SAP REFX : Security Deposit Agreement

Security Deposit :

A Security deposit agreement is created as a separate contrac specifying the amount of the security deposit that the tenant has to pay.

You can assign the security deposit agreement to a real estate contract.  For each contract type of the real estate contract, there is a specified contract type for the security deposit agreement. You can only assign contract types for which Security Deposit Agreement is the contract reference.

In Customizing, define contract types for security deposit agreements in the "Contract Types" and assign these contract types in another step to contract types that are used for security deposit agreements.

You also have to define security deposit types.The security deposit type, along with the form ( Pledge / Gurantee / Cash) of the security deposit, specifies how the contractee makes the security deposit. e.g., Bank guarantee, Bank comfort letter, Cash deposit, Real estate, Eligible securities. 

In security deposit agreements you enter the security deposit to be paid, and/or you can calculate the security deposit amount. The attribute of the security deposit type determines the representation of the security deposit agreement on the screen (the designated condition types are displayed on the first screen) and does not have any functional impact.
 
Standard Condition types - Security deposit calculated : The "calculated security deposit" is usually calculated using a calculation formula of a given condition group multiplied by x.
Agreed security deposit : The agreed security deposit is a fixed amount you enter manually.
