A product availability check is usually carried out at location level. If the requirement includes detailed organization levels (sublocation, version), a check is also carried out at these levels. The fewest number of levels of each check determine the result (confirmed quantity and date).

If you have set this indicator for a check of sales documents, you must also set this indicator again for a check of subsequent documents (delivery). Otherwise, the check could result in inconsistent confirmations.
You can find more information in the
Product Availability Check Using Checking Horizons section.The Past rcpts indicator controls whether past receipts (referring to the time of the check) can be used to confirm a requirement.
When posting goods receipts in Inventory Management, the checking horizon determines how far into the future (how many days) a check for shortfall quantities is carried out after the expiration of the checking horizon. For this to be carried out, you must configure the check using the checking horizon. You must activate the checking horizon first.
