    *Stock Days' Supply:*

    • The days' supply displays the number of days that a material will cover if only current plant stock is taken into account.

    • Starting from the current plant stock, the requirements are deducted one after the other along the time axis. This is done until there is a shortage (requirement > stock).

    *The number of workdays between todays date and the date of the requirement that causes the shortage minus one day. *The value after the decimal point is the ratio between the opening stock on the day of the shortage and the requirement on the day of the shortage.

    • IN your case it is already your shortage of 0.5 days of supply.

    First Receipt Days' Supply

    • The receipt days' supply indicates how many days a material will last

    .*The system takes current plant stock and specific, predefined receipts into account when calculating the receipt days' supply

    • You can define two receipt days' supplies.

    • This enables you to instruct the system to take the less binding receipt elements into account for the first receipt days' supply,

    • When we mean the less binding elements based on the business rule it can be defined like Pur req, STO , Planned order can be your First receip days

    • Like you can mention about the planned order, sto

    • In your case have +4 which means based on the 1st day receipt elements in your config you have 4 days of supply stock with you.

    Second Receipt Days' Supply

    • As explained above it is additional days of supply with few other Receipt elements as mentioned in the configuraiton.

    • take only the binding receipt elements (such as production orders and shipping notifications) into account for the second days' supply.

    • This will have a concurent receipt elements.

    • In youse case you have -0.5 which means based on the second days of supply receipt elements of your configuaratoin you are already out of stock for .5 days of supply.

    Also note:

    The receipt days' supply is not calculated, if current plant stock is negative.

    The receipt days' supply is calculated for a negative plant stock, if the next requirement is in the past
