Batch Update

Select this to use the IO Selections program to indicate the forecasting options for a range (batch) of inventory items.

You can select this option without entering any information in any other fields.
Save Save your selections for the warehouse/stock code combination.
Warehouse Enter the warehouse for the stock item for which you want to maintain the forecasting options.
Stock code

Enter the stock code of the item for which you want to maintain the forecasting options.

A stock item defined as a Phantom part or as a Notional part (Stock Code Maintenance) cannot be processed.
Change Rev/Rel

Select this to change the revision/release of the item for which you want to maintain the forecasting options.

When you select this option the ECC History listview is displayed, enabling you to select the rev/rel your require.

This only applies to stock codes which are defined as ECC controlled (Stock Code Maintenance - Tracking).

General

This pane applies to the updating of IO options for an individual stock item.

Field Description
Stock code This displays the code of the stock item you are currently maintaining.
Stock code description This displays the description of the stock item.
Warehouse This indicates the warehouse for the stock item for which you are maintaining the forecasting options.
Warehouse description This displays the description of the warehouse.
Revision/Release This indicates the revision and/or release of the stock item for which you are maintaining the forecasting options. This is only displayed for items defined as ECC controlled (Stock Code Maintenance - Tracking tab).
ID number This number is automatically generated by the system when you update your Current min/max levels for the stock code/warehouse combination. Current min/max levels can be updated using the IO Stock Levels Modeling (Functions menu - Update Current) and IO Draft Levels Approval programs.
Forecast calendar Indicate the forecast calendar that you want to use for forecasting. If left blank, the company default is used - see Forecast Calendars.
Forecast algorithm

Indicate the algorithm to use when forecasting this item.

You can select one of the following algorithms:

  • {Use default}

    Select this to default to using the algorithm assigned to the company (Inventory Optimization Setup - Algorithms 1 tab).

  • Competition
  • Mean
  • Median
  • Moving average
  • Exponential smoothing with trend
  • Six period weighted average
  • Twelve period weighted average
  • Holt-Winters additive
  • Holt-Winters multiplicative

  • Annual seasonal profiles - unsmoothed

    If you select this option a zero forecast is suggested by the Batch Forecasting and Manual Forecasting programs when declining trend data would cause a negative forecast.
Replenishment item Select this to indicate that the item is a replenishment item. Although your selection here has no effect on forecasting, it can be used as a selection criterion by some programs.
Manual forecast Select this to indicate that the item is forecast manually.
[Note]

Items that are forecast manually, are excluded from batch forecasting by default.
User defined 1 - 6 These are free format fields which you can use to enter whatever additional information you require.

Sales History Proxy

This pane applies to the updating of IO options for an individual stock item. It is used to link an item (typically a new stock item) to an existing item that has history. Usually a new stock item has no history so an existing similar item with demand history can be used to for the new item.

Field Description
Use proxy for sales history

Select this to indicate that a proxy must be used to determine the sales history of the item.

This is typically used for the introduction of a new item where you know that the sales pattern of the item is likely to be similar to that of an existing item that has sales history.

Proxies should also be used for the introduction of new revisions/releases of ECC-controlled items (i.e. the proxy for the new revision/release will be the previous revision/release). To cater for this, proxies may be multi-level.
Stock code Indicate the stock item for which you want to configure proxy details.
Stock code description This displays the description of the stock code entered.
Revision Indicate the revision of the item for which you want to configure proxy details.

This only applies to ECC controlled stock items.
Release

Indicate the release of the item for which you want to configure proxy details.

This only applies to ECC controlled stock items.
Use proxy until Indicate the cut-off date until which the proxy can be used.

This should allow sufficient time for stable sales volumes to be achieved for the item.
Percentage of sales to use Indicate the percentage of proxy sales to use, enabling you to cater for different volumes between the proxy and the new item.
Reduce sales when forecasting proxy Select this when you believe that the introduction of the new item will affect sales of the proxy.

You should probably always select this if the proxy is being used for the introduction of a new revision/release.
Reduce proxy's sales after Indicate the date after which the proxy's sales history (not the sales forecast) should be reduced.

This delay allows the item that is replacing the proxy to reach its potential sales.

The proxy's sales history is reduced by the percentage specified in the Percentage to reduce proxy's sales field, after the date specified in this field.
Percentage to reduce proxy's sales Indicate the percentage by which you want to reduce the sales history of the proxy.

It may be that the replacement item will not replace the proxy entirely.

Algorithm Settings

By default, the algorithm settings used are those defined in the Inventory Optimization Setup program. The Algorithm Settings are used to design the conditions under which the forecasting formulae run.

Field Description
