Description
Program RFDZIS00 creates a customer interest scale (account balanceinterest calculation) in local currencyand a letter, whose contents you can specify.The correspondence contains:

• cover letter text


• item and balance information detailed according to your selections,


• an interest rate overview which you can also choose, and


• an interest amount overview differentiated according to interest rates.

Precondition
Requirements for calculating and posting interest are:
An interest indicator must be defined for the account balance interestcalculation and all further specifications must be made for thecalculation. You can also store the interest terms under an accountnumber, which then functions as the interest calculation indicator.Thus, you can store interest terms according to each account. Checkwhether this requirement has been fulfilled. For more information onthis, access the Implementation Guide within system configuration viaHelp. Proceed
The form used for interest calculation must be defined and stored inthe system. Check whether this requirement has been fulfilled.
Define your own forms if necessary. To do this, you can copy thestandard forms. The standard form is F_D_INT_SCALE_00. The textelements stored under the respective company codes in the paymentprogram are used.
Store the form names for your interest indicator.
IF &DEVICE& = 'SCREEN'
Proceed
ENDIF
Ensure that the required interest indicator is entered in the customermaster records the program should include in the interest calculation.
To post interest, define the account determination within accountingconfiguration, and store the document type to be used. To reach therespective initial screens within the system configuration function,select Goto.
Account determination occurs via the posting interface of application"0006" (customer interest scale). The following specifications arerequired:
You must first specify which account determination key the system uses.Maintain the account determination key "business transaction". For thisyou need to create at least one posting method for the interestreceived posting and the interest expense posting respectively. If youwant to use interest splitting, maintain a posting method for each ofthe following accounting transactions:
past period with post-entered value dates for minus debit interest
past period with post-entered value dates for minus credit interest
past period with post-entered value dates for debit interest
past period with post-entered value dates for credit interest
calculation period for debit interest
calculation period for credit interest
Allocate account symbols for the respective interest earned accounts orinterest expense accounts to accounts. Only the posting key is relevantto vendor posting. It is stored in the posting method. The entry in the"G/L account" field of account allocation is not relevant here(customer posting). Interest cannot be posted as a noted item.
Account determination is stored under the reallocated interestcalculation indicator when interest is calculated for specialtransaction types.
IF &DEVICE& = 'SCREEN'
Proceed

Output
The program creates correspondence listing the items for each vendor.The following lists are also created:


• company code overview


• additional log (optional)


• error log (if errors have occurred)

Procedure and Specifications for the Interest Calculation

Notes on Special G/L Transactions
You can calculate interest on special G/L transactions, excludingnoted items. To do this, you must fill theappropriate fields in the initial screen of this program. Using theentered special transaction type and the interest indicator (or accountnumber) in the special G/L transactions, the program allocates a newinterest indicator, under which the interest calculation terms are thenstored. This means you can calculate interest on special G/Ltransactions separately and with different terms.
The program cannot simultaneously process different transactions. Thus,you must run the program separately for each transaction.
Since there is only one "Date of the last interest calculation" in themaster record, you can only process the respective batch inputs,providing they are imported, if interest is calculated on alltransactions.
No special G/L transactions are processed by default.

Interest Posting and Account Determination
Interest posting is put into a batch input session if you have selectedthe "Post interest settlements" field . If you select the "interestsplitting" field, the interest postings in the past period withpost-entered value dates are reversed (minus debit interest and minuscredit interest), the debit interest and credit interest in the pastperiod with post-enetered values dates and the debit interest andcredit interest in the calculation period are posted. Otherwise, theprogram only posts the total interest.
Account determination is carried out via the posting interface. Referto the posting interface section to know which requirements to fulfill.
