier should be kept.

The explosion setting on (MMS037/E) and (RPS999/E) normally determines if proposals with status 20 consider any product structure changes. That is, done through the MRP where re-explosion setting 2 means to re-explode APP planned proposals but keep the APP planning decisions. In the supply chain, this setting has some influence on the APP proposal management.

See the section APS Decision Tolerance Parameters below for more information.

CRS709/E Tolerance control

Select the check box if the Advance Production Planner (APP) planned proposal should be considered as a release order and therefore not be changed.

If you do not select the check box, then the APP planned proposal is removed and a new proposal is created.

See the APS tolerance field help in (CRS709) for more information.

CRS709/E Material upstream

... if a quantity difference must trigger an upstream quantity change in the supply chain.

For detailed information about the upstream rules, refer to the User Documentation Library - Supply Chain Order / Upstream Rules in Supply Chain.

Alternatives:

0 = No upstream change is to be performed.

1 = Only a decrease of the quantity is to trigger an upstream change.

2 = Only an increase in quantity is to trigger an upstream change.

3 = Both an increase and a decrease of quantity are to trigger an upstream change.

Note: The tolerances set up for the upstream rules on 'Upstream Rules. Open' (RPS380/E) determine if an actual change is made in the supply chain.
CRS709/E Upstream priority

… in what order the upstream quantity change should be performed.

Alternatives:

1 = By customer line/distribution order line priority

2 = By planning date

When the put away is finished marked, the received quantity is calculated upstream in the empty chain, to find the quantity that it corresponds to at the top level.

The top level quantity is then used for regenerating the supply chain. Since the lowest level of a supply chain can be connected to several supply chains, some sort of priority must be used to control the order and which supply chains should be regenerated.

CRS709/E Upstream date change

… indicates if an early or delayed supply should trigger an upstream date change in the supply chain. The triggering if performed when an order within a supply chain at a lower level is rescheduled. For example, a material plan rescheduling for a planned manufacturing order, a confirmation of a purchase order, a receipt of a manufacturing order etc.,)

Alternatives:

0 = No upstream change.

1 = Trigger upstream change when supply is delayed.

2 = Trigger upstream change when supply is delayed or rescheduled earlier.

The date tolerances set for the upstream rules on (RPS380/E) determine whether actual changes are made in the supply chain.

The early upstream date change function only applies for one-to-one relationships in the supply chain.

CRS709/E Date filter

… can be used as a filter for the following scenarios:

• An upstream date change should be performed.

• An APP planned proposal can be automatically moved.

If the delay of the supply order exceeds the date filter, an upstream date change is triggered. The delay of the supply order is calculated as the difference between the planning date of the demand, and the supply.

If an APP planned proposal in the supply chain must be moved, a check is made against this filter. If the planned move is greater than the filter days, the APP planned proposal is re-exploded. If the planned move is less than the filter days, the APP planned proposal is left as is.

Note that it is enough that one of either the APP quantity check, or the APP date check, is true for the proposal to be re-exploded.

CRS709/E Attribute model

… indicates the ID of an attribute model.

Attribute models are connected to items and used to set the attributes that can be connected to the item.

CRS709/E Rescheduling Method … indicates how the higher levels are rescheduled during upstream change.

Alternatives

0 = Reschedule the top level order by the same number of days as the order that initiated the upstream change.

1 = Perform forward scheduling of orders, starting from the new planning date of the order that initiated the upstream change. Option 1 is suitable if the supply chain contains distribution orders or internal customer orders that do not deliver daily.

Regardless of upstream rescheduling method, the top level order cannot be rescheduled more than what is indicated by the upstream rule date tolerance as defined in (RPS380).

Example

A manufacturing order receipt is delayed by one day, causing a distribution order in the supply chain to miss its weekly route departure. With option 1, this DO will be forward scheduled to the next route departure the next week, and a top level customer order is rescheduled out one week rather than only one day.
