Inclusion of Expected Receipts and Issues
Use
The stock situation in a store can change between the replenishment planning being executed and the stock being made available for sale. Receipts and issues can 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.

Receipts and Issues Based on ATP
To take planned receipts and issues into consideration, you need to set the corresponding indicator in replenishment planning (Consider Receipts and Issues). If the indicator has been set for an item, an availability check is executed in the store for the article for this item when the "Replenishment Lead Time" has ended. The available quantity calculated in this way represents the current stock, corrected to include the planned receipts and issues.
Using ATP, purchase requisitions, purchase orders placed with external vendors, stock transport orders, and deliveries for stock transport orders, for example, are considered as receipts. Deliveries that are not connected with a system document are not included. Reservations or sales requirements, for example, are considered as receipts.
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. You can maintain check groups for the availability check 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 also set whether the availability check is 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 only calculated during the first run. 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 so that it takes the replenishment lead time into consideration. In this case, however, 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 have run a forecast of future sales, you can include these values as issues in the calculation. The system takes future sales into account if the forecast indicator + (compulsory forecast) is assigned to the RP type.
In doing so, sales are considered from the time of planning until the end of the replenishment lead time. In dynamic target stock, however, sales from the end of the replenishment lead time for the entire range of coverage (normally for the next two goods receipts) are 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
