Replenishment: Inclusion of Expected Receipts and Issues 

Use

Stock in stores can change from when replenishment planning is executed and the stock is available for sale in stores. Receipts and issues can be cause such changes. In replenishment planning, expected issues and receipts can be determined by the system and can be used when calculating requirements. In doing so, planned receipts and issues as per ATP (available to promise) and forecast sales can be taken into consideration in the calculation.

The time period for taking expected receipts and issues into consideration begins on the planning date and ends when the replenishment lead time ends. For articles with article-based Inventory Management in Materials Management (MM), the replenishment lead time is defined using article master data (replenishment lead time = purchasing department processing time + planned delivery time + goods receipt processing time). You can also define the relevant time period in replenishment planning for other articles.

Features

Receipts and Issues Based on ATP

To take planned receipts and issues into consideration, you must set the corresponding indicator in replenishment planning (Define Receipts and Issues Based on ATP). If the indicator has been set for an item, an availability check is executed for the article for this item in the store when the "Replenishment Lead Time" has ended. The available quantity calculated in this way represents corrected current stock which included the planned receipts and issues.

Using ATP, you can take purchase requisitions, purchase orders placed with external vendors, stock transport orders, and deliveries for stock transport orders as receipts into consideration in the planning run. Deliveries not referencing a system document cannot be taken into consideration. Issues (for example, reservations or sales requirements) are taken into consideration.

Planned issues and receipts can only be determined for articles with MM-based Inventory Management. Before you can use the ATP option, you must enter a check group for availability checks in the logistics data in article maintenance for the relevant article. Check groups for the availability check can be maintained in Customizing for Sales and Distribution. The check rule is defined internally for Replenishment as RP .

For a combination of check rule and check group, determine the ATP scope of check and use this to determine, for example, which documents are to be taken into consideration as planned receipts. You can make a setting that determines if the availability check is to be executed with or without a replenishment lead time:

This setting is included in the standard delivery. This has the advantage that if two replenishment runs are executed in immediate succession for the same article, requirements are calculated during the first run only. Planned issues (for example, sales orders) can, however, incorrectly increase current requirements.

In order that issues planned for the future do not influence current requirements, you can execute the replenishment check taking the replenishment lead time into consideration. In this situation, the ATP check confirms that every quantity is available at the end of the replenishment lead time because the quantity can be procured by that date. Therefore, the ATP check is called for the day before the replenishment lead time ends, using Replenishment.

Issues Based on Forecast Sales

If you ran a forecast of future sales, you can include these values as issues in the calculation. To do this, you must set the indicator Forecast Include Issues in replenishment planning.

In doing so, sales are considered from the time of planning until the end of the replenishment lead time. In dynamic target stock, sales from the end of the replenishment lead time for the entire range of coverage (normally for the next two goods receipts) are normally included in the calculation.

In replenishment planning, the system takes sales on a daily basis into account. If you use a different period for forecasting (such as a week or month), the system calculates average daily sales as follows:

daily sales = sales per period / number of working days per period
