The cash security deposit is a cash payment at the beginning of a business relationship.
The cash security deposit can be cleared with the final invoice (industry solution Utilities).
The cash security deposit can be cleared or paid out as long as it is released.
The cash security deposit processing executes the following steps:
- The deposit is created manually or automatically (industry solution Utilities).
- The status is set to Requested after saving the deposit.
- The deposit request document is a statistical receivable.
- The deposit can no longer be used once it has been reversed.
- The deposit can be reversed as long as the request has not yet been cleared.
- The status changes to Paid or Partially Paid when you receive a payment, and this clears the request either completely or partially.
- The status changes to Released when the return date is reached or when an early manual release occurs.
- The status changes to Returned when the deposit payment is cleared either against a receivable (final invoice, account maintenance) or by a repayment.
You can use transaction FPSEC1 to create a cash security deposit.
You can use transaction FPSEC2 to change and release a cash security deposit.
You can use transaction FPD1 to display a statistical overview of all security deposits.
You can use event 0820 to create a payment form number automatically when you create a cash security deposit request.
You can use event 0860 to define follow-on actions for security deposits that meet certain criteria. For example, a clerk retrieves a noncash security deposit from storage if the return date is reached within the next week.
You can use event 1025 to automatically release and create cash security deposits when the payment method in the contract account changes.
For example, if a direct payer changes their payment method to bank collection, all of the cash security deposits in the contract account of the business partner are released automatically because there's no longer any reason to retain the security deposit.
If a business partner who has previously paid their receivables by bank collection becomes a direct payer, you can automatically request a cash security deposit.

When payment is allocated to the request for the cash security deposit, credit corresponding to the payment amount is posted to the contract account. The statistical request is cleared.

The payable resulting from the payment of the cash security deposit will be settled against the invoice receivable amount (account maintenance). In this example, the remaining amount after settlement is EUR 66.

The way in which the interest key for a cash security deposit payment is determined differs from the standard way to calculate interest on items:
If an interest key is specified in a payment, this is the one that applies.
If no interest key is specified in a payment, the system tries to determine a key from the relevant security deposit. If no interest key can be found, no interest calculation takes place.
An interest lock at master data level is not considered when interest on cash security deposits is calculated.
You can display posted cash security deposit interest on the maintenance screen of the deposit. Choose Environment → Interest Calculation List to display an overview of the interest run.
